多中心城市区域空间结构的研究和判断是制定适宜区域空间政策、推动其健康发展的前提和基础。珠三角地区作为我国快速发展的经济核心区和城镇密集区，其空间结构正在发生着显著的变化。以珠三角县级行政单位为基本空间单元，采用主成分分析和聚类分析法，对珠三角地区2000，2005，2010年多中心空间结构特征及演变进行研究。珠三角地区经历了从“核心—边缘”特征明显的单中心模式到“多中心”结构特征显著的发展历程，其演变模式总体上符合弗里德曼的区域空间结构演化理论。但在城市区域的空间尺度，钱皮恩的“离心模式、组合模式和融合模式”对其空间结构演变具有更好的解释力。现阶段，珠三角地区基本实现了经济中心和人口中心的空间耦合，但各中心在职能上仍然有所差别。

The study of polycentric-spatial structure is not only the premise of making appropriate policies for special development , but also the basis of sound development of the polycentric urban region .Pearl River Delta ( PRD) region is one of the rapid development cores of China , which spatial structure is changing .Taking PRD coun-ty-level administrative units as spatial bases , adopting principal component analysis and cluster analysis , this paper focuses on the characteristics and changes of spatial structure of the polycentric urban region in PRD around 2000, 2005 and 2010, and discusses its evolution mechanism .PRD region experiences significant changes from the core -pe-riphery-based single-center mode to polycentric-based mode , its evolution model is generally consistent with the re-gional spatial structure of J .R.Friedman evolution theory .But in the city regional spatial scale , the centrifugal mode , combination mode and integration mode of A .G.Champion has better explanatory power .PRD region has basically re-alized space coupling of economic center and population center , but the functionally of each center is still difference .
