Drought, characterized by frequent occurrences, an extended duration, and a wide range of destruction, has become one of the natural disasters posing a significant threat to both socioeconomic progress and agricultural livelihoods. Large-scale geographical environments often exhibit obvious spatial heterogeneity, leading to significant spatial differences in drought's development and outcomes. However, traditional drought monitoring models have not taken into account the impact of regional spatial heterogeneity on drought, resulting in evaluation results that do not match the actual situation. In response to the above-mentioned issues, this study proposes the establishment of ecological–geographic zoning to adapt to the spatially stratified heterogeneous characteristics of large-scale drought monitoring. First, based on the principles of ecological and geographical zoning, an appropriate index system was selected to carry out ecological and geographical zoning for Yunnan Province. Second, based on the zoning results and using data from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and the Tropical Rainfall Measuring Mission (TRMM) 3B43, the vegetation condition index (VCI), the temperature condition index (TCI), the precipitation condition index (TRCI), and three topographic factors including the digital elevation model (DEM), slope (SLOPE), and aspect (ASPECT) were selected as model parameters. Multiple linear regression models were then used to establish integrated drought monitoring frameworks at different eco–geographical zoning scales. Finally, the standardized precipitation evapotranspiration index (SPEI) was used to evaluate the monitoring effects of the model, and the spatiotemporal variation patterns and characteristics of winter and spring droughts in Yunnan Province from 2008–2019 were further analyzed. The results show that (1) compared to the traditional non-zonal models, the drought monitoring model constructed based on ecological–geographic zoning has a higher correlation and greater accuracy with the SPEI and (2) Yunnan Province experiences periodic and seasonal drought patterns, with spring being the peak period of drought occurrence and moderate drought and light drought being the main types of drought in Yunnan Province. Therefore, we believe that ecological–geographic zoning can better adapt to geographical spatial heterogeneity characteristics, and the zonal drought monitoring model constructed can more effectively identify the actual occurrence of drought in large regions. This research finding can provide reference for the formulation of drought response policies in large-scale regions. [ABSTRACT FROM AUTHOR]

An ascomycetous fungus was collected and isolated from dead leaves of Livistona chinensis in Lincang City, Yunnan Province, China, and morphology and multi-gene phylogenetic analyses of LSU, ITS, Actin, and β-tub were carried out to identify it. The morphology and multigene phylogeny revealed that this fungus is a distinct species of Thyridium. Therefore, this fungus is described and introduced as Thyridium livistonae sp. nov. In addition, two new combinations T. hipposidericola and T. xishuangbannaense are proposed based on morphology and phylogeny for Phialemoniopsis hipposidericola Karun., Tibpromma & X.F. Liu and P. xishuangbannaensis Karun., Tibpromma & X.F. Liu respectively. A detailed description, illustrations, and phylogenetic results are provided for the new species and two new combinations.

Objective To understand the current the status of sexual knowledge, attitude and behavior in university students from three non-medical colleges and universities in Yunnan Province. Methods From September, 2022 to June, 2023, 1 170 college students from three non-medical universities in Yunnan Province were selected by multistage stratified cluster random sampling methods to conduct a questionnaire survey on their sexual knowledge, attitudes and behaviors, and descriptive methods were used to analyze their sexual knowledge, attitudes and behaviors. Results The awareness rate of emergency contraception within 72 hours was 22.2%, and the awareness rate of condoms for disease prevention and contraception was 65.6%. The awareness rates of PrEP and PEP were 49.2% and 39.3%, and the overall awareness rate of AIDS prevention knowledge was less than 90.0%. The overall awareness rate of sexual health and AIDS prevention knowledge among girls was higher than boys (P < 0.05) . 72.8% of the sampled population did not oppose premarital sex, and boys have a more open attitude towards sex than girls ( P < 0.05) . 18.9% of respondents have had sexual activity. Among those with a history of sexual behavior, 60.5% can correctly use condoms consistently, and 35.1% have more than two sexual partners. The sexual behavior of boys is higher than that of girls ( P < 0.05) . Among college students, 42.6% received sex education in junior high school, and 41.4% obtained sexual knowledge through the Internet. Conclusion College students lack sexual health knowledge, and their sexual attitudes and behaviors are relatively open. It is imperative for non-medical colleges in Yunnan Province to carry out comprehensive sex education. [ABSTRACT FROM AUTHOR]

Objective To analyze the surveillance data of scarlet fever in Yunnan Province from 2010 to 2022, in order to understand its incidence level and epidemiological characteristics, and to provide a scientific basis for further prevention and control. Methods The scarlet fever data from 2010 to 2022 in Yunnan Province were obtained from the "China Disease Prevention and Control Information System". The spatial distribution was described, and seasonal trends were analyzed using seasonal indices. A total of 92 scarlet fever cases reported by 22 medical institutions in the province were randomly selected for verification of diagnostic accuracy. Results From 2010 to 2022, a total of 21 081 cases of scarlet fever were reported in Yunnan Province, with only 5.25% confirmed cases. The average annual incidence rate was 3,44 per 100 000, with no reported deaths. There were two peaks in the incidence rate each year, in spring/summer and winter, accounting for 49,78% and 17.43% of the total annual cases, respectively. The highest incidence rates were observed in children under 10 years old, with an incidence rate of 23.75 per 100 000, and the incidence rate in boys was higher than that in girls. The cities and prefectures with the highest average annual incidence rates were Lijiang city (10.49 per 100 000), Yuxi city (7.67 per 100 000), Dali Prefecture (5.54 per 100 000), and Pu-er city (5.21 per 100 000). The areas with significant increases in incidence rates around 2020 were Diqing Prefecture, Nujiang Prefecture, Qujing city, and Wenshan Prefecture, and the specific counties with significant increases were Qiubei County in Wenshan Prefecture, Weixi County in Diqing Prefecture, Luoping County in Qujing city, and Lanping County in Nujiang Prefecture, Among the 92 scarlet fever cases reported by the 22 medical institutions from 2021 to 2022, the diagnostic accuracy was 56.52%. Conclusion From 2010 to 2022, the overall incidence of scarlet fever in Yunnan Province showed an increasing trend. It is recommended to implement comprehensive prevention measures focusing on health education in key epidemic areas such as Lijiang, Yuxi, and Dali, and to carry out pathogen surveillance. In areas with significant recent increases in incidence, such as Qiubei County in Wenshan Prefecture, Weixi County in Diqing Prefecture, and Lanping County in Nujiang Prefecture, it is recommended to conduct quality verification of case diagnosis to understand the true situation of scarlet fever incidence.

