为研究葛洲坝水库对长江水文系统复杂性的影响，采用多尺度熵理论对长江干流宜昌、汉口、大通3个主要控制水文站的径流量序列进行分析。结果表明：长江干流径流序列复杂度从上游到下游表现为逐渐增加趋势；葛洲坝水库蓄水对长江干流径流序列结构复杂性产生了一定的影响，改变了天然条件下的系统复杂度，改变程度随距离的增大而减弱。

In order to ascertain impacts of Gezhouba Reservoir on the complexity of the Yangtze River system, multi-scale entropy theory was applied to analyze the runoff series of main stream of Yangtze River at the three main hydrological stations, which are Yichang, Hankou and Datong.The results show that the complexity of the runoff series of main stream of Yangtze River show increasing trend from upstream to downstream;Gezhouba Reservoir has certain impact on the complexity of the runoff series of main stream of Yangtze River.It changes the level of the complexity of the system under natural conditions, which decreases with the distance getting further.
