广州市社会空间的因子生态再分析

AN ECOLOGICAL REANALYSIS ON THE FACTORS RELATED TO SOCIAL SPATIAL STRUCTURE IN GUANGZHOU CITY

运用因子分析、聚类分析方法对广州市中心区１９９０年人口普查数据进行了研究。从９类４７个变量中抽取出５个形成广州市社会区类型的主因子，根据各主因子的得分，把广州市中心区划分为七类社会区，并把形成广州市社会空间分异现象的原因归结为五类。通过与１９８５年类似研究结果的比较，发现广州市社会空间结构的分异现象更趋明显，具体反映在人口“外溢”、居住条件改善及新开发区的形成等方面。最后就如何引导广州市社会空间结构演变进行了讨论。

This paper studied the soctal spatial structure of Guangzhou city by factorial ecologicalanalvsis and cluster analysis(WARD method).Based on the data of 1990 national census,theresult obtained from a principal component analysis of 47 variables across 91 subdistricts inGuangzhou city shows the most important five principal components. Those account for morethan 70% percent of total variance.Accourding to the factor scores,the Guangzhou City can be divided into seven types ob-tained from a cluster analysis(WARD method).The mechanism forming the spatial patterns of social areas mainly includes five factors.Before this paper,a resemble studing had been undertaken by Xu Xueqiang et al in 1985.Bycontrasting the two results,it was found that the degree of social spatial differentiation inGuangzhou becomes more remarkable. The changes mainly show the moving of population tothe suburbs,the improving of housing conditions and the creation of newly development area.
