Problems solved by technology

[0002] The soil slope soil in arid and semi-arid areas has the characteristics of lack of humus, loose soil and easy collapse, weak erosion resistance, sparse vegetation, low nutrient content, slow soil-forming process, and extremely poor soil fertility and water retention. The special physical and mechanical properties of the soil loess in the area and the strong seasonal changes in the climate in the arid and semi-arid areas lead to various disasters such as gullies and erosion on these slopes, causing serious soil erosion and destroying the ecological landscape. Extensive and growing year by year, how to effectively restore ecological vegetation and maintain long-term stability has been difficult to effectively solve

Embodiment Construction

[0018] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0019] A method for restoring the slope ecosystem in arid and semi-arid areas, comprising the following steps,

[0020] (1) Slope terrain arrangement and risk elimination, analyze the stability of the slope, if the stability is not good, take reinforcement measures for the slope, use the method of slope cutting and load reduction to reduce the height and slope of the slope, and press the slope at the top of the slope 1: 0.75-0.5 for slope cutting, using a combination of manual pneumatic picks and machinery for slope cleaning and leveling;

[0021] (2) For the construction treatment of hanging nets and anchor rods on the slope surface, lay the metal nets from top to bottom to the slope shoulders, and adopt the method of flat connection betw...

Abstract

The invention discloses a recovery method for ecological slope systems in drought and semi-drought regions. The method comprises the following steps of 1, finishing and danger removal of a slope topography; 2, construction treatment of slope surface hanging nets and anchor rods of a slope; 3, spray-seeding on a subbase course of a similar loam substrate; 4, spray-seeding on the surface of the similar loam substrate; 5, maintenance and management of the slope, wherein the step 5 comprises the sub-steps of covering the surface of the similar loam substrate with a non-woven fabric, strengtheningthe non-woven fabric, conducting watering, applying fertilizers, controlling diseases and pests, conducting reseeding and conducting later monitoring. According to the recovery method for the ecological slope systems in the drought and semi-drought regions, the soil structure is reasonable and stable, and stable vegetation on the slope of the ecological system can be quickly formed.

Description

technical field [0001] The invention relates to a method for restoring a slope ecosystem in an arid and semi-arid area, and belongs to the technical field of vegetation. Background technique [0002] The soil slope soil in arid and semi-arid areas has the characteristics of lack of humus, loose soil and easy collapse, weak erosion resistance, sparse vegetation, low nutrient content, slow soil-forming process, and extremely poor soil fertility and water retention. The special physical and mechanical properties of the soil loess in the area and the strong seasonal changes in the climate in the arid and semi-arid areas lead to various disasters such as gullies and erosion on these slopes, causing serious soil erosion and destroying the ecological landscape. Extensive and growing year by year, how to effectively restore ecological vegetation and maintain long-term stability has been difficult to effectively solve.
