黄河流域生态环境与经济发展耦合胁迫关系研究

Examining the Coupling Degree and Interactive Stress Between Ecological Environment and Economic Development in the Yellow River Basin

为探究黄河流域生态环境和经济发展之间的耦合胁迫关系,给黄河流域生态保护和高质量发展决策提供参考,建立了黄河流域生态环境与经济发展综合评价指标体系,并运用耦合协调和交互胁迫模型分析了黄河流域9个省(区)2007—2017年生态环境与经济发展的关系。结果表明:在时间序列上,研究时段初期黄河流域生态环境与经济发展耦合协调状况处于严重失调状态,后期整体处于良好协调状态,整体上越来越协调;在空间格局上,研究时段初期黄河上中游省份生态环境和经济发展之间协调程度高于下游省份的,后期黄河上下游省份的协调程度高于中游省份的,黄河中游地区生态环境与经济发展的关系还需要进一步调整;经胁迫关系验证,黄河流域生态环境与经济发展存在一定的交互胁迫关系,研究时段前期生态环境综合指数大于经济发展综合指数,后期经济发展综合指数大于生态环境综合指数,生态环境的改善具有一定的滞后性。

In order to explore the coupling degree and interactive stress between ecological environment and economic development of the Yellow River basin and provide reference for the ecological protection and high⁃quality development decision⁃making of the basin,This paper analyzed the relationship between the ecological environment and economic development of nine provinces(regions)in the basin from 2007 to 2017 by using coupling coordination and interactive stress model.The results show that in terms of time series,the coupling coordination be⁃tween the ecological environment and economic development of the Yellow River basin is in a serious maladjustment state in the early stage,and in a good coordination state in the late stage,and it is more and more coordinated in the whole researched period;in terms of spatial pat⁃tern,the coordination degree between the ecological environment and economic development of the upper and middle reaches of the Yellow River is higher than that of the lower reaches of the Yellow River in the early stage,and the coordination degree of the upper and lower rea⁃ches of the Yellow River is higher than that of the middle reaches of the Yellow River,the relationship between ecological environment and economic development in the middle reaches of the Yellow River needs further adjustment;through the verification of the stress relationship,there is a certain interactive stress relationship between ecological environment and economic development in the Yellow River basin.In the early stage of the study period,the comprehensive index of ecological environment is larger than that of economic development,in the later stage,the comprehensive index of economic development is larger than that of ecological environment and the improvement of ecological envi⁃ronment has a certain lag.
