Abstract:
Size distribution characteristics of intercity bus hubs in China from 1997 to 2004 were analyzed regarding highway passenger volume as a size index of intercity bus hubs.Yearly fractal dimensions of intercity bus hub sizes were exactly calculated by a novel model.Fractal dimensions of the 200 biggest intercity bus hubs from 2000 to 2004 were 1.486 2 to 1.511 8, and that is consistent with fractal dimensions of Chinese urban system sizes.It showed that the size distribution of intercity bus hubs had fractal structure.Fractal dimensions from 1997 to 2004 indicated that intercity bus hub size distribution grew from bi-fractal to single fractal.It is concluded that the intercity bus hub system is in evolutionary progress, and the Central Government should support large intercity bus hubs more to optimize system structure.
以公路客运量为规模参数分析了1997年至2004年中国前200位主要公路客运枢纽规模分布的分形特征, 采用精确计算方法得到历年公路客运枢纽规模分布的分维数.发现中国公路客运枢纽体系的规模分布符合从双分形到单分形发展的结构特征, 2000年至2004年规模分布维数介于1.486 2~1.511 8之间.这与城镇体系规模分布维数一致, 说明现阶段中国公路客运枢纽体系与城镇体系规模分布结构相适应.结果表明, 公路客运枢纽体系处于较好发展阶段, 政府需加强大型公路客运枢纽建设推动其结构优化.
