摘　　要：为分析人类活动对汉江泥沙特性的影响，以白河、皇庄和仙桃三个水文站为例，以丹江口水库关闸蓄水时间划分研究时段，利用1955-2006年的日流量和日含沙量资料对比分析了研究时段内汉江中下游年、汛期、非汛期、月输沙量及水沙关系的变化特性。结果表明，丹江口水库的运行对其下游年、汛期、非汛期输沙量、输沙量年内分配及水沙关系的变化特性均有显著的影响。With the Baihe, H uangzhuang and Xiantao hydrological stations as the study objectives for researching of the impact of human activities on the sediment regime of the Hanjiang River, the study period was divided into two subperiods by the time when the gates of Danjiangkou reservoir was initially closed for water storage. The variations of annual, monthly sediment food, the sediment load of wet season and dry season, and the relation between runoff and sediment of the Hanjiang River were comparatively analyzed according to the observed data of daily discharge and sediment during 1955 to 2006. The result shows that the operation of Danjiangkou reservoir have significant influences on annual sediment load, the sediment load of wet season and dry season, the relation between runoff and sediment, and the monthly distribution of sediment load downstream.
