Problems solved by technology

However, in arid and semi-arid areas, rainfall is low, evaporation is large, and soil water shortage is serious. In barren hillside areas, dense planting is used for afforestation, and the survival rate of trees is low, which is likely to cause waste of seedlings and decline in ecological and environmental benefits.

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0025] The invention adopts the method of combining natural slope surface, horizontal ditches, ditches and ridges miniature rain collection technology, and covering water and moisture conservation technology. figure 1 It is a flow chart of vegetation recovery on barren hills and slopes in arid and semi-arid areas in the specific embodiment of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0026] Step 101: In the arid and semi-arid barren hillside area, build horizontal ditches along the contour lines.

[0027] If the slope of the arid and semi-arid barren hillside area is less than 25 degrees, the slope length between two horizontal ditches shall be 3 meters; if the slope of the arid and semi-arid barren hillside area is greater than 25 degrees, the s...

Abstract

The invention discloses a method for restoring vegetation on barren mountains and sloping fields in arid and semi-arid regions. The method comprises the following steps of: building a horizontal ditch in an arid and semi-arid barren mountain / sloping field region along a contour line; building semi-arc-shaped water collecting ridges in the horizontal ditch in an earth furrow spacing way, wherein a ditch is formed in the two water collecting ridges and is taken as a seedling planting region; and planting arid and semi-arid region greening trees in a seedling planting region and covering a covering layer. The technical scheme of the invention is suitable for arid and semi-arid regions, and has the advantages of easiness for operating, low cost, high wood survival rate, quick vegetation growth and good water and soil holding effect.

Description

technical field [0001] The invention relates to the technical field of vegetation restoration, in particular to a method for restoring vegetation on barren hills and slopes in arid and semi-arid areas. Background technique [0002] Water is the limiting factor for the growth and distribution of vegetation. In arid and semi-arid regions, due to the lack of water, the natural vegetation presents a discontinuous patchy distribution. [0003] In my country's arid and semi-arid barren hillside areas, human activities are intense, natural vegetation is severely damaged, vegetation coverage is very low, soil erosion is serious, and the ecological environment is very fragile. It is a long-term strategy to improve the natural appearance of barren hills and slopes in this area and to prevent and control soil erosion by vigorously carrying out planting trees and grasses, greening barren hills, and restoring vegetation. However, in arid and semi-arid areas, rainfall is low, evaporation...
