Historical fine-scale information of archaeological landscapes is crucial in archaeological investigations. However, documenting such information using satellite sensor data prior to 2000 remains a daunting challenge. Images from the declassified archives of KH-9 HEXAGON (KH-9) cameras, including the panoramic camera system (PCS) and mapping camera system (MCS), offer fine-scale information about archaeological sites. However, noise, contrast distortion and the availability of only a single panchromatic band can limit their potential, particularly for identifying features in subtropical climates within heterogeneous landscape types. This paper focuses on developing a novel multifaceted analytical framework with two components: image pre-processing and feature identification. The image pre-processing component is divided into two steps. First, a trained stationary wavelet transform (SWT) based on the normalized sill (NS) is developed to not only de-noises the image, but also preserve its original image characteristics. Then, the contrast of the de-noised images is optimized by the multi-resolution Top-hat (MTH) using multi-scale information. In the feature identification component, the MCS image is analysed using spatial colour composite write function memory (SCCWFM) and spatial novelty detection (SND). An ultra-fine spatial three-dimensional colour composite (UFSTCC) image and ultra-fine spatial digital surface model (UFSDSM) are produced to aid interpretation of the KH-9 PCS images. The proposed processing pipelines were tested on KH-9 MCS and PCS images of the World Heritage site at Liangzhu Ancient City (LAC) in China, which is characterized by a subtropical climate and a heterogeneous landscape types. The proposed pre-processing pipeline improved considerably the appearance of these images across the LAC landscape while maintaining the original image information. The developed digital analytical approaches for KH-9 PCS and MCS images facilitated straightforward identification of archaeological features in the LAC. The proposed framework has the potential to increase exploitation of the available KH-9 images in archaeological applications. [ABSTRACT FROM AUTHOR]

Traditional Chinese settlements (TCSs) embody millennia of human and cultural history, with the core culture serving as their essence. However, any damage incurred by these TCSs can result in the loss of core culture. In the era of China's digital transformation, there has recently been a significant push toward digital reforms within TCSs. Thus, this paper introduces a traditional settlement digitalization (TSD) framework with a specific focus on enhancing the preservation of TCS landscape gene through the perspective of landscape gene information chain theory. This research uses the Nanxun traditional settlement (TS), Huzhou, Zhejiang, China, the first TS listed as a World Cultural Heritage Site in China, as a case study, extracting and identifying the area landscape gene and digital visualization status. This article identifies the landscape gene information chain of the Nanxun TS and redesigns its digital visualization and application scheme under the TSD framework. This study reveals the notion of a digital landscape gene characterized by four key attributes: identical, interactive, immersive, and intelligent. The results of this study will help guide the sustainable protection, application and planning of the Nanxun TS and promote the study of other sections of landscape gene theory. This research not only contributes to the development of landscape gene information chain theory but also provides guidance for the digital transformation of other TCSs and cultural heritage sites.

Landscape stability is a paramount concern within the field of landscape ecology. Indices of landscape patterns not only facilitate an effective analysis of land use transformations but also delve into the mechanisms of landscape disturbances across various spatial and temporal dimensions. Utilizing land use data spanning from 2014 to 2022 for the Shibing and Libo-Huanjiang South China Karst (SCK) World Heritage Sites (WHSs), this study delves into the landscape dynamics of these areas over the past 8 years. This investigation employs landscape pattern indices and a moving window technique to construct a landscape stability evaluation model, incorporating indices such as the Contagion Index, Patch Density, and Total Edge Contrast. Moreover, the study employs Moran's I, a spatial autocorrelation index, to scrutinize the shifts in geographical heterogeneity of landscape stability within the said period. The findings reveal: (1) Between 2014 and 2022, the landscape patterns of the Shibing and Libo-Huanjiang WHSs have undergone significant transformations, with Woodland emerging as the predominant landscape type and its area exhibiting an upward trend in recent years. (2) The level of fragmentation within the research area has decreased, landscape diversity has diminished, and the aggregation index has risen, according to the landscape pattern indices from 2014 to 2022, indicating that conservation measures have significantly influenced the evolution of landscape patterns. (3) Throughout most of the study period, landscape stability predominantly remained at a relatively stable level, albeit with noticeable fluctuations in years heavily impacted by human activities. (4) The areas of high-high agglomeration and the hotspots of the heritage sites were primarily concentrated within the core zones of these sites, suggesting focused areas of conservation and landscape integrity.

The Huanglong Scenic and Historic Interest Area in China, a UNESCO World Heritage Site, is famous for its large-scale, diverse, intricately structured, and brightly colored surface travertine landscapes. However, severe degradation of the Huanglong travertine formations, such as blackening and algae erosion, has occurred in recent years, necessitating monitoring and identification. We collected hyperspectral reflectance data of the travertine formations in different states and bare ground using a ground-based hyperspectral radiometer (PSR-2500) from ASD company. After conducting a correlation analysis between the hyperspectral reflectance data and the travertine formations, we identified healthy travertine formations, blackened travertine formations, travertine formations affected by algae erosion, and bare ground. The Siamese network method was employed to generate data labels, and the spectral features of the travertine formations were extracted by combining the sensitive bands with pre-processed and reduced data. The PSO-BPNN classifier was developed by optimizing the back propagation neural network (BPNN) using the particle swarm optimization algorithm (PSO). To verify the effectiveness of PSOBPNN in accurately distinguishing different states of travertine formations, we compared its performance with that of BPNN using three performance indices. Finally, the proposed method was applied to the real-world hyperspectral image data collected by the Micro-Hyperspectral imaging instrument to classify the travertine formations in different states and bare ground. The test set demonstrated good overall performance, with an average overall accuracy (OA) of 0.93, F1-score of 0.92, and Kappa coefficient of 0.97. [ABSTRACT FROM AUTHOR]

