为水利治理装上了智慧“大脑” 我国数字孪生水利体系框架基本形成

Group 1 - The digital twin water conservancy system framework in China has been established, achieving significant results in flood and drought disaster prevention, water resource management, and allocation, providing strong technical support for high-quality water conservancy development and national water security [1] - The digital twin water conservancy system consists of digital twin basins, digital twin water networks, and digital twin water conservancy projects, integrating big data, cloud computing, and artificial intelligence with water conservancy operations [1] - The Ministry of Water Resources has implemented a series of documents from multiple levels to systematically promote the construction of the digital twin water conservancy system, with 94 pilot tasks completed and 11 key projects, including the Three Gorges and South-to-North Water Diversion projects, already in practical application [1] Group 2 - The water conservancy department is accelerating the construction of an integrated monitoring and sensing system, covering 34 remote sensing satellites, over 180 rain radar stations, 136,000 ground hydrological stations, and more than 300,000 engineering safety monitoring points [2] - The digital twin technology is primarily applied in flood and drought disaster prevention, with a comprehensive monitoring network enabling real-time monitoring and rolling forecasts, extending flood prediction periods from 3 days to 10 days with a 90% accuracy rate [2] - A multi-level flood risk warning system has been established, resulting in the issuance of 12,400 flood warnings and 1.21 million mountain flood disaster warnings, successfully organizing the evacuation of 15.55 million people [2] Group 3 - The construction of the digital twin water conservancy system enhances the efficiency of water governance, directly benefiting the public by addressing issues of illegal occupation, extraction, and construction in river and lake areas [3] - Modern monitoring technologies such as high-resolution remote sensing satellites and drones support the regulation and normalization of river and lake management, leading to significant improvements in the appearance of water bodies and increasing public satisfaction and safety [3]
