以第3次和第5次人口普查数据为基础数据,采用因子分析和聚类分析的方法,研究了1982~2000年近20 a间合肥城市社会空间结构演变特征。结果表明,近20 a合肥城市社会空间结构的影响因子、社会区类型、模式及其形成机制均发生了显著变化。1982年合肥城市社会空间结构简单,主要分布在一环以内,其中环城路(城墙遗址)内老城区的社会区高度同质,环城路与一环路之间的社会区呈扇形分布,形成以老城区为核心的“单核+扇形”模式;2000年城市社会区分异趋于复杂,社会空间重构显著。老城区的社会区分异显著,多个新的“飞地型”社会区出现,形成以老城区为中心的“圈层+扇形+飞地型”模式。最后从合肥省会效应、城市规划与旧城改造、工业化与市场驱动力、户籍制度改革等方面探讨了形成机制。
Based on the data of the 3rd and 5th censuses, the evolution of social spatial structure in Hefei was studied by means of factor analysis and cluster analysis over the past 20 years from 1982 to 2000. The results show that the influential factors, social types, patterns and formation mechanisms of urban social spatial structure have all undergone significant changes in the recent 20 a. The urban social space in Hefei in 1982 was simple in structure and mainly distributed within a circle. The social areas in the Old City within Huancheng Road (city wall sites) were highly homogeneous and the social areas between Huancheng Road and First Ring Road were fanned out. Forming a “single-core + fan-shaped” model with the old city as the core. In 2000, the differentiation of urban society tends to be complicated and the reconstruction of social space is remarkable. The social division of the old city is distinctly different. A number of new “enclave-type” social areas have emerged, forming a “circle + fan + enclave” model that takes the old city as the center. Finally, the forming mechanism was discussed from the provincial capital effect in Hefei, urban planning and urban renewal, industrialization and market driving force, and the reform of household registration system.
