Abstract: Air transport is an important component of national integrated transport systems. However, its network properties differ a lot from the integrated transport networks. Different from random networks of other transport modes, air transport network is hub-and-spoke structure with typical scale-free network characteristics. The transport quantity highly concentrated at hubs and main routes. Airport nodes are the important infrastructures in networks and potential efficiency bottlenecks. On the integrated transport channels, air and other transport modes play different roles in the nonoverlapping area of transport market and compete in the overlapping area. At the integrated transport hubs, they are linked up and collaborated. The airports as transport hubs are the key points in efficiency performance of integrated transport. They need other transport modes’ active linkup and collaboration to make the best use of advantages in high efficiency and high speed. Based on the property differences, the air transport hubs are necessarily to be optimized in linking up with other modes in the integrated transport systems to achieve satisfactory collaboration between the two kinds of transport networks.

摘要： 航空运输是国家综合运输系统的重要组成部分，但航空运输网络与综合运输网络在网络特性上区别明显. 与综合运输网络呈现随机网络的特征不同，航空运输网络具有无标度网络的特征,枢纽节点和干线航段的集中度高，网络呈现为轮辐式结构，机场节点是网络中的重要基础设施，也易成为网络效率的瓶颈. 在综合运输大通道上，航空运输方式与其他交通方式的关系表现为在客货运输市场上的自然分工和自由竞争；在综合交通枢纽上则表现为衔接与合作关系. 机场枢纽是体现综合运输效率的关键点，需要其他运输方式的主动衔接与配合，以发挥航空运输高效快速的优势. 基于不同的网络特性，为实现两种运输网络的协同，有必要优化和改善航空运输与综合运输网络的衔接.
