摘要
根据黄河源区水土流失现状,用人工降水方法,通过场降雨溅蚀实验,分析在不同雨强和坡度情况下对土壤溅蚀的影响。结果表明降雨强度是影响溅蚀的显著因子,溅蚀量与雨强和坡度呈正相关关系,结皮土壤具有一定抗溅蚀作用。
According to the present situation of soil erosion in Yellow River source region,this article analyzed the influence of the rainfall intensity and slope in different level on soil erosion by the rainfall splashing erosion experiment in artificial precipitation.The result showed:the rainfall intensity was the significance factor to affect the quantity of rain splashing erosion.The rain splashing erosion quantity was positive relationship with the rainfall intensity and slope. Soil crust was against the soil splashing erosion from rain splashing erosion.
