中文摘要：

以第三次人口普查为基础数据,以街道（公社）为基本研究单元,采用因子分析和聚类分析的方法,对改革开放初期合肥城市社会空间结构进行了实证研究.结果表明：（1）1982年合肥市社会区划分为6大类,即工人集中分布区、机关干部居住区、知识分子集中分布区、农业人口散居区、铁路水运工人分布区、城乡人口居住交错区;（2）高度同质的机关干部居住区集中分布在老城区,居于城市几何中心;工人集中分布区、知识分子集中分布区、铁路水运工人分布区集中在环城路和一环路之间,呈扇形分布;农业人口散居区、城乡人口居住交错区分布在一环路以外;（3）改革开放初期,合肥城市社会空间结构呈现出以老城区为核心的＂单核＋扇形＂模式.

英文摘要：

The paper discusses the urban socio-spatial structure of Hefei during the initial stage of reform and opening-up,and the methods of factor analysis and cluster analysis are used to analyze the social spatial structure of Hefei area based on the data of the third census in 1982.The conclusions can be summarized as follows：1）The social areas of Hefei were divided into six categories：population of workers,government officials,population of intellectuals,agricultural population,railways and shipping transportations workers,and population of urban and rural interlaced zone.2）The government officials social area was located in the center of the old city,and the social areas of government officials population of workers,population of intellectuals,railways and shipping transportations workers were characterized by a fan-shaped distribution between the inner-ring road and the first ring road.The agricultural population area,population of urban and rural interlaced zone were distributed outside the first ring road.3）The urban socio-spatial structure model of Hefei appeared the synthesis of sector and single-nuclei pattern around the old city as the core during the initial stage of reform and opening-up.
