从矿业城市环境—经济系统脆弱性产生的原因、表征和措施三方面构建了耦合度评价的指标体系,以三维空间建立耦合度评价模型,采用灰色斜率相似关联度模型评价耦合度约束主因子.结果表明2002～2009年铜陵市环境—经济系统经历弱耦合度—较弱耦合度—较高耦合度的变化,耦合度呈递增趋势；铜陵市环境—经济系统耦合发展的主要贡献因子是经济增长和环境质量,主要限制因子是资源供给、环境保护投资和工业固废排放等.%Based on the causes, characteristics and measures of vulnerability of environmental-economic system index ofrnevaluation system for coupling degree was constructed in a mining city-Tongling. The model of evaluation system wasrnconstructed from the three-dimensional space and used the grey slope similarity incidence to evaluate the main couplingrnfactors. The results showed that from 2002 to 2009, Tongling's environmental-economic system went through the weakrncoupling degree to high coupling degree, and the coupling degree was increased. The main factors of the couplingrnenvironmental-economic system were economic growth and the improvement of environmental quality, and the mainrnlimiting factors were the slow development of tertiary industry, the environmental protection investment and insufficientrnmanagement in solid waste.
