以长株潭城市群为研究对象,将功能互补与水平联系两种关联机制作为切入点,借助城市流理论以及GIS分析技术,对长株潭网络城市的时空格局进行分析。结果表明:1在空间方面,从功能互补机制看,长株潭三市整体总外向功能量为正值,内部因城市功能不同而相互辐射与承接;从水平联系机制看,节点城市间的水平联系表现出层次性、经济性、网络性特征,虽然经济空间略不均衡,但网络结构初步成型。2在时空演进方面,节点城市间功能互补镶嵌作用逐渐显著,区域网络化趋势明显。据此,长株潭具备网络城市构建的良好条件,并提出主要城市与一般城镇需协同发展,使各县市能够通过高效智能的城市网络进行有效联结。
Taking Changsha-Zhuzhou-Xiangtan urban agglomeration as the research object, this paper takes two correlative mechanisms of functional complementation and horizontal contact as starting points, and analyzes the spatial and temporal patterns of Changsha, Zhuzhou and Xiangtan urban agglomerations based on the theory of urban flow and GIS analysis. The results show that: 1 In terms of space, from the perspective of functional complementarity, the overall outward power of the three cities in Changsha, Zhuzhou and Xiangtan is positive, and their internal radiations and undertaking depend on each other’s urban functions. From the perspective of horizontal connection mechanism, the level of inter- The relationship shows the characteristics of hierarchy, economy and network. Although the economic space is slightly uneven, the network structure is initially shaped. (2) In terms of temporal and spatial evolution, the function of complementary mosaic between nodes in cities becomes more and more obvious, and the trend of regional network is obvious. Accordingly, Changsha, Zhuzhou and Xiangtan have good conditions for building an online city, and propose that coordinated development should be made between major cities and ordinary towns so that all counties and cities can effectively connect through an efficient and intelligent urban network.
