摘　　要：矿产资源开发在带动当地经济发展的同时对区域生态安全造成了严重威胁,对矿业城市生态开展安全评价有助于生态环境的科学治理。以典型矿业城市大冶市为例,依据“压力-状态-响应”(PSR)概念框架确定生态安全评价指标体系,构建生态安全因果关系认知图,结合高斯隶属函数和节点中心度概念,对大冶市生态安全进行了评价,结果表明:大冶市生态安全目前处于Ⅱ级(较低)水平,生态安全的主要压力来自矿冶在GDP中所占比重较高,以及矿山开采遗留下来的大量固废和采空区,同时大冶市的空气质量、水环境质量和土壤环境质量不容乐观,生态环境治理任务依然艰巨。The exploitation of mineral resources posed a serious threat to the ecological security while advancing the development of local economy.The implementation of ecological security assessment of mining-based cities serves the purpose for the scientific management of ecology.Taking a typical mining-based city called Daye as a study case,the ecological security assessment indicator system was determined in accordance with the"pressure-state-response"(PSR)conceptual framework,thus the cause-effect cognitive map of ecological security was constructed,eventually the assessment on ecological security of Daye city was performed by combining the Gaussian membership function with the concept of node centrality.The results show that the ecological security of Daye city was evaluated at levelⅡ(low level),and the main burden of ecological security came from the high proportion of mining and metal-lurgy in GDP,as well as a large amount of solid wastes dump and mined-out area arising from mining operation.Meanwhile,the results of the quality of air,water and soil in Daye city is not so promising that the ecological environment management is still a hard job.
