Abstract For exploring the effects of the ecological restoration project on soil erosion,3S technique is used to monitor spatial and temporal changes of soil erosion and to explore the changes of soil erosion by four restoration measures both in area and in intensity.The result indicates: soil erosion in the region is being alleviated;soil erosion both in area and in intensity are reduced obviously by ecological restoration measures;the biggest function to control soil erosion in different measures is reinforcement planting in the open forest land,and others in turn are the economic forest taking back for afforestation,reforestation in the wild land on slopes and closing land for reforestation.The research results can provide the reference for the benefits appraisal of ecological restoration project and determining the reasonable measure of ecological restoration.
