基于对高盖度斜坡进行调查、分析、研究，得出高盖度斜坡发育有强大的大孔隙系统。在强降雨事件下，雨水通过大孔隙系统形成优先流，继而发育孔隙堵塞带以形成局部隔水屏障，最终形成上层滞水。植被护坡原理在于其根系锚固地表土体，但根系有效锚固深度一般介于地表以下1~3 m，浅层滑坡的滑动面一般都在地表以下3~4 m，故其锚固效果有限。对于高盖度斜坡，在强降雨事件下，由于水力耦合作用，将会形成斜坡群滑现象甚至诱发泥石流等地质灾害。系统研究强降雨条件下斜坡盖度与斜坡稳定之间的关系不仅可以强化斜坡稳定理论，同时也为区域性山地灾害的预警提供科学依据。

Based on the analysis of slope with a high coverage,we obtained that its development has a strong cover macropore system. As the reason of heavy rainfall,the rain through the macropore system formed preferential flow, and then developed to form pores clogged with local impermeable barrier,and ultimately result in the formation of perched water vegetation protection principles in its roots anchor the soil surface. But its anchorage depth is limited , typically between roots effective anchorage depth of one-three meters below the surface,the sliding surface of shallow landslides are generally thirty-four meters below the surface,so the anchoring effect is limited. For the high-degree slope covered in heavy rainfall events,hydraulic coupling will induce a slippery slope group phenomenon even landslides and other geological disasters. Research the relationship between heavy rainfall and slope stability slope in system cover can not only strengthen the slope stability theory,but also provide scientific basis for a regional early warning mountain hazards.