In the built heritage studies, the intricate web of social and selective processes that define heritage is evident. These processes are, in many cases, intertwined with the notion of scale, examplified through the production of heritage sites at the local, national, and transnational scales. While heritage and geography scholars have articulated the role played by scale in heritage-making and argue against a rigid, fixed, and hierarchical understanding of scale, they highlight the constant reproduction of scale. There is, so far, limited explanation of how the perception of scale gets reproduced and how crucial actors manipulate scalar power and resources for heritage making and the reproduction of scale. To fill this gap, this paper delves into mainland China's heritage-making, using the southern Anhui historical villages as an example. Based on intensive 5-month field research, this paper has three findings: 1) The nomination process for a World Heritage Site is notably influenced by politics and selectivity; 2) Diverse stakeholders are pivotal in shaping heritage narratives; 3) Individual contributions to heritage creation directly interact with, and subsequently reshape, 'scale', an entity that is simultaneously discursive and tangible. By integrating the notion of 'scale' into heritage discussions, we illuminate two concurrent processes: creating hierarchies through rule assimilation by interpreting the UNESCO standard internally and evolving socio-spatial dynamics via the manifestation of individual agency with resource manipulation, scale jumping, and reproduction of scale. This approach aligns with the material orientation in human geography and repositions 'scale'. Here, it's not just an epistemological framework but also a tangible force that steers individual perceptions and actions and yields measurable material impacts. [ABSTRACT FROM AUTHOR]

The benefits provided by ecological assets play a crucial role in enhancing human well-being. However, there is a scarcity of viable methods for assessing their status. This study is grounded in Land Use and Land Cover Change (LUCC) and integrates both the quantity and quality aspects of these assets. Utilizing the ecological asset index (EQ and EQi), this study conducts a quantitative assessment of the assets in the Shibing karst and the Libo-Huanjiang karst heritage sites, while also qualitatively analyzing their influencing factors. The findings reveal that: (1) In the Shibing heritage site, forest and impervious surface assets exhibited an upward trend, whereas cropland and grassland experienced a decline; meanwhile, shrub and water body assets remained relatively stable. The total area of assets rated as excellent or good increased by 95.371 km2, resulting in an EQ enhancement of 45.427. (2) Likewise, in the Libo-Huanjiang heritage site, forest and impervious surface assets demonstrated an upward trajectory, while shrub assets declined. Cropland, grassland, and water body assets experienced minimal variation. The total area of assets rated as excellent or good expanded by 168.227 km2, resulting in an EQ enhancement of 80.806. (3) The execution of a series of ecological protection projects and management plans for heritage site conservation primarily accounts for the enhancement of regional assets. Notably, ecological resources, socio-economic conditions, human resources, and conservation management policies serve as pivotal drivers influencing the alterations in heritage site assets.

Climate change has led to many catastrophic events. In summer 2022, southern China witnessed a record-breaking heat wave. For example, Hangzhou, the capital city of Zhejiang Province (China), experienced a 2-month period of extreme hot weather. Rock outcrops exposed to strong solar radiation and high temperatures can experience rapid increase in temperature and repeated thermal cycles, which can affect the fabric and physical/mechanical properties of the rock and threaten the preservation of rock-hewn heritage. China has many examples of carbonate rock-hewn heritage with high historical and artistic value. Most are found in subtropical coastal areas with high heat and humidity, and where they might experience extreme high-intensity heat events in the future. Therefore, to study the impact of heat wave events on such examples of cultural heritage, a realistic heat wave aging test was performed in this study using samples of dolostone freshly quarried from near the West Lake Cultural Landscape of Hangzhou world heritage site. The nature of deterioration of the dolostone was evaluated using the capillary water absorption coefficient, surface hardness, and splitting tensile strength. The pore system of the dolostone samples was determined using the nitrogen adsorption method. Experimental results showed that the mechanical properties of the dolostone decreased moderately, while the water absorption capacity and porosity (micropores–mesopores) increased, indicating that high-temperature heating affects the physical and mechanical properties of dolostone to a certain extent. On the basis of the rapid rate of global warming and the increasingly frequent occurrence of extreme high-temperature events in China, the influence of thermal cycling on rock-hewn heritage deserves further attention.

Wu-Yue, meaning five-mountains, refers to five sacred mountains in China. The sacredness of this cultural landscape was manifested through the religious activities centered in those mountains and the state rituals of imperial China. This sacredness became recognized in the global context in 2010, when one mountain became the physical context of a newly inscribed World Heritage Cultural Site that purported to be at "The Center of Heaven and Earth." However, the sacred mountain itself was deliberately excluded from the narratives justifying the value of this heritage. Drawing upon archival research and limited fieldwork, this paper argues that although both Wu-Yue and "The Center of Heaven and Earth" are manipulated cultural concepts heavily charged with political agendas, significant differences exist between the processes of making these two heritages, the players involved in such processes, and the consequences of the socio-politically produced space. Wu-Yue, representing the ideological construct of the state power, was gradually established and constantly redefined over 3000 years through evolving ritual performances and cultural practices. In contrast, "The Center of Heaven and Earth" was created between the 2009 and 2010 sessions of the World Heritage Committee, yet with an embedded new political agenda: modern China, represented by a historical capital of imperial China, has become the center of the known world, from which a new global power is ascending.

Wooden figurines were excavated from the tomb of the Princess Yongtai of the Tang Dynasty. A series of analytical techniques were employed to understand the craftsmanship of wooden figurines during the Tang Dynasty. The pigments, cross-sections, and adhesives were analyzed using energy X-ray fluorescence spectrometry (EDX), micro-Raman spectroscopy, polarized light microscopy (PLM), X-ray diffraction (XRD), and pyrolysis–gas chromatography–mass spectrometry (Py–GC/MS). The results demonstrate that the pigments were primarily cinnabar, malachite, azurite, goethite, carbon black, and anglesite. The cross-sectional images show that the painted layer of the wooden figurines includes pigment and preparation layers. The main component of the preparation layer was mendipite. Chinese wax, animal glue, and benzoin were used as adhesives. This study provides scientific support for antiquarians and a basis for the protection and repair of this valuable world cultural heritage site. [ABSTRACT FROM AUTHOR]

The Lijiang River Basin is a humid, subtropical, karst landform in China and is listed as a World Heritage Site. However, with the rapid development of urbanization and tourism activities in recent years, it faces increasingly severe non-point source pollution. To understand the temporal and spatial variations in nitrogen and phosphorus pollution discharge and the changes in river water quality, the Jingui Small Basin, in the upper reaches of the Lijiang River, was chosen as a representative system. Changes in nitrogen and phosphorus concentrations were continuously monitored in the main river channel and the river water quality was evaluated using the comprehensive water quality identification index method. The results indicated that there were obvious seasonal changes in nitrogen and phosphorus discharge loads in the basin. Both nitrogen and phosphorus discharge loads were higher in the crop-growing season than in the non-growing season. No significant difference in nitrogen and phosphorus discharge load between different scales was found, and the scale was not the key factor affecting the nitrogen and phosphorus discharge load of Jingui River. As the river flowed from the initial water source to the outlet of the basin, water quality was characterized by the spatial pattern of the upper reaches > the middle reaches > the lower reaches. Except for the water quality at the outlet of the basin in November and December, which reached Class V, the comprehensive water quality of each sub-basin reached the target water quality of the water function zoning from May to December. The elucidation of the nitrogen and phosphorus pollution discharge patterns in the Jingui River and the changes in water quality provide a reference for the control and management of agricultural non-point source pollution in the Lijiang River Basin.

