Study on the Spatial Structure of Urban System in Central China

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:①Spatial distribution of urban system in central China belongs to the cluster pattern.②The 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.③One core city, three regional center cities, 36 secondary regional center cities and 38 local cities compose the urban system of central China.④There 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.⑤There 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.
