都市圈空间界定方法研究——以南京都市圈为例

Research For Defining the Scope of the Metropolitan Are-a: A case study of Nanjing Metropolitan area

全球城市时代的来临,城市发展出现一个新的空间单元——都市圈。作为都市圈研究重要组成部分的都市圈空间界定方法理 应引起人们的关注。本文首先回顾了国内外都市圈空间界定方法研究的主要成果,概括出影响都市圈空间界定的主导要素为 空间、时间、流量和引力,以此为基础探索了一条新型的、综合型的都市圈空间界定方法:即分别以四个要素为依据界定都市圈 范围,然后对四个范围进行空间上的叠加,取其交集、并集和补集,它们分别对应都市圈的直接影响圈、泛影响圈和间接影响圈。 最后以南京都市圈为例对新方法进行了初步论证。

This paper explored a way to define the scope of the metropolitan area. Firstly, this paper synthesizes that four factors which included space, time, flow and gravity mainly influenced the scope of the metropolitan area. Secondly, based on the four factors separately four kinds of different scope could be got. Thirdly, overlapped the four kinds of scope and divided the whole scope to directly influenced area, generally influenced area and indirectly influenced area. At last the new kind of way is applied to Nanjing metropolitan area.