Jiuzhai Valley, a World Natural Heritage Site, was significantly damaged by an earthquake in 2017. However, case studies on the restoration of World Natural Heritage sites are lacking. This study aimed to use the box-counting method to analyze fractal characteristics of the terrain in Shuzheng Valley. Research data were used to conduct artificial intervention restoration of the earthquake-damaged terrain. Our results showed that (i) the travertine terrain shows self-similarity at different scales. The fractal dimension was related to terrain complexity: the more complex the terrain, the higher the fractal-dimension value; (ii) a combined form of fractal generator elements at the same scale was related to terrain complexity—differences in the spatial combination of the fractal generator elements can be compared based on fractal dimension; and (iii) the newly restored dam terrain also showed fractal characteristics whose spatial combination form was similar to that of the surrounding terrain. The complexity of the terrain's fractal element combination may be related to the influence of surrounding environmental factors and the different ecological functional requirements. This study provides basic data for the near natural restoration of the Sparkling Lake travertine terrain after an earthquake and proposes new concepts and strategies for restoring World Natural Heritage Site terrains.

This article investigates the relationship between archaeological tourism, UNESCO World Heritage designation, and the social value attached to archaeological sites in China. It aims to provide novel insights into such connections by examining the impact of archaeological tourism on the social values that local communities place on archaeological sites that are in the process of becoming World Heritage Sites. In recent decades, the increasing commercialization of archaeological sites for tourism, combined with the growing influence of the World Heritage listing process, has had a significant impact on the lives of communities in close proximity to archaeological sites. One way to comprehend such an effect is to examine changes in the social values assigned to those sites by their local residents. This is due to the ability of tourism development to (re)create and modify such values attributed to archaeological sites by changing their function, capacity, quality, and meaning. The World Heritage listing process, particularly during the pre-nomination period, plays an important role in shaping the tourist transformation of these sites in preparation for World Heritage inscription. Against this backdrop, this article focuses on two archaeological sites that have recently obtained the World Heritage status: the Daming Palace archaeological site and the Huashan rock art area. By applying ethnographic approaches, the article illustrates the complex influence of tourism development and the World Heritage Convention on contemporary Chinese society, in order to encourage further reflection on the existing management and development mechanisms of archaeological sites in China and around the world.

• This review gives panorama of heritage digitization in China and categorizes digital twin techniques into six levels to address three specific tasks. • Terrestrial LiDAR and VR are the most prevalent digital twin technologies for decades, while sensor-based monitoring is recently prompted by policy incentives and legislations. • Most digital twin projects are dominated by public sectors, i.e., cultural management authorities, universities, and research institutes. • Efficient data utilization and the seamless integration of diverse data sources within cross-disciplinary collaborations are still challenging. Recent decades have witnessed digital twin as a toolkit to collect, process, and utilize graphical, spatial and other attribute data of cultural heritage. It has been widely applied on cultural world heritage sites in China, which have significant differences in ages, types, materials, and history of maintenance and conservation. Although specific cases are reported previously, a comprehensive overview is still lacking. This paper explores the association between digital twin and heritage conservation, classifying digital twin techniques into six levels to tackle three tasks: data acquisition, visualization and application. It systematically reviews Chinese heritage digitization practices, considering variations in complexity and purposes, and demonstrates typological and chronological characteristics as well as the composition of stakeholders.

The provision of cultural and tourism public services in tourism destinations exerts a substantial influence on visitor experience and their overall quality of life. The current study applied structural equation modeling to empirically investigate the relationship between perceived cultural and tourism public services of visitors and their quality of life. Additionally, the mediating effects of perceived value, expectancy disconfirmation, and satisfaction in the above-mentioned influence relationship was also explored. In order to collect data, a field survey was conducted in a world heritage site located in Nanjing, Jiangsu Province, China. A total of 550 questionnaires were delivered, out of which 518 valid questionnaires were retained for subsequent analysis. The results demonstrate that perceived cultural and tourism public services of visitors have significant and positive influence on their perceived value, and visitors' perceived value has a positive effect on their expectancy disconfirmation. Moreover, there is a strong and positive relationship between visitors' expectancy disconfirmation and their satisfaction and quality of life. Additionally, the mediating effect of perceived value, expectancy disconfirmation, and satisfaction exist, and these three mediating variables serve as full mediators. The present study addresses the theoretical and practical implications, limitations, and potential areas for further research. [ABSTRACT FROM AUTHOR]

Changes in the spatial pattern of land use are inextricably linked to the ecosystem environment, and the assessment of regional eco-environment quality can help provide sustainable and healthy development strategies for heritage management organizations. In this study, based on RS and GIS technologies, we quantitatively analyzed the characteristics of land use changes in the Shibing Karst World Natural Heritage site from 2000 to 2020, and introduced the regional eco-environment quality assessment index for quantitative factor analysis. The results show that: (1) The heritage site is mainly dominated by forest and shrub, with more aggregated cropland, and impervious surfaces in the buffer zone. The area of shrub has increased during the 20-year period, occupying 12.63% of the total transferred area. Cropland has been basically converted to forest, accounting for more than 60% of the total transferred area, followed by shrubs, which have been basically transferred to ecologically better land types. (2) By analyzing the attitude of motivation, forest, shrub, and water have positive values, while cropland, grassland, and impervious surfaces have negative values. Grassland has the largest absolute value of kinetic attitude, and the smallest is for water. The integrated dynamic attitude is basically maintained at 24%, showing a state of rapid and then stable land category conversion. (3) Over the past 20 years, the regional eco-environment quality index has been stable between 0.68 and 0.71, and shows a trend of rapid growth and stabilization, which is consistent with the comprehensive attitude. The conversion between cropland, forest, and shrubs is the main cause of ecological improvement and deterioration. Overall, the relevant conservation measures at the site and China's corresponding responses to global climate change have led to a stabilization and increase in the regional ecological quality of the site. The management measures of the relevant authorities have begun to bear fruit, but further promotion of the sustainable development of the site is needed to provide a scientific model for the conservation of other karst heritage sites.

