| 摘 要： | 在坡面径流泥沙计算中，传统的计算方法误将土壤中的孔隙水当作坡面径流来计算，从而不能准确反映土壤侵蚀状况。通过研究分析径流小区资料，提出了计算坡面径流泥沙的新方法。计算结果比较表明，两种方法计算结果的误差较大，且随着含沙量的增大误差在加大，此种现象应引起研究者的关注。

New Research for Slope Runoff and Sediment Calculation Method |
| |
| Abstract: | Soil moisture is traditionally calculated as slope runoff by mistake in slope runoff and sediment calculation, which can not accurately reflect real soil erosion status. A new method for calculating slope runoff and sediment is put forward in the paper through study and analysis of runoff plot data. The study and comparison results show that there are big error between the mentioned two calculations and the error is increased along with sediment concentration increase, to which researchers should pay attention. |
