It is reported that the slope of China's slope is generally 45. Although simple herbaceous plants have large coverage and beautiful appearance, the protective effect is not ideal. However, planting trees will increase the load on the slope surface. It is easy to cause slopes under the action of wind power. Stable or collapsed. With the improvement of practical experience, people gradually realized the unique advantages of shrub landscaping. Shrubs not only have good advantages of drought resistance, water retention, soil conservation, sand prevention, dustfall, salt and alkali resistance, but also have fast growth, poor tolerance, and low requirement for soil environment. Compared with herbaceous plants, the advantages are quite obvious. However, a single shrub community is also prone to topsoil erosion, which is detrimental to the initial soil and water conservation. Therefore, in the process of slope protection, the choice of plant species should be based on the combination of herbaceous plants and shrubs, and the combination of the two can provide a fast and lasting slope protection effect.