Visitor crowding issues caused by over-tourism at World Heritage Sites (WHS) are increasingly prominent. However, related studies and management give less consideration to the uneven tourist spatial-temporal distribution within micro-attractions, ignoring the detrimental impacts of local crowding on WHS' sustainable development. Aimed at exploring local crowding within heritage attractions from a perspective of time-space, this study used video-based computer vision technology to analyze tourist spatial-temporal distribution, density, and carrying capacity at stationary points (spatial locations where visitors stay and gather), taking a case study of the Master-of-Nets Garden, a World Cultural Heritage Site. The results indicated that although the total visitor number was below the attraction's carrying capacity, visitors repeatedly and quickly crowded at stationary points and formed high-density clusters, exceeding stationary points' space capacity and causing spatial local crowding. When visitors' dwell time was 5, 12, and 20 seconds, the crowding index K of stationary points was 3.4∼108.5, 1.7∼42.9, and 0.5∼33, indicating the spatial local crowding effect was negatively correlated with the length of visitors' dwell time at stationary points. Our contribution provides an accurate understanding of local crowding in WHS by highlighting the impact of tourist spatial-temporal distribution on carrying capacity and spatial crowding and suggests visitor management recommendations.

"Home Beyond the House: Transformation of Life, Place, and Tradition in Rural China" by Wei Zhao is a book that explores the impact of urbanization and development on traditional rural homes in China. The author, an architect and cultural preservationist, is concerned about the destruction of old houses and the loss of cultural traditions and rural lifestyles. The book focuses on a village called Yanxia in Zhejiang and examines the villagers' conceptions of home, which go beyond the physical boundaries of their dwellings and encompass their connection to the land and local traditions. The author also discusses the challenges faced by rural residents when their homes are destroyed and offers recommendations for preserving traditional settlements while modernizing them. The book provides valuable insights into the factors that shape the sense of home and serves as a useful reference for understanding the renovation, modernization, relocation, and urbanization of rural architectural environments.

World natural heritage sites are some of the most important and valuable protected areas in the world, and their designation aims to give recognition to the uniqueness and protect the integrity of the sites, which are ofglobal outstanding universal value. Understanding the global uniqueness and value of natural heritage will help to better manage and protect them, support the functioning of ecosystems, and promote sustainable development of humans and nature. A systematic review was conducted to determine the potential for the Hainan tropical rainforest to become a world natural heritage site. Based on a large number of literatures,we took the native plants, animals and vegetation communities of Hainan's potential natural world heritage site(Hainan Tropical Rainforest National Park)as the research objects, and evaluated the global outstanding universal value of Hainan's potential natural world heritage site from the aspects of biological ecological processes such as vegetation types, species diversity, fauna composition and endemic species. The results are as follows:(1)Hainan potential world natural heritage site has 3 653 vascular plant species. There are 540 species of terrestrial vertebrates, which account for 10%-30% of the wild animal species in the country. This indicates that biodiversity in this area is extremely high.(2)The flora found in the Hainan tropical rainforest is unique. Vegetation on Hainan Island can be categorized in the Indo-Malay rainforest group, and within the Malay region, and vegetation is tropical in nature and has a common origin with the South China mainland. This is indicative of the transition between the South China flora into the Asian rainforest.(3)The plant species specificity of flora is lower, there are only seven endemic genera in the flora, and about one out of every 10 species is endemic to the island. Lower specificity shows some characteristics of continental origin and the flora on the island are an irreplaceable element of biodiversity, and make up a valuable ecosystem. This study clarifies the outstanding universal values of the Hainan tropical rainforest and makes the case using empirical scientific evidence for nominating this area as a world natural heritage site.

World Heritage tourism in China regulates conservation approaches employed across natural and built heritage sites. However, focusing on the revenue-generating potential of these sites sustains material authenticity and technical conservation methods. The outcome is a conflict between conservation and commercialization, where socio-cultural values are overshadowed by the process of museumization. Underpinned by critical heritage theory and a focus on intangible heritage, this research seeks to confront this conflict by examining the shifting conservation practice at the Humble Administrator's Garden (HAG), a World Heritage Site and Classical Garden of Suzhou, China. A mixed-methodological approach explores the interplay between architecture and landscape within its heritage conservation process, utilizing archival research, semi-structured interviews with HAG Management, and visitor journals. The study shows how HAG's heritage is shaped by visitors' personal experiences and emotions alongside expert interpretations, resulting in the foregrounding of diverse narratives that contribute to a holistic sense of place. Within its politicized system, the safeguarding of intangible heritage requires constant negotiation among the municipality, the market, and emerging narrators. Attempts to reinterpret its former heritage buildings demonstrate a changing conservation discourse as the site transitions from an exclusive literati estate to a multivocal space of cultural encounter. The study illustrates how a focus on narrative representation unifies architecture and landscape, reimagining centuries of literati culture. This makes conceptual space for considering how conservation management can inform a more holistic narration of 'place' at similar World Heritage sites via the foregrounding of previously silent stakeholders.

Huanglong ravine (a world heritage site) is famous for its calcareous sinter landscape. Influenced by geomorphology, climate, hydrodynamic conditions, and biology, the overflow of CO2 in the water causes CaCO3 to over-saturate, allowing for the deposition of calcareous sinter. Among them, microorganisms play an important role in the formation of calcareous sinter. In order to investigate the physicochemical characteristics and microbial diversity of Huanglong ravine water, we measured the water quality and analyzed the microbial diversity in Huanglong ravine water samples by high-throughput sequencing method. The results showed that the TP (total phosphorus) and TN (total nitrogen) in Huanglong ravine water were 0.2–0.3 and 0.46–2.09 mg/L, respectively. Most of the sampling sites were moderately eutrophication. The abundance of Acinetobacter (9.55–67.13%), Pseudomonas (5.67–45.94%) and Brevundimonas (2.26–8.89%) was higher. The microbial community of Huanglong ravine water showed some positive correlation with the TP and TN. This study helps to diagnose the causes of algal blooms in Huanglong ravine and provides a scientific basis for the conservation of Huanglong ravine calcareous landscape. [ABSTRACT FROM AUTHOR]

