As an important part of the terrestrial ecosystem, the grassland ecosystem plays an important role in maintaining the balance of the ecosystem, and has irreplaceable social, economic and ecological functions for human well-being, in particular, it plays an important role in the process of karst rocky desertification control in typical ecological fragile areas. In recent years, more and more scholars have begun to pay attention to grassland ecosystem services, but there are relatively few systematic studies on grassland ecosystem services. Therefore, this study conducted comprehensive evaluation and qualitative analysis based on 209 relevant literature sources retrieved from databases such as CNKI (China National Knowledge Infrastructure) and Web of Science. Firstly, the literature was analyzed through annual distribution, research content, research area, research institutions and research topics. Secondly, the research progress and achievements were classified and summarized. Finally, the key scientific problems and future development directions were summarized for the existing research on grassland ecosystem services to improve grassland ecosystem services and promote rural industry revitalization in the karst area.
