Based on Universal Soil Loss Equation and methods of mathematics model and GIS analysis, we classified influence of precipitation, soil, topography and vegetation upon sensitivity of soil erosion into five different degrees. As a result, assessment map of each factor was finished. We also drew integrated assessment map of sensitivity of soil erosion by overlapping function with Arcinfo. Furthermore, we analyzed distribution characteristics and spatial difference of sensitivity of soil erosion in Tibet under special plateau environment. According to sensitivity degree, priority erosion control areas were confirmed so as to provide scientific basis for departments of water conservancy, traffic management and agriculture which could make scientific and reasonable decisions.
