In order to explore the hotspots and research trends of domestic research on biochar in tobacco agriculture in recent years, bibliometric methods were used to analyze papers about biochar application in tobacco planting research included in the China National Knowledge Infrastructure (CNKI). The numbers, annual distribution, author information, publications and research content were statistically analyzed, and the CiteSpace V visualization software was used to predict and analyze research hotspots. The results showed that a total of 114 journal papers and 81 dissertations on the application of biochar to tobacco planting were retrieved, including 8 doctoral dissertations and 73 master’ s dissertations. The institution with the most research in China was Henan Agricultural University, and Liu Guoshun was the scholar with the most published papers. Domestic research on tobacco biochar still lacked a stable core author group, and the number of core authors was small. Tobacco biochar application hotspots focused on tobacco quality, chemical composition and tobacco-growing soil. In recent years, research hotspots tended to be on the effects of biochar on soil microbial communities and heavy metals in tobacco leaves. [ABSTRACT FROM AUTHOR]

Traditional Chinese clothing patterns are an important part of excellent cultural heritage of China with unique visual effects and artistic charm providing abundant materials for modern design. They are widely used in the field of modern design and decoration and are an important symbol of the nationalization of Chinese design. Over the past 20 years scholars have conducted increasing research on traditional clothing patterns and explored the integration of traditional clothing patterns with modern design languages from different perspectives and different disciplinary backgrounds as well as the digital simulation and reconstruction of traditional clothing patterns. At present there is a lack of comprehensive quantitative analysis to objectively evaluate relevant research literature on traditional clothing pattern design transformation and there is an urgent need to grasp the theoretical trends in this field as a whole. This paper selected 425 journal articles on traditional clothing pattern design transformation research from CNKI in the past 20 years. Based on the CiteSpace software and content analysis method the research laws of traditional clothing pattern design transformation in China were sorted and analyzed from the dimensions of knowledge production context knowledge production subject knowledge foundation keyword co-occurrence and timeline. This paper adopted a dual perspective of bibliometrics and content analysis to clarify the research laws of traditional clothing pattern design transformation from the dimensions of time and space in order to provide reference for theoretical deepening application exploration and sustainable development in this field. Three major conclusions were drawn. First from the basic characteristics of the literature the number of publications on traditional clothing pattern design transformation has increased rapidly since 2001. Scholars have paid increasing attention to related research in the field of traditional clothing pattern design transformation. More scholars and research institutions have explored the traditional clothing pattern design transformation to varying degrees from different disciplinary backgrounds and accumulated a certain number of research results. However most of the scholars conduct independent research indicating a lack of collaborative research on the traditional clothing pattern design transformation. Therefore it is necessary to form more academic research teams and core research scholar groups. Second from the perspective of hot research topics the research on traditional clothing pattern design transformation has formed three research hotspots materialized expression of auspicious culture in traditional clothing pattern design transformation innovation of methods for extracting traditional clothing patterns and interdisciplinary integration driving the innovative development of traditional clothing pattern design transformation. Third from the perspective of research evolution the evolution of traditional clothing pattern design transformation can be roughly divided into three stages 2001 - 2008 2009 - 2016 and 2017 - 2022. The integration of multiple disciplines drives the continuous innovation of modern design and forms new development trends. For example the interactive design of traditional clothing patterns provides users with a better user experience traditional clothing pattern service design based on user emotional experience has become an emerging research direction the extraction and innovation of "Chinese elements" in traditional clothing patterns reflect cultural confidence in design transformation the traditional clothing pattern design transformation has gone through a change from commonality to individual psychological needs with design shifting from practicality to spirituality.

