摘要
研究目的:揭示不同时间截面城镇化与人居环境的动态耦合协调关系,为提升长江中游城市群可持续发展能力提供政策依据。研究方法:熵值法、耦合协调度模型和核密度估计。研究结果:(1)2005—2017年,长江中游城市群城镇化和人居环境水平总体上呈稳步上升的态势,空间上以武汉、长沙和南昌为峰值区域的“多中心”分布特征为主,且地域差异逐渐缩小;(2)城镇化与人居环境的耦合协调度则呈持续上升的态势,并从濒临失调逐步跨入初级协调阶段,空间分布上形成以武汉、长沙、南昌和新余为峰值区域,以荆州、孝感、咸宁、吉安等地为低值区域的分布格局,但地区差距逐渐缩小,有向片状分布发展的趋势。研究结论:研究期内长江中游城市群城镇化与人居环境指数逐年提升,并且城市化与人居环境的协调度在地区之间的差异逐渐缩小,存在明显的协同发展特征。
The propose of this paper is to reveal dynamic coupling and coordination relationship between urbanization and human settlement in different time sections,while it can provide policy references to improve sustainability of urban regions as well.Using the entropy method,coupling and coordination degree model and kernel density estimation,this paper investigated the temporal and spatial evolution trend,coordinating development of urbanization and human settlement of urban agglomerations in the middle reaches of the Yangtze River.The results show that:1)from 2005 to 2017,the level of urbanization and human settlement of urban agglomerations in the middle reaches of the Yangtze River has been steadily rising,forming the spatial distribution characteristics of“multi-centers”in the peak areas of Wuhan,Changsha and Nanchang,while the regional differences has gradually narrowed;2)the coupling degrees between urbanization and human settlement are in a rising trend,and shift from endangered disorders to primary coordination stage gradually,with Wuhan,Changsha,Nanchang and Xinyu at the peak area,Jingzhou,Xiaogan,Xianning and Ji’an at the low area.However,the regional gap is gradually narrowing and developing towards patchy distribution.In conclusion,during the study period,the urbanization and human settlement of urban agglomerations in the middle reaches of the Yangtze River increased year by year and the coordination degree gradually narrowed between different regions,showing an obvious characteristic of collaborative development.
