Review on Hillslope Erosion Prediction Models in China

By the research of hillslope erosion prediction model,the knowledge about the process and the mechanism of soil erosion were strengthened,and the arrangement of soil and water conservation practice on hillslope were supported.The quantificational evaluation and the research of prediction model about hillslope erosion were divided into three stages in China:(1) Hillslope erosion statistical model based on USLE (Universal Soil Loss Equation);(2) Steep hillslope soil erosion prediction model;(3) Physically based hillslope erosion prediction model.Finally,considering special erosion sediment and the complex terrain in our country,some intensified aspects on the establishment of hillslope erosion prediction model were advanced,which were the research on the process and the mechanism of ephemeral gully erosion,the equation of interrill flow,rill flow,ephemeral gully flow,modeling of steep hillslope.
