摘　　要：为了定量评估金属矿山生态安全现状,建立了金属矿山生态安全效应评估指标体系及评估等级标准,采用模糊层次法(FAHP)确定生态安全效应各子系统及其指标的权重,并引入可变模糊集理论,建立基于FAHP与可变模糊集的矿山生态安全效应评估耦合模型.利用该模型对安徽某大型铜矿的生态安全效应进行评估,经计算该矿在生产效应、自然禀赋效应和社会经济效应子系统上属于Ⅱ级,在环境效应子系统上属于Ⅲ级,矿山综合生态安全效应状态属于Ⅱ级.结果表明:该模型计算简便、可信度高,与其他评估方法得到的结果相一致,亦符合矿山实际情况.In order to quantitatively evaluate ecological security current status in metal mines, the evaluation index system and evaluation grading criterions of ecological security effect in metal mines were created. Weights of evaluation subsystem and secondary indexes were obtained by the fuzzy analytical hierarchy process （FAHP）. An evaluation integrated model was built for ecological security effect in metal mines on the basis of FAHP and variable fuzzy sets. The model was applied to evaluate ecological security effect for a large copper mine in Anhui province. Through the calculation of the model, the ecological security effect grade of production effect, natural endowment effect and socioeconomic effect was classified as class Ⅱ ; the environmental effect subsystem was classified as class Ⅱ. The overall evaluation of the copper mine was classified as class Ⅱ. The results show that the model is reliable and flexible and its results are consistent with the actual situations and those of other models.
