摘　　要： 应用城市地理信息系统(UGIS)中有关城市缓冲区分析理论,引入GIS技术方法,从宏观角度突破行政区划界线把珠江三角洲城市群作为一个整体,从促进经济增长的意义上对其内部的核轴地带(即发展轴和拓展面)做了实体线状和面状30km缓冲空间分析,达到了一定距离邻域空间可视化效果。结果显示:①以广州市为拓展面的缓冲空间涉及了东莞市、佛山市和中山市的主城区以及深圳市和珠海市的部分城区。②以广深铁路为发展轴的缓冲空间涉及到了整个东莞市、深圳市行政区范围,以广珠高速公路为发展轴的缓冲空间涉及到了佛山市区,整个中山市和澳门特别行政区,珠海市的部分行政区,波及到了江门市和东莞市小部分行政区。本文根据珠江三角洲城市群核轴地带一定距离缓冲空间内所能辐射和影响到的其他城市的地域范围,并从地缘经济学的角度说明珠江三角洲作为未来经济集聚地,只有通过实现空间上的优势组合及协调发展才能够实现区域经济空间分布的不均衡到区域经济空间分布相对均衡的转变,最后提出了技术应用、缓冲距离选择等方面存在的问题以及进一步研究的方向。 This paper takes the macroscopic angle by breaking the Pearl River Delta Urban Agglomeration as a whole from administrative boundary, based on related theories on urban ubuffer area analysis of UGIS and GIS, as well as analysis on 30 km ubuffer areas of the entity line form and surface form on its inner core and axes zone （development axis and expanded surface） from promoting economic growth aspect, reaching the adjacent spatial visual effect between certain distance. The results show that （1） the ubuffer area scope of the expanding surface based on Guangzhou city includes the main city area of Dongguan, Foshan, Zhongshan and part of city area of Shenzhen and Zhuhai. （2） The ubuffer area scope of the development axis based on Guangzhou-Shenzhen railway includes nearly the whole administrative sphere of Dongguan and Shenzhen; the ubuffer area scope of development axis based on Guangzhou-Zhuhai highway includes the city area of Foshan, the whole Zhongshan city and Macao Special Administrative Region, part of Zhuhai administrative area, spreading to minor part of administrative area of Jiangmen and Dongguan. According to the regional scope which is eradiated and influenced by the ubuffer spatial sphere of the Pearl River Delta urban agglomerations core and axes region, this paper indicates from the viewpoint of geo-economics that as the future economic agglomerations, only by achieving the spatial combination of advantages and harmonious development can the Pearl River Delta achieve the conversion from unbalanced to relative balanced of regional economy in spatial distribution. Finally, the issues such as use of technology, choice of ubuffer distance and the further investigative direction are brought forward.
