Problems solved by technology

Sand barriers are hard and inelastic. In case of strong winds and heavy rains, they are easily eroded by wind, washed and shifted, and lose the effect of windproof and sand-fixing.

Embodiment 1

[0010] A method for fixing sand dunes by using plant fibers to make sand barriers.

[0011] The first step: making sand barriers. The palm fiber is made into a fiber rope with a thickness of 2-4cm, and the fiber rope is knotted and woven into a mesh-like overall mechanical sand barrier. The mesh size is (20-50)cm×(30-50)cm.

[0012] Step 2: Fix the sand barrier. Cover the whole of the prepared sand barrier on the flowing sand dunes, and tie the edges to fixed wooden wedges.

[0013] The third step: natural plant growth. After the sand barrier is fixed, the dunes do not move, and natural plants such as sand rice, sand bamboo, and sand mustard invade and grow naturally. When the plant coverage rate reaches 40% to 50% and the distribution is even, the sand barrier can be withdrawn. Sand barriers can be used repeatedly.

Embodiment 2

[0015] The first step: making sand barriers, mixing wheat straw, straw and reeds to make fiber ropes with a thickness of 5 cm, and knotting the fiber ropes to form a mesh-like overall mechanical sand barrier. All the other are with embodiment 1.

Abstract

The sand-dune stabilization method includes the following steps: 1. making sand screen; making plant fibre into the fibre rope whose thickness is 1-5 cm, knot-tying and weaving to make the fibre ropeinto net sand screen, graticule specification is (10-60)cmX(20-60)cm, 2. fixing sand screen; covering moving dune with said invented said screen and tying the edge of sand screen to the fixed wood wedges uniformly distributed around dune; and 3. planting natural plants: after the dune is fixed, can not be moved, the natural plants of sand rice and sand bamboo, etc. can be naturally grown, when the plant covering rate is 40%-50% and the natural plants are uniformly distributed, the sand screen can be taken out and can be reused.

Description

(1) Technical field: [0001] The present invention relates to a method for combating desertification. (two) background technology: [0002] The first is to cover and fix the sand surface with asphalt and chemical emulsion. The second is to use straw, wheat straw, willow, stones, and soil to make band-shaped and grid-shaped scattered mechanical sand barriers. Sand barriers are hard and inelastic, so they are easily eroded by wind in case of strong winds and rainstorms, and will lose their windproof and sand-fixing effect due to being washed away and displaced. (3) Contents of the invention: [0003] The invention focuses on solving the above-mentioned problems, and utilizes plant fibers to make a reticular sand barrier, which has elasticity and has good windproof and sand-fixing effects. [0004] Technical scheme of the present invention is: [0005] The first step: making sand barriers. The plant fiber is made into a fiber rope with a thickness of 1-5cm, and the fiber r...
