摘　　要：以城市中心职能强度指数分析为基础,应用和改进潜力模型对广东省各地级市的可达性进行综合测算和空间差异分析。结果表明,广东城市可达性及由此反映出来的经济联系的空间格局呈现同心圈层结构,并以佛山市禅城区和顺德区为中心向外辐射。广东珠三角城市群表现出最优的可达性和经济联系强度,而北部和东、西两翼城市在交通网络结构缺乏横向关联、远离经济中心的地理位置和过于依赖珠三角城市群的带动作用等因素的综合影响下,可达性程度和经济联系最差。通过城市可达性和经济联系强度的空间分异规律分析,揭示出广东区域空间结构和交通网络结构存在的问题,诠释城市经济水平、发展模式和地理区位对可达性空间分异的作用,从而为广东省城镇网络体系发育、区域经济协调及珠三角产业转移规划优化提供科学支撑。Base on the analysis of urban function intensity indicators,this paper uses and improves a potential model to implement the urban accessibility composite measure and spatial differences analysis in Guangdong Province.The results showed that the spatial patterns of urban accessibility and economic connection intensity in Guangdong Province present a spatial distribution of concentric spheres structure,and are radiated outward from the center of Chancheng and Shunde districts in the city of Foshan.The cities in the Pearl River Delta have the best accessibility and economic ties intensity.However,the cities in the north and east and west wings have the worst accessibility and economic connection intensity,due to the lack of horizontal associations of urban agglomeration,geographic location faraway the economic center and strongly dependence on the leading role of the Pearl River Delta.This paper analyzed the rules of spatial distribution differences of the accessibility and economic connections in Guangdong Province.This aims to reveal the problems in the existing regional spatial structure and transport network structure in Guangdong Province.And thus,the roles of urban economic development levels and scales and locations in spatial differences are interpreted.This should provide scientific support for urban network system growth,regional economic coordination and the industrial transfer planning and optimization in the Pearl River Delta.
