摘要

针对长江中下游近50年来部分水文断面如螺山、城陵矶洪水位抬升明显、高洪水位持续时间加长的问题,统计了大量水位、流量、水流含沙量以及河床地形等实测资料,并进行分析计算.结果表明,长江中下游洪水位变化与河段河床演变及河道形态变化密切相关,江湖淤积及河道形态变化是造成洪水位抬高及高洪水位持续时间加长的主要原因.
In consideration of the fact that the flood water level of some hydrological sections on the middle and lower Yangtze River, such as the Luoshan section and the Chenglingji section, has been raised sharply, and the duration of high water level has been prolonged during the past 50 years, a statistical calculation and analysis was made of a great deal of measured data about water level, flow rate, sediment concentration, bed configuration, and etc. The result shows that the variation of flood water level on the middle and lower Yangtze River is closely related to river bed evolution, and that the river bed deposition and variation of channel configuration are the main reasons of water level rise and long duration of high water level.