This study applied Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) multispectral data and ZY1-02D hyperspectral data to map the structural distribution and hydrothermal alteration in the polymetallic ore district in southern Shangri-La City, Yunnan Province, China. The study area hosts several polymetallic deposits, including the Mahuaping tungsten–beryllium deposit, which has significant mineral exploration potential. The deposit type is mainly magmatic–hydrothermal, with average grades of 0.41% WO3 and 0.22% BeO, and substantial reserves, prominently controlled by faults. Based on this, this study employed ASTER data for the visual interpretation of structures through false-color composites combined with DEM data. Additionally, ASTER and ZY1-02D data were processed using the principal component analysis and spectral angle mapper methods to extract anomalies related to tungsten mineralization such as carbonate alteration, sericitization, chloritization, and hematization of the hydrothermal origin. The results indicated that the structural trends in the study area predominantly align in north–south and northeast directions, with alteration anomalies concentrated in the central and fold areas. Our analysis of typical deposits revealed their close association with north–south faults and east–west joints, as well as the enrichment level of alteration anomalies, identifying five high-potential target areas for mineral exploration. Further evaluation involved field validation through the spectral scanning of samples, field verification, and a comparison with known lithology. These assessments confirmed that the spectral curves matched those in the USGS database, the structural interpretations aligned with the field observations (84% accuracy from 25 sampling points, with 21 matching extracted alteration types), and the alteration results corresponded well with the lithological units, indicating high accuracy in alteration extraction. Finally, a comparative discussion highlighted that the results derived from ZY1-02D data were more applicable to the local area. The outcomes of this study can support subsequent mineral exploration efforts, enhancing the sustainability of important mineral resources. [ABSTRACT FROM AUTHOR]

Drug crime is a serious global problem requiring attention. This study focuses on the spatial characteristics and factors influencing drug crimes at the provincial level. Understanding these factors is crucial to combating drug crime and maintaining social stability. In the past, most studies analyzed and discussed drug crimes at the macro and micro scales; however, research on the meso scale is still relatively lacking, and the special geographical location and complex socioeconomic conditions near the border of Myanmar in Yunnan Province had a high incidence of drug crimes, so it was still necessary to study drug crimes at the meso scale in Yunnan Province. This study considers drug crime cases from 129 counties and districts in Yunnan Province and employs Geographic Information System (GIS) statistical analysis, spatial autocorrelation analysis, and a spatial gravity model to examine the spatial difference patterns and spatial correlation network characteristics of drug crime in the province. Additionally, an indicator system for drug crime-influencing factors was constructed, which included economic level, income level, urbanization level, education level, floating population, impact of drug source areas, and terrain complexity. A regression analysis using a Spatial Durbin Model was conducted to analyze the relationship between these factors and drug crimes. First, the drug crime rate in Yunnan Province exhibits a notable spatial variation pattern, wherein clusters of high crime rates are primarily concentrated along the China-Myanmar border. Second, drug crimes in different districts and counties of Yunnan Province exhibit notable spatial correlation and agglomeration patterns on a global scale. Considering the spatial distribution, two main groups with strong spatial correlation networks were identified. The first group includes Kunming's central urban area and its surrounding districts and counties. The second group consists of districts and counties along the Yunnan border. This spatial distribution aligns with the cubic function curve depicting the relationship between distance from Myanmar and the density of drug crime rates. Third, among the influencing factors, the economic level, income level, urbanization level, and drug source area have a significant impact on the drug crime rate in Yunnan Province. Notably, factors related to the source of drugs had the most significant influence, displaying a significant negative correlation. The relationship between the distance from the China-Myanmar border (the source of drugs) and the drug crime rate follows an elongated "inverted S" shaped distribution curve. It demonstrated a significant initial decrease, followed by a slight increase and then a subsequent downward trend. Additionally, the economic level has a significant negative impact on the variation in drug crimes in Yunnan Province, whereas income and urbanization levels have a positive impact. In conclusion, this study focused on the research area of Yunnan Province, which is known for its high incidence of drug crimes, making it a suitable and significant region for this study. It conducted a quantitative analysis of the spatial differentiation characteristics and influencing factors of drug crimes in the Yunnan Province at a provincial mesoscale. Analyzing the exploration of the direction of these influencing factors contributes to the advancement of research on criminal geography.

ObjectiveTo analyze the whole-genome characteristics of four coxsackievirus B5 (CVB5) strains isolated in Yunnan province, China in 2022. MethodsPrimers were designed to amplify and sequence the whole genome of CVB5 isolates. The whole genome was amplified in segments, and sequenced using the "primer walking" method. Sequence splicing and assembly were performed. Genetic characteristics of the CVB5 strains were analyzed using software such as MEGA 7.0, Simplot 3.5.1, and DNAStar 7.1. ResultsBased on VP1 and whole-genome phylogenetic analysis, all four CVB5 isolates belonged to genotype C. Compared with the prototype strain, multiple amino acid mutations occurred in the VP1 region of the four strains. Phylogenetic analysis of P1, P2, and P3 regions and Simplot recombination analysis showed that the CVB5 isolates in this study may have undergone recombination with multiple enterovirus B strains. ConclusionThe four CVB5 strains isolated from clinical samples of hand, foot and mouth disease (HFMD) patients in Kunming, Yunnan province in 2022 all belonged to genotype C.

