重庆山地城镇群网络结构的组织特征及评价研究--手机信令的视角

Research on the Organizational Characteristics and Evaluation of the Network Structure of Mountainous Town Groups in Chongqing-- The Perspective of Phone Signaling

文章通过手机信令数据分析重庆城镇体系中各城镇间的人流出行联系,反映城镇体系的等级结构和网络体系特征。首先,用手机信令数据分析城市间出行方式及通勤的人流出行联系,以真实的人流出行联系反映城市之间的相互作用,从联系流量、联系流向、对中心城的依存度、首位度等各方面量化分析城镇体系特征。其次,以直辖市重庆为案例,基于手机信令数据,分别从主城区与区县、区县与区县两个层次分析结构特征,并与上位规划对比,评估现状城镇发展情况。研究表明,重庆城镇间抱团发展现象明显,层次鲜明,形成主城区、万州、永川、涪陵、黔江和铜梁六个不同层级的区域中心。

This paper analyzes the outbound connections between cities and towns in the urban system of Chongqing through mobile phone signaling data, which reflects the hierarchical structure and network system characteristics of the urban system. First, it uses mobile phone signaling data to analyze the full-city and commute outbound connections between cities, and reflect the interactions between cities with real outbound connections, and quantify the characteristics of the urban system from contact flow, connection flow, dependence on the central city, and priority and other aspects. Secondly, taking the municipality Chongqing as a case, based on mobile phone signaling data, this paper analyzes the structural characteristics between the main urban area and districts, and between districts and counties, and compares with the higher-level planning to evaluate the current urban development. Research shows that the development of clans in Chongqing’s cities and towns is obvious and the levels are distinct, forming six different levels of regional centers in the main urban area, Wanzhou, Yongchuan, Fuling, Qianjiang, and Tongliang.
