摘要
依据大量的实测资料,分析了长江中下游近50年来的洪水位变化与河床冲淤变化,发现部分水文断面洪水位抬升明显、高洪水位持续时间加长的现象,与河段河床演变及河道形态变化密切相关,为长江中下游洪水抬升机理分析提供了重要的依据。
Based on a large number of field data, the paper has analyzed the flood level and bed level variation at the middle and lower stream of the Yangtze River in recent 50 years. It has been found that there is close relation between the river variation and the going-up and keeping-longtime phenomenon of flood water level. The paper will offer an important basis to the influence factor on higher flood level.
