Measure for rapidly recovering vegetation in cold region

Abstract

The invention discloses a measure for rapidly recovering vegetation in a cold region. In the measure, open-cell heat insulation foam material and open-cell plastic thin film are adopted, wherein the open-cell plastic thin film can be arranged at the bottom of the open-cell heat insulation foam material or between two open-cell heat insulation foam material layers, the plastic thin film is provided with O-shaped, or triangular or polygonal holes which are in one-to-one correspondence with the holes of the heat insulation material, and bamboo nails or U-shaped steel nails are used for fixing the open-cell plastic thin film and the heat insulation foam material. By applying the measure disclosed by the invention, moisture capillary action can be effectively blocked, moisture evaporation rate can be greatly reduced, and sufficient effective accumulated temperature and moisture conditions can be provided for vegetation germination and growth in spring and summer, and the smooth growth and recovery of vegetation is guaranteedy, thus vegetation recovery is realized. Besides, since a vegetation recovery felty layer is formed, the covered permafrost environment can be maintained stable for a long time. By popularizing and implementing the measure disclosed by the invention, important ecological effect and social and economic benefits can be created for harmony and unity of engineering construction and ecological environment construction, protection of biological diversity in river source regions, water and soil conservation and maintenance of ecological balance.

Description

technical field [0001] The invention relates to a measure for rapid restoration of vegetation in cold regions, which can be used for rapid restoration of damaged or degraded vegetation in permafrost regions. This technology also has thermal insulation performance, which can play a role in maintaining the temperature field of the underlying permafrost to a certain extent, ensuring the stability of the permafrost engineering foundation. Background technique [0002] The Qinghai-Tibet Plateau is one of the areas most sensitive to global warming in the world, and it is also the area with the largest distribution of natural alpine grassland in my country. The animal husbandry is very developed, and the area of ​​natural alpine grassland reaches 1.28×10 8 hn 2 , and mainly distributed in permafrost regions. The alpine grassland ecosystem is not only an important means of production for developing regional animal husbandry and improving the living standards of local farmers and h...

Problems solved by technology

In view of the harsh natural conditions of the Qinghai-Tibet Plateau and the shortage of water and fertilizer in the surface soil, the first thing to solve is the problem of vegetation heat preservation and water retention in order to quickly restore vegetation. Therefore, the existing vegetation restoration technologies commonly used in conventional areas cannot adapt to the extreme cold of the plateau. , Moisture and temperature conditions required by alpine vegetation under arid conditions
