摘　　要：以辽宁省锦州市北镇市为研究区域,基于DPSIR模型,从驱动力、压力、状态、影响和响应5个层面构建矿区生态健康指标体系,并结合物元分析法对北镇市矿区生态健康进行评价分析。利用层次分析法确定权重,构建了评价物元、节域和经典域矩阵,最后通过计算关联函数确定了矿区健康等级。结果表明:北镇市矿区生态健康等级为“健康(Ⅳ)”,从各指标层面来看,其中矿区人均GDP、矿区水质达标率、土壤有机质含量、矿区居民人均可支配收入、人均耕地面积和三废综合治理率等6项指标影响最为突出,但空气质量指数、地质环境治理率等指标的健康等级有待提升;从DPSIR各层面来看,经过健康等级综合关联度计算,各层面均为健康及健康以上。Based on DPSIR model,the ecological health index system of mining area in Beizhen City,Liaoning Province,was constructed from five levels of driving force,pressure,state,influence and response.Moreover,the ecological health of mining area in Beizhen City was evaluated and analyzed with the method of matter element analysis.AHP was used to determine the weights,and the matrix of evaluation matter element,node domain and classical domain was constructed.Finally,the health grade of mining area was determined by calculating the correlation function.The results showed that:Beizhen city mining area ecological health level as the“health”(Ⅳ),From the perspective of each index level,six indicators,including per capita GDP of mining area,water quality up to standard rate of mining area,soil organic matter content,per capita disposable income of mining area residents,per capita cultivated land area and comprehensive treatment rate of three wastes,have the most prominent impact.However,the health level of air quality index,geological environment control rate and other indicators needs to be improved;From the perspective of all levels of DPSIR,through the comprehensive correlation degree of health grades,all levels are healthy or above.
