Reconstruction of Urban Spatial Structure in Central Plains Economic Region

Urban Spatial Organization is the foundation and skeleton of regional development in regional economy and society, in the background of fast development of new- urbanization, it has great strategic significance to establish the proper Urban Spatial structure of CPER(Central Plains Economic Region). By calculating the integrated strength indexes of all basic units of CPER based on four indexes: non- agricultural population, gross domestic product(GDP),tertiary industry product, spatial distance among towns, the urban system of CPER is reconstructed. And use three indexes:economic function field, economic membership degree and spatial accessibility of central towns to reconstruct all the urban into 30 urban groups, and integrate the 30 urban groups into Zhengzhou urban cluster, Luoyang urban cluster,Pingdingshan urban cluster, Handan urban cluster and Shangqiu urban cluster. Based on urban group and urban clusters,establish urban growing axes along traffic lines. There are two primary urban growing axes: JingGuang urban development axis and LongHai urban development axis, two secondary growing axes: Jinan- Zhengzhou- Chongqing urban development axis and Hefei-Zhengzhou-Taiyuan urban development axis, and some tertiary urban growing axes. In the same time, this article carries out the establishment of core urban group and its urban growing axis.