Since the early 1980s, China's southwestern borderland area of Xishuangbanna in Yunnan Province has witnessed an astounding rejuvenation of Theravada Buddhism among the Dai-Lue and Bulang ethnic groups. This has occurred in the larger context of a general revitalisation of religion throughout China and specifically Theravada Buddhist revivalism in the upper-Mekong region. The emigration of the Dai-Lue and Bulang peoples in Xishuangbanna from the 1950s through the 1970s and their reconnection from the 1980s through the 2010s reforged a sense of trans-regional belonging across this area of China, Shan State in Myanmar, and northern Thailand. This sense of belonging re-established religious connections in the borderlands. This article argues that trans-regionalisation in the upper-Mekong region and the revival of Buddhist traditions in Xishuangbanna were the result of a synergistic interaction. Theravada Buddhism was rebuilt through the cooperation between cross-border monks and laypeople. Monks of the Yuan Buddhist tradition facilitated the rebuilding of Buddhism in Xishuangbanna amid the social milieu of religious revivalism in China. Moreover, this article explicitly analyses the indispensable role lay devotees played in rebuilding their Buddhist tradition by working within the local temple-village structures.

ObjectiveTo understand the prevalence level and trend of hepatitis C virus (HCV) among 11 specific populations in Yunnan province, and to provide evidence for formulating and evaluating the effectiveness of prevention and control measures. MethodsThe annual report data from 2013 to 2022 on comprehensive prevention and control of hepatitis C were collected from all medical institutions in 16 prefectures/municipalities in Yunnan province and were analyzed using R software and the Cochran-Armitage trend test was used to assess the changing trends in HCV antibody (anti-HCV) positivity rates among different population groups and for different regions. ResultsOf a total of 64 879 772 person-times of anti-HCV detection performed in medical institutions during the period, 392 971 (0.61%) were anti-HCV positive, and the annual anti-HCV positive rates ranged from 0.49% (45 069/9 286 175) to 0.83% (20 819/2 494 869) during the period, with a decreasing trend (Z = – 100.05, P < 0.05). The top three population groups with the highest anti-HCV positive rate were drug users (27.46%, 52 508/191 184), detainees (3.31%, 3 183/96 038), and female sex workers (0.92%, 1 152/125 832). The anti-HCV positive rate showed a decreasing trend in all population groups, including preoperative patients, blood transfusion recipients, other medical clients, pregnant women, blood donors, drug users, female sex workers, detainees, and others (all P < 0.05), except for premarital checkups and men who have sex with men, whose anti-HCV positive rates showed an increasing trend (Z = 2.9252, P < 0.05; Z = 7.0807, P < 0.05). The top three regions with the highest anti-HCV positive rate were Dehong prefecture, Baoshan municipality, Honghe prefecture and Kunming municipality. The anti-HCV positive rate showed a decreasing trend in all prefectures/municipalities of the province during the period (all P < 0.05), except for in Diqing and Nujiang prefectures and Zhaotong municipality, whose anti-HCV positive rate showed an increasing trend (Z = 3.518, P < 0.05; Z = 7.2602, P < 0.05; Z = 4.5373, P < 0.05). ConclusionThe prevalence of anti-HCV positive in Yunnan province from 2013 to 2022 was mainly among key populations such as drug users, detainees, and female sex workers, with regions with higher positive rate including Dehong and Honghe prefectures, and Baoshan and Kunming municipalities, where the prevalence of former drug abuse was also higher.

ObjectiveTo analyze the changes in the time intervals between diagnosis and treatment and the influencing factors of diagnosis and treatment delay among rifampicin-resistant tuberculosis (RR-TB) patients from 2016 to 2021 in Yunnan province, to provide a reference for reducing the occurrence of diagnosis and treatment delay in patients. MethodsData of 2 189 RR-TB patients registered in Yunnan province from 2016 to 2021 were extracted from the Tuberculosis Management Information System (TMIS) – a subsystem of the China Disease Prevention and Control Information System – to analyze the time intervals between symptom onset and diagnosis and that between diagnosis and treatment for the patients with different demographic and other characteristics. The time intervals were described in median and percentile 25th/75th (M, P25/P75) days, and multivariate binary logistic regression was used to analyze factors influencing delays in diagnosis and treatment of RR-TB patients. ResultsFor all patients, the median number of days from symptom onset to confirmed diagnosis of RR-TB increased from 50 in 2016 to 109 in 2018, but then decreased annually to 42 in 2021, with a trend of first increasing and then decreasing. The RR-TB patients who underwent conventional drug susceptibility testing and received initial diagnosis at a prefectural or municipal-level medical institution were more likely to have delayed diagnosis, with the odd ratio (OR) and 95% confidence interval (95%CI) of 5.193 (3.750 – 7.193) and 1.449 (1.199 – 1.752), respectively. The median number of days from diagnosis to treatment for the 1 488 RR-TB patients being treated increased slightly from one day in 2016 to 11 days in 2021. The RR-TB patients with the following characteristics were more likely to have treatment delays: being male (OR = 1.309, 95%CI: 1.063 – 1.612), being a farmer (OR = 1.317, 95%CI: 1.022 – 1.698), and being a permanent resident (OR = 4.016, 95%CI: 3.220 – 5.008) ; whereas RR-TB patients of younger age were less likely to have treatment delay, with the OR (95%CI) of 0.676 (0.487 – 0.938), 0.687 (0.494 – 0.954), and 0.663 (0.489 – 0.901) for the patients aged 25 – 34, 35 – 44, and 45 – 55 years respectively, compared with those aged ≥ 65 years. ConclusionDuring 2016 – 2021, the time interval between symptom onset and diagnosis was significantly shortened and the interval between diagnosis and treatment was relatively short for RR-TB patients in Yunnan province but attention still needs to be paid to patients at high risk of delayed diagnosis and treatment.

