摘　　要：水土漏失是岩溶区特有的水土流失问题,自21世纪以来才逐步开展研究与防治工作。本文在系统分析把握已有相关研究进展的基础上,阐明西南岩溶地区水土漏失的特点,揭示以岩溶地下河流域为单元开展水土漏失过程系统研究的重要性,总结水土漏失监测评价和影响因素等方面的研究进展。指出目前的水土漏失研究在岩土缝组构刻画、水土漏失关键过程和机制、水土漏失评价模型等方面存在不足。面向西南岩溶区水土漏失防治的国家目标和国际前沿研究方向,提出下一步应开展岩溶关键带水土漏失网络研究、水土漏失关键过程系统研究、以及水土漏失评价模型构建和应用3个重要方向的工作。[Background]Soil and water leakage is a specific soil and water loss issue in karst areas,it is most serious in the karst area of Southwest China,and causes severe resource and environmental issues such as soil loss from farmland,rocky desertification,depression water logging and pollution to cave landscape.Because the karst structures in Southwest China are complex and soil leakage studies were begun after the 21st century,the theoretical and technologic system of soil and water leakage have not been formed.Based on systematically analyzing relative papers,this review aims to present the main research progresses,shortages,and the next research directions on soil and water leakage in the karst areas of Southwest China.[Methods]In order to accurately grasping the important research progresses and shortages,the authors took soil and water leakage,karst,soil and water conservation,and Southwest China as the key words,and collected over 200 relative papers from all literature database at home and abroad.The authors chose 76 papers as references of this review;after focused the four important aspects of this paper such as feature,processes,monitoring and evaluation,and mechanism of soil and water leakage in the karst areas of Southwest China,and excluded many papers that were not closely relevant to this review s target.[Results]1)This review clarified four features on the soil and water leakage of karst areas in Southwest China,i.e.,geological concealment of soil and water leakage processes,relative low soil loss tolerance,geomorphological differences of soil and water leakage,and difficulty of treatment project of soil and water leakage.2)This review revealed the importance of systematic studies on the soil and water leakage processes in karst ground river basin after concluding research progresses on processes,monitoring,evaluation and influence factors of the soil and water leakage,.3)Three defects of present studies on the soil and water leakage in karst areas of Southwest China are gave,especially on quantitativ