Restoration techniques were explored for the patterns, materials, and surface pigments of the pigments decoration art of Kaiping Diaolou and Villages, a world cultural heritage site in southern China. Field investigation was supplemented by scanning electron microscopy, microscopic Raman spectroscopy characterization, colorimetric tests, and tensile tests. Materials and concepts for the restoration of the Kaiping Diaolou pigments were analyzed. Raman spectroscopy was used to characterize the surface pigments display of pigments decorative patterns. The main colors of restoration included green, red, white, and blue. The green color was a mixture of colored copper arsenate minerals. The red color was made of hematite (Fe2O3). White was calcite, and blue was lapis lazuli or synthetic ultramarine. SEM revealed both pigments show similar flake flocculent section morphologies. UV accelerated aging experiments showed that the Ultraviolet absorber and antioxidants effectively inhibited the degradation of the interface matrix. The interface was less prone to cracking. The tension test showed that the bond stress reached a maximum value of 0.193 MPa at a curing temperature of 20 °C under 95% ambient humidity. The results provide strong evidence for pigment restoration in Kaiping Diaolou. This study also provides a scientific reference for the pigment conservation of other architectural decorations from the same historical period. [ABSTRACT FROM AUTHOR]

World Heritage Site (WHS) inscription has been considered as a certification of tourism quality since it is designated to properties with outstanding universal value. While it is hypothesised that the title can raise tourism attractiveness through signalling tourism quality, empirical evidence remains highly mixed. This paper tries to identify the causal effect by using unique daily city-pair tourist flow intensities from Tencent migration big data on two Chinese national holidays between 2015 and 2019 and constructing multi-dimensional fixed effects panel data models. We find that the WHS inscription does raise city tourism attractiveness. One WHS increases tourist inflow intensity by at least 6.7% up to around 10%. The tourism-enhancing effect is consistent under many robustness checks and displays some notable heterogeneity effects in terms of holiday types, days within each holiday and high-speed rail connections. These results suggest that WHS inscription could be a valid tourism quality signal used by tourism administrations to enhance city tourism attractiveness. [ABSTRACT FROM AUTHOR]

Sustaining karst landscape areas in World Heritage Sites under increasing human pressures and climate change is an emerging challenge. Growing evidence has highlighted the transition from traditional government-oriented regulation to the collaborative governance of different stakeholders in governing karst landscape resources. However, the complexity and dynamics of karst landscape policy and stakeholder networks are poorly understood. This study combined a legislative analysis, network analysis, and public survey to explore effective methods of karst landscape conservation in the Guilin World Heritage Site, China. The policy analysis showed that various national laws and local regulations have been enacted in China, but these regulations often focused on individual aspects of karst–human interactions. The network analysis indicated the complexity and relationship of networks in karst World Heritage Site governance at the national, provincial, and municipal scales. The majority of questionnaire respondents (65–89%) reported a medium and high level of karst landscape governance effectiveness. The insights in the present study may be valuable for other karst World Heritage Sites facing complex challenges, especially in developing countries. [ABSTRACT FROM AUTHOR]

Since the mid‐1980s, there has been a boom in world heritage site (WHS) inscriptions in China. Nevertheless, incumbent studies have not sufficiently explained why cities are enthusiastic about and capable of joining the boom. They tend to attribute such enthusiasm to the WHS values in heritage protection and tourism development. However, why stakeholders have motivations and opportunities to create the boom and what institutional environments support the craze are still yet to be answered. This paper investigates the boom through the concept of embeddedness to display how multi‐scalar institutional contexts in China stimulate and sustain WHS nomination. This study argues that the enthusiasm for WHS inscription is embedded in the political‐economic interests of stakeholders on different scales. At international and national levels, WHS nomination is regarded as a political tool to address diplomatic agendas, shape national honor, and balance regional development. On a local scale, WHS inscriptions can serve as a solid pretext for local states in China to fulfill their strong developmental imperatives and break financial constraints. These imperatives are embedded in China's transitional institutional environment, associated with power decentralization, central‐local fiscal rearrangements, and the top‐down system of cadre evaluation. In this context, local states are ambitious of initiating large‐scale development projects to boost local development. WHS nomination has become a pretext for local states to fulfill extraordinary development in tourism and other industries, such as the real estate industry. This study discloses the hidden political economy behind the WHS inscription boom using the cases of Wulingyuan and the South China Karst. [ABSTRACT FROM AUTHOR]

Heavy metal(loid)s are widely regarded as important environmental pollutants and have attracted extensive attention. In addition to such areas with frequent human activities as cities and industrial areas, the heavy metal(loid) pollution in remote areas lacking long-term monitoring data also deserves attention. In this study, Chinese pine (Pinus tabuliformis) in Jiuzhaigou World Natural Heritage was sampled to analyze concentration of Pb, Zn, Cu, As, Cd, Co, Cr, and Ni and to reconstruct pollution history. Source analysis and evaluation of the potential ecological risk of heavy metal(loid)s were also performed. Results showed that Jiuzhaigou has been polluted by heavy metal(loid)s at a relatively high level and concentrations were the highest at the location with intensive human activities (Nuorilang). Tree growth was inhibited by increased heavy metal(loid) concentration and this situation was more pronounced at high concentrations. The increased heavy metal(loid) concentrations were attributed to human activities such as forest logging, infrastructure construction, and tourism development. Heavy metal(loid) pollution reached a very high level of ecological harm at Nuorilang and a high level of ecological harm in Shuzheng and Heye villages. Overall, even at low concentrations, we demonstrated that Chinese pine can be used not only as a bioindicator for heavy metal(loid) pollution but also to infer pollution history over a relative long-term period and to enhance our understanding of the biogeochemical cycle of heavy metal(loid)s in forest ecosystems.

