摘　　要：耦合协调发展水平的测度对于研究煤炭工业可持续发展具有重要意义。根据煤炭工业资源-环境-经济系统耦合机制,构建了该系统的评价指标体系,利用熵权法和TOPSIS法计算煤炭工业资源-环境-经济系统以及各子系统的评价值,通过耦合协调度模型计算耦合协调度,评估煤炭工业的资源-环境-经济系统的耦合协调水平。结果表明:2008—2018年,榆林市煤炭工业资源-环境-经济系统综合评价值呈U型变化趋势,与环境子系统评价值变化趋势相似,有明显提升;煤炭工业资源-环境-经济系统耦合协调水平不断优化且均处于协调范围,呈现平稳—下降—上升的趋势,2018年耦合协调度为0.86,达到良好耦合协调水平。The measurement of coupling coordination level is of great significance for the study of sustainable development of coal industry.According to the coupling mechanism of the resource-environment-economy(REE)system of coal industry,the evaluation index system was constructed.The evaluation values of coal industry REE system as well as that of each subsystem were calculated by entropy weight method and TOPSIS method.The coupling coordination degree was calculated by the coupling coordination degree model to evaluate the coupling coordination level of coal industry REE system.The results showed that the comprehensive evaluation value of coal industry REE system in Yulin City showed a"U"type trend,which was similar to the evaluation value of environment subsystem and had an obvious improvement.The coupling coordination level of coal industry REE system had been continuously optimized and was in the coordination range,showing a steady-downward-upward trend.The coupling coordination degree was 0.86 in 2018,reaching a good coupling coordination level.
