长江中游城市群城市人居环境演变及驱动力研究

从生态、居住、公共服务、休闲环境等人居环境核心系统出发,综合运用AHP、地理探测器方法,对长江中游城市群城市人居环境时空演变过程、核心驱动力、驱动机理进行了系统研究。研究表明：① 城市人居环境综合质量格局呈现出西北部相对下降,东南部逐渐提升的过程,优质的人居环境逐步向环鄱阳湖地区及京广线沿线集中分布;② 生态环境质量格局逐渐呈现以襄阳-吉安连线为界,东侧质量显著优于西侧的格局。京广线沿线城市的居住、公共服务质量始终优于江西片区浙赣线沿线城市,但休闲环境质量则逐渐劣于江西片区浙赣沿线;③ 城市人居环境演变驱动力作用对象、程度、方向各异。其中经济发展、政府投入为城市人居环境演变的主导动力,社会群体收支为其内部关键动力,而土地供给与建设投资为现阶段次要动力,此外,城市规模通过集聚、催化作用推动城市人居环境的演变。

Evolution and Driving Force Detection of Urban Human Settlement Environment at Urban Agglomeration in the Middle Reaches of the Yangtze River

This article follows the main line of "setting up evaluation framework→describing the evolution process→detection of core dynamics→analytical driving mechanism". In the view of the core areas about urban human settlement, such as ecological, residential, public services, leisure, this article has made a systematic study on the evolution of urban human settlements at the urban agglomeration in the middle reaches of the Yangtze River, such as the spatial and temporal evolution process, the key factors and the driving mechanism, by using the methods about AHP, comprehensive fuzzy evaluation, Pearson correlation analysis. Research shows that: 1) urban human settlement comprehensive quality pattern shows a process that the quality of the northwest area has been relatively reduced and the quality of the southeast region has been gradually improved. High quality of urban human settlement gradually are concentrated in the Poyang Lake urban circle and the areas along the Beijing-Guangzhou line. 2) The pattern of ecological environment quality gradually is divided by Xiangyang-Ji’an line, and the quality of the eastern side of the dividing line is significantly better than that of the west side. The spatial and temporal patterns of living and public service environment are similar, and the leisure environment is opposite to that of the two. The main feature is residential quality and public service quality of the cities along the Beijing-Guangzhou railway line is always better than that of along the Zhejiang-Jiangxi railway line in Jiangxi, but the quality of leisure environment gradually has been inferior to the cities along the Zhejiang-Jiangxi in Jiangxi. 3) The evolution of urban human settlement is the result of multiple factors, and the object, degree and direction of each driving force are different. Among them, economic development, government investment is the dominant power of the urban human settlement evolution, the social group's revenue and expenditure is the key motive force, and the land supply and construction investment are the subordination driving forces of the present stage. In addition, the scale of the city promotes the evolution of the urban human settlement through the agglomeration and the catalysis.
