摘 要: (中)摘要 城市副中心建设能够有效平衡超大城市的集聚效应和扩散效应,缓解城市的人口压力,疏散其功能,促进城市向真正的多中心发展。本文以北京为例,从城市副中心的内涵入手,深入分析了不同形态城市副中心的含义与特征以及城市副中心建设的必要性。认为北京副中心城市应是以现有基础为重要依托、以轨道交通和大运量交通为纽带、以明确的生态区域为界限的、功能完整、组团式布局的新城市。通过建立单纯考虑区域发展和主要考虑为北京“分忧”的两套指标体系,对哪座新城适宜作为北京城市副中心建设的起步区进行了定量研究,由此说明不同功能的城市副中心应基于其功能要素设计指标体系以进行选址。在此基础上提出了北京城市副中心的发展思路和政策建议。

Abstract: (英)摘要 SubCBD can effectively balance the agglomeration effect and diffusion effect of the large cityIt can also effectively alleviate the population pressure and scatter the function of central district, which contribute to becoming the real multicentersTaking Beijing as an example, we firstly present a deep analysis of the connotation and characteristics of SubCBD with different forms, and study the necessity of constructing SubCBDWe put forward that the SubCBD of Beijing should be a new grouptype layout city with complete function, which is based on the existing foundation, linking up with rail transit and large volume transportation and bounded by the clear ecological regionThen a quantitative analysis has been carried out for which new city should be the starting area for the SubCBD of Beijing, through establishing two sets of index system:pure consideration of regional development and the main consideration for sharing the burden of BeijingTherefore, SubCBD should be located according to different index systems considering its factionOn this basis, we propose the development thought and policy recommendations for Beijing SubCBD.

对都市圈副中心级城市发展的研究始自对“城市病”的关注。以北京为例,北京“城市病”的主要成因,不是全行政区的人满为患,而是中心城区的人挤为患。导致人挤为患的主要原因在于北京“同心圆”式的城市发展模式,使商业、文化、教育、医疗等功能过度集聚在中心城区内。要缓解北京“城市病”,关键在于大力疏解中心城区的功能、避免过度集聚[1]。近十年来,为改变单中心的城市发展方式,北京市不断研究新的空间功能布局方案,既有规划中的新城建设即可窥见一斑。……
