| 摘 要： | 潼关高程在历史时期是上升的，三门峡水库建成后上升加剧，工程改建后，稳定在326．64m。1986年以来，潼关高程上升原因有：降雨量偏估；龙、刘两库,蓄水使进入潼关水量减少；水保工程和用水增加等引起潼闫上下游河道淤积促使潼关高程上升；改善潼关高程应采取综合治理，多途径处理泥沙问题。

| Abstract: | Tongguan elevation was raised gradually during the historic period, but the raising speed was accelerated after construction of the Sanmenxia reservoir, and stabilizing at 326.64m after its reconstruction. Since 1986, there are several factors which influence the river bed elevation: lower rainfall, decrease of incoming flow at Tongguan, since Longyangxia reservoir and Liujiaxia reservoir storage of water, serious deposition increasing in upstream and downstream reaches at Tongguan due to water and soil conservation project and development of diverting works. To control the bed elevation at Tongguan , comprehensive measures should be taken to solve deposition of sediment. |
