摘　　要：为研究植被根系含量对岩质边坡表层抗冲刷性的影响,通过根系含量与粘聚力增加值关系建立了根系密度与土壤抗剪强度的关系式,推导了根系分布密度的土壤临界切应力,进而推算客土层滑动面范围内的单位体积含根量。最后,选取实例研究植被根系含量对岩质边坡表层抗冲刷性的影响,为边坡选择最适合的绿化草种和单位面积的播种数量提供有效依据。According to the vegetation root content on rock slope surface erosion resistance, the relation of root density and the soil shear strength was established by the relation between root content. Furthermore, we use the added value of cohesive force to derive the soil critical shearing stress and consider the root distribution density. We also calculate per unit volume root content in the scope of sliding surface about soil layer. The selected experiment and analysis shows that vegetation root content on the rock slope surface erosion resistance for the slope chooses the most suitable greening grass and the seeding quantity of per unit area to provide basis effectively.
