How do trees prevent soil erosion?

1. The prevention and control of soil and water loss by plants is mainly realized through the mechanical action of roots, the hydrological action of stems and leaves and the transpiration and drainage action of plants.

Secondly, through the net bag effect or anchoring effect between plant roots, the cohesion between plant roots and soil can be enhanced, and the anti-erosion ability of soil can be enhanced, so that the soil can cause the erosion of surface runoff and maintain soil erosion.

Thirdly, the leafy canopy can effectively prevent raindrops from splashing directly on the surface and form secondary rainfall in the forest, thus effectively preventing the surface soil from being splashed.

Four, trees can form a benign local microclimate, enhance the ability of soil to conserve water and prevent soil erosion.
