Vulnerability evaluation of the ecological environment has become a research hotspot in recent years, especially in the mining area. Based on the scientificity, objectivity, systemacity, operability and dominant factors first principles, we build the evaluation indicator system of ecosystem vulnerability for the mining area. By using analytic hierarchy process (AHP), weights are calculated for each indicator and the ecosystem vulnerability is divided into 5 levels:very vulnerable, vulnerable, moderate, moderate, strong and very strong. On this basis, the fuzzy mathematical model is established and the evaluation is carried out combining with expert scoring. The model built is of scientificity, professionalism and reasonability, providing reference for vulnerability evaluation of the ecosystem in the mining areas.
