【摘要】：城市群日益成为我国人口集聚和城镇化发展的重要载体,2015年4月《长江中游城市群发展规划》的提出标志着长江中游城市群建设正式上升为国家发展战略。基于2014年长江中游城市群人口和城镇化格局现状分析,采用湘鄂赣3省第四、五、六次人口普查数据,分析了1990~2010年长江中游城市群人口与城镇化格局的空间变化。研究发现:(1)1990~2010年,长江中游城市群人口分布不均衡,武汉、长沙、南昌3大省会城市一直是人口的主要集中地,人口集聚水平不断提升,但城市群整体的人口集聚水平有所下降,人口分布的空间格局呈现出由单核心结构向多核心结构的发展趋势;(2)人口"镇"化是长江中游城市群城镇化发展的主要驱动力,城镇化水平经历了由以长江为界北高南低分布向沿长江、京九和浙赣沿线地区分布的发展过程,形成了多核心结构的城镇化格局;(3)对比人口分布与城镇化格局的演变过程,反映出人口集聚度对城镇化格局的形成有着重要影响,但区域城镇化同时受到经济发展水平、工业化水平、基础设施等多种因素影响,其格局变化更加复杂、显著。
[Abstract]:Urban agglomeration has increasingly become an important carrier for the development of population agglomeration and urbanization in China. The development plan of urban agglomeration in the middle reaches of the Yangtze River in April 2015 marks the formal rise of the construction of urban agglomeration in the middle reaches of the Yangtze River into a national development strategy. Based on the analysis of the population and urbanization pattern of the urban agglomeration in the middle reaches of the Yangtze River in 2014, the spatial changes of the population and urbanization pattern of the urban agglomeration in the middle reaches of the Yangtze River from 1990 to 2010 were analyzed by using the data of the fourth, fifth and sixth censuses in the three provinces of Hunan, Hubei and Jiangxi. The results show that: (1) from 1990 to 2010, the population distribution of the urban agglomeration in the middle reaches of the Yangtze River is uneven. Wuhan, Changsha and Nanchang have always been the main centers of population concentration, and the level of population agglomeration has been improving. However, the population agglomeration level of urban agglomeration as a whole has decreased, and the spatial pattern of population distribution has shown a development trend from single-core structure to multi-core structure. (2) the urbanization of urban agglomeration in the middle reaches of the Yangtze River is the main driving force of urbanization in the middle reaches of the Yangtze River. The level of urbanization has gone through the process of distribution along the Yangtze River, Jingjiu and Zhejiang and Jiangxi along the north, south and low distribution along the Yangtze River, Jingjiu and Zhejiang and Jiangxi provinces. The urbanization pattern of multi-core structure has been formed. (3) comparing the evolution process of population distribution and urbanization pattern, it shows that the degree of population agglomeration has an important influence on the formation of urbanization pattern, but regional urbanization is affected by the level of economic development and industrialization at the same time. Infrastructure and other factors affect its pattern change is more complex and significant.
