摘要: 为了探寻发达省份内城市间相互作用的时空特征,该文以浙江省为样本单元,选取2005、2010年和2015年3个时间截面,采用反距离权重法和空间插值手段,从城市流强度视角展开了实证分析。结果表明:(1) 城市间的联系在不断加强,期间城市流强度值随时间的推移而整体得到提升,空间上由初始的“中心点”通过发展扩散向“中心域”转变,中心城市的辐射带动作用开始发挥成效。(2)结构上呈现出相对稳定的北高南低的分布格局,以杭州市为龙头,宁波为副核心,温州、绍兴、舟山为重要节点的多中心城市网络结构雏形初步形成。(3) 城市流强度的空间分异特征分析明显,但分异程度有了些许的改善,侧面说明空间上由初始的“中心点”通过发展扩散向“中心域”转变的基本观点。最后就浙江省如何加强省内城市间“流”的规模性、区域协调性和可持续性展开了讨论。

Abstract: In order to explore the spatial and temporal characteristics of the interaction among the cities in developed province, this paper takes Zhejiang Province as the study sample, and from the perspective of city flow intensity makes an empirical analysis from 2005 to 2015 by using the inverse distance weighting method and the spatial interpolation method. The results show that: (1) the inter-city linkages are constantly strengthening. During the period, the strength of urban flow intensities has been enhanced as a whole over the time. From the initial "center point" to the "center area", the central city's radiation-led role has begun to play. (2) It shows a relatively stable distribution pattern with “North being high and South being low” from spatial structure perspective, and a multi-center city network that takes Hangzhou City as a leader, Ningbo City as a deputy core, and Wenzhou City, Shaoxing City and Zhoushan City as important nodes is initially formed. (3) The spatial differentiation of urban flow intensities is obvious, but the degree of differentiation has been slightly improved, which is reflected by the basic idea of the spatial transformation from the initial “single center” to the "center region" through the development and diffusion. In the end, the paper discusses how to strengthen the scale, regional coordination and sustainability of the “flow” among cites of Zhejiang Province.
