中文摘要	为了根治内蒙古河段二级悬河问题,以黄河上游沙漠宽谷河段为研究对象,以龙羊峡、刘家峡为调控主体,开展黄河上游水沙调控研究。建立了输沙量、发电量最大的单目标模型以及多目标模型;分别采用自迭代模拟算法、逐次逼近动态规划算法(DPSA)和改进的非支配排序遗传优化算法(NSGA-II)求解模型;设置了初始、常规、优化和联合优化4种方案。通过实例计算,联合优化调度方案的区间总冲刷量达到了0.38亿t,梯级发电量148.22亿kW·h。表明该方案以较小的电量损失换来了输沙量的大幅度增加,水沙调控效果显著,推荐为最优方案。研究成果量化了水沙调控效果和各目标间的转化规律,为开展黄河上游水沙调控提供了决策依据,具有重要的应用价值和实际指导意义。
英文摘要	The regulation of water and sediment in the Upper Yellow River is studied in this paper. To eliminate the secondary suspended river that has formed in Inner Mongolia, desert valley reaches in the Upper Yellow River were studied and Longyangxia and Liujiaxia cascade reservoirs were chosen as subjects. Single objective models of sediment discharge maximization and generated energy maximization and a multi objective model were established and solved using a self-iteration simulation algorithm, successive approximation dynamic programming (DPSA), and an improved non-dominated sorting genetic algorithm (NSGA). Then initial schemes, routine schemes, optimization schemes, and joint optimization operation schemes were set. The results demonstrated that the total scouring sediment of joint optimization schemes was 38 million tons, and power generation of the cascade was 14.8 billion kW·h, with a small loss of power generation in exchange for a substantial increases in sediment. This indicated the great effort required for sediment regulation and the joint operation schemes was recommended as the best option. The results quantified the water and sediment regulation effects and transformation law between objectives are shown. Moreover, the achievements provide a basis for decisions regarding the regulation of water and sediment in the Upper Yellow River. They may have important applications and practical significance in this type of regulation.
