中文摘要 水流输沙能力是土壤侵蚀过程极其重要的参数之一,精确计算细沟水流输沙能力可以有效揭示细沟侵蚀过程机理,为建立坡面细沟侵蚀过程模型奠定重要基础。采用细沟水槽试验方法对黄土坡面细沟水流输沙能力变化特征进行研究。结果表明:不同坡度下,细沟水流输沙能力随流量增加而平缓增大,可用幂函数方程很好地描述;不同流量下,细沟水流输沙能力随坡度的增加而增大,可以用指数方程很好地描述;细沟水流输沙能力随流量及坡度变化的因子模型为二元幂函数方程,其中流量对细沟水流输沙能力的影响大于坡度的影响;ANSWERS模型中的输沙能力方程不能用于计算黄土陡坡细沟水流输沙能力。
英文摘要Water transport capacity is a very important parameter of soil erosion,accurately calculating it
which can reveal the mechanism of the process of rill erosion effectively and provide a significant basis for
establishing process-based model.In the paper,the variation of rill flow sediment transport capacity was
studied by a flume.Results showed that:(1)Rill flow sediment transport capacity increased smoothly with
flow discharge at different slope gradients and could be described by power equation;rill flow sediment transport
 capacity increased with slope gradient at different flow discharges and could be described by linear equation;
rill flow sediment transport capacity which varied with slope gradients and flow discharge could be described
 by a dual binary power function,the effect of flow discharge was greater than slope gradient in the
power function;ANSWERS model was not well predicted sediment transport capacity of sheet flow over
loess slope.
