| 摘 要： | 采用重新标度极差分析法(R/S分析方法),对石羊河流域8条河流的年径流序列进行了变异诊断,计算了变异前后序列均值和年径流随时间的变化关系。结果表明,石羊河流域8条河流的年径流序列已发生了变异,变异年份分别为:杂木河1989年,西营河1989年,金塔河1973年,黄羊河1982年,古浪河1984年,大靖河1959年,东大河1967年,西大河1960年。经回归分析表明,对这些变异年份的诊断是合理的。

| Abstract: | The article deals with researches on the hydrologic sequence of Shiyang River basin.The aberrance point of the hydrologic sequence were found out by using R/S (Rescaled Range Analysis) method for all eight branches.The average values of annual runoff sequence at fore-and-aft changes were calculated.The equations of annual runoff sequence and time were regressed.As an example,aberrance happened in the annual runoff sequence of Shiyang River,basin's 8 branchs,and the aberrance point was:Zamu River,1989;Xiying River,1989;Jinta River,1973;Huangyang River,1982;Gulang River,1984;Dajing River,1959;Dongda River,1967;Xida River,1960.The result is rational. |
