Core Insights - The Yellow River basin officially entered the flood season on July 1, 2023, with the water and sediment regulation task for 2025 initiated on June 23, lasting 17 days [1] - The Yellow River Delta is a crucial wetland ecosystem in China, recognized as an "international airport for birds," and has received over 900 million cubic meters of ecological water replenishment since 2008 [1] Group 1: Water and Sediment Regulation - Water and sediment regulation is a governance method that involves scientifically managing reservoirs to reduce riverbed siltation and improve river morphology [3] - This process includes controlling the discharge flow from upstream reservoirs to create artificial flood peaks, which transport sediment downstream to the sea, ensuring long-term river stability and ecological health [3] - Since 2002, the national government has implemented water and sediment regulation for the Yellow River based on extensive scientific research, addressing drought resistance and flood preparation [3] Group 2: Ecological Impact - During the water and sediment regulation period, ecological replenishment is initiated, revitalizing the ecological functions of the Yellow River Delta [5] - The wetland area receiving ecological water replenishment has reached 360,000 acres, with bird species increasing from 187 in 1992 to 374 in 2024 [5] - The stable plant community of reeds has developed in the replenished wetlands, leading to increased density and abundance of benthic organisms [5]