Background Chronic diseases have become a major public health problem affecting the health of the population, and the number of patients with chronic diseases in China continues to increase, as well as the increasing number of deaths due to chronic disease by year, and the increasing burden of disease on patients gradually. Understanding the changes in the burden of chronic diseases is of great importance for the prevention and control of chronic diseases. However, there is a lack of research on the changes in the burden of common chronic diseases in rural Yunnan Province. Objective To examine the changes in the disease burden of five common chronic diseases [hypertension, coronary heart disease (CHD), stroke, asthma, and chronic obstructive pulmonary disease (COPD) ] among rural residents in Yunnan Province in 2011 and 2021. Methods A repeated cross-sectional design was used to select 8 400 and 7 700 rural residents aged≥35 years in Yunnan Province using multistage stratified random sampling method in 2011 and 2021 as the research subjects, respectively. Data were collected from on-site questionnaires and physical examinations of study participants, as well as data on the causes of death of five common chronic diseases. Principal component analysis was used to construct a socioeconomic position (SEP) indicator by selecting three variables including education level, annual household income per capita and accessibility to medical services, the coefficients of the variables were used to calculate the SEP composite score, and the SEP was classified into four grades of low, medium-low, medium-high and high based on the quartiles of the SEP composite score. Disability-adjusted life year (DALY) was used to measure the magnitude of the disease burden for five chronic diseases. Results Compared with 2011, the overall prevalence of hypertension (25.14% vs. 41.57%), stroke (1.03% vs. 2.52%), and COPD (9.23% vs. 12.60%) in rural Yunnan Province in 2021 increased (P0.05), while an increase was found in the prevalence of CHD among males and those with high SEP grade, and in the prevalence of asthma among males and those with medium-high SEP grade (P

From 2010 to 2020, the main counties (cities and districts) with fruit forest pruning and fruit cultivation (citrus, pomegranate, apple, pear and grapes) were studied as the research objects, based on the fruit forest pruning coefficient and the discount coal coefficient, the pruning resources of fruit forests in Yunnan Province were estimated, the biomass fuel potential was estimated, and the temporal and spatial distribution characteristics were analyzed. The results showed that from 2010 to 2020, the total amount of pruning resources in fruit forests in Yunnan Province showed an upward trend, and the average annual pruning amount of shoots was 1,522,700 tons. The resources of fruit forest pruning were significantly different between different regions. In 2020, the resources of fruit forest pruning in Yunnan Province were 2,617,500 tons, including 6 counties with more than 100,000 tons, 8 counties with 50,000 tons to 100,000 tons, and 31 counties with less than 50,000 tons. The annual average amount of shoots converted into pellet fuel into standard coal was 918,000 tons, and the average annual amount of standard coal converted into natural gas and power generation was 690 million m³ and 7 472 million kWh, respectively, and the potential annual value generated was 4 184 million yuan. Yunnan Province has great potential for energy conversion of fruit forest pruning branches, excellent resource endowment conditions for the development of biomass fuel, and has the resource base for the industrialization of biomass pellet fuel.

Quickly and accurately obtaining land use information can provide a reference for urban development and ecological environment protection. This study classifies land use types in Yunnan Province based on multi-temporal Landsat image dense time stacking and random forest algorithm on the Google Earth Engine （GEE） platform, analyzes the spatiotemporal change trends of LULC in Yunnan Province, and uses geodetectors to quantitatively evaluate key drivers factor. The results show that, 1） the average overall accuracy and Kappa coefficient of LULC classification in this study are 88. 64% and 86. 01%, respectively, which is highly accurate and meets the data usage requirements. 2） The land types in Yunnan Province are mainly forest land, cultivated land, grassland, and sparse shrub grass mixed land, accounting for 97. 91%-98. 38%. Land use transfer mainly involves the conversion of forest land and cultivated land, and the conversion of grassland and sparse shrub grass mixed land into cultivated land. 3） The land use intensity in central and eastern Yunnan in Yunnan Province is generally higher than that in other regions, while the land use intensity in northwest and southwestern Yunnan is lower. 4） There are significant differences in the influence of different driving factors on LULC. Vegeta‐ tion type, average annual temperature and soil type have a relatively small impact on LULC changes. Elevation, slope, aspect, aver‐ age annual precipitation, population density, GDP and population urbanization rate, etc., generally have a high impact on LULC changes, Among them, GDP, population density, and population urbanization rate have a higher impact on LULC changes. The re‐ search results can provide data basis and support for subsequent ecological and environmental protection policy formulation and re‐ gional sustainable development in Yunnan Province.

The present world pattern has undergone major changes, the trend of world multi-polarization is constantly emerging, and peace and development remain the main themes of today's society. The formal signing and implementation of the Regional Comprehensive Economic Partnership (RCEP) is important for meeting the needs of peace and development of many countries and regions. China is in a new era of reform and opening-up, and the RCEP content is in line with China's concept of pursuing a path of rejuvenation. Based on the locations of important borders, Yunnan Province has become one of the key places for China's opening-up and development regarding Southeast Asia and South Asia, and the high-quality development of its tourism service trade is of great significance. This study first used the grounded theory analysis method to organize, analyze and process the records of international conferences and government press conferences held in Yunnan Province, as well as important related issues since the signing of RCEP. Then, the social network analysis method was used to analyze the social recognition degree of RCEP in promoting the high-quality development of the tourism service trade in Yunnan Province from the perspectives of different levels and group consensus. The results show that cooperation is the key macro driving force for RCEP in promoting the high-quality development of the tourism service trade in Yunnan Province. Regarding the opportunities and environment of the transportation dividend, policy dividend and investment dividend, port construction, border township construction and exhibition-related construction are important cooperation contents, so they are conducive to the recovery of the tourism industry in a broader development space. Competition can improve the driving force of RCEP in promoting the high-quality development of the tourism service trade in Yunnan Province at the micro level, and has more practical significance. For example, RCEP can better rely on its own geographical advantages and international market competitiveness, optimize the use of resources inside and outside ports, and use high-tech products to form a more green, ecological, organic and sustainable development. In different levels of social identity, RCEP's power of cooperation is more strongly recognized, while the power of competition is less recognized. However, from the perspective of grouping the various groups, RCEP's powers of cooperation and competition are jointly recognized by the other groups, indicating that cooperation and competition are necessary for the realization of RCEP's power. The results of this study provide a certain reference for understanding the dynamics of RCEP in more detail from more angles and for the local implementation of RCEP rules and measures.

