（何以中国·黄河安澜）“定海神针”守护黄河安澜

Core Viewpoint - The Xiaolangdi Water Conservancy Project serves as a critical control project for the governance, development, and protection of the Yellow River, significantly impacting its flow and sediment management [1][3]. Group 1: Project Significance - The Xiaolangdi Water Conservancy Project controls 92.3% of the Yellow River's watershed area, 91.2% of its runoff, and nearly 100% of its sediment transport, highlighting its pivotal role in the river's management [1]. - The Yellow River, known for its high sediment content, has an annual sediment transport volume of 1.6 billion tons, necessitating effective management strategies to address sediment accumulation [1]. Group 2: Operational Achievements - Since 2002, the Xiaolangdi Water Conservancy Project has completed 30 sediment and water regulation operations, increasing the downstream riverbed's flow capacity from less than 1,800 cubic meters per second to 5,000 cubic meters per second [3]. - The average riverbed incision in the main channel downstream has reached 3.1 meters, ensuring flood safety and promoting a harmonious interaction between environmental and water conservancy engineering [3]. Group 3: Technological Advancements - The project has accelerated its digital transformation, establishing a digital twin platform in 2023, which integrates water, sediment, and electricity management for unified control [3][4]. - The use of advanced monitoring technologies, including radar, drones, and intelligent monitoring systems, enhances real-time oversight and intelligent scheduling of reservoir operations [4]. Group 4: Future Outlook - With ongoing technological advancements, the Xiaolangdi Water Conservancy Project is expected to continue its role as a "stabilizing force" for the long-term safety of the Yellow River and the sustainable development of the surrounding economy and society [4].
