Merits and demerits should be weighed from many aspects when a large airport traffic hub is built since the hub, as an important infrastructure, involves multiple traffic modes. Integrating rail transit services into the hub constitutes a key to enhancing the quality and efficiency of the hub itself. Typical cases of large airport traffic hubs in different countries were analyzed in terms of their experience in planning, construction and management as well as the key technologies of rail transit planning. A general idea for connection planning and key points for the design to embrace high-speed rails, intercity rails, urban rails, etc, are presented for the innovative development of integrated traffic hubs.%论述大型空港枢纽作为重大乃至特大的多模式交通综合体的重要性,指出在构建过程中需要进行多方面的权衡和考虑.结合轨道交通的发展及其对城市的重要性,说明做好与轨道交通的衔接已成为大型空港枢纽发挥功效和拓展功能的关键.在总结国内外大型空港枢纽规划、建设、管理经验的基础上,剖析相关城市和地区的典型案例,分析空港枢纽构建过程中轨道交通规划设计的关键技术,提出衔接规划的总体思路以及面向高速铁路、城际轨道与城市轨道交通的设计要点,促进枢纽一体化开发的创新与实践.
