三峡工程蓄水运用20年综合效益发挥与展望
Review and Prospect of Comprehensive Benefits of Three Gorges Project in 20 Years of Operation
摘要
Abstract
The Three Gorges Project has operated for 20 years since 2003,achieving all major design objectives while continuously optimizing operational strategies to suit changing conditions and developmental needs.Its multi-faceted benefits in flood control,power generation,navigation,and water resource utilization have been fully real-ized.By the end of 2023,the project has executed 66 flood detention operations,retaining an accumulated flood of over 208.8 billion m3,ensuring flood safety for Jingjiang River and substantially easing pressure on flood protection in the middle and lower reaches of Yangtze River.Power generation has surpassed 1 660 billion kW·h,equivalent to saving 510 million tons of standard coal and reducing carbon dioxide emissions by 1.33 billion tons.Channel con-ditions have markedly improved,facilitating a freight volume exceeding 2 billion tons,thus catalyzing the rapid de-velopment of Yangtze River navigation.During dry seasons,approximately 340 billion m3 of water was replenished downstream,effectively securing water supply safety.Ecological operations have yielded significant results,notably in the restoration of four major Chinese carps.To address challenges posed by frequent extreme hydrological events and ensure the long-term safe operation of the Three Gorges Project,as well as maximize its comprehensive bene-fits,future prospects entail advancing meteorological and hydrological forecasting technologies,optimizing the reser-voir's operational schemes,leveraging and applying innovative achievements,and implementing intelligent man-agement practices.关键词
