At present,with the rapid development of social economy,people''s awareness of environmental protection continues to increase,and environmental construction and environmental protection work are put on the agenda.Highway slope greening protection is an important means to achieve social sustainable development.Developed countries carried out research earlier in this area,and China''s research in this area started later.In engineering construction,ecological protection is to realize slope reinforcement and slope protection depending on the water storage and soil fixation effects of vegetation.Its slope protection can be summarized as the mechanical effect of root system and the hydrological effect of vegetation.As a basic form of slope greening protection,it is necessary for us to understand the mechanism of ecological protection and to enhance the design of ecological protection accordingly.Based on this,the article analyzed the development of slope greening protection technology and ecological protection mechanism from different angles,so as to establish a theoretical framework for future research.
