丹江口水库建成后，改变了天然河道的水沙输移条件，入库水沙受人工调度控制，进入了水库淤积重新造床过程，自建库至 2003 年，入库沙量 98 ％以上都淤积在库内，其中有 85 ％的淤积量都分布在干流库区内 , 出库的泥沙也都是异重流冲泻质。根据丹江口水库历史及近期资料，对汉江干流库区纵、横、垂 3 个方向的淤积分布进行了详细的分析研究，为三峡水库的运用提供良好的借鉴。

Since the construction of Danjiangkou Reservoir, the water and sediment transportation in the natural river course has been changed. The discharge and sediment into the Danjiangkou Reservoir was controlled by the reservoir operation, so the river bed was reformed within the reservoir area. From the completion of Danjiangkou Reservoir to 2003, more than 98% sediment load into the reservoir deposited, of which 85% was distributed in the reservoir area, wash load was released by reservoir. On the basis of the history and recent data of Danjiangkou Reservoir, the sediment distribution in three dimension of the Han River main stream reservoir area was analyzed in detail, this result may provide a better reference for Three Gorges Reservoir operation.
