Abstract：The Yongding River Water Diversion Project is the main source of production and domestic water supply for Beijing.Its headwater,the Sanjiadian Water Conservancy Hub,is the first controlling water conservancy project connecting the Guanting Gorge section and the plain section of the Yongding River,playing a key role in providing water for urban development in Beijing and the construction of river and lake ecological environments.This paper analyzes the history of water resources dispatching and current development status of the Sanjiadian Water Conservancy Hub over more than 60 years,summarizes the achievements in water resources,water ecology,and water economy,and identifies existing problems.With the construction of the Hexi branch and West Storage Project,as well as the continuous updating of water management concepts in the new era,relevant measures and suggestions are proposed for the dispatching operation of the Sanjiadian Water Conservancy Hub under new conditions,which are of great significance for further improving regional water resources dispatching and management.
