摘　　要：随着长江流域水资源开发利用程度的提高以及全球气候的变化,长江径流特性在一定程度上发生了变化.为分析人类活动对长江径流特性的影响,以万县、宜昌、汉口、大通、白河、仙桃6个水文站为研究对象,以丹江口、葛洲坝及三峡水库关闸蓄水时间划分研究时段,利用各站近50 a的日流量资料对比分析了各研究时段长江年、汛期、非汛期、月径流量变化特性.结果表明,水库对河流径流量的影响与水库库容大小、水库运行方式以及测站与水库的距离远近有关.With the development and utilization of water resources of the Yangtze River and the change of global climate, the characteristics of the runoff of this region have changed to some extent. With the Wanxian, Yichang, Hankou, Datong, Baihe and Xiantao hydrological stations as the study objectives for research of the influences of human activities on the runoff of the Yangtze River, the study period was divided into 4 subperiods by the time when the gates of Danjiangkou, Gezhouba, and Three Gorges reservoirs were initially closed for water storage. The variations of annual runoff, monthly runoff, and the runoff of wet season and dry season of the Yangtze River were comparatively analyzed according to the observed data of daily runoff for recent 50 years, and the result shows that the impacts of reservoirs on river flow regime vary with the capacity and operation pattern of reservoirs and their distance to the measurement stations.
