Research direction of the study of soil erosion in the Loess Plateau

Based on the requirements of soil and water ecological construction in the Loess Plateau and the practices of the Yellow River harnessing,research progress on the study of soil erosion in the Loess Plateau in China is reviewed,and some current issues are also listed.Then some suggestion on research direction and content,method and way of soil erosion in the Loess Plateau is addressed.The further research direction of soil erosion in the Loess Plateau is pointed out,including gravitational erosion law,coupling relationship between erosion and sediment of the hillslope-gullyslope system under different soil and water conservation measures,hydrology effects and runoff mechanisms under different vegetation cover,scale conversion in the process of soil erosion,simulation theory and technology about the soil loss in the Loess Plateau,etc.Approaches to the study of soil erosion are put forward,such as construction of observation system for soil erosion tests,application of inversion technology in soil erosion model.
