The anti-erosion effect of the three-dimensional vegetation net is achieved through its three main components: Firstly, the growth layer of plants (including sepals, sheaths, leaves, and stems), which prevents the surface soil of the slope from being directly eroded by rainwater through its dense coverage, reducing the scouring energy of heavy rain runoff and the speed of surface runoff, thereby reducing soil loss; secondly, the humus layer (including the interface between fallen leaves and the root system), which provides a protective layer for the surface soil of the slope; and thirdly, the root system layer, which reinforces and anchors the surface soil of the slope, providing mechanical stability. Generally, in the early stages of plant growth, due to the loose intertwining of individual plant roots without long-laying roots, they are prone to separation from the soil layer and fail to provide protection. The application of the three-dimensional net precisely enhances the effects of these three aspects to achieve more comprehensive shallow soil protection.
