| description | Anning River basin as an important soil erosion monitoring and reserve in Sichuan Province. It is of great significance to grasp the temporal and spatial changes of soil erosion in this area in time to realize the comprehensive treatment of regional soil erosion. Based on the revision of the general soil erosion equation (RUSLE), the present situation of soil erosion erosion in 1995-2015 years in this area was monitored, and the classification was completed according to the national grading criteria, and the following results were mainly achieved:(1) Soil erosion in Anning river basin as a whole presents a low gradient change in the eastern High West.(2) The proportion of raster in soil erosion area of each grade also showed different structural differences, which showed that the degree of micro > Mild > Moderate > Strong > Extremely > severe, and the proportion of raster in mild and below intensity erosion area reached more than 80%, and the whole basin was at mildly below erosion level.(3) One-dimensional linear regression analysis shows, within 20 years, about 90% of the raster cell slope in this area is negative, the overall change trend of soil erosion in this area shows a significant improvement |
