中原经济区城镇空间结构优化重组研究

Reconstruction of Urban Spatial Structure in Central Plains Economic Region

城镇空间组织是区域经济、社会发展的基础和骨架,在新型城镇化加速推进的背景下,中原经济区城镇空间结构优化具有重要的战略意义。采用非农业人口、GDP、第三产业产值、城镇空间距离等4个指标计算中原经济区各个基本地域单元(城镇)的综合实力指数,据此,重组中原经济区的城镇等级结构。采用经济隶属度、经济作用场强和中心城市可达性等三个指标,进行城镇组团的重组,并将30个城镇组团整合为郑州城市组群、洛阳城市组群、平顶山城市组群、邯郸城市组群和商丘城市组群。以城镇组团和城市组群为基础,沿主要交通线路构建京广和陇海两条一级城镇发展轴线,济南—郑州—重庆和合肥—郑州—太原两条二级城镇发展轴线,以及若干条三级城镇发展轴线。

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.
