 Based on the theory of adapting to ecology, we should respect nature, face up to nature, protect nature, restore nature, give consideration to ecological benefit, economic benefit and social benefit, so as to achieve the evergreen four seasons and reflect the landscape effect with local characteristics. At the same time, in selecting plant species, we should insist on biodiversity, multi-family combination, tree, shrub, grass combination, construction of trees, irrigation, grass combination, multi-tree species, multi-structure, multi-function multi-layer ecological landscape community, effectively increase green quantity and green leaf area, The potential ecological force per unit area was excavated and the leaf area index was increased. The line changes and rhythm in the whole greening area should be paid attention to. However, based on the consideration of climate, soil and site types, preference should be given to tree species and lawn cover plants that are resistant to drought, barren, pollution and pollution, which can not only adapt to local land conditions but also meet the requirements of highway greening. Achieve the unity of function, art and science. In the cutting slope (upper slope), we should adopt the mixed planting technique of different grass seeds or grasses, mix annual herbs with perennial herbs, and then mix a certain proportion of shrubs or small trees. At first, annual herbaceous plants grow rapidly, soil and slope protection, to prevent erosion effect is obvious. After that, perennial herbs and shrubs or small trees became dominant species, and the function of soil and slope protection and landscape were further strengthened. Embankment slope (lower slope) should choose perennial, cold, drought, barren, strong growth potential, strong regeneration ability of grass.
