| 英文摘要 | Based on the data from the Yellow River and its tributaries in the Loess Plateau, a study of the spatial differentiation of hyperconcentrated flows frequency is made, also the relation between hyperconcentrated flows frequency and influencing factors is analyzed. The results show that the high-frequency zone of hyperconcentrated flows shows itself a shape of strip, with the northeast southwest direction. There are three high-frequency centers in the strip. They are at latitude 40°N, 36°N and 34°N. It seems that different factors have different effects to cause the hyperconcentrated flows. The result of the multiple-factor regression analysis shows that the efficiency of shrub, dry-land fields in hilly, woodland, loess thickness and mean annual precipitation to the hyperconcentrated flows are 16.6%, 4.4%, 6.5%, 29.7% and 42.8%, respectively. |
