摘要
在降雨强度为50mm/h的条件下,在降雨10min后,在坡面初步形成细沟时,用电解质脉冲法对4种坡度的水流速度进行了测量。测量结果表明无论土壤表面是细漫流或细沟流,用这种方法均可进行测量。从理论上和拟合结果来看,这种方法测量水流速度是可行的。若进一步研究,有可能用于解释细沟侵蚀的机理。
Four types flow velocity are measured using electrolyte pulse method while rills are formed at slope, and when it rain for 10 minutes with intensity of 50 mm/h. The results show that the method is feasible to measure the velocity of sheet flow, no matter the rill is formed or not. The velocity of flow on soil surface can be measured and may be used to explain the mechanism of rill erosion.