Objective Investigate the current status of implementation of three mandatory industry standards (WS310-2016) for sterilization supply centers (CSSDs) in medical institutions at all levels in Yunnan Province compare the development gap of CSSDs outside the province. and investigate the development needs. Methods Based on the requirements of WS310-2016 and the current stage of CSSD development status of medical institutions at all levels in Yunnan Province, a questionnaire was designed. 46 refined indicators were identified.. and the current status of the implementation of WS310-2016 in medical institutions at all levels in- side and outside the province was investigated and analyzed in September 2022 and December 2023-respectively through online surveys. Results Among the 382 medical institutions were surveyed. 195 within Yunnan Province and 187 outside the province. There was no significant difference in the percentage of medical institutions at all levels within and outside Yunnan Province (P>0.05). of which 23(11.8%) were able to fully implement the industry standards within the province and 29 (15.5%) outside the province. The human resources. equipment setup and configuration, device management and quality monitoring of CSSDs in Yunnan Province lagged behind those in developed regions outside the province to varying degrees, and the difference were statistically significant (P<0.05). Conclusion There is a certain gap between the development of CSSD in Yunnan Province and outside the province and resource allocation and other constraints on the implementation of standards, the formation of a team of CSSD experts, the establishment of provincial CSSD quality control center and the construction of a platform for academic exchanges. in order to accelerate the process of standardization. normalization and homogenization of CSSD in Yunnan Province.

In addressing the issue of accuracy in large-scale spatial land use type classification based on remote sensing, precise and efficient land use classification extraction methods and land classification models suitable for diverse high-altitude mountainous terrains were compared and proposed. The random forest ( RF) and support vector machine (SVM) algorithms were employed to classify land use in Yunnan Province. Accuracy validation was carried out by visually interpreting and randomly sampling 1525 sample points. The results indicate that the application of RF and SVM classification algorithms both yield land use classification accuracy of over 80% in Yunnan Province. Cultivated land in Yunnan Province shows a trend of initial increase and subsequent decrease from 2019 to 2021. Using RF and SVM, overall accuracy and Kappa coefficients are effective for comparative analysis of land use classification. The RF algorithm demonstrates higher accuracy in identifying land features within the study area compared to SVM, making it more suitable for land use classification research in Yunnan Province's high-altitude mountainous terrain.

Introduction: In the era of the Internet, online digital traces have become a new way to study the online attention of scenic spots and tourists’ purchase behavior. The public’s information search on major search platforms is a series of manifestations of potential tourists’ attention and interest in scenic spots, but there are few studies on how attention, interest and information search affect potential tourists to generate real purchase behavior. Method: This paper selects four dimensions of short video platform, travel website, search engine and social media to comprehensively measure the online attention of high-quality scenic spots in Yunnan Province, and then establishes a gray association analytic hierarchy process based on the relevant variables of the AISAS model to empirically analyze the primary and secondary factors affecting tourists’ purchase behavior. Results: (1) From the perspective of the online attention of scenic spots on different platforms, the intensity of the public’s scenic spots online attention on the four types of media platforms is in the order of travel websites, search engines, short videos and social media (2) From the perspective of spatial distribution characteristics, the online attention of high-quality scenic spots in Yunnan Province is unevenly distributed, that is, there is a big difference between the attention of higher star scenic spots and their star rating and popularity, while the attention of low-star scenic spots is not much different from their star rating and popularity (3) From the perspective of spatial agglomeration characteristics, the comprehensive online attention of high-quality scenic spots in Yunnan Province presents the spatial agglomeration characteristics of “the multi-core linkage of high-density in the east and north, and sub-high-density in the south” (4) The factors influencing the purchase behavior of potential tourists are sharing experience, attracting attention, generating interest and searching information. Discussion: By exploring the formation mechanism of high-quality scenic spots online attention in Yunnan Province and the mechanism of its spatial differentiation, this study not only enriches the logical chain of “tourism information source → potential tourists → demand driven → tourism information search → travel preference → destination selection → purchase decision → travel experience → real tourists → feelings after traveling → focus on feedback → tourism information source,” but also broadens the application scenarios and application boundaries of travel preference theory and AISAS behavior model to a certain extent.

The study area is located in the middle-southern part of Lincang granite in southwestern Yunnan. To verify the coexistence condition of non-ferrous and rare metals in the rare earth element (REE) orebody, 30 chemical samples are collected from the drilled orebody to analyze elements including W, Sn, Nb, Ta, Rb and Cs. The following methods and steps are adopted to study the migration and enrichment of ore-forming elements in granite : First, the analysis values of each element are arranged in order from large to small and divided into 6 groups, with 5 data in each group. Observation shows that, of the samples, 21 have no mineralization, 4 have Sn mineralization, 4 have Rb mineralization, and one has Sn and Rb mineralization. Then, among the unmineralized samples, the element contents (in mass fraction) of weathered crust are compared with those of unweathered rocks to quantitatively evaluate the migration and enrichment degree of elements during weathering. Compared with the bedrocks in the area, the contents of W, Sn, Nb and Ta have increased (showing enrichment), while the contents ofRb and Cs have decreased (showing migration). Finally, the average values of Sn and Rb mineralized samples are compared with those of non-mineralized samples to quantitatively evaluate the mineralization degree of rocks. According to the average value of mineralized samples, Sn mineralization is accompanied by weak W and Ta mineralization, Rb mineralization by obvious W, Ta and Cs mineralization, and Sn-Rb mineralization by obvious W, Ta and Cs mineralization.

Regional ecosystem service value (ESV) is significantly influenced by factors such as land use/cover change (LUCC). In this study, from the perspective of spatio-temporal heterogeneity, we constructed a dynamic and zonal equivalence table of ecosystem service values using the equivalence factor method and analyzed the spatio-temporal changes in ecosystem service values of different agricultural plantation regions of the karst mountainous areas of southwestern China (Yunnan Province, YP) in the years from 1990 to 2020. Also, the ESV of YP in 2030 was simulated using the Patch-generating Land Use Simulation (PLUS) model. The results showed the following: (1) land use/land cover (LULC) in YP from 1990 to 2020 was dominated by needle-leaved forestland, broadleaved forestland, grassland, and rainfed cropland. (2) The total ESV in YP fluctuated between CNY 876.74 and 1323.68 B from 1990 to 2020, expanding at a rate of 50.98%. The largest portion of the total ESV comes from climate regulation. The ESV increased from east to west, and the positive spatial correlation of the ESV gradually weakened. (3) The ESV in YP was projected to reach CNY 1320.70 B by 2030, representing a decrease of ~CNY 2.98 B since 2020. The results showed a decline in the ecological environment's quality in YP.

