Ecological slope protection is a kind of slope protection technology which integrates the basic knowledge of engineering mechanics, soil science, ecology and botany to support the slope or slope and form a comprehensive slope protection system composed of plants or engineering and plants. After the excavation slope is formed, the surface layer of the slope is protected and reinforced by planting plants and the interaction between plants, rock and soil (root anchoring effect), so that it can not only meet the requirements of slope surface stability, but also restore the damaged natural ecological environment. It is an effective method of slope protection and slope consolidation.
Function of ecological slope protection
(1) Slope protection function: vegetation has the function of deep root anchoring and shallow root reinforcement;
(2) Prevention of soil erosion: it can reduce the pore water pressure of slope, intercept rainfall, weaken splash erosion and control soil particle loss;
(3) Improve environmental function: vegetation can restore the damaged ecological environment, promote the degradation of organic pollutants, purify the air and regulate the microclimate.
