Abstract：By using the discriminant model of soil erosion intensity in Zhejiang Province, the major factors affecting soil and water losses were determined. Taken the TM data and aerial photographs of scale 1: 10 000 as data sources, the remote sensing monitoring of soil erosion in Zhejiang Province in 2009 were finished by using digital topographic maps and investigating on sample plots. In this paper, the following factors were extracted, the slope degree using the Delaunay TIN, the vegetation coverage by vegetation index and dimidiate pixel model, and the land use information. The degree of soil erosion were determined based on these data by overlay analysis, and the results were verified by field investigation.In conclusion, the area of soil erosion in Zhejiang Province was decreasing.
