Abstract

The invention discloses a method for desertification control through salix bangongensis cuttage in a high-altitude gobi wind-blown sand region. The method includes the step that the groove cuttage salix bangongensis deep cuttage technology and the sand control and afforestation technology through salix bangongensis cuttage in the secondary desertification wind-blown sand region with the combination of protection of a surrounding gravel high-bank sandy barrier and recovery and protection of a platform biological living sandy barrier are formed by easily preparing sand in the secondary desertification wind-blown sand region. Measures are adjusted according to local conditions, local materials are used, engineering measures and biological measures are combined, and the method for desertification control through salix bangongensis cuttage in the high-altitude, high-coldness and high-drought gobi wind-blown sand region is easy to implement, economical, high in operability and beneficial to protection, expansion, utilization and popularization of endangered species.

Description

technical field

[0001] The invention relates to a method for controlling sand, in particular to a method for controlling sand by cutting Pangong willow in a high-altitude Gobi wind beach area. Background technique

[0002] Ngari area is located in the northern Tibetan Plateau, known as the roof of the world's roof, high altitude (average altitude up to 4500m above), high cold (annual average temperature 0 ℃), high drought (average annual rainfall of 50-100mm), thin air is The main natural features of this area are poor ecological environment and very scarce plant resources. Among them, Bangong willow (Salix bangongensis C. Wanget C. F. Fang) is one of the only two native tree species in this area. It has a wide distribution range and has long been adapted to the extremely dry Gobi desert environment. It is a unique and endangered species in Ngari area. Bangong willow is a small tree (big shrub) with many branches. It is a plant of the Salicaceae family Salix, generally 2-5 ...

Embodiment Construction

[0031] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0032] see Figure 1 to Figure 7 , a method for controlling sand by Pangong willow cuttings in the windy beach area of ​​the Gobi Gobi, comprising the following steps:

[0033] Step 1: In the high-altitude Gobi wind beach area, through site preparation, strip-shaped trenches 1 are evenly opened along the direction perpendicular to the main wind, and the topsoil is backfilled and leveled to form a trench cutting bed surface 2.

[0034] Step 2: Utilize the sand and gravel dug out of the trench to cultivate an isosceles trapezoidal ridge 3 on both sides of the trench 1, and set an isosceles triangular sand ridge perpendicular to the isosceles trapezoidal ridge 3 in the middle of two adjacent trenches 1. Ridge 4, forming gravel high ridge sand barrier 5;

[0035] Step 3: Flatten the windy sandy beach with high gravel ridges and sand barriers 5, open ...
