摘要
针对黄河水资源短缺、干旱频发、旱灾损失大等重大问题,以应对干旱的黄河流域水资源调配为切入点,开展大型灌区旱情实时监测、应对干旱的径流洪水预报、大型梯级水库群优化调度以及干旱风险管理等关键技术研究,提出干旱评估与演变特征识别、灌区干旱实时监测、洪水/径流预报、多年调节水库旱限水位最优控制、水库多分期汛限水位优化、梯级水库群协同优化调度、干旱应对与风险管理等关键技术,形成大型灌区旱情实时监测、径流/洪水预报以及黄河梯级水库群调度等技术平台,集成黄河流域旱灾监测与预警、抗旱水源调度等综合技术体系框架,实现黄河流域干旱的有序应对,显著提升应对干旱的黄河水资源调配技术水平。
Aiming at the major problems of water resources shortage,frequent drought and huge loss by drought disasters,etc.,taking water resources allocation for drought of the Yellow River basin as an entry point,the key technology studies on real-time drought monitoring of large irrigation area,flood / runoff forecasting for drought,optimal operation of large cascade reservoirs and drought risk management have been conducted. The key technologies such as drought assessment and characteristics identification,real-time drought monitoring of irrigation area,flood / runoff forecasting for drought,optimal control of drought limit water level for multi-year regulating storage reservoir,optimal study on more stage flood control level,the collaborative optimization dispatching of cascade reservoirs and drought risk management have been created. The technology platforms of real-time drought monitoring of large irrigation area,flood and runoff forecast for drought and optimal dispatching of large cascade reservoirs,drought monitoring and early warning for the Yellow River basin and optimal dispatching of water sources for drought have been integrated,which realizes the coping with drought orderly and promotes the water resources allocation technology level for drought of the Yellow River basin significantly.
