| Abstract: | Based on the spatial analysis function of GIS,this paper integrates USLE to estimate the soil erosion in Zhuxi River watershed.Reasonable methods are adopted to obtain R,L,S,K,C and P factor values.Results show that the annual average soil erosion amount is 1 023.26 t/km2,which is in the classification of low-grade erosion.The areas with medium and higher degree of erosion are key areas,where prevention and control measures should be taken.The paper also analyzes the spatial distribution pattern of soil ero... |
