摘　　要：根据试验小区观测资料,本文分析了降雨量,雨强,土壤渗透及植物对水土流失的影响,结果表明:雨强是影响径流强度的主导因子,雨量是决定径流量的关键。建立植被,增强土壤入渗能力是防止水土流失的有效途径。On the basis of observed data from experiment plots,We analy- sed the effects of rainfall,rainfall intensity,soil permeability and plants on water and soil loss.It was suggested that rainfall inten- sity is a leading factor to runoff intensity;rainfall is a key to in- fluence runoff volume,To build vegetation and strengthen soil per- meability is an effective way for avoid soil and water loss.
