| 摘 要： | 渭河下游及黄河潼关河段近年来河势发生了变化，从渭河及主要支流水沙、降雨、用水等方面，分析渭河水沙量衰减的原因及对渭、黄河的影响。经分析，渭河水沙量衰减的主要原因是流域降水量减少、用水量过度。渭河水沙量衰减是造成渭河下游及潼关河段河势发生变化的一个重要原因。

| Abstract: | The flow regime of the Wei River and the Yellow River has been changed in recent years. The water and sediment amounts, the precipitation and water use of the Wei River and its main tributaries were analyzed, and the cause and impacts of water and sediment amounts decreasing on flow regime of the Wei and the Yellow River were expounded. It was pointed out that water and sediment decreasing were mainly caused by precipitation decrease and water use increase. The main factor, casing the river regime change of the Wei River, was the decrease of water and sediment. |
