The intelligent waterway is an inevitable trend for the development of inland waterway informatization.Facing the business demand of the Yangtze River waterway including the smooth,efficient,safe and green development of the inland water transportation,we propose the system of key technology of the Yangtze River intelligence waterway including three levels and 20 key technologies,construct a support diagram between the system of key technology and the goals of inland river water transportation development,and point out the research and development tasks for the future.All these will provide a theoretical guidance to the synchronous breakthrough for the key technologies of the Yangtze River intelligence waterway.
