Abstract：Regional soil erosion model is a effective tool for regional soil erosion survey and policy-making of water and soil conservation.This thesis attempts to develop regional soil erosion model,according to the oversea regional soil erosion model,the study region was divided into regular cells based on DEM.The sub-process of interception,infiltration,surface storage were quantitatively described.Transportation and Accumulation of runoff among units was calculated by means of spatial analytic function of GIS.According to using the concrete data of the Yanhe drainage basin to calculate,the result reflects the tense and spatial tendency and difference of soil erosion.It will support macro-decisions of soil and water conservation.
