| 摘 要： | 介绍了轮次分析法的概念和负轮长的计算方法,并对黄河青铜峡水文站1922—1933年的12 a枯水段进行了分析,对其重现期进行了预测。结果表明:青铜峡站1723—2000年天然径流量的多年平均负轮长为1.976 a;连续12 a枯水段在整个天然年径流量系列中的重现期约为419 a。

| Abstract: | The concept of runs analysis method and the calculation method of negative run length were introduced in this article.As an example,the negative run length of the annual natural runoff series from 1723 to 2003 of Qingtongxia Hydrological Station was computed.The results show that the negative run length of the annual natural runoff series of Qingtongxia is 1.976 yrs;the return period of the continuous dry period of 12 yrs from 1922 to 1933 is about 419 yrs in the total series. |
