辽宁省城市人居环境系统耦合协调度时空格局演变及驱动力研究

人居环境系统内部的耦合协调是保证人居环境均衡发展的基础。基于“人类-居住-支撑-自然-社会”5个子系统,构建人居环境系统耦合协调发展评价指标体系,将2个系统间的容量耦合模型扩展运用到人居环境5个子系统中,综合熵值法、GIS空间分析以及地理探测器对辽宁省2005~2016年人居环境系统耦合协调度的时空演化特征与驱动力进行探讨,阐述人居环境系统内部协调性。研究表明:①2005~2016年辽宁省人居环境系统内部的耦合度与耦合协调度整体呈缓慢浮动上升趋势;②辽宁省人居环境耦合协调度呈分散格局,并且呈现从中间向两侧递减的“屋脊”式格局和“双核结构”;东西方向上,空间演变趋势由倒U型逐渐向一字型演变,南北方向上由斜线型向“L”型演变。③全省出现了中耦合低协调区、中耦合过渡协调区、高耦合低协调区、高耦合过渡协调区、高耦合高协调区5种类型区。④空间分异驱动力主要包括人的需求、经济发展、住房、互联网发展等。

The Spatio-temporal Pattern Evolution and Driving Force of the Coupling Coordi-nation Degree of Urban Human Settlements System in Liaoning Province

Coupling coordination within the human settlements system is the basis for ensuring a balanced development of the human settlements. This paper expounds the internal coordination of the human settlements system and discusses the spatial and temporal distribution and driving force of the coupling and coupling coordination degree of human settlements in Liaoning Province, China. This paper builds the evaluation index system of the coupled development of human settlements system based on the five subsystems of ‘human-living-support-nature-society’. The coupling model between two systems is extended to five subsystems of human settlements. The entropy method and GIS spatial analysis methods are used to analyze the spatial-temporal evolution characteristics of coupling coordination degree of human settlements system in Liaoning Province from 2005 to 2016. The research shows that: 1) From 2005 to 2016, the coupling degree and coupling coordination degree of the human settlements system in Liaoning Province showed a slow upward trend. There is a difference in the degree of coordination between cities. The high value areas of coupling coordination degree includes Shenyang and Dalian. The median area of coupling coordination degree includes Anshan, Fushun, Benxi, Dandong, Jinzhou, Yingkou, Liaoyang, Panjin, Tieling, Chaoyang and Huludao. The coupling coordination degree low value area includes Fuxin. 2) The coupling coordination degree of human settlements in Liaoning Province is in a dispersed pattern which presents a ‘roof ridge’ pattern and a ‘dual-core structure’ that decrease from the middle to the sides. In the east-west direction, the spatial evolution trend gradually evolves from the inverted the ‘U’ shape to the‘—’shape, and the north-south direction changes from the tilted line type to the ‘L’ type. The coupling coordination degree between Shenyang and Dalian has been in the top two, far higher than other cities, as a dual core to lead the coordinated development of the human settlements system in Liaoning Province. 3) There are five types of zones: medium coupling-low coordination zone, medium coupling-transition coordination degree zone, high coupling-low coordination degree zone, high coupling-transition coordination degree zone and high coupling-high coordination degree zone. 4) We use geographic detector to explore the driving forces of the coupiling coordination within the human settlements system. The spatial differentiation driving force mainly includes people's needs, economic development, housing and internet development. People's needs are the basis for the coordinated development of the human settlements system. Economic development is the main driving force, and housing is a tool for coordinated development. However, the development of the Internet is a new driving force for the coordinated development of the human settlements system.
