Abstract


Soil conservation service (SC), as one of the most crucial ecosystem services (ES), plays a vital role in promoting the restoration of ecosystem structure. Severe soil erosion in karst areas has resulted in the ongoing degradation of soil conservation services. Understanding the current and evolution of research in this field is essential for establishing a theoretical foundation for the future management of rocky desertification in karst areas. Based on the Web of Science (WOS) and China Knowledge Network (CNKI) databases, 224 articles on SC were collected. This paper summarizes the research progress, results, and development trends from various aspects through systematic review and qualitative analysis of the literature. The findings are visually presented using spatial visualization and analysis tools such as SATI and Gephi. Key scientific issues and future development trends of existing SC are summarized with a view to improving SC in rocky desertification areas. It is of great significance to further improve the layout of ecological engineering construction and rocky desertification management in karst regions.
