A quantitative method of remote sensing for soil erosion is described in this paper. Although form of the model for monitoring losses in the method is the same as the USLE and RUSLE, the formula and algorithms for model factors are generated from loss data observed in our country. Therefore, it is more applicable to loss regions in our country, and suits personal computer proccssing of the GIS and remote sensing data. The results of its application which include the total loss of region, the area of soil loss grades, the soil erosion map and the forecast map of soil conservation, are more accuracy and useful than those of existing methods for the conventional survey and qualitative remote sensing.
