　　Abstract：The hydro-meteorological information service system of Yangtze River Basin covers the whole process of hydro-meteorological information collection, forecasting production, data management and results release. Through the introduction of the design idea, overall framework, system functions, its application in flood control and disaster relief, water engineering scheduling, river water quality protection, water resources management and protection is illustrated. By integrating the reservoirs information sharing platform, hydrological App and forecast & dispatching system in the Yangtze River Basin, the information service system is expanded, in order to share all links of data flow and construct a process system from service products production to products release. By using the information management platform, unified management of data collection, processing, analysis and sharing is realized, and the timelines and relevance of the services are improved. The system has been fully applied in the Yangtze River Basin Flood Control in 2020, and can provide comprehensive, professional and customized hydro-meteorological information services with regard to flood and drought disaster forecasting, water transfer scheduling and water resources management for water-related departments along the Yangtze River Basin.
