Abstract:: With remote sensing image of Anxi county, six factors including altitude, gradient, vegetation coverage, slope aspect, land use type, soil type were used for assessing potentiality of soil erosion. After calculating the value of soil erosion potential danger of various factors and the weights of all factors which were calculated by the Delphi method and AHP method, we can calculated composite score of soil erosion potential danger by using the mathematical model and ArcGIS 9.2 platform. The results indicated that the composite score of soil erosion potential danger in Anxi was 54, which is the high level.
