摘　　要：以山西省长治市潞安王庄矿区为研究对象,基于压力-状态-响应(PSR)模型框架建立了一套生态安全评价指标体系,对矿区这一典型的复合生态系统进行生态安全评价。根据指标体系的结构特点,采用网络层次分析法(ANP)确定指标权重,并对评价结果进行权重敏感性分析来确定影响矿区生态安全的敏感性因子。评价结果表明:(1)王庄矿区生态安全综合指数从2006年的0.512增加至2010年的0.644,总体呈逐年上升趋势,2009年以后生态安全状况处于较安全水平,矿区近几年所采取的响应政策对这种状况的改变起到了关键的作用;(2)生态安全综合指数对GDP增长率、废水循环利用率、人均绿化面积等9个指标表现出相对敏感性,主要是因为这些指标权重较大并且变化较为明显。矿区应当特别针对处于低水平的相对不敏感性指标和呈下降趋势的相对敏感性指标采取相应措施,以进一步改善矿区的生态安全状况。This paper evaluated the ecological security of a typical composite ecological system with the case study of Lu An Wangzhuang mining area in Changzhi,Shanxi Province.Based on the pressure-state-response(PSR)model,the evaluation index system was assumed.According to the structural characteristics of the index system,the weights of the indicators were calculated by Analytic Network Process method(ANP),and weights sensitivity analysis was used to determine sensitive factors which affected the ecological security of the mining area.The evaluation results reveals that:(1)the ecological security integrated index of Wangzhuang mining area showed an increasing trend year by year,from 0.560 in 2006 to 0.712 in 2010.Ecological security became relatively safe in this area after 2009 and responsive actions in recent years played a key role to this change;(2)Due to greater weights and more changeable values,9 indicators such as GDP increasing rate,Waste water recycling rate,Per capita green area shows relatively sensitivity to ecological security integrated index.More attentions should be paid to insensitive indicators in low level and sensitive indicators which have downward trend in order to further improve the ecological security of this mining area.
