摘要
为了研究晋西不同水土保持措施对流域产汇流机制的影响,选取山西省黄土丘陵区典型小流域王家沟小流域1990—2015年185场降雨资料,采用线性趋势分析法和相似对比法,分析探讨了3种水保措施对不同量级降雨量汇流机制的影响。结果表明:梯田对延长洪水历时没有明显影响,但会减小洪峰流量,对洪峰流量的减小值随着降雨量增大而减小;随着降雨量增大,植树造林对洪峰流量的衰减作用比对洪量的衰减作用显著;淤地坝对延长小降雨量级洪水历时作用显著。
In order to study the influence of different soil and water conservation measures in the west area of Shanxi Province to the runoff yield and concentration mechanism of the basin,185 events of rainfall data from 1990 to 2015 in the typical small watershed of Wangjiagou in the loess hilly region of Shanxi Province were selected and analyzed by linear trend analysis and similarity comparison.The impact of three types of water conseryation measures on different levels of rainfall convergence mechanism was discussed.The results show that the terraces have no obvious influence to the extension of flood duration,but will reduce the flood peak flow and the decrease of the flood peak flow decreases with the increase of rainfall;with the increase of rainfall amount,the function of afforestation on the attenuation of peak discharge is significantly greater than that of the flood volume;the warping dam has a significant effect on the extension of flood duration of small rainfall magnitude.
