考虑未来水资源配置的龙刘水库可调水量研究

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。

Transferable Water of Longyangxia-Liujiaxia Reservoirs Taking into Account of Water Resources Allocation in the Future

Aiming at the deterioration of relation between water and sediment and aggravated contradiction between water supply and demand in the upper reach of Yellow River, according to the results of “Water Resource Allocation of the Yellow River Basin (2012-2030)”, the transferable water based on cascade reservoirs operation in the upper Yellow River were studied. Using Longyangxia and Liujiaxia as regulation, joint operation model of water and sediment regulation was established by considering water supply and ice and flood control in the whole basin. Then, 13 schemes were set in four scenarios and four modes, and the results were obtained by Self-Iteration Simulation and Optimization Algorithm (SSOA). Finally, the result in the mode of regulating power generation by water supply turned out to be the best. It showed that the transferable water will decrease and the water transfer projects almost have no effects on transferable water of cascade reservoirs with the increase of water demand in the future. The results provide an important reference for water and sediment regulation and technological support for planning and scheduling cascade reservoirs at the upper reach of Yellow River.
