摘要:
了解黄土丘陵区暴雨时空变化特征,有利于深入研究土壤侵蚀机理.利用雨量站控制条件较好的桥沟小流域资料,统计分析了该流域30min、60min、120min和150min时段降雨及次降雨空间变化的关系,时段降雨分布同次降雨分布的内在联系以及次降雨的时空变化过程.结果表明,当分析时段达到一定长度以后,时段降雨对次降雨分布具有一定的代表性;降雨空间变化程度的相关距离关系随距离的增加而减弱,从时间上看,暴雨中心位置是不断变化的.
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.
