滨海城市现实人居环境时空耦合格局研究

Research on the Spatio-Temporal Coupling Pattern of Real Human Habitat in Coastal Cities

摘要: 以我国的53个滨海城市为研究对象，基于2011年、2015年、2020年的中国城市统计年鉴、中国城市建设统计年鉴等多源数据，借助耦合协调度模型对“人类–居住–社会–支撑–环境”五大系统之间的相互联系及时空演变特征情况进行深入探讨并对我国滨海城市的现实人居环境时空耦合格局进行研究。结论如下：(1) 滨海城市现实人居环境时空耦合度整体比较稳定，处于磨合阶段或拮抗阶段；(2) 滨海城市现实人居环境耦合协调度整体呈现上升趋势，从轻度失调转向濒临失调；(3) 滨海城市耦合度与耦合协调度的分布呈现了非均匀性的特点，区域差异较大，整体呈现“中间高、两边低”鲜明的区域分异特征，环渤海(包括辽、津、冀、鲁)、长江三角洲(包括苏、沪、浙)和泛珠江三角洲(包括闽、粤、桂、琼)三大区域呈现出中部地区向两侧递减的“驼峰”式空间结构特征。

Abstract: Taking 53 coastal cities in China as the research object, based on the data of the Statistical Yearbook of China’s Urban Statistics, the Statistical Yearbook of China’s Urban Construction and the statistical yearbook of each city in 2011, 2015 and 2020, with the help of the coupling coordination model, the five major “human-residential-social-support-environment”. The interconnection between systems and the characteristics of time-space evolution are discussed in depth, and the space-time coupling pattern of the real human habitat of coastal cities in China is studied. The conclusion is as follows: (1) The overall space-time coupling of the real habitat environment in coastal cities is relatively stable, in the running-in stage or antagonistic stage; (2) The overall coupling and coordination of the real human habitat in coastal cities shows an upward trend, from mild dislocation to near-dislocation; (3) The distribution of coupling degree and coupling coordination in coastal cities It presents the characteristics of non-uniformity, and the regional differences are large. The whole shows the distinct regional differentiation characteristics of “high in the middle and low on both sides”. The three regions around the Bohai Sea (including Liaoning, Tianjin, Hebei and Shandong), the Yangtze River Delta (including Jiangsu, Shanghai and Zhejiang) and the Pan-Pearl River Delta (including Fujian, Guangdong, Gui and Qiong) show the central region. The characteristics of the “hump” spatial structure that decreases to both sides.
