In the information age, digital information technology has gradually become a new quality of productivity to improve international competitiveness, and the status and importance of the pseudo human settlements(PHS) constructed by digital and information has been increasing in the human settlements(HS) system. In this context, exploring the coupling coordination of the internal systems of the PHS provides a theoretical basis for promoting the comprehensive improvement of the quality of the HS in the urban agglomerations, provides a theoretical reference for rationally interpreting the new type of human-land relationship in the information age, and provide a new perspective for the study of the human settlements geography. Currently, research on PHS is in its nascent stages, therefore, we construct a theoretical framework for the coupling coordination of the "three states" of the HS, takes the internal system of PHS as the entry point, empirically analyze the spatiotemporal characteristics of the PHS coupling coordination degree within urban agglomerations in eastern China and the driving factors by using the coupling coordination degree, spatial autocorrelation, the center of gravity and the ellipse of the standard deviation, and geo-detector models. Research shows: (1) Time course: exhibits an upward "inverted L" trend. (2) Spatial pattern: exhibits a general spatial pattern of "high in the north and low in the south". (3) Spatial correlation: shows a spatially positively correlated clustering trend. (4) Spatial evolution: demonstrates a decentralized pattern of migration from the northeast to the southwest, indicating that the coupling coordination grows faster in the southwest than in the northeast. (5) Driving factor: the development of coupling coordination degree of PHS results from multiple factors and systems. This research provides theoretical support for promoting the comprehensive improvement of the quality of PHS in the urban agglomerations in eastern China, and offers scientific reference for the construction of PHS in other regions of China.
在信息时代，数字信息技术已逐渐成为提升国际竞争力的一种新的生产力要素，数字与信息构建的虚拟人居环境在人居环境系统中的地位和重要性日益提升。在此背景下，探究虚拟人居环境内部系统的耦合协调性，可为推动城市群人居环境质量的全面提升提供理论依据，为合理阐释信息时代新型人地关系提供理论参考，为人居地理学研究提供新视角。目前，虚拟人居环境研究尚处于起步阶段，因此，我们构建了人居环境“三态”耦合协调的理论框架，以虚拟人居环境内部系统为切入点，运用耦合协调度、空间自相关、重心及标准差椭圆和地理探测器模型，实证分析中国东部城市群虚拟人居环境耦合协调度的时空特征及驱动因素。研究表明：（1）时间历程：呈向上的“倒L”型趋势。（2）空间格局：呈现“北高南低”的总体空间格局。（3）空间相关性：呈现空间正相关集聚趋势。（4）空间演变：呈现由东北向西南的分散式转移格局，表明西南地区的耦合协调度增长快于东北地区。（5）驱动因素：虚拟人居环境耦合协调度的发展是多种因素和系统作用的结果。本研究为推动中国东部城市群虚拟人居环境质量的全面提升提供了理论支撑，为中国其他地区虚拟人居环境建设提供了科学参考。
