摘　　要：小浪底水库的投入运用大大减轻了三门峡水库对于黄河下游防洪、防凌的负担 ,但远不能彻底解除。三门峡水库在不影响潼关河床高程、维持槽库容冲淤平衡及有利于黄河下游减淤的前提下 ,应当配合小浪底水库充分发挥它们的综合利用效益。经研究 ,适当抬高每年 3～ 5月库水位 ,利用桃汛后期洪水将库水位从315m抬至 319m ,则在净增加两库总发电量的同时 ,对潼关河床高程在丰水年比目前水平低的情况下仍无不利影响。若将库水位抬至 32 1m ,则对目前水平的潼关河床高程基本上也无不利影响。On the premise that the bed level at Tongguan Station is not affected, the channel volume of reservoir is kept in equilibrium between deposition and erosion, and the deposition in the Lower Yellow River is not increased, the comprehensive usage should be given into full play in united operation of Sanmenxia and Xiaolangdi Reservoir. If the water level of the Sanmenxia Reservoir in April is raised from 315m to 319m every year, the total hydropower for two projects will be increased. Meanwhile, the bed level at Tongguan Station is not raised even if it is lower before.
