摘　　要：沂源县位于淮河流域最北部,地处沂蒙山区,地形以山地为主,土壤侵蚀严重.笔者以GIS为工具,以RS为主要数据来源,利用中国土壤流失方程（CSLE）,对淮河流域沂源县的土壤侵蚀情况做出估算,得出沂源县土壤侵蚀总量及其分布规律,为今后的土壤侵蚀动态监测及水土保持工作提供依据.Yiyuan county is located in Yimeng mountain areas, north of Huaihe River basin. Mountains and hills are the dominant terrain. Soil erosion by water is a serious problem here. This paper used GIS as the main tool, RS as the source of data. Gross and distribution law of soil erosion were obtained through estimating the soil erosion in Yiyuan county by Chinese Soil Loss Equation （CSLE） model which was established by Liu Baoyuan. Based on the computations, we found that in the past five years, soil erosion treatment in Yiyuan county has had a good effect. The slight soil erosion and light soil erosion areas accounting for 71.85% of the study area, it is 2.76% more than the data obtained from remote sensing investigation in 2005. From the final distribution map of soil erosion intensity, we found that soil erosion distributed mainly in hilly areas where elevation is low. The human activities have great influence on this area, but at the same time, middle degree erosion and above areas account for 28.15% of the total study area, it reveals that soil erosion in Yiyuan county is still serious. So soil and water conservation engineering measures should be adopted to prevent the loss of water and soil erosion.
