东北三省城市拟态与现实人居环境时空耦合协调特征与机制

单一形态的现实人居环境研究,不能合理诠释人地关系地域系统下日益变化的人居环境现象。目前,不同形态人居环境相互作用的理论基础、实践探索以及科学决策等问题并不清晰。建构城市拟态与现实人居环境耦合协调的理论框架,运用耦合协调模型、空间趋势分析、地理探测器等实证分析2011—2017年东北三省34个地级市耦合协调的时空规律,并对其影响因子和驱动机制进行探讨。结果表明：① 东北三省城市耦合度总体呈现出上升的态势,具有相对明显的阶段特征;空间上形成双核与单中心并存的格局,并由分散的团状向“T”型团带状空间格局演变;② 协调度总体处于濒临失调状态,协调互动稳步向高级别发展演变,中级协调占据一定地位,高级协调开始出现;协调度的核心极化空间格局特征明显,四大城市主导着东北三省整体的协调互动级别;同时形成省内“极化与均衡并存”、省际“北低南高”、整体“中心—边缘—低洼地”等区域差异的空间格局;协调度整体呈现出东西方向的“中间凸起、两端略低的倒‘U’型”与南北方向上的“南高北低”的空间趋势特征;③ 拟态与现实人居环境耦合协调发展是多种因子综合作用的结果,其中社会经济发展是主导性驱动,“人”是本底性驱动,娱乐系统是新兴性驱动,社交系统是重要的媒介性驱动。

Spatio-temporal coupling coordination and driving mechanism of urban pseudo and reality human settlements in the three provinces of Northeast China

The study of a single form of the reality human settlements cannot reasonably explain the ever-changing human settlements phenomenon under the human-land relationship regional system. At present, the theoretical basis, practical exploration, and scientific decision-making of the interaction between different forms (reality, pseudo, and imagery) of human settlements are not clear. To construct the theoretical framework of the coupling coordination of urban pseudo and reality human settlements, this paper uses the coupling coordination model, spatial trend analysis, geographical detector and other empirical analysis methods to analyze the space-time law of coupling coordination in the three provinces of Northeast China from 2011 to 2017, and discusses its influencing factors and driving mechanism. The results show that: (1) the coupling shows a rising trend, with relatively obvious stage characteristics; a dual-core and single-center coexistence pattern is formed in space, and the spatial pattern evolves from scattered clusters to "T"-shaped clusters and bands; (2) Overall coordination is on the verge of imbalance, coordination and interaction have steadily evolved to a high level, intermediate coordination has occupied a certain position, and high-level coordination has begun to emerge; The core polarization spatial pattern of the degree of coordination is obvious, the four major cities dominate the overall level of coordination and interaction in the three provinces; At the same time, the spatial pattern of regional differences, nemely, "coexistence of polarization and balance" within the province, "lower in the north and higher in the south" across the study area, and "center-periphery-low lands" for the whole region, will be formed; The overall coordination shows the spatial trend characteristics of "high in the middle and low at both ends" in the east-west direction and "higher in the south and lower in the north" in the north-south direction; (3) the coupling and coordinated development of pseudo and reality human settlements is the result of comprehensive factors, among which social and economic development is the dominant driver, "human" is the background driver, entertainment system is the emerging driver, and social system is the important media driver.