Thanks to the cultural turn in human geography and the spatial turn in sociology, the space of "home, " is a multi-dimensional assemblage full of material, social and emotional elements. This paper utilizes CiteSpace and Bibliometric to analyze the papers on the geographies of "home" in the WoS core collection and CNKI Chinese core journal. By figuring out its cur‐ rent developments, including the number of papers, researchers and their institutions, published journals, research topics and important achievements, we summarize the overall characteristics and latest progress of Chinese and international researches on the geography of "home". It is found that this research has witnessed great development since the 21st century, while most focused on Western developed countries and regions. Besides, a number of research groups have been formed in many universities and research institutions. On the other hand, the geography of "home" in China is in its infancy for its insufficient researchers and outputs. In international academia, the journals of the geography of "home" have stronger academic influence, but the average citation frequency is low. In China, the journals are mainly hosted by the Institute of Geographic Sciences and Natural Resources Research, CAS. The average citation frequency of papers is significantly higher than the journal's impact factor. Research topics of the geographies of "home" are variable, such as mobility, transnational migration, gender and family. In recent years, there have been more research hotspots which have close relationships with the latest international current affairs. Chinese scholars tend to focus on mobility, the home of commerce and spatial practice and share many similar research interests with international researchers. However, discussions on "home" in the context of Chinese culture are still under-explored. [ABSTRACT FROM AUTHOR]

In order to keep up the research dynamics in the field of nitrogen monitoring in wheat, this paper explores the current status and content evolution through visual analysis. Using bibliometric methods, we mined the trend of publications, subject areas, countries, institutions, journals and highly cited papers, research hotspots, and theme evolution between 1990 and 2022, and analyzed the intersection of disciplines and the concentration of literature. The research found that the global publication volume is generally on the rise, and China is the fastest growing country in recent years, but it can be further improved in terms of the number of local citations and the total number of citations. The field of wheat nitrogen monitoring has changed from one single discipline to multidisciplinary, the hotspots have evolved from the analysis of a single physiological process to the monitoring of remote sensing, crop modeling, growth simulation, and other directions. The research hotspots have evolved from the early stage of single physiological process analysis to the direction of digital agriculture, forming two major research nodes in the world represented by China and the United States. Six of the top ten authors are from China, and China occupies six seats in the top ten organizations, and China ranks in the top in all four indicators of highly cited papers. As time goes on, the tendency of teamwork and international cooperation has become evident, and the proportion of collaborative publications between China and the top ten countries is 31.48%. Agronomy journals are the main publications, with Field Crops Research being the most representative. The results show that the cross-disciplinary trend has become more and more obvious, the development trend of research hotspots and fields has become clearer and clearer, and in the future, the in-depth cooperation among different countries, disciplines, and teams will bring greater and more far-reaching opportunities.

Achieving carbon neutrality is an important response to climate problems, and existing studies lack a summary analysis of its hot spots and evolution. Based on Bibliometric methods, this paper analyzed the "carbon neutrality" and related topics in the core collection of Chinese database CNKI (3 674 articles) and foreign database WoS (9 733 articles). The findings are as follows: (1) Highly cited CNKI literature has less research on technical methods than WoS literature; (2) Authors of Chinese and foreign literature cooperate more within the team and less among the teams; (3) Institutions with closer geographic locations cooperate more. Most publishing agencies come from China with the largest number of publications, but their influence is less than that of developed countries such as the United States; (4) Carbon emission is a hot issue in both types of literature. CNKI literature focuses on the decomposition and accounting of carbon emission factors, WoS literature focuses on the assessment of emission reduction effect and technical research methods. Finally, the paper looks ahead to energy efficiency and energy transformation, carbon trading and carbon tax, implicit carbon emissions and other issues. [ABSTRACT FROM AUTHOR]

In order to analyze the research status and hot trends of water resources ecological footprint, this paper takes CNKI and web of science database as data sources, and uses CiteSpace visual analysis software to comprehensively analyze development status and research hotspots of Chinese and English papers in the field of water resources ecological footprint from 2005 to 2020. The former includes the number of publications, sources of literatures, research institutions, authors, regional cooperation networks and highly cited literatures, while the latter includes keyword cluster analysis and hot emergent word analysis. The development status results show that on the study of ecological footprint of water resources, the Chinese literatures are earlier than the English literatures, and the number of published papers of both show an increasing trend, which are the hot research fields at present. The Chinese and English literatures mainly come from the core journals in the field, mainly involving the environment and ecology and other fields. The cooperative network of Chinese literatures research institutions are relatively decentralized, while the cooperative relationship of English literatures research institutions are closer. There are more researchers in Chinese literatures, forming a relatively obvious cooperative subgroup, while there are fewer English literatures writers and most of them are Chinese scholars. Countries such as China, the United States and the Netherlands are the main forces of literature publication. In the analysis of hotspot emergent words, the intensity of ecological footprint is the highest, indicating that the research of water resources ecological footprint has entered a mature stage. In the future, the depth and breadth of research in the field of water resources ecological footprint should be strengthened to achieve interdisciplinary integration. [ABSTRACT FROM AUTHOR]

