Embodiment Construction

[0029] Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

[0030] Such as figure 1 As shown, a measure to promote the rapid recovery of vegetation in cold regions, the surface of the damaged or degraded soil layer in the permafrost region is covered with a porous thermal insulation board 1, the thermal insulation board 1 is a PVC board, and its cross-sectional shape is inverted " U" shape. Hole 3 on the PVC plate is "O" type. There is dividing plate 2 around the PVC plate, and the height of dividing plate 2 is 1.5 times of the thickness of PVC plate.

[0031] In the on-site construction of vegetation restoration, for the areas where the degraded alpine grassland needs to be restored, the surface soil of the degraded area should be loosened, fertilized, and sowed before paving. Water can be properly sprayed under special drought conditions, and then the porous PVC plate 1 is laid on it, and there are dividing plat...

Abstract

The invention discloses a measure for promoting vegetation in cold regions to restore rapidly. The measure is characterized in that porous thermal insulation boards cover the surface of the destroyed or degraded soil layer in the frozen soil region; and baffles are arranged around the porous thermal insulation boards. By adopting the measure, the moisture of the lower soil mass can be effectivelyprevented from the capillary action and evaporation, the soil is ensured to maintain good moisture content in a longer time, sufficient effective accumulated temperature and moisture conditions are provided for germination and growth of the vegetation in spring and summer and smooth growth and restoration of the vegetation are ensured. Besides, along with formation of a restoring vegetation feltylayer, the lower permafrost environment can be ensured to keep relatively stable for a long term under the combined action of the restoring vegetation felty layer and the porous thermal insulation boards. Popularization and implementation of the measure have important ecological effects and social and economic benefits on harmony and unity of engineering construction and ecological environment construction, protection of biodiversity in the source regions of Yellow and Yangtze rivers, soil and water conservation, maintenance of ecological balance and the like.

Description

technical field [0001] The invention relates to a novel structure which can reduce the velocity of local air flow, increase the local air temperature and effectively reduce the evaporation rate of soil moisture, which can be used for rapid recovery of damaged or degraded vegetation in permafrost areas; The role of soil engineering slope and the temperature field at the bottom of the stable engineering foundation. Background technique [0002] The natural environment and ecological system of the Qinghai-Tibet Plateau are very unique, which play a fundamental role in guaranteeing the social and economic development of the plateau region, and also play an irreplaceable important role in the ecological and environmental security of China and even Asia. The rise in temperature has caused the permafrost on the Qinghai-Tibet Plateau to melt to varying degrees, which has had a serious impact on large-scale road and engineering construction, and has potential or direct damage to the ...
