| 摘 要： | 定量研究上游水库拦沙效应是揭示三峡入库水沙条件变化的关键之一.本文分析了长江上游12000多座水库拦沙对三峡水库来沙量减少的影响,并预测在建、拟建水库运行后三峡入库沙量变化趋势.结果表明,1991-2005年三峡上游水库群年均拦沙约18000万t,其中嘉陵江和金沙江流域水库群的年均拦沙量分别为6010万t和5000万t... |

| Abstract: | Construction of reservoirs in the upper Yangtze River(Changjiang) has great impact on the incoming flow and sediment conditions of the Three Gorges reservoir(TGR).This paper analyzes the impact of 12000 reservoirs in the upper Yangtze on the sediment inflow to TGR,and predicts the trend of incoming sediment for the case of all the cascade reservoirs at their operation stage.Results show that about 180 millions ton(Mt) of sediment was trapped annually by these reservoirs in 1991-2005 and that about 60.1 Mt /... |
| Keywords: | river sediment engineering Three Gorges reservoir decrease of incoming sediment sediment deposition reservoirs on the upper reaches of Yangtze River |
