摘　　要：本文作者在实地观测资料的基础上,分析了降水量、雨强、土壤入渗及不同植被对水土流失的影响,认为雨强是影响径流速率的主导因子,雨量是影响径流量的关键,建造植被、增强土壤入渗是防止水土流失的有效途径。The effects of rainfall,rainfall intensity,soil permeability and vegetation types on soil and water loss were analysed in the paper on the basis of observed data in experiment plots. The results of the experiment showed that the rainfall intensity is the leading factor influencing runoff rate,and the rainfall is the key influencing runoff volume, Therefore, to build vegetation and strengthen soil permeability are an effective way for averting soil and water loss.
