摘　　要：[目的]探究矿业城市生态安全状况,厘清制约生态安全发展因素,为安徽省矿区可持续开采提供科学依据。[方法]以安徽省9个矿业城市水土生态安全为例,构建基于经济—环境—社会的综合评价指标体系,通过乘法归一化法结合优化后的G1和CRITIC赋权法实现主客观赋权,再运用多准则妥协解排序法(VIKOR)模型,基于折中规划考虑了群体效应和个体妥协,兼顾不同权重指标实测值的差异性,利用障碍度模型对其进行障碍因子诊断。[结果]多指标交互作用下的G1-CRITIC-VIKOR综合模型与实际数据匹配良好,安徽省矿业城市水土生态安全水平由高到低排序为池州、宣城、滁州、铜陵、马鞍山、宿州、亳州、淮北和淮南地区;其中工农就业人员比例、水土资源匹配系数、人均用水量、土地垦殖比例、城乡人均可支配收入是制约安徽省矿业城市水土生态安全水平的关键因素。[结论]安徽省矿业城市应积极进行生态文明建设,努力把经济向集约型经济转变;实施植树造林,做好受损矿区生态修复、重建工作,保障其在水土生态安全的基础上科学合理地开采煤矿资源。[Objective] The status of ecological security in mining cities was determined and the factors restricting the development of ecological security were clarified in order to provide a scientific basis for sustainable mining in Anhui Province. [Methods] A comprehensive evaluation index system based on economy-environment-society was constructed for soil and water ecological security of nine mining cities in Anhui Province. The multiplicative normalization method was used to combine the optimized G1 and CRITIC weighting methods to achieve subjective and objective weight assignment. Then, the VIKOR model was used to consider the group effect and individual compromise based on compromise programming, and the difference of measured values of different weight indexes was taken into account. Finally, an obstacle degree model was used to diagnose the obstacle factors. [Results] The G1-CRITIC-VIKOR model under the interaction of multiple indicators produced results that were well matched with the actual data. The nine mining cities in Anhui Province were ranked(from high to low) based on their soil and water ecological security levels as Chizhou, Xuancheng, Chuzhou, Tongling, Ma’anshan, Suzhou, Bozhou, Huaibei, and Huainan. The proportion of workers and peasants employed, the matching coefficient of water and soil resources, the per capita water consumption, the proportion of land reclamation, and the per capita disposable income were the key factors restricting the level of water and soil ecological security of mining cities in Anhui Province. [Conclusion] The mining cities in Anhui Province should actively carry out ecological civilization construction and strive to transform their economies into intensive economies. At the same time, afforestation efforts should be implemented for ecological restoration and reconstruction of damaged mining areas so as to ensure the scientific and reasonable mining of coal resources on the basis of ecological security of water and soil.
