| 摘 要： | 通过上方供水方式模拟薄层水流,研究了流量对红壤坡面产流、产沙及非吸附性离子（Br^-）迁移过程特征的影响。结果表明,起始产流时间随着流量的增加呈幂函数递减趋势;不同上方供水流量所形成的径流量随时间变化规律相似,初期产流量迅速增大而后期趋于稳定,但径流量随着上方来水流量增大而增大。在消除雨滴击溅夯实作用下,随着上方来水流...

| Abstract: | By supplying water from upslope to simulate shallow flow,the simulated experiments were used to quantify the effects of flow rates on runoff,soil erosion processes and the transport processes of Bromine,non-adsorption ion,on slope red soil.The results showed that the initial time of runoff decreased by power function with the increase in flow rates.The variation of runoff rates with time was similar at different flow rates.In the initial stage of runoff,runoff rates increased rapidly and then became stabili... |
