【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.
[Abstract]:In order to quantitatively evaluate the present situation of ecological safety in metal mines, the evaluation index system and evaluation grade standard of ecological safety effect of metal mines were established. The weight of each subsystem and index of ecological safety effect was determined by using fuzzy hierarchy method (FAHP). The coupling model of mine ecological safety effect evaluation based on FAHP and variable fuzzy set is established by introducing variable fuzzy set theory. The ecological safety effect of a large copper mine in Anhui Province is evaluated by using this model. It is calculated that the ore belongs to class 鈪，
