| 摘 要： | 基于长江经济带9省2市2000～2017年数据,建立长江经济带城镇化与生态环境交互耦合协调发展评价体系,运用耦合协调模型和交互胁迫模型,探究二者的动态关系。结果表明:在时间序列上,2000～2017年,长江经济带的城镇化与生态环境之间的协调性呈现稳步上升态势,整体处于良好耦合协调阶段。研究期初,生态环境综合指数高于城镇化综合指数;研究期末,城镇化综合指数高于生态环境综合指数。在空间格局上,二者的协调发展态势存在由东部区域沿中西部区域下降的空间差异特征。长江经济带的城镇化与生态环境之间存在交互胁迫关系,演变状态符合双指数函数特征。长江经济带区域内各省市存在城镇化与生态环境动态耦合关系的空间分布不均衡,经济较发达地区城镇化水平较高,经济欠发达地区生态环境受恶化风险较大。

| Abstract: | There exists an extremely complex dynamic coupling relationship between urbanization and eco-environment, which indicates that urbanization has a strong coercing effect on eco-environment, and eco-environment has a lagged constraint force on urbanization. How to realize the coordinated development of urbanization and eco-environment has become a hot topic in recent years at home and aboard. This paper establishes the comprehensive evaluation index system on urbanization and eco-environment evaluation system, based on the data of nine provinces and two cities of the Yangtze river economic belt from 2000 to 2017. The results show that in terms of time series, the coordination between urbanization and ecological environment in the Yangtze river economic belt has been on a steady rise from 2000 to 2017, and the whole area is in a good coupling and coordination stage. At the beginning of the study, the comprehensive index of ecological environment was higher than the comprehensive index of urbanization. At the end of the study, the comprehensive index of urbanization was higher than the comprehensive index of ecological environment. In the spatial pattern, the coordinated development trend of the two has the spatial difference characteristic of decreasing from the eastern region to the central and western regions. There is an interactive stress relationship between urbanization and ecological environment in the Yangtze river economic belt. The spatial distribution of the dynamic coupling relationship between urbanization and ecological environment exists in all provinces and cities in the Yangtze river economic belt region. The urbanization level is higher in economically developed areas, while the ecological environment in economically less developed areas is at greater risk of deterioration. |