As a UNESCO World Heritage Site, the Grand Canal of China has a rich intangible cultural heritage along its route. The intangible cultural heritage of folk songs is an important representative. The study of its distribution characteristics and influencing factors is of practical and social significance for promoting the protection and development of intangible cultural heritage in relevant areas and the construction of the Grand Canal Cultural Belt. This paper uses the theories of musicology, geography, sociology, data statistical analysis and spatial analysis to analyze the distribution pattern of intangible cultural heritage items in the Grand Canal basin from the dimensions of geographical space and folk song genre, and from the perspective of natural and social conditions. The results show that the spatial distribution of folk songs in the Grand Canal basin shows a trend of "distribution along the river, two cores and two belts". Water system, landform and regional culture are the main influencing factors for the formation and dissemination of intangible cultural heritage of folk songs. At the same time, compared with the mountainous areas in western China, the economic and social development and frequent population flow in the Grand Canal basin lead to the diversified and unified musical culture characteristics of folk songs. Finally, this paper proposes the suggestions that the folk songs should be integrated into the local social and economic activities. [ABSTRACT FROM AUTHOR]

Community-based natural resource management (CBNRM) originally aimed to promote nature conservation through community empowerment, but this aim is not easy to achieve. To analyze the reasons and propose responses, this paper constructed an analytical framework for CBNRM based on the theory of socio-ecological system synergies. A mixed-method (questionnaires, interviews, and observations) explanatory case study of Feicui village within the Mount Huangshan World Natural Heritage Site in Eastern China was conducted. The research illuminates the complexity of the CBNRM initiative in Feicui village, which neglects socio-ecological system synergies, leading to a lack of connection between the benefits from and attitudes toward natural conservation and a loss of integrated resource management. This study responds to the incomprehensibility of CBNRM and provides important theoretical contributions to international debates on CBNRM by highlighting the essence of recognizing system synergies to avoid deviating from the original intent of CBNRM.

Government protected areas are the most dominant governance type in the global network of protected areas, but in recent years, a lack of research compared to indigenous and private nongovernment protected areas has become evident. Consequently, community-inclusive conservation strategies consistent with the advantages of government protected areas are unclarified. Focusing on 49 households living at the Mount Huangshan World Natural Heritage Site in eastern China, this paper uses qualitative research triangulation to explain the causality between community exclusion and local distrust of the protected area and builds an explanation concerning the political and economic context. The questionnaire data analysed from the configuration perspective were corroborated with interviews and archival data, presenting innovative and enlightening findings. Lack of participation alone does not elicit local protests against biohabitat conservation, and government performance determines the trustworthiness of the government protected area. When local households are unaware of the government's efforts, a "trust paradox" in which the households that receive economic gains distrust government PAs emerges. This is caused by the social expectations of the "responsible government" and the survivorship bias of the households who manage to succeed in profiting. Induced or mandatory community participation is needed to strengthen the indigenous perception of the link between local development and government performance. This paper proposes a new strategy for socioecological goals that is consistent with the advantages of government protected areas, the most globally dominant governance type for protected areas and the type employed by the largest number of countries. • Underparticipation alone does not elicit local protest against biohabitat conservation of government PA. • Good government performance is a sufficient condition for the trustworthiness of government PA. • The "trust paradox" in which the benefited households distrust PA is due to the social expectation and survivorship bias. • Induced or mandatory participation generates trust in PA if community is broadly consulted on economic and social areas.

The emergence of social media has revolutionized tourists' decision-making processes and behaviours. This study focuses on the effect of user-generated content (UGC) on tourist loyalty behaviour by examining structural relationships between destination image, satisfaction, revisit intention, and word-of-mouth (WOM) publicity. Data were collected from domestic tourists to Gulangyu, a World Heritage Site in China. The findings of this study reveal that UGC indirectly affects tourist loyalty behaviour by influencing destination image and satisfaction. Moreover, the results demonstrate that factual UGC and emotional UGC positively affect tourists' perceived value of the destination, with emotional UGC having a greater influence.

A World Natural Heritage Site, Jiuzhaigou, is the first nature reserve in China whose primary purpose is to protect natural scenery. On August 8, 2017, a Ms 7.0 earthquake caused many unstable slopes in Jiuzhaigou, Sichuan Province, China. In the extreme storm conditions that follow, the unstable slopes tend to develop into potential landslides, which can cause many casualties and property losses in scenic areas. Sentinel-1A ascending orbit data were obtained in this paper to establish a SAR database. The large-scale deformation rate map of the study area was obtained using a small baseline set InSAR technology. The potential landslides in the deformation area are preliminarily confirmed with remote sensing interpretation. The field verification is further carried out by studying the deformation information of the characteristic points on the potential landslides. The results show that 13 deformation zones were preliminarily identified, and three typical deformation zones were selected for coupling verification and identified as potential landslides. At the same time, further analysis shows that the four potential landslides have been in continuous linear deformation for a long time since the earthquake, posing a severe threat to the safety of local people's lives and property. The research results provide a reference for the early identification and warning of potential landslides in earthquake-prone regions. [ABSTRACT FROM AUTHOR]

The emergence of Augmented Reality (AR) enriched and further enhanced the tourism experience. Drawn upon presence theory and a postmodernist perspective, this study rethinks the impact of postmodern authenticity on two different types of presences (Sense of Presence and Telepresence) and hence on visitor satisfaction and travel intention, by focusing on AR-based World Cultural Heritage Site – Mount Tai, China. Data were collected from 225 respondents visiting AR-based Mount Tai. Results demonstrated that postmodern authenticity positively predicts presences, satisfaction, and travel intention, and Postmodern authenticity has a more substantial effect on the Sense of Presence. Moreover, both types of presence positively predict satisfaction, hence travel intention while Sense of Presence has a stronger effect. Theoretical and managerial implications are presented.

Linear cultural heritage (LCH) is a precious treasure of human beings, but its spatial distribution and development modes in the context of tourism value are not clear. This study constructs the resource (R) –natural environment (N) –industrial economy (I) evaluation system through the Delphi method, analytical hierarchy process and entropy method to examine tourism value from the perspective of the whole heritage. This system is verified to the case of a World Heritage Site, the 1800 km-long Beijing–Hangzhou Grand Canal in China. Combined with the situation of 22 cities along the canal, the standard values of each evaluation variable are determined. Besides total tourism value, R–N–I coordination is also calculated through a three-dimensional model. They are regarded as a classification basis in the grouping analysis method. According to the results, a resource is the most important factor, while natural environment and industrial economy are external supports for LCH tourism. Tourism value along Beijing–Hangzhou Grand Canal is divided into 'high-value imbalance type', 'key breakthrough type', 'comprehensive strengthening type' and 'low-value restriction type'. The findings offer theoretical construct and policy recommendations for the development and sustainability of LCH tourism. [ABSTRACT FROM AUTHOR]

Junjie Su's book, "Intangible Cultural Heritage and Tourism in China: A Critical Approach," examines the recognition and production of intangible cultural heritage (ICH) in the context of tourism development in China, with a focus on the case study of Lijiang. The book analyzes various perspectives, including those of government officials, experts, and local practitioners, to understand the complex meanings of ICH. It also explores the tensions between heritage preservation and tourism commodification. While the book provides valuable empirical data, it could benefit from updates on the impact of the COVID-19 pandemic and a stronger theoretical framework. Overall, it contributes to the understanding of China's cultural transformation and the politicization of cultural heritage. [Extracted from the article]

