Abstract:To dynamically monitor soil and water conservation in H ubei Province, the three factors of vegeta-tion, slope, and landuse are incorporated in the fast estimation of soil erosion using MODIS images and other investigated information. First, a vegetation coverage map is extracted from MODIS images. Second, a land-use distribution map is obtained from TM images. Third, a slope map is created from DEM. Finally, based on the standards of soil erosion grading, a soil erosion distribution map is obtained by overlaying the maps of landuse distribution, vegetation coverage, and slope. Based on geographic information system(GIS), the de-gree and distribution of soil erosion in Hubei Province are quantitatively analyzed using MODIS images in 2004 and 2005 and the change of soil erosion from 2004 to 2005 is analyzed.
