黄河流域城市群生态保护与经济发展耦合的时空格局与机制分析

通过研究黄河流域战略背景和城市群发展规划,本文构建评价生态保护和经济发展的指标体系并运用于城市群比较研究中,再依据耦合协调度模型、空间自相关和地理探测器,分析黄河流域七大城市群2007—2019年生态保护与经济发展耦合协调时空特征与驱动机制。结果表明：（1）研究期内黄河流域城市群的经济发展水平有较大提升,生态保护建设进展较为缓慢,二者耦合度波动上升。（2）上游城市群的协调度低于中下游,整体协调度提升至良好协调。（3）存在从经济发展滞后型向生态保护滞后型的转变。（4）各城市群的协调度存在关联效应。（5）影响耦合的机制和民生发展与对外开放、科技创新与产业发展、绿色发展与农业建设、基本公共服务体系等密切相关。

Spatio-temporal pattern and mechanism analysis of coupling between ecological protection and economic development of urban agglomerations in the Yellow River Basin

By studying the strategic background of the Yellow River Basin and the development plan of urban agglomerations in the basin, this paper constructs an index system for evaluating ecological protection and economic development that can be applied to a comparative study of urban agglomerations. Based on the index system, this paper analyzes the spatio-temporal characteristics and driving mechanism of the coupling coordination between ecological protection and economic development of seven major urban agglomerations in the basin from 2007 to 2019 by using the coupling coordination degree model, spatial autocorrelation and geographic detectors. The results show that: (1) During the study period, the economic development level of the seven major urban agglomerations has been greatly improved, the progress of ecological protection construction is relatively slow, and the coupling degree between them rises in a fluctuating manner. (2) The eco-economic coordination degree of the urban agglomerations in the upper reaches is lower than that of the middle and lower reaches, and the overall coordination degree is improved to a higher level compared with that of the development mode which was significantly unbalanced in the past. (3) Urban agglomerations in the Yellow River Basin have experienced a transformation from economic development lag to ecological protection lag. (4) The coordination degree between ecological protection and economic development of each urban agglomeration has correlation effect. (5) The coupling mechanism is closely related to people's livelihood development and opening-up, technological innovation and industrial expansion, green development and agricultural construction, basic public service system and so on.
