| 摘 要： | 对缓坡地在土壤饱和情形下土壤溶质的流失过程进行了室内模拟实验,研究结果表明,在缓坡地,只考虑坡地上方来水对饱和土壤的作用,土壤溶质、水土的流失过程更适合采用幂函数来描述,而且溶质受土壤吸附的特性也影响其流失速率,但并不影响其流失过程的规律性。

Soil Solute Transportation under Saturated and Gentle Slope |
| |
| Abstract: | In the case of soil saturated and gentle slope,a series of indoor simulated experiments were conducted for the law of soil solute transport.Results show that power function is more suited to describe the process of the transportation of soil solute and soil eroded considering only for saturated soil affected by water from upper end of gentle slope,and the characteristics of soil solute adsorbed by soil can affect its loss rate,but does not affect the law of its transportation process. |

| Keywords: | saturated soil transportation of soil solute power function |
