We used the Revised Universal Soil Loss Equation (RUSLE) as the erosion model for monitoring soil erosion, built up a spatial database, and estimated the soil loss in the study area supported by PAMAP GIS. Results show that the annual total soil loss in Anshun adds up to 86777 tons/year, and the average soil erosion loss reaches 409.4 ton/km (super 2) /year. This method is accurate and useful in quantitatively monitoring soil erosion in the Guizhou karst areas.