In order to clarify the development process of landscape architecture research and look forward to the potential development direction of landscape architecture in China, using bibliometrics and CiteSpace information visualization software, 7 164 research literatures on landscape architecture in CNKI database from 2011 to 2020 were analyzed to determine the current situation and the trend of landscape architecture research during this period. The results showed that the quantity of annual published papers increased first and then decreased, reaching the maximum in 2019 and then decreasing. The discipline fields mainly were focused on engineering, horticulture and economics, and the publications were mainly distributed in engineering technology and basic and applied basic research, which was less in line with humanities and social sciences. Meanwhile, the national and local financial support for related research was low. Planning and design, teaching reform and construction had been the research hotspots of landscape architecture development in the past ten years, but there were differences in the research hotspots in different periods, and the research fields showed the characteristics of diversification. The development of landscape architecture was divided into two stages, which were the research stage of basic research on plant landscape, planning and design, construction and teaching mode and teaching method from 2011 to 2015, and the research stage of conservation technology, energy-saving technology, natural protected area and landscape regeneration from 2016 to 2020 were mainly focused on ecological concept and low-carbon concept.

Biological invasions seriously threat the global biodiversity and ecosystem health, causing great losses to global environment and economy. However, rapid climate change could significantly affect the diffusion and invasion of alien species. To explore the development situation of biological invasions under climate change could be helpful for better understanding the status and hot spots in this field, and also the benefitial for understanding the invasion mechanism and making effective management measures. In our study, we studied the Web of Science(WOS)database for publications pertaining to the biological invasions under climate change between the years 1990-2016, we then used the Thomson Data Analyzer(TDA)to operate the systematic analysis. We found that there were total 1 736 published papers in recent 27 years. The number of publications increased annually, while it rapidly increased since 2009. This research area related to several subjects such as environmental science and ecology, biodiversity protection, botany, etc. Prof. Chown SL form Monash University had the largest amounts of publications. USA had the maximum total papers, highly cited and high impact factor papers. California University published the most papers among international research institutes, while the Chinese Academy of Science(CAS)ranked the 10th. Biological Invasions was the academic journal which had the largest publications. Recent studies focused primarily on topics related to species distribution models, biodiversity, global warming and risk assessment. China totally published 52 articles, Chinese Academy of Science had the largest amounts of papers, while Institute of Zoology, Wuhan Botanical Garden, Institute of Botany ranking Top 3 among the branch organizations of CAS. In the future, China should give more attentions on the high level research papers and international cooperation of biological invasions under climate change. In addition, we need to focus on prediction and risk assessment of alien species, relationships between biological invasions and biodiversity, system evolution of invaders, relationships among multiple trophic levels of invaded ecosystem, marine biological invasion, influence of invasion on human health, etc under a rapid global climate change.

Objective To discuss the development of ADR monitoring in Chinese medical institutions by the bibliometrics. Methods Literatures from CNKI.net, VIP and Wanfang Database were retrieved, then to compliant literatures were screened according to inclusion requirements, and the bibliometric indicators were used to analyze by bibliometric metrology. Results 4079 literatures were screened compliantly. The trend in the annual number of literatures about medical institutions ADR reports was overall upward 1990-2015. Top 20 of journals covered for 54.55% of all papers analyzing ADR reports. Distribution of journals published ADR literatures publication showed significant Bradford features. The top six provinces published cumulative amount ratio close to 50%, which showed regional distribution of literature. The proportion of published literatures from medical institutions in the prefecture-level cities was the largest (50.87%), the average of literatures amount in the capital cities was largest, 5 mulriple of the county cities. Pharmacists were the main author group of writing papers which analyzing medical institutions ADR reports, accounting for 87.01%. Conclusion The changes in the annual number of literatures which analyzed medical institutions ADR reports could reflect the development process of ADR monitoring in China. The level of ADR monitoring research was related to the level of regional economic development. [ABSTRACT FROM AUTHOR]
