摘　　要：利用第3次水土流失普查数据,分析我国目前水土流失总体状况,水蚀、风蚀和冻融侵蚀等不同类型水土流失状况以及东部、东北、中部和西部地区4大经济区域水土流失状况,并对水蚀区侵蚀危险度现状进行了评价。结合水利部开展的第1、2次全国水土流失普查数据,分析15年来水土流失的动态变化情况,以及我国主要江河流域多年来土壤流失量变化的状况。Based on the third soil erosion survey data, this paper analyzes the present status of soil erosion, the status of water erosion, wind erosion and freeze-thaw erosion, and the soil erosion status in Eastern, Northeast, Middle and Western area, and the erosion risk situation in water erosion area was evaluated, Simultaneously, this paper analyzes the dynamic changes of soil erosion during 15 years, comparing with the first and second soil erosion survey data which were pro ed by Ministry of Water Resources, and the change of soil erosion amount in some river basins was analyzed.
