Composite desertification control method for high-altitude gobi wind-blown sand region
The invention discloses a composite desertification control method for a high-altitude gobi wind-blown sand region. The method comprises the steps that strip-shaped gravel irregular trapezoid longitudinal dunes perpendicular to main disaster wind are constructed through gobi in-situ gravel, the dune height h ranges from 1 m to 2 m, the distance between the dunes ranges from 3h to 4h, and the dune length is not limited; windproof isosceles triangle sand pits are built between the dunes every 4-6 h, the pit height is 0.5h, and a plurality of gravel high-pit grid-like sand-protecting barriers which can prevent wind, block sand, collect rainwater and hold water are formed; and locally special salix bangongensis and myricaria elegans royle are planted in the sand-protecting barriers (three-year bare-rooted seedlings are mixed), and the planting space is 3*4 m. According to the method, measures are adjusted to meet local conditions, local materials are adopted, engineering measures are combined with biological measures, and the composite desertification control method which is suitable for high-altitude, high-cold and high-drought gobi wind-blown sand regions, high in adaptability, simple, feasible, economical, practical and high in operability is constructed.
