Other AbstractIn the Aixigou watershed of the Jinsha River, its production capability is backward, soil and water loss is heavy and the anti-erosion ability of soil is not good, all of which cause the Aixigou watershed the main sediment provider of the upper reaches in the Jinsha River. The study on the soil erodibility factor K is the foundation of the soil and water conservation in that area, not only could help to conserve the soil loss of the grassland and farmland, but also could help to reduce the sediment in the Jinsha River. Based on the investigation results of the soil anti-erosion ability and soil erosion characteristics, this paper compared 3 kinds of classical model methods of soil erodibility using various field investigation data. The digital feature, the relationship between the predicted value and the field investigated value and the reliability of the predicted value span were comparative studied. As a result, the best model for soil erodibility estimation in the study area was the USLE-K model, the K value order of different soils was grey cinnamonic soil>alpine meadow soil>brown soil>dark brown forest soil, and the average K value of the watershed was 0.005 which was low around the country
