摘要:

针对现有文献对于城市内部多中心空间结构演化过程中的时间异质性探讨不足的问题,本研究基于1 km格网人口数据,采用相对最小阈值法测度2005—2015年全国地级市城市内部形态多中心性,使用系统聚类算法对其时序演化模式进行归纳,并通过混合效应模型将时间异质性纳入到城市多中心性演化相关因素的探索中。研究发现:① 中国城市多中心结构在2010年前后基本形成;② 共识别了五种多中心的演化模式;③ 多中心性与区位特征、人口特征、经济水平、基础设施和城市规模显著相关;④ 中国城市多中心性演化在时间序列上呈现出差异性,符合扩散-聚合的规律,与经典城市结构理论相契合。研究发现及使用的相应方法有助于推进对于城市多中心性发展规律的进一步理解。

Abstract:

The existing research on the temporal heterogeneity across the urban-internal polycentric developments remains insufficient. To fill this research gap, we employed the relative minimum threshold approach to measure the intra-city morphological polycentricity in Chinese prefecture-level cities, 2005-2015, using the 1-km-grid population dataset. The hierarchical-cluster analysis was then adopted to induce the patterns of temporal variations in polycentricity. Finally, the mixed effect model is used to capture the temporal heterogeneity and explore the correlation factors of intra-city polycentricity during the focal period. The results showed that: (1) the multicenter structure of Chinese cities has been basically formed around 2010; (2) five evolution patterns were identified; (3) the urban-internal morphological polycentricity presented significant correlations with the geographic features, demographic characteristics, economic performance, infrastructures, and city size; (4) consistent with the classic urban structure theory, the evolution in urban China exhibited significant temporal variations and conformed to the diffusion-coalescence development pattern. The research findings and corresponding methodologies of the current research can help to advance the understanding of patterns of urban polycentric developments in urban China.
