西北地区城镇化与生态环境耦合协调度测度

The coupling coordination development between urbanization and ecological environment in northwest Chin

基于2005-2013年西北四省(区)的面板数据,利用耦合协调度模型揭示了西北四省(区)城镇化与生态环境耦合协调状态的演变特征,并通过回归模型分析了耦合协调度的影响因素。结果显示:随着城镇化水平和生态环境质量的提升,西北四省(区)均进入了城镇化与生态环境协调发展阶段,其城镇化与生态环境总体上呈现出互补互适的特征;由于城镇化水平的提升快于生态环境质量的改善,西北地区由城镇化滞后型转变为生态环境滞后型;在对耦合协调度的贡献中,生态环境的作用大于城镇化,影响较显著的子系统依次是生态水平、人口城镇化、社会城镇化、经济城镇化和生态响应。

Based on the northwest four provinces panel data from 2005 to 2013, using the Coupling Coordination Degrees Model, this essay reveals the temporal and special characteristics of the coupling coordination state between urbanization and ecological environment in this region. Through the regression model, this essay probes the main factors influencing the coupling coordination degrees. The main findings of this essay are as follow： With the improvement of urbanization and ecological environment in the northwest minority region, both systems are coordinated and jointly promote each other. The development of urbanization is significantly faster than the improvement of ecological environment, therefore, most provinces have changed from urbanization lag model into ecological environment lag model. The effect of ecological environment is greater than the effect of urbanization on the coupling coordination degrees. In addition, Subsystems with obvious influence are the ecological level, population urbanization, social urbanization, economic urbanization and ecology response, respectively.