Three new wood-inhabiting fungal species, Lyomyces punctatomarginatus, L. lancangjiangensis and Mycobernardia yunnanensis, are proposed based on a combination of morphological features and molecular evidence. Lyomyces punctatomarginatus is characterized by a smooth hymenophore, a monomitic hyphal system with the generative hyphae having clamp connections, the presence of fusoid cystidia, and ellipsoid basidiospores (4–5.3 × 2.5–3 µm); L. lancangjiangensis is characterized by a monomitic hyphal system with clamped generative hyphae, fusiform and capitate cystidia, and ellipsoid basidiospores (4.5–5.8 × 2.8–4.5 µm). Mycobernardia yunnanensis is characterized by a monomitic hyphal system with clamped generative hyphae, and allantoid basidiospores (4.5–6.3 × 2–3 µm). Sequences of ITS and nLSU rDNA markers of the studied samples were generated and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogram inferred from the ITS dataset revealed that L. punctatomarginatus formed a monophyletic lineage and was grouped closely with L. crustosus, L. juniperi, L. niveus and L. ochraceoalbus. Additionally, L. lancangjiangensis grouped closely with L. albopulverulentus and L. bambusinus with strong supports. The phylogenetic tree inferred from the ITS + LSU rDNA sequences highlighted that the new species M. yunnanensis was sister to M. incrustans, the type species of the genus Mycobernardia within the family Corticiaceae.

The present study introduces a novel fungus, Cystoderma yongpingense, which was identified in the southwestern region of China. The new species is characterized by a pileus that ranges in color from light orange-red to orange-red; the pileus has a wrinkled surface and is accompanied by a persistent annulus that is membranous and floccose-scaly. Above the annulus, the color transitions from white to yellowish brown. This proposal is substantiated through analyses encompassing both morphological characteristics and phylogenetic relationships. The phylogenetic position of the newly discovered species has been further corroborated through comprehensive maximum likelihood and Bayesian sequence analyses of the ITS + nrLSU DNA regions. Additionally, the technical description of C. yongpingense is enhanced by detailed illustrations and comparative studies with species that are closely related. [ABSTRACT FROM AUTHOR]

Ecological vulnerability (EV) assessment is an important means of reflecting the evolutionary process of the local ecological environment, which is crucial for ecological security. The current EV assessment still faces challenges in comprehensively revealing its spatio-temporal change characteristics due to diversity, multi-scale complexity and non-linearity of ecosystems. In this study, we comprehensively revealed the spatio-temporal change features and driver mechanisms of EV in Yunnan Province (YP) using methods such as breaks for additive seasonal and trend (BFAST) and Geodetector. According to the findings, (1) the ecological vulnerability index (EVI) in YP decreased by 0.0265 on the raster scale between 2000 and 2018, and the ecological vulnerability level (EVL) was mainly dominated by level III. At the city scale, EVL in YP was dominated by level IV. At the basin scale, the average EV of the Jinsha River basin was much greater other basins. (2) The linear trend of EV in the YP mainly showed an insignificant decrease, mostly concentrated in the YP’s eastern region. The non-linear trend mainly showed a monotonous decrease, with the mutation time concentrated in 2009. The future persistence trend of EV under different coupling modes was dominated by anti-persistence decrease (Sen-MK + Hurst) and anti-persistence monotonous decrease (BFAST + Hurst), with an area percentage of 40.19 % and 25.13 %, respectively. (3) Gross primary productivity was the priority factor influencing YP’s EV (q = 0.4137). This study not only enriches the cases of EV assessment studies in the high mountain valley area but also bridges the gap of analysing the multi-spatial scale characteristics and change trends of regional EV.

Abstract The Dai people are primarily found in Yunnan Province, China, and have a long heritage there. The latest national census reports that Yunnan is home to 1,259,000 individuals of the Dai ethnic group. This study focuses on 3504 Dai settlements in Yunnan, identified through county records. Using the ArcGIS spatial analysis platform, we first evaluated their settlements’ spatial distribution patterns using metrics like the nearest neighbor index and geographic concentration index. Then, we applied geodetector to investigate the underlying mechanisms of their distribution. The results reveal that: (1) Dai settlements in Yunnan Province generally have a cohesive spatial distribution; at the provincial level, however, there is an uneven distribution pattern, with many densely populated areas and a pattern of “two cores, one belt, one area, and two points”; (2) The Dai settlements predominantly occupy the third gradient of the vertical zonation, with Dai gathering settlements primarily found in the Lancang, Ayeyarwaddy, and Red River basins. Conversely, Dai mixed settlements are mainly situated in the Lancang, Red, and Nu River basins; (3) Analysis via geodetector indicates that ethnocultural factors are the most significant in determining the spatial distribution of the Dai settlements, followed by socio-economic and natural factors; (4) The distribution of settlements is significantly influenced by the proportion of the Dai population within these settlements. Dai gathering settlements are typically located on flat slopes with elevations ranging from 500 to 1000 m and slopes of 0°–5°. Meanwhile, Dai mixed settlements are found on gentle slopes with elevations of 1000–2000 m and slopes of 5°–15°. The study reveals that the location of Dai settlements is strongly influenced by environmental considerations and has a significant explanation from similar origins.

Livelihood capital is the core element of sustainable livelihood development for rural households. Based on the survey data of 615 growers in the main rubber-producing areas of Hainan and Yunnan province, this paper constructs an evaluation system of rubber growers' livelihood capital within the sustainable livelihood analysis framework and calculates key indicators, such as farmers' livelihood capital index, livelihood activity diversity index, and household income diversity index. The multiple regression model and the mediating effect model are used to explore the influence mechanism of livelihood capital on the sustainable livelihood of rural households. The following three conclusions are drawn: (1) The accumulation of livelihood capital of rural households is conducive to enriching the structure of household livelihood activities and income sources, especially the accumulation of financial capital, which is more likely to improve the diversity of household livelihood activities. Regional differences exist in the impact of livelihood capital structures on rural household livelihood outcomes. Natural capital endowment has a significant effect on the income diversification level in Hainan, but there may be a "curse" effect in Yunnan. (2) Geographical characteristics, production decisions, and farming household characteristics significantly impact sustainable livelihoods. The altitude of the village and the distance from the county seat pose certain challenges for farmers in diversifying their livelihoods. Although the law of rubber tapping production may weaken farmers' production and business activities, it can better stabilize farmers' incomes owing to its strong flexibility in labor arrangements, which may be beneficial for diversifying livelihoods; however, it does not necessarily lead to diversified incomes. While the characteristics of poor households can help rural households gain policy support, building capacity is the key to achieving a sustainable livelihood. (3) There are intermediary effects of livelihood capital on livelihood activities and household income, but the mechanisms of action are different. For the diversity of farmers' livelihoods, 52.70% of the catalytic effect of livelihood capital is achieved by improving the ability to integrate livelihood capital. Optimizing household employment strategies contributed to the promotion of livelihood capital on the income diversification index, with a mediating effect of 30.52%. The main contribution of this study is to clarify how livelihood capital can achieve the goal of diversifying household livelihood activities and income by coordinating livelihood capacity and employment strategies. Therefore, to enhance the comprehensive livelihood capacity of rural households, the coordination capacity of livelihood capital, livelihood capacity building should be enhanced, and employment information channels should be expanded.

