摘要
运用社会网络测度方法,以珠三角城市区域各城市每日长途客运进出班次作为客运交通流的替代性动态数据,完成对珠三角多中心城市区域功能多中心性的定量测度与比较分析。研究发现,珠三角城市区域客运交通流呈现空间上的规模效应、尺度效应、距离效应、方向效应和结构效应;基于客运交通流功能联系测度的珠三角城市区域功能多中心性可以发现,珠三角功能多中心性发育程度较高,且具有尺度敏感、地区的差异性,呈现变化的方向性。
The study on the characteristics of fimctional polycentricity of urban regions based on fimctional contacts is the inevitable requirement from the global integration and informationization development. Carrying on researches on the functional polycentrieity of PRD urban region is crucial in theory and practice. By using social network method, this paper taking the inflow and outflow of each bus station as the passenger traffic flow to analyze the characteristics of the network of passenger traffic flow, measures the level of functional polycentricity of PRD. The results indicate that the network of passenger traffic flow of PRD contains certain characteristics, such as the scale effect in quantity, the scale effect in geographical space, the distance effect, the orientation and structure effect. Based on the quantitative measurement, the research shows that the level of fimctional polycentricity of PRD is relative high, which shows significant centrifugal effect. The research also finds that the functional polycentricity of PRD is scale sensitive, presents the change in certain direction, contains regional difference, and gets the same variation tendency in different functional network.
