2025年黄河调水调沙圆满结束 实现腾库迎汛水库排沙生态补水等多赢目标

Core Viewpoint - The Ministry of Water Resources has successfully implemented the 2025 Yellow River water and sediment regulation project, achieving multiple objectives including reservoir sediment discharge, ecological improvement, and drought resistance support [1][3]. Group 1: Project Implementation - The water and sediment regulation project lasted 18 days, with the Xiaolangdi Reservoir achieving a maximum discharge flow of 4,820 cubic meters per second and a maximum sediment concentration of 250 kilograms per cubic meter [1][2]. - The project involved coordinated operations among multiple reservoirs, including Xiaolangdi, Sanmenxia, and Wanjiazai, to optimize water management and sediment control [2][3]. Group 2: Achievements - A total of 3.36 billion cubic meters of reservoir capacity was released to ensure safety during the flood season [3]. - The Sanmenxia Reservoir achieved a net sediment discharge of 5.3 million tons, while the Xiaolangdi Reservoir discharged 16 million tons, effectively reducing sediment accumulation [3]. - The main river channel's flow capacity improved significantly, with the minimum flow capacity increasing from 1,800 cubic meters per second in 2002 to approximately 5,000 cubic meters per second currently [3]. - Ecological benefits included 1.5 million cubic meters of ecological water supply to the Yellow River Delta wetlands, enhancing biodiversity [3]. - During the project, 690 million cubic meters of water were diverted to support drought relief efforts in downstream provinces [3]. Group 3: Future Actions - The Ministry of Water Resources will continue to monitor rainfall and water conditions closely, ensuring effective flood prevention measures are in place as the country enters the critical flood season [4].
