Description

A protection method for anti-erosion and ecological restoration of rock and soil slopes

technical field

The invention relates to the field of ecological restoration and protection of slopes, in particular to a method for anti-erosion and ecological restoration and protection of rock and soil slopes.

Background technique

For the rock-soil slope, it contains both soil components and some rock-sand particles, forming a sandy soil granular soil body. Because the rock-soil particles are loose and have no cohesion, the surface soil layer of the slope is very heavy under the action of rainfall erosion. It is easy to lose, so the vegetation on it is difficult to grow and survive stably. At the same time, due to the poor water storage capacity of the slope, it is difficult for the plants growing on it to obtain enough water for growth, and it is difficult to supply sufficient water to the roots of the slope plants simply by spraying or watering. In addition, in the prior art, how to uniformly plant vegetation on a slope in a large area is also a topic that requires further research.
