摘要
运用引力模型,对长江中游城市群空间相互作用展开了实证研究。通过对城市综合实力及城市间交通距离得分进行计算,最终得到了长江中游城市群空间相互作用值,在此基础上,从城市群综合实力及空间相互作用倾向度两个方面对长江中游城市群空间相互作用的影响因素及机理展开了分析研究。综合分析得出:城市群空间相互作用水平较低,城市与城市群的空间相互作用水平差异显著;城市群空间相互作用网络形态主要呈放射状,武汉、长沙在区域中的中心性作用明显;武汉都市圈与环长株潭城市群发育较为成熟,环鄱阳湖城市群发育水平较低;三个二级城市群之间武汉都市圈与环长株潭城市群相互作用水平最高,沿京广铁路—京珠高速形成了一条较高水平的空间相互作用带。
The gravity model was used in the empirical research on spatial interaction of the urban agglomeration in the middle reaches of the yangtze river. By the calculation of city＇s comprehensive strength and inter city＇s traffic distance, this paper finally got the scores in the spatial interaction of the urban agglomeration in the middle reaches of the yangtze river. On this basis, the affecting factors and mechanism of spatial interaction of the urban agglomeration in the middle reaches of the yangtze river was analysed from two aspects： comprehensive strength of the urban agglomeration and orientation of spatial interaction. On the basis of comprehensive analysis, it was concluded that the level of the urban agglomeration＇s spatial interaction was low and the differences in the level of spatial interaction between each city and the urban agglomeration was significant, the spatial interaction＇s network of the urban agglomeration mainly was radial, Wuhan and Changsha＇s central role in the area was obvious, the Wuhan city circle and the ring of Changsha Zhuzhou Xiangtan city group was relative mature compared with the Poyang Lake city group, and that between this three second level city groups, the level of spatial interaction between the Wuhan city circle and the ring of Changsha Zhuzhou Xiangtan city group was highest,and a belt of high levels＇ spatial interaction came into being along the Beijing Guangzhou Railway -the Beijing Zhuhai expressway.
