黑土坡面径流特征模拟研究
Simulation Study on Runoff Characteristics of Slope in Black Soil
摘要
Abstract
Runoff parameters of black soil slope were analyzed depending on artificial rainfall simulation experiment .The results show that on black soil slope,initial runoff production time was shortened,and runoff amount and runoff coefficient were increased as rainfall intensity and slope increased .On pre-rain-fall conditions,runoff erosion characteristics of the second rainfall were stronger than the first rainfall . The time of rill forming was shortened as slope increased .When the slope was increased to 1 5°,rill gen-erated at approximately the same time,amount,length,width and depth of rill were increased along with the increase of slope,and the effect of slope gradient on deposition was greater than rainfall intensity .关键词
