| 摘 要： | 为了明确黄河北干流的径流变化规律以及和季风的关系,研究将黄河北干流划分为3个河段(上游:河口-吴堡、中游:吴堡-龙门,下游:龙门-潼关),并将时间尺度分为小尺度(<10 a)、中尺度(10～20 a)和大(≥20 a)尺度,应用该区域1919～2006年4个水文站的年天然径流数据、亚洲季风指数和踞风指数,采用线性回归和...

| Abstract: | Changes of runoff in Beiganliu area,the wide stretch of land of the north bank of the Yellow River,and the correlation with the climate change were studied.Field investigation was conducted in three sub-areas(the upstream,midstream and downstream of the Yellow River) involving collection of runoff and meteorological data for the period from 1919 to 2006.Runoff in time-series was analyzed by methods of regression and Mexico Hat wavelet transform.The result indicated that the runoff decreased remarkably durin... |
