Abstract
This paper collected attribute data of impacting soil erosion factors by RS and GIS, combined soil erosion model, got load and density of soil erosion in Luoning county, Henan province, and analyzed relationship between soil erosion and its main impacting factors. The results indicated soil erosion modulus was 2799.29t/km2.a and load was 6495744t, 61% of the county was tiny or light degree erosion, while the serious eroded area which mainly concentrated in western only occupied 20% of the area, but contributed 57.64% of sediment of whole area. There is a basically positive correlation between soil erosion and slope.