The 1:1 matched case-control study method was used, and single factor and conditional logistic regression were used for statistical analysis.Results: HPV types 16, 18 and 58 are mostly related with cervical cancer, the younger the age of the last pregnancy, the more times of pregnancy, childbirth and abortion, especially the younger the first marriage age of Bai and Dai, are the risk factors of cervical cancer; the infection of genital tract bacteria, mycoplasma and chlamydia is closely related to the incidence of cervical cancer in four ethnicities. Multifactorial analysis showed that demographic characteristics and environment/behavior were not included in the influencing factors of cervical cancer; among Han, Bai, Dai and Hani ethnic minorities, contraception (OR=0.29, OR=0.03, OR=0.09, OR=0.16, P< 0.05) was positive factor, HPV infection (OR=64.77, OR=128.71, OR=71.89, OR=40.07, P< 0.01) was a causative factor of cervical cancer.Conclusion: Risk of high parity with cervical cancer could be due to a complex interplay of factors, it is very important to formulate prevention strategies and measures in line with the cervical cancer of Han, Bai, Dai and Hani ethnic groups women in Yunnan Province.Keywords: cervical cancer, risk factors, case-control study, Han, Bai, Dai and Hani ethnic minorities, Yunnan Province

[Objective] To optimizing the pattern of territorial space development and coordinating the pattern of production-living-ecological space is the key task and fundamental way to achieve sustainable development in the future. [Methods] Based on the land use in Yunnan Province and combined with the natural and social development factors, the MOP-PLUS coupling model was used to simulate the changes of production-living-ecological space and its effects under three scenarios of economic priority, ecological priority and collaborative development in 2030. [Results] (1) Under the three scenarios, the economic benefit increased by 40.29%, 32.10% and 34.79%, the ecological benefit decreased by 0.89%, 0 (unchanged) and 0.06%, the average habitat quality decreased by 0.78%, 0.38% and 0.43%, and the average spatial conflict intensity increased by 2.79%, decreased by 1.21% and decreased by 2.32%. (2) Living space increased and ecological space decreased in the three scenarios. Production space only increased slightly in the economic priority scenario. In all cases, living space encroached on production space, and then production space plagued ecological space. The expansion of living space showed a trend of encroaching from the center to the periphery. (3) Habitat quality decreased to some extent under different development scenarios, and spatial conflicts could be balanced by optimizing spatial layout. Compared with other scenarios, the growth of economic benefits in the collaborative development scenario was moderate, the variation range of habitat quality was relatively balanced, and the intensity of spatial conflicts decreased the most, which was in line with the multiple goals of ecological protection, economic development and social progress. [Conclusion] The simulation-effect-optimization feedback regulation mechanism formed in this paper can be combined with different scales and objectives to carry out land use change simulation and effect analysis, and provide a basis for decision-making of territorial space allocation.

The spatial distribution characteristics of Buddhist monasteries in Yunnan Province, a typical sample area of Buddhist diversity, have not been studied. Therefore, in view of the situation and from the perspective of Buddhist geography, samples of Buddhist monasteries from 540 cultural relic protection units at all levels were selected to examine the spatial differentiation characteristics and influencing factors of Buddhist monasteries in Yunnan Province. GIS spatial analysis was combined with fieldwork methods. The following results were obtained: 1) Buddhist monasteries in the province are generally distributed in agglomerations, being concentrated in Dali, Honghe, and Kunming. The spatial distribution density is centered around three core areas, with other more discrete areas. The Chinese Buddhist monasteries are distributed in an inverted U-shaped band in the central part of the province, the Tibetan Buddhist monasteries are distributed in a "single core, many centers" pattern, and the Theravada Buddhist monasteries are distributed in a "two-side dense, middle-sparse" pattern. 2) Laterally, Buddhist monasteries are mainly distributed in the Jinsha, Lancang, and Pearl River basins, with considerable differences between sub-basins. Vertically, the monasteries have a "three-step" distribution characteristic, which corresponds to the vertical landforms. 3) The complex human-geographic environment of Yunnan is a key factor in the differentiation of Buddhist monasteries. The geographical structure is a fundamental force that determines the spatially differentiated character of Buddhist monasteries. The central geographical location connecting the four directions relies on the geographical environment to form a balance of distribution of the three types of Buddhist monasteries. Landforms and elevations combine to affect the distribution of ethnic groups with different livelihoods based on elevation and thus affect the distribution of Buddhist monasteries. The cultural structure has contributed to the formation of a pluralistic coexistence pattern in exchanges among various monasteries. The exchange through river basin corridors may have led to the development of Chinese Buddhist monasteries in the eastern Yunnan Plateau. Tibetan Buddhist monasteries form agglomeration centers in Diqing and Lijiang, in the northern part of the Longitudinal Ridge Valley, and southern Buddhist monasteries form major distribution areas in Dehong, Xishuangbanna, and other locations. The strip-shaped ethnic corridors formed by different ethnic groups based on geographical space have a high spatial fit with the distribution of Buddhist monasteries. The linear space, with the ancient road serving as an axis, has promoted interactive development of Buddhist monasteries of different sects. The mode of governance, influenced by institutional structure, has promoted changes in the distribution range of various monasteries in different historical periods, and changes in the relationships among the central government, local government, and Tusi system have altered agglomeration and distribution of Buddhist monasteries.