Over the past century, lake degradation has increased around the world. Jiuzhaigou World Natural Heritage Site in southwestern China has been experiencing water nutrient enrichment, accelerated swamping, and algal biomass increases. These problems are likely associated with enhanced local anthropogenic activities over the past decades. In this study, radioactivities of 137Cs and 210Pb, diatoms, and nutrient accumulation rates in a lake sediment core from Tiger Lake in Jiuzhaigou World Natural Heritage Site were used as proxies to reconstruct a > 100-year record of environmental change to understand the extent and temporal variability of anthropogenic effects on lake water nutrients. Diatom communities reveal four distinct phases, relating to documented local human activities including (a) Primitive agriculture from 1871 to the mid-1930s, (b) Opium cultivation—logging from the mid-1930s to the mid-1970s, (c) Large-scale logging—the beginning of tourism from the mid-1970s to the early 1990s, and (d) Tourism development from the early 1990s to 2013. Nutrients in the lake (including total organic carbon, total nitrogen, and total phosphorus) steadily increased from 1871 until the late 1990s, declined from the late 1990s to the mid-2000s, and increased rapidly after the mid-2000s. Our data suggest that (a) Opium cultivation, deforestation, and tourism development led to the increase of lake nutrients and primary productivity, (b) Ecological protection measures taken from 1999 to 2004 effectively controlled water pollution, and (c) Post-2005 intensification of tourism further accelerated water quality deterioration. Additional monitoring and mitigation strategies are needed to further reduce nutrient input. Global studies suggest that while water quality of lakes in protected area is better than that of other lakes, care is still required to ensure that tourism activities do not inadvertently increase lake water nutrients.

Taking Yancheng coastal wetland of China as the case, and using remote sensing images in 1997, 2007 and 2017 as the data sources, the spatial-temporal changes characteristics of landscape elasticity (LE) were analyzed from three dimensions of ecosystem service value (ESV), ecological vulnerability (EV) and human disturbance (H). From 1997 to 2017, Yancheng coastal wetland landscape structure showed a trend of increasing proportion of aquaculture ponds and construction land area, while decreasing proportion of natural wetland area The total ESV decreased first and then increased, the average ESV per unit area in 1997, 2007 and 2017 were 5.23 × 104 USD·hm-2, 4.28 × 104 USD·hm-2, 5.95 × 104 USD·hm-2, respectively. The average EV decreased from 0.182 to 0.170 during 1997 to 2017. The average H increased from 0.175 to 0.198 during 1997 to 2017. In terms of spatial differentiation, the ESV, the EV and the H all showed the characteristics of land-sea differences. The average LE increased from 0.263 in 1997 to 0.914 in 2017, showing a downward trend from land to sea and the southern region was better than the northern region. This study can provide reference for the sustainable construction and management in Yancheng Coastal wetland World Natural Heritage Site. [ABSTRACT FROM AUTHOR]

Ecological risk assessment (ERA) is an indispensable method for systematic monitoring of World Heritage Sites (WHSs) exposed to various anthropogenic factors and natural disasters. Remote sensing (RS) and geographical information systems (GIS) can eliminate many limitations in traditional ERA methods. In this study, changes in ecological risk at Huangshan Mountain, the first mixed WHS in China, over the period of 1984–2019 were explored using remote sensing images and products by considering both natural disasters and human disturbance. Results show that of the four land cover types in Huangshan Mountain, namely water, forest, building and farmland, the main land cover type is forest. During the 35 yr, lands categorised at low or relatively low ecological risk levels are dominant in Huangshan Mountain, with the lowest and highest ERIs (ecological risk index) in 1990 and 2010, respectively. The areas at the five ecological risk levels have declined as follows: relatively low > low > medium > relatively high > high. Changes in ecological risks are closely related to changes in land cover and natural disasters. Even though major natural disasters may affect the ecological risk level in the whole region, changes in land cover caused by human activities will shift the ecological risk level in some areas. Our attempts can be modified and applied to other sites, and offer policy implications for protection and preservation of WHSs. [ABSTRACT FROM AUTHOR]

The production of services and goods needs consumption of available material and energy. An economy often focuses on sources of high-quality material/energy first produced by nature for increasing growth. World heritages sites (WHSs) have become major tourist attractions that promote economic development for developing countries. The increased number of tourists has thus brought about threats to ecological environment. Scholars stress that it should be sustainable or "green growth" since it comes to economic growth currently. The aim of this research is to establish a sustainable development model for WHSs to empirically investigate the dilemma between economic development and ecological protection with particular emphasis on strategies that promote the sustainability. The study took China's 45 WHSs as samples and constructed a two-stage sustainable development model to analyze the trade-off between economic development and ecological protection. The dynamic network slacks-based measure was employed for dynamic performance evaluation for the period 2013-2019. The results suggest that a strong balance between economic development and ecological protection would be essential for sustainability. Spearman's rank correlation was also used to verify that there are no conflicts between the two processes. In addition, this study demonstrates that an effective government policy covering regulations of economic development and ecological protection can positively influence sustainable development. The governments are suggested to improve the section that the WHS performs inefficient. Involvement of balanceable sustainable development for WHSs needs necessary cooperation during concerned institutions, practitioners, and communities. The WHSs are recommended to receive strict standard of supervision, management, and control. [ABSTRACT FROM AUTHOR]

Kulangsu is a famous scenic area in China and a World Heritage Site. It is important to obtain knowledge with regard to the status of soundscape and landscape resources and their interrelationships in Kulangsu before it became a World Heritage. The objective of this study was to explore the spatial dependency of the soundscapes in Kulangsu, based on the spatiotemporal dynamics of soundscape and landscape perceptions, including perceived sound sources, soundscape quality, and landscape satisfaction degree, and the spatial landscape characteristics, including the distance to green spaces, normalized difference vegetation index, and landscape spatial patterns. The results showed that perception of soundscape and landscape were observed in significant spatiotemporal dynamics, and the dominance of biological sounds in all sampling periods and human sounds in the evening indicated that Kulangsu scenic area had a good natural environment and a developed night-time economy, respectively. The green spaces and commercial lands may contribute to both the soundscape pleasantness and eventfulness. Moreover, the soundscape quality was dependent on the sound dominant degree and landscape satisfaction degree but not on the landscape characteristics. The GWR model had better goodness of fit than the OLS model, and possible non-linear relationships were found between the soundscape pleasantness and the variables of perceived sound sources and landscape satisfaction degree. The GWR models with spatial stationarity were found to be more effective in understanding the spatial dependence of soundscapes. In particular, the data applied should ideally include a complete temporal dimension to obtain a relatively high fitting accuracy of the model. These findings can provide useful data support and references for future planning and design practices, and management strategies for the soundscape resources in scenic areas and World Heritage Sites.

