摘 要: | 摘要:以“空间分布-空间组合”为研究框架,采用因子分析和GIS技术相结合的方法,对中部地区城市体系空间结构进行特征分析,结果表明:(1) 中部地区城市空间布局模式为凝聚型分布。(2) 城市空间分布的区域差异性及交通指向性特征显著,形成分别以武汉、长沙、郑州、合肥以及太原为核心的城市分布集聚区,环鄱阳湖地区城市节点发育弱。(3) 中部地区已形成以1个核心城市,3个区域中心城市,21个区域次中心城市以及55个地方性城市所构成的城市体系。(4) 京广线和长江是中部地区最重要的2条城市发展轴,陇海、京九和浙赣则较弱。(5) 城市域面发展水平的区域分异特征明显。基于上述结论,文章最后进一步探讨了长江中游各城市群进行整合发展的必要性。

Study on the Spatial Structure of Urban System in Central China |
| |
Abstract: | Abstract: Based on the framework of “Spatial distribution, Space combination”, the paper analyses the features of the spatial structure of prefecture-level and above cities in Central China by SPSS and GIS. The results are as follows: (1) Spatial distribution of urban system in central China belongs to the cluster pattern. (2) The spatial distribution of cities shows significant characteristics on regional difference and traffic directivity, five cities’ agglomerations have formed respectively with the cores of Wuhan, Changsha, Zhengzhou, Hefei and Taiyuan while the development degree of cities is still low in Poyang Lake Region. (3) One core city, three regional center cities, 36 secondary regional center cities and 38 local cities compose the urban system of central China. (4) There are two urban development axes along Beijing-Guangzhou Railway and Yangtze River which are most important in Central China, however, the development along Lianyungang-Lanzhou and Beijing- Kowloon and Hangzhou- Zhuzhou Railways is weaker than those. (5) There exists significant differentiation among the developmental level of urban region. Based on the above conclusion, it is necessary for us to explore the integrated development at urban agglomeration in the middle reach of Yangtze River. |
