- Abstract:
- In order to better understand the temporal and spatial characteristics of rainstorm in loess hilly region,using small watershed data of Qiaogou,the relationship between 30 min,60 min,120 min,150 min period and rainfall were statistically analyzed.Furthermore,the temporal and spatial variations of rainfall and the intrinsically link between rainfall and period rainfall were studied.The results showed that when the period reaches a certain length,the rainfall is distributed fairly representatively by period rainfall;With the increasing of distance,the relativity of rainfall between rainfall stations weakened.With the change of time,the center location of rainstorm is constantly changing.All the results were useful to understand the mechanism of soil erosion further in-depth.
