Abstract: To evaluate the protective effect of slope with vegelation and offer theoretical and technical references for the veg- etation restoration and reconstruction of side slopes on Baoteng Highway, the ecological effect of re-vegetation on Baolong Highway side slope is studied.This study is based on the restoration ecological principles of Baolong Highway side slope construction project. The results show that:①the selecticn of vegetation species should be focused on the native-based plant, and alien species with no strong invasive nature can also be selected ②bioengineering techniques for slope protec- tion have limitations and should be combined wih engineering technique;③the relatively steep slope of rock could be con- sidered to set planting trough within the box beam, planting climbers and hanging plants.
