This article inquired into talked about the improvements in calculating slope gradient,vegetation coverage and the working processes and working styles for soil erosion assessment,taking the Ansai County as an example.The results showed that: There were great change in slope gradient after re-scaling of slope gradient calculated from DEM with 50m resolution.Slope gradient in 98% of the studied area became larger with a varied extent.Mean slope gradient in the studied area increased by 14.5°.There was an inc...
