The comprehensive evaluation of analytic hierarchy process (AHP)and fuzzy mathematics combines AHP with fuzzy mathematics. A more accurate evaluation through choosing the advantages of the two methods can be achieved. In this paper,taking the sand mining area in Changping of Beijing as the study area,the authors applied the comprehensive evaluation of AHP and fuzzy mathematics to the evaluation of the ecological environment and, with the help of remote sensing, to the monitoring of the ecological environment of the mining area. The ecological evaluation index system was established through the selection of the six indexes comprising density of the water bodies,vegetation coverage,residential density,topography,mining occupies and ecological diversity. Then the weights of the evaluation indexes were determined by using the fuzzy mathematics comprehensive evaluation method based on AHP,and the evaluation factors were superimposed on the platform of GIS to get the evaluation map of ecological environment for the ecological environment evaluation of the mining area. The results show that the method proposed in this paper is an effective method for the evaluation of ecological environment of the mining area, and has an important practical significance for the protection of the ecological environment of the mining area and the rational development of mineral resources.
