中国城市群拟态人居环境耦合协调度时空分异

Spatio-Temporal Differentiation of Coupling Coordination Degree of Pseudo Human Settlements in China’s Urban Agglomerations

摘要: 随着互联网的飞速发展，拟态人居环境应运而生，城市群亟需适应数字化与智能化转型。本研究聚焦中国19个城市群，旨在探究拟态人居环境协调发展的时空格局及障碍因素。本文创造性地构建了拟态人居环境的理论框架，运用耦合协调度模型、重心–标准差椭圆及障碍度模型等研究方法，得出以下结论：(1) 耦合协调度呈现“高耦合–低离散、低协调–高离散”的特征，耦合协调度类型共有6种，失调型占据主导，类型演变呈现出“失调主导–协调萌芽–协调扩展”的三阶段特征；(2) 从时间维度看，以2015年为时间节点，耦合协调度先快速增长、后波动下降并渐趋稳定；(3) 从空间维度看，耦合协调度东高西低并伴随“核心–边缘”分化格局，空间集聚与重心南移特征突出。本研究通过剖析中国城市群拟态人居环境的演变机制，丰富数字时代人居环境研究的理论内涵，为人居地理学研究提供新视角，拓展城镇化理论中“人–地–技术”交互关系的研究维度，同时有助于推动城市高质量发展，建设创新、宜居、文明、智慧的现代化人民城市。

Abstract: With the rapid development of the Internet, pseudo human settlements have emerged, and urban agglomerations must urgently adapt to digital and intelligent transformation. This research focuses on 19 China’s UAs and aims to explore the spatio-temporal patterns and obstacles to the coordinated development of PHS. The study creatively constructs a theoretical framework for PHS and employs methods including the coupling coordination degree model, standard deviation ellipse, and obstacle degree model. Findings show: (1) The coupling coordination degree exhibits the overall characteristics of “high coupling-low dispersions, low coordination-high dispersion”. There are six types of coupling coordination, with disordered types dominating. The evolution of types shows three stages: “disorder prevalent-coordination emerges-coordination expands”. (2) Temporally, taking 2015 as the reference point, the overall trend shows rapid growth followed by fluctuations and declines, gradually stabilizing. (3) Spatially, it shows “east-high, west-low” and “core-periphery” patterns, with spatial agglomeration and a southward center of gravity shift. This study enriches the theoretical content of human settlements research in the digital age, provides new perspectives for human settlements geography, and expands the research dimension of the “human-land-technology” interaction in urbanization theory. Meanwhile, it contributes to promoting high-quality urban development and the creation of innovative, livable, civilized, and smart modern cities for the people.
