Ecological reinforcement and vegetation restoration method and system for soil slope in cold and dry desertification area

Abstract

The invention relates to an ecological reinforcement and vegetation restoration method and system for a soil slope in a cold and dry desertification area. The method comprises the following steps of ecological degradable container preparation, ecological degradable container seedling raising, side slope intercepting and draining ditch arrangement, slope surface cleaning, three-dimensional degradable three-dimensional net hanging, side slope ecological degradable container reserved hole punching, reinforcing material preparation, reinforcing soil preparation, reinforcing soil spray seeding, grass seed spray seeding, ecological degradable container placement, reinforcing soil and vegetation maintenance. The method has the beneficial effects that an ecological reinforcement and vegetation restoration technology is beneficial to improving the stability of a soil body, and geological disaster problems such as peeling, erosion, slip collapse, inclined collapse and landslide of the side slope caused by factors such as rainfall or strong wind and sand are prevented; the influence of adverse climate environment on vegetation growth and development is reduced; the frequency and difficulty of vegetation maintenance management in the later period of the project are reduced; rich arbor, shrub and grass vegetation community layers can be quickly formed, and the greening effect and the landscape style are improved.

Description

Technical field [0001] The present invention belongs to the technical field of green devices, particularly, to a cold desertification in arid regions ecological soil slope reinforcement and vegetation repair method and system. Background technique [0002] Northeast my country, North China, Northwest and other regions, due to geographical location and natural climatic conditions, cold, distribution of drought, soil desertification area is wide, coupled with the serious ecological damage problems, leading to adverse natural ecological conditions, poor vegetation growth and its own ecological restoration condition . [0003] Cold and dry sandy areas soil slope ecological restoration project, the following major issues: First: geological stability is poor, affected by precipitation or strong wind and sand, prone to peeling off, erosion, collapse slip, oblique collapse, landslides and other geological disasters, the carrier directly affect vegetation growth and survival; second: in t...

AI Technical Summary

Problems solved by technology

[0003] In the ecological restoration project of soil slopes in cold and dry desertification areas, there are mainly the following problems: First, the geological stability is poor, and affected by precipitation or strong wind and sand, it is easy to peel off, erode, slide, collapse, landslide, etc. Geological disasters directly affect the carrier of vegetation growth and survival; second: under harsh natural and climatic conditions, it is difficult for vegetation to grow and develop, and because of the difficulty in watering and maintaining vegetation, it is easy to have stiff seedlings and dead plants. Seedlings and other problems, greatly reducing the survival rate of vegetation

In the existing technology, soil reinforcement technology and vegetation restoration technology are mostly divided into two systems for implementation, and there is a lack of ecological restoration research practice that combines the two organically, and there is a lack of geological ecological reinforcement and vegetation restoration of soil slopes in cold and dry desertification areas. integrated governance technology, so there is also a lack of corresponding facilities
