基于因子分析的北京城市功能空间布局研究

论文以北京市为例,采用因子分析法,对北京市内18区县反映城市发展状况指标进行定量综合评估,以明确北京市各区县城市发展的主导因素,为确定各区县发展优势及功能定位提供科学依据.并结合北京市现有城市功能空间分布特点,提出在城市服务核心区(主城区)和生态涵养区(山区)之间的城市功能拓展区内,建立朝阳-通州、丰台、石景山、海淀4个发展区.通过在各发展区内形成人流、物流循环,分担主城区人口、功能过于集中的压力.并通过功能区之间的产业连接,形成环状产业发展轴,构成北京国际化大都市发展骨架.

A research on Beijing' s urban functions distribution based on the methods of factor analysis

This paper gives an integrated quantitative evaluation on Beijing development status by applying the methods of factor analysis to indicators of 18 districts (counties) in Beijing. It tries to explore the leading factor determining the development of each district (county) and provides a scientific basis for setting up each district 's (county's) advantages and functional orientation in Beijing region development. On the basis of Beijing's current urban spatial structure, a plan is put forwarded that in the zone providing extended urban functions, between kernel serving zone (the old city area) and ecological maintenance zone (mountain area), four development zones (Chaoyang_Tongzhou, Fengtai, Shijingshan, and haidian) should be established. By forming population and merchandize flow circle inside each development zone respectively, the pressure caused by over_centralized population and urban functions in the old city area can be significantly reduced. Moreover, development zones interlink with each other to produce a functional reciprocity and constitute an industrial ring, which is the framework of Beijing metropolitan area development.
