| Abstract: | In this paper, problems currently existing in soil and water conservation researches in China were briefly reviewed, and meanwhile, soil and water conservation technical measures with ‘runoff regulation’ as a main method and erosion sediment yield mechanism based on hydrodynamic characteristics and also research direction and significance were proposed. A systematic summary of soil and water conservation measures with ‘runoff regulation’ as a main method, indexes for runoff and sediment reduction effects and mechanism of soil erosion process as well as a discussion of main problems existing in dynamic process of runoff regulation and overland flow erosion and research of urgent need were made. |
