Using RS and GIS technology,the authors analyzed the regularity and causes of water erosion desertification in Yunnan Province and put forward the prevention measures.Studies show that the area of water erosion desertification is 35 949.69 km2,accounting for 9.39% of the total land in Yunnan Province.The overall spatial distribution of erosion desertification is determined by geological environment,topography and other natural factors,and is also triggered and exacerbated by human factors.It is suggest that water erosion desertification prevention work should give priority to such regions as mudstone,claystone,carbonate rocks,Quaternary sediments,the vicinity of the south section of Jinsha River - Honghe River fault zone and other six active faults in the typical eastern and central Yunnan plateau middle mountain type landforms.The existing ecological environment protection projects should be improved,the population pressure should be reduced,and the mining and other industrial activities should be regulated to avoid inducing and exacerbating erosion desertification.
