基于手机信令数据的城市空间结构研究——沈阳城市职住状况分析与评价

Research on Urban Spatial Structure Based on Cell Phone Signaling Data:Job-Housing Analysis and Evaluation in Shenyang City

本文以沈阳为例,利用手机信令大数据作为数据源,提取现状岗位布局和职住空间联系信息,从居民职住的静态分布与动态联系两个维度,建立城市空间结构评价的技术框架,综合评价城市空间结构现状特征。以城市多中心结构发展理论为依据,对照沈阳规划提出的多中心结构发展目标,判断城市空间结构的发展阶段,挖掘城市现状问题,建立并提出城市从“形态多中心”向“功能多中心”发展的规划引导对策。

By taking Shenyang city as a case,this paper analyzed information of current job layout and job-housing connection based on the cell phone signaling data.We established a technical framework for urban spatial structure evaluation from the two dimensions of static job-housing layout and dynamic connection,and evaluated comprehensively the current status of urban spatial structure.On the basis of the theory of urban multi-center structure development and the goal of multi-center structure development posed by Shenyang City planning,we have figured out the development stage of urban spatial structure,explored current problems in the city,and finally,presented strategy to lead the transform of urban development from morphologic multi-center to functional multi-center.
