Abstract: Put forward a fuzzy comprehensive evaluation method of mining area ecosystem health status in this paper. First of all, establish an indicator system of the mining area ecosystem health status evaluation. Secondly, use analytic hierarchy process (AHP) to determine the weight coefficients of indicators, and amend the weight coefficients by entropy technology. And then, calculate the membership grade of evaluation indicator. And adopt a three-level fuzzy comprehensive method to evaluate. Finally, adopt maximum membership degree method or score method to process evaluation findings according to the actual need. This evaluation method firstly adopts AHP and entropy techniques to determine the weight coefficient of evaluation index, and firstly adopt maximum membership degree method or score method to process evaluation findings according to the actual need, and these provide the basis for a quantitative assessment of ecosystem health status in mining area. This evaluation method need to be further integrated the actual situation in mining area, such as indicators, weights of some indicators and so on, and improved and perfected in order to spread the application.
