Abstract 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 signifi- cant ，by analyzing the process of water cycle and soil erosion this paper proposes the measures for control-ling soil and water loss at slope land，depression and watershed scales according to the characteristics of soil and water loss.
