摘要: 长江中游地区作为我国东中西部发展的传导区,是促进中部崛起的重要着力点和推进新型城镇化的重点区域,探究长江中游城镇化与生态环境的协调发展,为长江中游新型城镇化高质量发展提供参考。以长江中游为研究区域,构建城镇化与生态环境评价指标体系,利用耦合协调度模型,分别从长江中游整体、城市群之间、城市群内外部以及市域多个尺度,定量测度2005年、2010年、2015年、2017年长江中游城镇化与生态环境耦合协调度的时空格局特征,并在此基础上,采用GeoDa软件对长江中游城镇化与生态环境协调发展度进行全局和局部自相关检验。研究表明:1)长江中游整体城镇化与生态环境发展水平不断上升,耦合度始终保持在拮抗阶段,协调度从初级失调向初级协调转变,2017年长江中游整体协调度为0.53;2)长江中游4个城市群城镇化发展水平稳步提升,生态环境发展水平波动较大,2017年,除长株潭城市群协调度达到0.6,进入中度协调之外,其余城市群仍为初级协调,各城市群内部与城市群外部协调度为0.57~0.62,差异较小;3)市域城镇化与生态环境的耦合度和协调度具有空间差异,中心城市有先发展优势;4)国家政策支持、产业转型、地方发展是长江中游地区城镇化与生态环境协调度不断提升的根本原因;5)协调度空间差异主要集中在安徽和湖北,高高集聚区主要在江淮城市圈东部,低低集聚区逐渐减少至零。长江中游城镇化与生态环境的耦合协调发展程度不断上升,但其发展水平仍然较低,区域发展差异较大,实现长江中游城镇化高质量发展仍有较长的路要走。

Abstract: The middle reach area of the Yangtze River is the transmission area for development of eastern, central and western China. It is also a key area in promoting new urbanization. Research on its coupling coordinated development of urbanization and ecological environment can provide references for the high-quality development of new urbanization in the middle reach of the Yangtze River. This paper establishes an evaluation index system of urbanization and ecological environment, and uses coupling coordinated model to study its temporal-spatial pattern of coupling coordination between urbanization and ecology in the middle reach of the Yangtze River in 2005, 2010, 2015 and 2017 at the scales of the entire middle reach of the Yangtze River, among city clusters, internal and external city clusters and citywide. GeoDa is used to test the overall and local auto-correlation. The results show a growing urbanization and ecological environmental level with coupling degree at antagonistic stage and coordination degree in the transition from preliminary imbalance to preliminary coordination. The overall coordinated degree of middle reach of the Yangtze River is 0.53. Urbanization is continuously rising among the four city clusters, with a fluctuated ecological environmental level. All city clusters are at a preliminary coordination in 2017, except Changsha-Zhuzhou-Xiangtan city cluster whose coordination reaches 0.6, a medium coordination. Both internal and external coordination of city clusters are from 0.57 to 0.62, which is a small gap. Spatial difference exists in coordination and coupling of city wide urbanization and ecological environment, with central cities being of prior-developing advantages. The rising coordination is mainly contributed by state supportive policies, industrial transformation, and local development. Spatial difference of coordination is mainly concentrated in Anhui and Hubei. High-high concentrating area is the eastern Jiang-Huai city cluster, and low-low is almost none. This paper concludes that the coupling coordinated development of urbanization and ecological environment in middle reach of the Yangtze River is growing but relatively low, with regional gaps. There is still a long way to realize the high-quality development.

Key words: urbanization, ecological environment, coupling coordination, middle reach of the Yangtze River
