Embodiment Construction

[0029] Below in conjunction with the accompanying drawings, the construction and use process of the lightweight pellet structure of the present invention will be further described:

[0030] Such as figure 1 As shown, a floating moisture preservation and heat preservation measure to promote the rapid recovery of vegetation in cold regions, it is composed of light ball 1 and gauze box 2, light ball 1 is made of PVC material, the particle size is 3 ~ 10mm ;The density is 3~25kg / m 3. The gauze box 2 is a net box made of glass fiber, which has the characteristics of corrosion resistance and ultraviolet resistance. The lightweight pellets 1 are piled up in the gauze box 2 with a thickness of 3cm to 10cm. The gauze box 2 is covered with a layer of gauze 3 to prevent the lightweight pellets 1 from being blown away by the wind.

[0031] In the on-site construction of vegetation restoration, for the area where the degraded alpine grassland needs to be restored, the surface soil of th...

Abstract

The invention discloses a floating type soil moisture and temperature preservation cold area vegetation quick recovery promoting measure. The measure adopts light balls and a gauze box, wherein the light balls are made of a polyvinyl chloride light material, and are piled in the gauze box with the thickness of between 3 and 10cm; and a gauze screen is covered on the gauze box. The light balls effectively prevent capillary action and evaporation of lower soil moisture so as to provide sufficient effective accumulated temperature and moisture conditions for vegetation sprouts in spring and summer, and ensure smooth growth and recovery of vegetation. Furthermore, along with the formation of recovered vegetation felty layer, lower permafrost environment can be maintained to be relative stablein a long term. Popularization and implementation of the measure have significant ecology and social and economical benefits in harmony and unity of engineering construction and ecological environmental construction, protection of biological diversity in a riverhead area, water and soil conservation, ecological balance maintenance and the like.

Description

technical field [0001] The invention relates to a novel light-weight thermal insulation and moisture conservation structure, which can be used for rapid recovery of damaged or degraded vegetation in permafrost areas, and can maintain the foundation of permafrost engineering and stabilize the temperature field at the bottom of the 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 herdsmen, but also has a significant ecological role and ecological value for protect...
