| 摘 要： | 利用宜昌站实测径流资料,对年最大选样法和超定量选样法进行比较,两种选样方法简便易算,超定量选样法可从有限的洪水资料中利用更多的洪水信息。在进行洪水频率分析前,检验样本系列的独立性,并利用常用的线型优选方法选择合适的频率线型。结果表明,超定量选样法在设计洪水计算中的结果是可靠的。

| Abstract: | According to the observed data of Yichang station, annual maximum sampling method and peaks over threshold method (POT) is compared. Both of two methods are simple and easy to be implemented. The POT method can use more flood information from limited flood data. Before analyzing flood frequency, we should ensure independence of the sampling and choose appropriate frequency line-type with common optimal method. The results show that the POT method is reliable for design flood calculation. |
