中文摘要：

本文基于对2007-2014年成都市保障性住房的建设规模与空间分布的实地调研,运用Arc GIS绘制成都保障性住房的空间分布图,进一步将保障性住房与公共服务设施的空间分布差异以分布图的形式展现,并从物理空间可达性角度,分析研究成都保障性住房集聚区与公共服务空间匹配问题。通过Arc GIS最短距离结果研究发现,成都保障性住房对公共服务设施的可达性优良排序为绿地〉地铁〉重点中学〉商业中心〉优等综合性医院。从公平的价值目标来看,保障性住房与公共服务设施的空间布局的差异性,导致了一定的公共服务获取的不平等,而公共服务的不平等获取,将在保障性住房空间集聚的基础上得到强化。从公共服务设施分类来看,成都保障性住房集聚区基本公共服务均等化而优质公共服务差异化特点非常明显。公共服务设施的布局在一定程度上被资本化入商品住房价格的现实背景下,政府在公共产品提供中坚持＂注重效率与维护社会公平相协调＂是非常重要的原则,也是保障性住房＂宜居＂与否的重要标准。

英文摘要：

Based on the first-hand information that the author collected through field investigation and data collection, the spatial distribution map of Chengdu affordable housing is depicted using ArcGIS. The affordable housing policy on the floating population, the construction scale and spatial distribution of affordable housing in Chengdu are described in detail. Based on ArcGIS, the map of the spatial distribution of both affordable housing and public facilities are exhibited. From the perspective of efficiency and equity, the case analyses the issues about the accessibility between the affordable housing and the public facilities. According to the classification of public service facilities described in the case, it is found that characteristics of equalization of the basic public services and differentiation of high-quality public service in Chengdu affordable housing cluster are very obvious. The government should insist on the principle of ＂focusing on the coordination between efficiency and social equity＂ in the provision of public goods. And it is also an important criterion to evaluate ＂livability＂ of Chengdu.
