摘要:
采用室内人工模拟降雨方法,研究不同坡形坡面侵蚀规律.结果表明产流量和含沙量、总径流量和侵蚀量大体上是凹形坡大于凸形坡,其次是内聚直坡,直线形坡最小,并且随着雨强和坡度的增大而增大.坡面上部和坡脚侵蚀较弱,坡面侵蚀的剧烈段在坡面中下部,并随雨强和坡度增大而逐渐上移.细沟的宽度和深度随雨强的增大而增大,产生细沟后侵蚀量将迅速增大,最大占总侵蚀量的91%.
Abstract:
The soil erosion of different slopes is studied by simulating rainfall.The results indicate that amounts of runoff and sediment content,total runoff and erosion is concave type slope>male slope>cohesion slope>straight line slope,moreover,which is stronger with rainfall intensity and slope gradient.The erosion is weak on upper part and slope foot,and strong in middle lower part.Rill width and depth become bigger with rainfall intensity,erosion amount promptly enhances after rill appears,accounts for 91%.
