摘要
以珠江三角洲城市群①为研究对象,在改进"大都市均匀度指数"的基础上建立了空间集聚与扩散的量化指标,定量化测度了近10多年来该地区空间集聚的程度与动态趋向,进而分析了该地区空间集聚与扩散的表象与特征。其结果表明:珠江三角洲城市群目前正处于以集聚为主导的阶段,空间集聚表现出明显的轴线性、空间指向性(中心指向、道路指向、海洋指向)以及非完全集聚的特征。且珠三角城市群在以集聚为主导的空间发展过程中,区域发展趋向于均质化。具体表象为以中小城市增长为主的城市规模分布动态趋向以及大中城市的郊区化倾向。
Taking the Urban Agglomerations of Pearl River Delta as the object of study, this paper tries to build up the quantitative index of Spatial Agglomemtion and Dispersion basing on the moderation of the Uniformity Index of Metropolitan. This study quantizes the degree and the dynamical trends of spatial agglomeration and analyzes the signs and characters of the spatial agglomeration and dispersion in the area. The study shows that the Urban Agglomerations Of Pearl River Delta is in its period in which the spatial agglomeration is prevailing. The agglomeration bears the characters such as in - line agglomeration, spatial index and incomplete agglomeration. And the area turns to show the dispersion which is marked by the trends of the changes on the population size hierarchy showing the prevailing of media and small towns and the suburbanization of the metrooolitan,during the agglomeration period.
