The anti-erosion effect of vegetation is achieved through its three main components: first, the growth layer of plants (including bracts, sheaths, leaves, and stems), which prevents the superficial soil of the slope from being directly eroded by rainwater through its dense coverage, reducing the scouring energy of heavy rainfall runoff and the velocity of surface runoff.The third layer is the root zone, which reinforces and anchors the soil on the slope's surface, providing mechanical stability. Generally, during the early stage of plant growth, the roots formed by individual plants are loosely intertwined without long horizontal roots, making them prone to separation from the soil layer and failing to serve as a protective barrier. The three-dimensional vegetation net slope protection technology combines the advantages of geotextile nets and vegetation slope protection, thus serving as a composite slope protection. Once the vegetation coverage rate on the slope exceeds 30%, it can withstand the erosion from light rain.With coverage rates exceeding 80%, it can withstand the scouring of heavy rain. As the plants grow lush, the runoff velocity that can be resisted reaches 6m/s, more than double that of ordinary turf. The presence of geotextile nets effectively reduces soil moisture evaporation on the slopes and increases infiltration. Additionally, due to the black, heat-absorbing properties of the geotextile material, it promotes seed germination and is beneficial for plant growth. The application of three-dimensional nets is to enhance the effects of the above three aspects for more comprehensive shallow protection. Firstly, within a certain thickness range, it increases its protective and mechanical stability properties; secondly, due to the presence of the three-dimensional nets, the extensive root systems of the plants are interconnected with the mesh structure of the nets.Form a panel structure (equivalent to reinforcing the soil surface of the slope), thereby enhancing the tensile and shear strength of the protective layer, and limiting the expansion of the "gradual destruction" phenomenon caused by erosion (erosion can directly damage individual plants, and over time, the damaged area increases). Ultimately, this limits the occurrence of shallow surface sliding and upheaval on the slope. Consequently, it reduces soil loss; secondly, the humus layer (including the interface between the leaf litter layer and the root stem), provides a protective layer for the soil surface of the slope.
