城市群城镇化与生态环境的耦合与响应关系——以山东半岛城市群为例

The coupling and responsive relation between the urbanization of urban agglomeration and the ecological environment——taking Shandong peninsula urban agglomeration as an example

运用耦合协调度模型对山东半岛城市群17市的城镇化与生态环境耦合度特征展开分析,并运用响应指数和响应度模型对17市城镇化的生态环境响应关系进行实证研究。研究结果表明:(1)山东半岛城市群17市城镇化与生态环境的总体协调发展水平较低,根据耦合协调度测算结果,山东半岛城市群17市城镇化与生态环境耦合协调关系可划分为协调、低度协调、中度失调三种类型;(2)济南、青岛、东营和威海4市城镇化的生态环境响应指数为"负响应",其城镇化水平的提升对生态环境的改善具有积极作用,其余城市响应指数为"正响应"且相对稳定。

By using the model of coupling coordination to analyze the coupling characteristics of urbanization and ecological environment in 17cities of Shandong peninsula urban agglomeration,we have studied the ecological environment response relationship of 17cities with the response index and response model.The results show that(1)the overall coordinated development level of urbanization and ecological environment of Shandong peninsula urban agglomeration is low,and according to the results from the method of coupling coordination,the coupling coordination between urbanization and ecological environment can be divided into three types:coordination,low degree coordination and severe disorder;(2)the eco-environmental response index of urbanization in Jinan,Qingdao,Dongying and Weihai is“negative response”,and its improvement of urbanization level plays an active role in improving the ecological environment,and the other urban response indexes are“positive response”and relatively stable.
