基于社会—空间视角的长沙市居住空间分异研究

The Study of Residential Differentiation in Changsha Based on the Social-Spatial Perspective

随着住房商品化政策的实施,城市居住空间在房价的"过滤"和社会经济差异的"分选"机制作用之下,不同职业背景、收入状况、价值取向的居民在住房选择上趋向于同类相聚,形成一种居住分化甚至相互隔离的状况。从社会—空间视角出发,利用住房数据与问卷调查相结合的方式,对长沙市的居住分异情况进行研究。通过聚类分析将长沙住宅划分成五类,归纳总结其分布和居民特性。以街道为单位从宏观和中观尺度,对各住宅阶层的分异指数进行定量研究,从而得到长沙居住空间分异的特征。最后,通过构建多元排序logistic住宅阶层选择模型,对分异的微观动因——居民的社会属性进行分析。
