摘 要：随着通信导航技术在长江航道的发展和应用，已给越来越多的航运船舶提供了先进的信息沟通和导航服务。针对传统实体航标占用可航行水域、设标周期长和难以维护的短板，结合长江干线实际情况，充分发挥虚拟航标的特点，探索电子航道图虚拟航标和AIS虚拟航标的发布方式，并进行发布实验，以验证船舶通过连续桥区的安全性和提升了航道尺度利用率。两种虚拟航标的发布方式能有效的弥补各自的局限性，达到优势互补，为虚拟航标在长江干线航道的推广提供保障。

Abstract： With the development and application of communication and navigation technology in the Yangtze River channel， more and more shipping ships have provided advanced information communication and navigation services. In view of the facts， i.e.， the traditional physical navigation mark occupying the navigable waters， the long period of calibration and the difficulty inmaintenance， this study considers the actual situation of the Yangtze River trunk line and the characteristics of the virtual navigation mark， explores the release method of the virtual navigation mark and the AIS virtual navigation mark， and experiments to verify the safety of the ship through the continuous bridge area and improve the channel size utilization. The release methods of the two virtual navigation aids can effectively compensate for their respective limitations and complement each other， so as to provide guarantee for the promotion of virtual navigation marks on the Yangtze River.Keywords： aids to navigation; AIS; electronic channel map; release method
