摘要
泛长株潭城市群空间结构具有城镇分布密度大且人口分布与城市分布相一致、城市分布交通指向性明显、交通网络比较发达、城市群空间联系较弱、首位城市带动作用不强等特点。借鉴国内外城市群空间结构发展的典型模式及其成功经验,根据泛长株潭城市群的实际,可采取强调"一点一核一心,五圈三轴"建设的反"K"字型模式对其空间结构进行优化整合,即重视核心城市长沙的建设,强调长株潭3市的联动发展,保留3市城乡结合部的中央绿心,打造五大城镇组群并强化三大轴线的辐射带动作用。
Using the typical mode and structural features of city clusters both at home and abroad for reference, the spatial structure of the pan-CZT city cluster was analyzed in this paper, in which the urban density theory, the sub-dimensional spatial structure theory of city clusters and the space interaction theory were used .Many features ofpan-CZT city clusters were shown, such as great urban density, the coincidence between population distribution and urban distribution, obvious directivity of city distribution along traffic lines, developed transport network, feeble links between city clusters, weak pulling effect of primate city ,etc. Therefore, the anti-＂K＂ space structure optimization model of pan-CZT was adopted to comply with the new trends in city clusters research and new requirements of building the ＂two-oriented society＂, which emphasized on constructing ＂1 point 1 core 1 center, 5 circles and 3 axises＂, i.e. the core city Changsha to be given a high status; linking the development of Changsha, limiting developments in Zhuzhou and Xiangtan, the green heart at the centre of the three cities to be reserved; the five major city groups to be constructed and the leading role of the three main axis to be strengthened.
