Slope protection mechanism of three-dimensional vegetation network

　　The erosion resistance of vegetation is realized through its three main components: first, the growth layer of plants (including perianth, leaf sheath, leaf and stem), which can prevent the surface soil of slope from being directly eroded by rain through its own dense coverage, reduce the scouring energy of rainstorm runoff and surface runoff speed, thus reducing soil loss; The second layer is the humus layer (including the interface between the leaf litter layer and the rhizome), which provides a protective layer for the surface soil of the slope; The third layer is the root system layer, which provides mechanical stability by reinforcing and anchoring the surface soil of the slope. In general, during the early stages of plant growth, the root system formed by a single plant is only loosely tangled together without a long lying root system, making it easy to separate from the soil layer and unable to provide protection. The application of 3D mesh aims to achieve more thorough shallow protection by enhancing the effects of the above three aspects. One is to increase its protective and mechanical stability performance within a certain thickness range; Secondly, due to the existence of three-dimensional networks, the massive root systems of plants are connected to the mesh reinforcement of the three-dimensional network, forming a plate structure (equivalent to reinforcing the soil surface of the slope), thereby increasing the tensile and shear strength of the protective layer, limiting the expansion of the phenomenon of "gradual destruction" caused by erosion (erosion can directly damage individual plants, and over time, the damaged area increases), and restricting the occurrence of shallow sliding and uplift of the slope surface.
