In combination with the features of soil and water conservation zoning in first grade and the features of topographic structure in different areas,9 typical indexes related to soil and water conservation,forming an appraisal index system composed of the target layer,criterion layer,limit layer and index layer,were constructed in this paper,to calculate the coefficient of each index for comprehensive index of soil and water erosion impact depending on expert decision and Hierarchical assignment. The study showed that division for layer structure of evaluation index system was more scientific and reasonable,and the comprehensive indexes obtained with analytic hierarchy process could reflect properly the degree affected by soil and water erosion and its potential value.
