soil loss amount

This thesis is to modify the calculating model of soil erodibility ( K factor), one of the most important factors of universal soil loss equation, which is widely used in the prediction of soil loss amount of highway slope in Hubei Province.

本论文即对目前广泛应用于湖北省高速公路边坡水土流失量预测的美国通用土壤流失方程中的主要因子之一，土壤可蚀性因子K的计算模型进行修正。

With artificial simulative washing test, the effects of soil potassium loss in loess area by fertilizing KCl, vegetation coverage, and amount of rainfall were preliminarily studied.

通过人工模拟冲刷试验，初步分析了施KCl、植被覆盖度和降雨量对黄土区土壤钾素径流的影响。

In this thesis, with eight events of artificial water-washing test on five different slope gradients, factors affecting soil potassium loss by erosion, such as slope gradient, rain intensity, vegetation coverage, and amount of rainfall are discussed.

本文通过在5个不同坡度径流小区进行的8次人工模拟冲刷试验，探讨了坡度、放水冲刷强度、植被和降雨量等因素对土壤钾素径流流失的影响。

In addition water loss in transpiration of plants is also affected by the content of soil moisture and the amount of precipitation.

蒸腾耗水量还受土壤湿度、降雨量的影响。

There is no erosion occured if there have no heavy storm and the forest coverage of 60% has important role to reduce soil loss amount.

一般在无大暴雨情况下基本不发生水土流失，且60%的林分覆盖度对减少土壤侵蚀量的作用显著。
