成都市社会空间结构演变研究(2000～2010)

Socio-spatial Structure of Chengdu and Its Evolution(2000～2010)

以第5次和第6次人口普查数据为基础,运用因子和聚类分析等方法研究了中心城市成都2000～2010年间的社会空间结构演变趋势。研究发现:10年间成都城市社会空间结构的主因子、社会区、结构模式均发生了显著变化。主因子演变特征归纳为一般工薪阶层及专业技术人员因子和产业工人因子呈现较大变化;而外来人口和居住条件因子、高学历人口和少数民族人口因子呈现一定的稳定性和持续性。社会区演变特点归纳为中心老城区空间结构优化与功能定位升级,并向"三降两提"演变;知识分子居住区扩展并与少数民族聚集区分离,呈现出居住分异趋势;外来人口逐渐向二三产业流动且集聚区规模扩大;农业人口聚集区逐渐远郊化及蓝领人口区域的凸显。社会空间结构模式由2000年的单一化和同质化的"圈层+扇形"结构,向2010年的"圈层+扇形+多核心+多组团"格局演变,各类型空间区域扩大,空间异质化更为明晰。

Based on the data of the 5 th and 6 th censuses,factor and cluster analysis and other methods were used to study the evolution trend of social spatial structure in the central city of Chengdu from 2000 to 2010.It is found that the main factors,social areas and structural patterns of urban social spatial structure in Chengdu have changed significantly in the past 10 years.The evolution characteristics of the main factors can be summarized as follows:the factors of general wage earners,professional and technical personnel and industrial workers show great changes;while the factors of immigrants and living conditions,highly educated population and minority population show certain stability and sustainability.The evolution characteristics of social areas can be summarized as the optimization of spatial structure and upgrading of function orientation in the old urban areas,and the evolution towards'three descent and two mention';the expansion of intellectuals’residential areas and the separation from minority agglomeration areas,showing a trend of residential differentiation;the gradual migration of foreign population to secondary and tertiary industries and the expansion of agglomeration areas;and the agglomeration districts of agricultural population gradually become suburbanized and the prominence of blue-collar population areas.The pattern of social spatial structure has evolved from the single and homogeneous'circle+fan'structure in 2000 to the'circle+fan+multi-core+multi-group'pattern in 2010.Various types of spatial regions have expanded and the spatial heterogeneity has become clearer.
