信创赋能数字孪生水利防洪"四预"决策支持系统建设与实践OA

To address frequent floods and droughts,the inadequate intelligence of traditional flood regulation modes,and potential supply chain risks in water conservancy information systems in China,this study developed a digital twin water conservancy decision support system for flood control featuring"Four Pre"functions based on information technology application innovation.The system built a full-stack domestic-substitution technology foundation comprising domestic software,hardware,and satellite and radar monitoring networks.Core technologies,including refined"cloud-rain"short-term and impending precipitation forecasting,full-chain rainfall and water regime monitoring and forecasting,intelligent model construction and simulation,two-way deduction of reservoir-group dispatching and integrated"Four Pre"through integration,were developed to form a closed-loop business framework.The system effectively extended flood forecast lead time and improved prediction accuracy.The system has been applied during numerous major floods,droughts,and emergencies,the system reduced disaster losses.The findings can improve the ability of flood and drought disaster prevention,achieve technological autonomy and controllability in water conservancy infrastructure,shift flood control from passive response to active prevention,and provide solid support for national water security,water resources allocation,ecological protection,and food security.
