摘　　要：交通流作为城市间要素流的重要表征,已逐渐替代传统研究中的城市属性数据,被用于城市网络分析研究中。基于成渝城市群51个城市单元间的铁路、公路客流,从联系强度和节点等级两个角度分析成渝城市群城市网络特征。研究表明:(1)成渝城市群城市网络呈现"双核、一轴、两带"布局,成渝、成绵乐、渝万客运专线以及沿江高速公路沿线成为高层级网络集中分布地带。(2)城市网络极化现象显著,成都市市区与重庆主城区辐射能力过强,高等级网络过于集中,次级城市网络发育不足。(3)公路运输仍是成渝城市群城市联系的基础运输方式,覆盖率高,而高铁动车对城市网络等级的提升作用明显,强于公路交通与普通列车。此外,行政要素依旧会对城市网络产生影响。Passengers flow is the most active factor of spatial interaction between urban networks,and it is being used in the research of urban network structure,gradually replacing the attribute data of cities used in traditional approach.Based on inter-urban railway and highway passengers flow data,this paper analyzes the characteristics of Chengdu-Chongqing urban agglomerations.The result shows:①The urban network in Chengdu-Chongqing urban agglomerations presents layout of“two cores,one axis and two belts”.Chengdu and Chongqing play the roles of two cores.The corridor between Chengdu and Chongqing is the axis.Chengdu-Mianyang-Leshan belt and Chongqing-Wanzhou belt along the Yangtze River become two concentrated regions of high density urban interactions.②The phenomenon of polarization is obvious in Chengdu-Chongqing urban agglomeration.Urban areas of Chengdu and Chongqing have stronger power of resources agglomeration.The highest level cities become so concentrated that the secondary urban networks cannot develop well.③Transportation by road still plays the most important role in Chengdu-Chongqing urban agglomeration,while transportation by high speed railway increases faster,and give a greater promotion to urban networks.The element of administration still has big influences on the urban systems.
