摘　　要：在系统总结矿区生态系统稳定性研究的最新成果的基础上,探讨了生态系统稳定性的研究方法,建立了矿区生态系统稳定性评价的关联维数模型,构建了评价指标体系,应用层次分析法确定了各指标的权重,并用熵技术修正指标权系数,可得各子系统的权重,应用胶东某矿区的实际数据进行了评价,结果表明所建模型是正确的.Based on summarizing the new achievements of the ecosystem stability assessment, the research methods on ecosystem stability were discussed, the related dimension models for assessing the ecosystem stability in mining area were given, assessment indicator system was defined. The weights of all indicators were determined by Analytic Hierarchy Process and modified by entropy technology. These models were tested by real data in a typical mine area. The research conclusions show that these models are correct and applicable.
