摘要
Based on GIS and RS software and the revised universal soil loss equation (RUSLE), a quantitative study is made of the soil erosion of the Madigou area, in combination with RS data, topographic maps and rainfall data and so on. The eco-environment effect factors caused by soil erosion, including vegetation index and landscape index, etc., are also analyzed. The results show that the soil erosion is gradually improved,and the sloping farmlands and sloping wastelands are two types of land use with relatively high soil erosion area.
