摘要
本文应用水文随机模拟方法,对长江宜昌站年悬移质输沙量均值进行了抽样误差估计,并用其它三种方法分析了均值的变化范围.结果表明,宜昌站多年平均输沙量是较稳定的.
In this paper, the sampling error on the mean of annual suspended sediment discharge for the Yichang station on the Yangtze River has been estimated by use of the hydrologic stochastic simulation, and the variation ranges of the mean have been analysed by other three methods. The results show that the annual average sediment discharge for the Yichang Station is stable.
