城市低收入社区生活圈公共服务设施配置空间分异研究--以武汉市为例

Spatial Differentiation of Public Service Facilities Configuration in Urban Low-Income Community Life Circle:A Case Study of Wuhan City

低收入人群受制于自身的支付能力和行动能力,能够享受到的城市服务质量与其所处的社区生活圈公共服务设施供给水平密切关联。论文以武汉市“三旧”改造空间数据、保障性住房分布数据为基础,识别出了武汉低收入社区生活圈,并在此基础上通过抓取互联网POI数据对其公共服务设施水平进行了评价。结果表明,低收入社区生活圈的公共服务设施水平与城市空间结构相关性高,在空间分布上呈现出圈层减弱、沿轴扩散的态势,并由此将低收入社区生活圈划分为6类。从空间分异机制来看,低收入社区生活圈公共服务水平优劣主要受到外部环境供给能力的影响,其中居住空间单元的变迁是基本动力,不同时期城市规划空间布局模式是外在动力,而市场条件下公共服务设施供需关系和供给方式则是根本动力。

Subject to the ability to pay and act,the quality of urban services that low-income population can enjoy is closely related to the level of public service facilities provided by the community life circle in which they live.Based on the urban redevelopment data and affordable housing data,this paper identifies the life circles of low-income communities in Wuhan,and uses POI to further evaluate the level of their public service facilities.The results show that the level of public service facilities in the life circles of lowincome communities is highly correlated with the urban spatial structure.In terms of spatial distribution,there is a trend of"weakening along the circle,spreading along the axis",Based on this,the life circle for low-income communities is divided into six categories.In terms of spatial differentiation mechanism,the public service levels of low-incomecommunity life circles aremainly affected by the supply capacity.The transition of the living space unit is the foundation.The urban planning layout pattern in different periods is the external driving force,and the supply-demand relationship and supply mode of public service facilities underthemarketconditions arethefundamental drivingforce.
