论文针对黄河上游水沙关系恶化、水资源供需矛盾加剧等问题,围绕黄河全流域2012—2030年水资源规划的配置结果,以龙羊峡、刘家峡梯级水库联合调度为调控手段,考虑全流域综合供水、防洪、防凌、水资源供需平衡等要求,构建了黄河上游龙羊峡、刘家峡(龙刘)梯级水库联合调度模型,采用自迭代模拟优化算法,分别计算4种情景、4种模式下13个方案的可调水量,最终推荐以水定电模式下的计算结果为最佳模式。结果表明:随着未来需水量的增加,可调水量呈减小趋势,且调水工程的引水量未提高梯级水库的可调水量。研究成果可为黄河上游宽谷河段水沙调控、黄河上游梯级水库群科学规划和调度提供技术支撑。
In view of the deterioration of water and sediment relationship and the conflict between supply and demand of water resources in the upper reaches of the Yellow River, the dissertation focuses on the allocation of water resources planning in the whole basin of Yellow River between 2012 and 2030 and the joint regulation of Longyangxia and Liujiaxia cascaded reservoirs, (Long Liu) cascade reservoirs in the upper reaches of the Yellow River, the self-iterative simulation optimization algorithm was used to calculate four kinds of scenarios respectively, and four kinds of scenarios were calculated under the four models A program of adjustable water, the final recommendation of the water power mode calculation results for the best mode. The results show that with the increase of future water demand, the amount of water available for adjustment shows a decreasing trend, and the water diversion project does not increase the water capacity of cascade reservoirs. The research results may provide technical support for the regulation of water and sediment in the broad reach of the upper Yellow River and the scientific planning and scheduling of cascade reservoirs in the upper reaches of the Yellow River.
