基于文献计量学的国内外土壤健康评价研究进展分析OA

Conducting soil health assessment is of great significance for timely grasping the status of soil health,adjusting soil health management measures,carrying out soil health protection and promoting sustainable agricultural development.Using the CNKI database and the expanded version of the Web of Science Core Collection′s Science Citation Index as the sources of Chinese and English literature,and applying bibliometric methods and tools such as CiteSpace and VOSviewer to sort out and display the knowledge map and research status of soil health assessment research,with the aim of providing references for soil health assessment research.The results showed:① Soil health assessment research had gone through three stages:initial germination,gradual development and rapid development.The number of Chinese and English publications increased rapidly after 2015;② Developed countries such as the United States and Europe had an absolute leading position in soil health assessment research,while the research level and international influence of developing countries such as China were insufficient;③ International soil health assessment research has achieved certain innovative results in evaluation indicators,method systems and management technologies.The current research hotspots mainly focus on health assessment indicators based on biological indicators,evaluation systems based on soil functions and ecosystem services,and management measures for maintaining and improving soil health status.China mainly focuses on soil quality evaluation in soil health assessment research,and has not yet formed a systematic theory and system.In the future,China should strengthen cooperation and exchanges with developed countries,carry out in-depth theoretical and practical research,and enhance the academic level of soil health assessment in China.
