| Abstract: | 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. |
