沈阳市居住—就学网络空间结构研究

Study on the Spatial Structure of Residence-School Network in Shenyang

基于实际发生的小学生就学流研究城市网络空间结构是一种全新思路。利用2018年沈阳市手机信令数据,运用社会网络分析与优势流分析等方法测度沈阳市居住—就学网络的空间结构特征。研究表明:①沈阳市居住—就学网络结构呈现"多中心层级化"结构特征,形成以太原街街道为主导,风雨坛街道、贵和街道等7个街道为次级主导,西塔街道、皇城街道等30个街道为控制节点,其他街道为从属的层级结构;②七路街道—贵和街道—太原街街道—风雨坛街道是沈阳市居住—就学网络结构主轴线,辽河街道—黄河街道—西塔街道—太原街街道是居住—就学网络结构次轴线;③"一主三副多组团"是沈阳市居住—就学空间结构的基本格局;④沈阳市小学生就学行为具有明显的空间依赖性,行政区划对就学行为具有重要影响。

This study provides a new way to analyze the urban network structure based on the actual schooling flow of primary school students.Using the mobile signaling data of Shenyang in 2018,this paper measures the spatial structure characteristics of Shenyang’s residence-school network using social network analysis and dominant flow analysis.The results indicate that:1)Shenyang’s residence-school network has a polycentric hierarchical structure which is consist of the dominant area(Taiyuan Neighborhood),the subdominant areas(Fengyutan neighborhood,Guihe Neighborhood),the control nodes(Xita Neighborhood,Huangcheng Neighborhood)and other Neighborhoods as subordinate.2)Qilu Neighborhood-Guihe Neighborhood-Taiyuan Neighborhood-Fengyutan Neighborhood is the primary axis of the residence-school network structure in Shenyang,while Liaohe Neighborhood-Huanghe Neighborhood-Xita NeighborhoodTaiyuan Neighborhood as the secondary axis.3)The basic structure of Shenyang residence-school indicates"one main group,three subgroups and multi groups"characteristics.4)It shows spatial dependent on the schooling behavior of primary school students,and the administrative division plays a vital role in schooling behavior.
