资源型城市城镇化与生态环境耦合关系研究——以大同市为例

A Study on the Coupling Relationship of Resource-based Cities between Urbanization and Ecological Environment——Taking Datong City as An Example

本文以大同市为例,基于2010—2019年统计数据,应用灰色关联模型对城市化与生态环境的耦合关系进行分析。结果表明2010—2019年大同市城市化与生态环境的灰色关联度均在0.60—0.71之间波动,相关程度较高。城市化与生态环境的耦合度由2010年的0.412逐年增加到2019年的0.512,意味着大同市注重生态环境建设,减轻城市发展对生态环境的压力,使得两者协调趋于良好。

Taking Datong City as an example,based on the statistical data from 2010 to 2019,this paper analyzes the coupling relationship between urbanization and ecological environment by using grey correlation model.The results show that the gray correlation degree between urbanization and ecological environment of Datong fluctuates between 0.60 and 0.71 from 2010 to 2019,with a high degree of correlation.The coupling degree of urbanization and ecological environment has increased from 0.412 in 2010 to 0.512 in 2019,which means that Datong pays attention to the construction of ecological environment,and reduces the pressure of urban development on the ecological environment,thus,the coordination tend to be positive.
