Description :
In this study, based on advanced remote sensing and Geographic Information Systems (GIS) technologies, the influences of precipitation, soil, topography and vegetation on soil erosion sensitivity are evaluated. An index system and the classification standard for soil erosion sensitivity assessment in the Tongbai–Dabie Mountainous area are established with soil erosion sensitivity being evaluated and analyzed in order to provide a scientific basis for controlling soil erosion and for making sound ecological engineering decisions. According to the regional conditions, sensitivity is classified into 5 levels : insensitive, mild, moderate, high and extreme. The distribution of erosion sensitivity for the region is analyzed and the various impacts are discussed. The distribution of soil erosion sensitivity levels was very consistent with the intensity of soil erosion.