This study complements the tourism literature by proposing an asymmetrical effect of the tourism-led growth hypothesis on the city-level economy using panel data from 331 cities in China from 2004 to 2015 (3,972 observations). The results, based on an augmented Solow model and the system-generalized method of moments (GMM), reveal that the impact of tourism on city-level economic growth is indeed asymmetric and heterogeneous, depending on the presence of top-level attractions (TL), which are proxied by the World Heritage Sites or AAAAA (5A) scenic spots. The dynamic panel threshold model's results also corroborate the asymmetric threshold effect of tourism on city-level economic growth. Tourism, in particular, has facilitated positive and significant economic growth in cities with TL but has had an uncertain and statistically insignificant impact on cities without it. The findings indicate that the validity of tourism-led growth depends on the availability and number of TL in each city, which serve as a moderator. As a result, we confirm tourism's asymmetric effect and spatial heterogeneity on urban economic growth. [ABSTRACT FROM AUTHOR]

To improve the efficiency and accuracy of digital protection of burial sites, the digital protection of burial sites was studied by the collaborative observation technology of LiDAR and unmanned aerial vehicle (UAV) mapping. Multi-feature constrained iterative global registration algorithm is used to realize fast registration of multi-site cloud, the Structure from motion (SFM)-based algorithm is used to generate dense point cloud from UAV image, and then the Iterative Closest Point(ICP) algorithm is used to realize the fusion of point cloud data on-site and image. According to the fused data, a variety of measurable results, such as high-precision burial model and contour map, are produced, and an orthophoto generation system is written independently, which can fully automatically generate high-precision orthophoto map and realize the digitalization of the burial sites. Taking the protection application of the burial site in Yaoheyuan, Ningxia, one of the top 10 archeological discoveries in China in 2017, with guaranteed data accuracy and integrity, the surveying and mapping data of the tomb site was obtained quickly. The global registration accuracy of the proposed algorithm is within 1 cm, and the registration efficiency was superior to the current mainstream open source algorithm, which verified the feasibility and efficiency of this method. It provides an effective scheme for the digital protection of burial cultural heritage, and is also suitable for the digital protection of other heritage sites in the World Heritage List such as Panlongcheng Site and Sanxingdui.

Coastal wetlands are large reservoirs of soil carbon (C) and have been invaded globally by the exotic species Spartina alterniflora. However, the effects of these invasions on soil C content remain unclear.We performed a meta‐analysis of 2479 soil organic C (SOC) content observations collected from 91 field studies conducted in coastal China, the world's largest introduced range for S. alterniflora.Spartina alterniflora invasions had no significant effect on the SOC content in vegetated native wetlands in coastal China. S. alterniflora increased the SOC content in the top 30 cm of salt marshes after invading only one of the nine marsh types, which was dominated by a dwarf succulent species, Suaeda salsa in the northern subtropics and decreased the SOC content in the top 60 cm of mangroves dominated by Kandelia obovata and mixed communities after invasion in the southern subtropics. S. alterniflora invasions did not significantly affect the SOC content in the other salt marsh or mangrove ecosystems. Moreover, the SOC content in S. alterniflora‐invaded ecosystems increased only on a decadal scale and then decreased, rather than increasing monotonically.Synthesis and applications. Our findings reveal that the SOC content of S. alterniflora‐invaded ecosystems is similar to or lower than that of most native ecosystems. As soil bulk density is often reduced by S. alterniflora invasions, the C storage capabilities of vegetated native ecosystems might be substantially reduced after S. alterniflora invasions. Moreover, the SOC content in these invaded ecosystems gradually decreased after long‐term S. alterniflora invasions (>20 years). Therefore, the displacement of native salt marsh or mangrove species by S. alterniflora may not be considered a natural climate solution to increase the C sink in coastal China. Future efforts are required to control S. alterniflora preferentially in coastal wetlands where S. alterniflora invasions do not increase the SOC content, and to conserve and restore native coastal wetlands, which are the core areas of the World Natural Heritage site serving as China's Migratory Bird Sanctuaries that have been severely threatened by S. alterniflora invasions, to increase ecological integrity and C sinks and to mitigate climate change.

The assessment of public participation is one of the most fundamental components of holistic and sustainable cultural heritage management. Since the beginning of 2020, the COVID-19 pandemic became a catalyst for the transformation of participatory tools. Collaboration with stakeholders moved online due to the strict restrictions preventing on-site activities. This phenomenon provided an opportunity to formulate more comprehensive and reasonable urban heritage protection strategies. However, very few publications mentioned how social networking sites' data could support humanity-centred heritage management and participatory evaluation. Taking five World Cultural Heritage Sites as research samples, the study provides a methodology to evaluate online participatory practices in China through Weibo, a Chinese-originated social media platform. The data obtained were analysed from three perspectives: the users' information, the content of texts, and the attached images. As shown in the results section, individuals' information is described by gender, geo-location, celebrities, and Key Opinion Leaders. To a greater extent, participatory behaviour emerges at the relatively primary levels, that being "informing and consulting". According to the label detection of Google Vision, residents paid more attention to buildings, facades, and temples in the cultural heritage sites. The research concludes that using social media platforms to unveil interplays between digital and physical heritage conservation is feasible and should be widely encouraged. [ABSTRACT FROM AUTHOR]

The authenticity of heritage tourism is an important factor for attracting tourists. Research has shown that authenticity is related to revisit intention. However, little attention has been paid to the impact of heritage tourism authenticity on revisit intention. Drawing on cognitive appraisal theory, we constructed a model of the mechanism underlying this relationship. Questionnaires were distributed at one world heritage site (the Dujiangyan irrigation system) in China, and data from 596 valid cases were collected. Using structural equation modeling, the results showed that authenticity, directly and indirectly, affects tourists' revisit intention via memorable tourism experiences and place attachment. The current paper enriches existing literature on the relationship between authenticity and revisit intention and provides a theoretical basis for promoting authenticity and revisit intention in heritage tourism.
