Abstract：Water supply safety of the Three Gorges Project shall be the core for water security in the middle and lower reaches of the Yangtze River Basin.Frequent drought events pose a severe challenge to the water supply safety.The core issues of water supply safety faced by the Three Gorges Project are discussed from five aspects of incoming water forecasting based on multi-source information such as satellite remote sensing,drought forecasting and early warning in the middle and lower reaches of the Yangtze River Basin,efficient utilization of flood resources,drought limited water level and drought resistant scheduling and ecological security.By summarizing relevant technological innovations,the urgency of ensuring water supply safety of the Three Gorges Project are emphasized.Key measures to enhance water supply safety are proposed that mainly include integration of multi-source information to improve the accuracy of incoming water forecasting,establishment of a sound monitoring,forecasting,and early warning mechanism for drought in the middle and lower reaches of the Yangtze River Basin,integrated research on flood season design and scheduling of reservoirs in the middle and upper reaches of the Yangtze River under the new situation,study of drought limited water level and drought resistant regulation mechanism of the Three Gorges Reservoir,and measures of integrating water quality protection,ecological regulation and control of water-level fluctuation zone to ensure ecological security.
