Rapid sand fixation treatment method for moving dune

Abstract

In order to quickly control the mobility of the moving dune caused by wind erosion, on the basis of establishing a physical sand barrier, fast-growing sand-fixing plants are selected, and a moving dune treatment method capable of quickly forming a sand-fixing effect is established. The physical sand barrier adopts straw checks made of straw, the straw checks gridding physical sand barrier is established on the surface of the moving dune, the specification of the straw checks is 1m * 1m, and the ground surface height of the straw checks is reserved to be 20-30cm. Mangosteen rock astragalus membranaceus which grows rapidly is selected as a main planting species, the planting spacing is 1m * 1m, and a field planting point is a central point of every grass square grid; according to the method, a herbaceous sand-fixing plant artemisia desertorum (artemisia desertorum is planted in a broadcast sowing manner, and the sowing rate is 750-1000g / mu) which grows quickly is selected as a configuration species. After the species combination sand stabilization mode is implemented, the vegetation coverage of 40% or above can be rapidly formed within 1-2 years, the fixing of the moving dune can be rapidly realized, the movement of the dune can be effectively controlled, and the method is a quick-acting moving dune rapid treatment technology.

Description

technical field [0001] The invention belongs to the technical field of sand prevention and control, and relates to a method for fast-fixing mobile sand dunes by selecting a combination of fast-growing sand-fixing shrubs and herbs on the basis of establishing a physical sand barrier. The demand for rapid treatment of surrounding mobile sand dunes such as sand-crossing roads, railways, and power transmission lines. Background technique [0002] my country's sandstorm hazard control has made great achievements, and is at the forefront of the world's sandstorm hazard prevention and control. In theory, it basically reveals the cause, type and degree of sandstorm damage. In practice, a variety of engineering measures and biological measures for the prevention and control of sandstorm hazards have been explored, a sand control strategy based on solidification and combination of solid resistance and resistance has been formulated, and a series of sandstorm hazard control models ada...

Problems solved by technology

However, with the continuous development of my country's economy and living standards, new requirements have been put forward for sand dune control projects. For example, under certain specific conditions, it is necessary to quickly control mobile sand dunes and achieve comprehensive control of mobile sand dunes in a short period of time. However, the current wind-blown sand control technology still adopts the traditional sand-fixation technology system, and lacks targeted technical measures for rapid control of mobile sand dunes, especially for the rapid control of mobile sand dunes along railways, highways, and power lines. A governance technology that can quickly and effectively control the movement of mobile sand dunes
