Abstract: In order to explore the hotspots and frontiers of water resources research in China's Karst areas, quantitative analysis of the main research forces and temporal and spatial evolution characteristics of water resources research in Karst areas, and explore its development trend, the scientific text data mining visual network analysis software CiteSpace is used to quantitatively analyze the scientific literature related to water resources research in the Chinese Knowledge Network （CNKI） database from 1991 to 2018, the results are represented by visual network from the aspects of research time, keywords and centrality, major research authors and institutions. The results show that the number of research papers on water resources in Karst areas in China has shown a tortuous upward trend over time in the past 30 years, and it has always been a hot spot for scholars. Karst groundwater, rocky desertification, and water resources carrying capacity are the hotspots of water resources research in Karst areas. Su Wei-ci, Liang Hong, Liang Bin and other researchers are authors and knowledge transmitters of water resources research in China's Karst region. The main research institutions include the Institute of Karst Geology, Chinese Academy of Geological Sciences, the Chinese University of Geosciences （Wuhan） and other research institutes and universities. To this end, it is proposed to continue to expand the extension and connotation of water resources research in Karst areas, to comply with the trend of social and economic development, and to seek new solutions.
