In this paper, a quantatative remote sensing method for soil erosin losses is briefly introduced, and its operation and application in the mountain and hilly areas of Shandong Province, China are described.Although the model form of this method for monitoring soil erosion losses is the same as that of the (American) RUSLE, the formula and algorithms for model factors are generated from the loss data observed in China.Therefore, the method is more applicable to loss regions in our country and is suitable for personal computers to process the data of GIS and remote sensing.It is a more accurate and practical method compared with the conventional survey method and the qualitative remote sensing method.The results of its application include the total loss of region, the area of different grades of soil loss, the soil erosion map, and the forecast map of soil conservation.The total losses monitored by the quantitative remote sensing method are conformable to the deposition values observed and calculated by hydrometric stations in the 9 reservoir valleys with an average accuracy of 82.96%, showing the accuracy of the monitoring results obtained by this method in Shandong Province (see Table 2).
