摘要
利用城际客运交通流,从城市和功能区两个尺度对珠三角城市之间功能联系的空间格局进行分析,结果表明:联系强度上呈现出中心与外围、东岸与西岸、三大次区域不均衡的空间分异特征,联系方向上呈现出总体指向广州和深圳、局部非连续化的空间组织特征,联系节点上呈现出梯度层级和多中心功能布局并存的空间结构特征。当前珠三角正处于经济结构转型升级、区域一体化政策趋势加强、区域交通基础设施快速兴建的阶段,这些因素会对区域内资源要素流的性质类型、空间配置和流动廊道产生深刻影响。
Based on the data ofintercity passenger traffic flow, this paper analyses the spatial pattern of Pearl River Delta＇ s city function connection in two scales of city and functional region. It is found that the connection intensity shows imbalanced spatial variation in center area and peripheral area, east coast and west coast, and three subregions; the connection direction demonstrates overall spatial pattern of orienting to Guangzhou and Shenzhen, as well as partial discontinuity; the connection nodes suggest spatial structure of gradient hierarchy and polycentric distribution. Besides, nowadays PRD is in the phase of economic structure transformation and upgrading, facilitating the implementation of regional integration policy, and rapid construction of regional transport infrastructure, which exert great impacts on the property, distribution and corridors of resource flow in the region.
