摘要
随着老龄化程度的不断加深,城市空间面临着新的压力,老年人的空间需求越来越被重视,对老年人流动空间的分析是实现“老年人友好”城市规划的重要基础。文章结合手机信令数据,采用复杂网络分析方法构建老年人流动网络,对老年人工作日与休息日的流动网络进行分析。研究发现:(1)工作日和休息日老年人流动网络具有相似性,两个网络规模不大、覆盖范围有限,均表现出了“中心-外围”的结构特征,其中工作日为双中心结构,休息日为单中心结构;(2)两个网络的核心节点主要集中在老城区,从类型看主要包括两类,一类是以村庄、安置区和老旧小区为主的街区,一类是以公园绿地为主的街区;(3)主城内的社团之间相互联系密切,主城与副城的社团、副城社团之间联系较弱,其中位于主城中的老城区内的社团内部老年人流动网络呈现出“多核心”的结构特点,位于3个副城区域的社团老年人流动网络则呈现出“单核心”特征。
As the degree of aging continues to deepen,urban space is facing new pressures,and the space needs of the elderly have been paid more and more attention.The analysis of the elderly flow space is an important basis for realizing the "elderly friendly"urban planning.In this paper,combined with themobile phone signaling data,the flow network of the elderly is constructed by using complex network analysis method,and the flow networks of the elderly on weekdays and weekends are analyzed.The results show that:The characteristics of the elderly flow space network on weekdays and on weekends are similar.The two networks are small in scale and limited in coverage,and both show the structural characteristics of "center-periphery",of which the weekday has a dual-center structure.The weekend is a single-center structure.The core nodes of the two networks aremainly concentrated in the old urban areas.From the perspective of the core node types,there aremainly two types:one is the block mainly composed of villages,resettlement areas and old communities,and the other is mainly composed of parks and green spaces.The associations in the main city are closely related to each other,but the link between the main city and the sub city is weak.Similarly,the association between the sub city and the sub city is also weak.The elderly flow network within the community in the old urban area of the main city presents the structural characteristics of "multi-core",while that in the three suburban areas presents the "single core" feature.
