基于全栈国产化珠江防汛抗旱"四预"体系关键技术研究及实践OA

To address the core questions of the complex flood and drought disaster prevention system in the Pearl River Basin,including prediction accuracy,data governance,dispatch simulation,and network security,and to achieve technological autonomy and controllability in core technologies,a"Four Pre"platform for flood control and drought relief in the Pearl River was built based on a full-stack domestic-substitution software and hardware environment comprising Kunpeng chips,Taishan servers,KylinOS,and Dameng Database.The platform integrated flood control,drought relief,salt tide prevention,and storm surge prevention.Through the development of a full-chain secure operation system,multi-model precise forecasting technology,and an AI-enabled scheme for"Four Pre"operations,the complete chain from data collection,data governance,model construction,simulation,and decision deduction to security protection was subject to technological autonomy and controllability.Independently developed code accounted for more than 90％of the platform's core code.The main technological achievements of the platform have formed a replicable and scalable Pearl River solution,which provides an important technical reference and practical experience for the domestic-substitution development of digital twin water conservancy systems.
