Recovery method of bare red sandstone abrupt slope vegetation

Abstract

The invention relates to a recovery method of bare red sandstone abrupt slope vegetation, which comprises the steps of: preparing an abrupt slope; preparing grass square lattices; distributing and fixing the grass square lattices in an interlaced way along the abrupt slope; preparing plants growing base material with soil, sand and fertilizer; filling the plants growing base material into nutrition bags; growing herbal and shrub plants in the growing base material; digging growing points in the grass square lattices; and embedding the nutrition bags and the herbal and shrub plants into the growing points together. By adopting the method, the grass square lattices and slope soil layers are jointly formed into a protection system of the abrupt slope, thereby effectively preventing the abrupt slope from being directly splashed by raindrops to avoid that the surface of the ground is washed by radial flow and play an important part in the stabilization of the abrupt slope; the nutrition bags provide a good growing condition for growing the vegetation; and the grass and the shrub are grown in a mixing way to be capable of guaranteeing that the vegetation can take roots on the bare red sandstone abrupt slope, thereby recovering the vegetation in a large area and achieving the aim of soil and water conservation. The method has convenient construction, small investment, wide application and good effect, is hardly destroyed by water, can fast conserve the soil and the water, and performs ecological restoration.

Description

technical field [0001] The invention relates to a method for restoring vegetation on exposed red sandstone steep slopes, which is a method for effective water and soil conservation and ecological restoration aimed at the exposed red sandstone steep slope areas formed due to ecological damage. Background technique [0002] The Danjiangkou Reservoir area is one of the areas with the most severe soil erosion in Hubei Province. For a long time, due to the dual influence of natural factors and human factors, large-scale construction, unreasonable deforestation and land reclamation have seriously damaged forest vegetation, resulting in a large number of barren hills and slopes. Especially in the area north of the Han River, where there are large areas of exposed red sandstone steep slopes, the parent materials of soil formation are mainly Tertiary red sandstone and weathered limestone, which have weak resistance to rainfall impact and low erosion resistance .
