摘　　要：长期岩溶作用导致的双层岩溶水文地质结构,使岩溶区的水循环过程(含水的流失)和土壤侵蚀过程具有特殊性和复杂性,且受到岩溶地质条件的影响。基于岩溶环境空间分异大的特点,在分析水循环、土壤侵蚀过程的基础上,根据不同尺度区域水土流失的特点分别提出坡地、洼地(谷地)及流域水土流失的防治对策。The long-time karstification leads to the dual structure of karst hydrogeological,which resluted in the process of water cycle（including water loss） and soil erosion being distinctive,complicated,and affected by karst geological conditions.Considering the spatial variation of karst environment is significant,by analyzing the process of water cycle and soil erosion this paper proposes the measures for controlling soil and water loss at slope land,depression and watershed scales according to the characteristics of soil and water loss.
