摘　　要：模糊综合评价方法可以较好地解决生态系统健康评价存在的模糊的、不确定性的问题。以山东义桥矿区为研究区域,建立矿区生态系统模糊综合评价指标体系,计算出隶属度函数,确定评价指标体系权重再进行熵技术修正,最后计算出矿区各项指数的生态现状健康值。结果表明:模糊综合评价模型对生态环境评价分析结果清晰,系统性强,具有较高的科学性和可行性,在义桥煤矿村下开采矿区生态环境演变分析中得到应用。Fuzzy comprehensive evaluation method can solve fuzzy and uncertain problems of ecosystem health assessment.A comprehensive ecosystem fuzzy evaluation indicator system based on Yiqiao Mine in Shandong province is established in this paper and membership function is calculated.And then the weights of evaluation indicators are confirmed,which are revised by entropy technology.Finally the current health values of mine are calculated.The results show that the fuzzy comprehensive evaluation model can clearly analyze ecological environment with its high systematicity,scientificity and feasibility,which has been proved in environmental analysis of Yiqiao Mine.