ABSTRACTRodents represent over 40% of known mammal species and are found in various terrestrial habitats. They are significant reservoirs for zoonotic viruses, including harmful pathogens such as arenaviruses and hantaviruses, yet knowledge of their hosts and distributions is limited. Therefore, characterizing the virome profile in these animals is invaluable for outbreak preparedness, especially in potential hotspots of mammal diversity. This study included 681 organs from 124 rodents and one Chinese tree shrew collected from Yunnan Province, China, during 2020-2021. Metagenomic analysis revealed unique features of mammalian viruses in rodent organs across habitats with varying human disturbances. R. tanezumi in locations with high anthropogenic disturbance exhibited the highest mammal viral diversity, with spleen and lung samples showing the highest diversities for these viruses at the organ level. Mammal viral diversity for both commensal and non-commensal rats was identified to positively correlate with landscape disturbance. Some virus families were associated with particular organs or host species, suggesting tropism for these pathogens. Notably, known and novel viral species that are likely to infect humans were identified. R. tanezumi was identified as a reservoir and carrier for various zoonotic viruses, including porcine bocavirus, hantavirus, cardiovirus, and lyssavirus. These findings highlight the influence of rodent community composition and anthropogenic activities on diverse virome profiles, with R. tanezumi as an important reservoir for zoonotic viruses.

High-quality development of protected areas requires scientific and orderly integration and system planning of protected areas at provincial and national levels. Based on the characteristics of quantity, area and spatial distribution of natural protected areas in Yunnan Prov- ince, the system planning strategy "complete system and scientific planning" is proposed. The quantitative and spatial distribution of natural protected areas at all levels in Yunnan Province and 16 prefectures and cities were sorted out, summarized and analyzed. From the phenome- non to the essence, the characteristics were condensed, and the planning strategy of system reconstruction was proposed. It is found that 11 types of natural protected areas in the province are managed by 7 competent departments, distributed in 16 cities of the province about 377, covering an area of about 55 277 km², accounting for about 14% of the province's land area. The number and area of various types of natural protected areas vary greatly, with forestry and housing administrative departments as the main management bodies, and the classification and classification standards are uncertain.

[Objective] The aims of this study are to reveal the changes of precipitation structure in Yunnan Province in the last 60 years, to strengthen the monitoring and early warning of precipitation in Yunnan Province, and to provide scientific reference basis for the risk assessment of water and drought disasters in Yunnan Province. [Methods] Based on daily precipitation observation data from 32 meteorological stations in Yunnan Province, two indicators of precipitation occurrence and precipitation contribution were introduced, and the characteristics of spatial and temporal variation of precipitation structure under different precipitation durations and precipitation grades were explored by using innovative trend analysis (ITA）, Mann-Kendall test and inverse distance weighting (IDW) method. [Results] (1) The precipitation occurrence rate tended to decrease with the increase of precipitation calendar time, and the precipitation contribution rate tended to increase and then decrease, with short calendar time precipitation dominating in Yunnan Province. Spatially, the precipitation occurrence rate and contribution rate of short calendar period showed an overall decreasing trend from northeast to southwest, while the opposite was true for long calendar period. (2) As the precipitation level increased, the precipitation occurrence rate tended to increase and the precipitation contribution rate tended to increase and then decrease, with light rainfall dominating in Yunnan Province. Spatially, the occurrence rate of light rain was decreasing from north to south, while the occurrence rate of medium rain, heavy rain and heavy rain was the opposite trend. The contribution rate of light and moderate rainfall showed a decreasing trend from northwest to southeast, and the contribution rate of heavy and torrential rainfall showed the opposite trend compared with that of the light and moderate rainfall. The occurrence and contribution rate of heavy and torrential rainfall were higher in central, southern and southwestern Yunnan, which might cause higher risk of flooding. (3) Under different precipitation durations, the occurrence and contribution rate of precipitation at most stations in short durations were increasing with the increase of more than 5%, and in long durations were decreasing with a trend of more than 5%. Under different precipitation grades, the occurrence and contribution rate of light rainfall at most stations showed the decreasing trend within 10%, and the occurrence and contribution rate of heavy rainfall and storms showed the increasing trend above 5%. [Conclusion] In Yunnan Province, the probability of short-calendar-time heavy rainfall and storms had risen, and the chance of flooding and soil erosion in the region had increased, so the precipitation structure should be continuously monitored and researched in the future.

The Jiangchuan Biota from the Jiucheng Member (Mb.) of the Dengying Formation (Fm.), discovered in Jiangchuan, eastern Yunnan, China, is marked by copious macrofossils at the apex of the Ediacaran strata. This fauna features benthic algae with varied holdfasts and other fossils of indeterminate taxonomic affinity and is compositionally unique compared to the Shibantan and Gaojiashan biotas of the Dengying Fm. and the Miaohe and Wenghui biotas of the Doushantuo Fm., elsewhere in China. One novel benthic saccular macroalgal fossil, named here Houjiashania yuxiensis gen. and sp. nov., from the Jiangchuan Biota is based on fossils that are sausage‐shaped, elongate, tubular, ranging from 0.3 to 4 cm in length, and up to 0.8 cm in diameter. One terminus is blunt and rounded to an obtuse angle, the other is bent with a spread‐out surface resembling a holdfast, suggesting a three‐dimensional thallus. Thin, stipe‐shaped outgrowths, likely vestiges of sessile saccular life forms, are prevalent in macroalgal fossils of analogous size and shape, as well as present brown algae Scytosiphonaceae, such as Colpomenia and Dactylosiphon. The new findings augment the diversity of benthic algae, such as those known from the Early Neoproterozoic Longfengshan Biota in North China. The benthic algal macrofossils in the Jiucheng Mb. add to knowledge of Late Ediacaran metaphyte diversification and offer more clues about the evolutionary positioning of primitive macroalgae. The co‐occurrence of numerous planktonic and benthic multicellular algae and planktonic microbes might have facilitated ecologically the more extensive later Cambrian explosion evidenced by the Chengjiang Biota in Yunnan.
