Remote sensing data, DEM, land use and land cover GIS data are used to monitor soil erosion in Mingjing River valley. Instead of using the field sample sites parameters for the USLE model calculation we extracted the parameters from satellite data. Landsat TM and ETM temporal data were used to investigate the changes in between 1993 and 2000. The results prove that there was /spl plusmn/5% soil erosion difference between our calculation results from ETM data in 2000 and field statistical results in 1999.
