To solve the ecological restoration problem of high steep hard slopes

the characteristics and ecological protection difficulties of high steep hard slopes are analyzed.Based on the natural conditions of Nanning pumped storage power station project area

the ecological protection technology scheme of jointly adopting drilling

geogrid

sprayed granular soil

high-performance ecological substrate and reinforced MacMat is proposed

and the implementation plan is formulated.The soil erosion prevention and control effect of this plan is good

which has effectively achieved vegetation restoration on high steep hard slopes.
