郑州国家中心城市高质量发展与生态环境耦合协调度研究

Research on the Coupling Coordination Degree of High-quality Development and Ecological Environment of Zhengzhou National Central City

为了探究郑州国家中心城市高质量发展与生态环境发展的相互关系问题,结合城镇化发展阶段和引入压力—状态—响应(PSR)模型来构建复合评价指标体系,运用耦合协调度模型定量测度2016—2021年两系统的综合水平以及耦合协调关系。研究结果显示:整体上来看,高质量发展指数和生态环境指数总体呈现增长态势,但在2020年出现大幅度下降;两系统的耦合协调度呈现稳定上升的态势,从低度协调耦合升级为高度协调耦合,但距离极度协调耦合还存在一定的距离,需要采取措施加以强化。

In order to explore the relationship between the high-quality development of Zhengzhou’s national central city and the development of the ecological environment,combined with the development stage of urbanization and the introduction of the pressure-state-response(PSR)model to construct a composite evaluation index system,the coupling coordination degree model was used to quantitatively measure the comprehensive level and coupling coordination relationship of the two systems from 2016 to 2021.The research results show that the high-quality development index and the ecological environment index on the whole show an overall growth trend,but they will dropped significantly in 2020;the coupling coordination degree of the two systems shows a steady upward trend,from a low degree of coordination to a high degree of coordination.There is still a certain distance from high-quality coordinated coupling,and measures need to be taken to strengthen it.
