摘　　要：详细提出矿区生态系统健康现状模糊综合评价方法:首先建立矿区生态系统健康综合评价指标体系;其次用层次分析法(AHP)确定指标的权重系数,并利用熵技术对权重系数进行修正;然后计算评价指标隶属度,并采用3层次模糊综合评价方法进行评价;最后,根据实际需要采用最大隶属度法或分值法对评价结果进行处理。该评价方法首次采用层次分析法和熵技术来确定评价指标的权重系数,首次采用最大隶属度法或分值法对评价结果进行处理,为矿区生态系统健康现状定量评价提供了基础。该方法仍需进一步结合矿区的实际情况,对评价指标、一些指标的权重等进一步完善,以期推广应用。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.
