摘　　要：作者首先对潼关高程在历史上、建库前和建库后的变化过程进行了总结 ,分析了导致各个时期潼关高程变化的原因。然后利用具有较强理论基础且得到广泛应用的非均匀不平衡输沙数学模型对水库在不同运用方式和不同来水来沙条件下潼关高程未来的变化趋势进行了计算分析 ,对潼关高程下降的可能性和幅度提出了看法。Brief summary on the evolution processes of water level at Tongguan in history, before and after the build of Sanmenxia reservoir is firstly described. Reasons resulting in the change of water level at Tongguan in different periods are then analyzed. Results indicate that the water level at Tongguan is affected by both reservoir operation and oncoming flow and sediment. Finally, a well developed mathematical model is used to simulate the possible trend of the water level at Tongguan under different reservoir operations and oncoming flow series.
