摘　　要：为探明运输枢纽的形成机理,用中心地理论解释运输站场体系结构,分析了运输站场发展动力,并提出了运输站场发展模型。认为在站场规模效应和客货流聚集效应作用下,运输站场发展先以集中化为主,随着站场边际收益下降而分散化趋势显现,站场达到规模极限则会分化为多个站场而形成运输枢纽。结合汕头市公路主枢纽发展过程分析,证实了运输站场结构演化经历站场极化、站场扩散及运输枢纽阶段,运输枢纽的形成是规模效应与客货流聚集效应作用的结果。For exploring the evolvement process and formation mechanism of transportation hub, this paper analyzed the configurations of transportation terminal system with Central Place Theory, presented a new model about transportation terminal development. It was pointed out that the station appeares under polarization force during earlier time, and the station is expanded by diffusion power as marginal return decreasing. When capacity of transportation station approaches it＇s limit, several new stations appear around it sharing the excessive volume, so the transportation hub is developed. As case study shows that transportation terminal has three forms in different stages. agglomeration level, diffusion level and hub level, the transportation hub is developed from transportation terminal by the effect of agglomeration and economics of scale. 5 figs, 11 refs.
