Vegetation restoration method for ecologically fragile areas in northern areas

Abstract

The invention discloses a vegetation restoration method for an ecologically fragile area in the north, and belongs to the field of vegetation restoration. A light-storing noctilucent material is filled between a circular truncated cone cylinder and a light-transmitting rubber film, and one-way perspective films are arranged on the inner wall of the circular truncated cone cylinder and the upper surface of the light-transmitting rubber film; the one-way perspective film is similar to a common mirror, the inner side cannot be seen from the outer side, but the outer side can be clearly seen from the inner side, so that the auxiliary repair device has a relatively strong light reflecting effect in the daytime, the warning effect on the repair subarea can be improved, the manmade accidental damage to the zoysia matrella in the repair subarea is reduced, and the repair efficiency is improved. On the contrary, the outer side cannot be seen from the inner side of the one-way perspective film at night, but the inner side can be clearly seen from the outer side, a certain illumination effect can be achieved at night, light can be absorbed by arranging a light storage type noctilucent material between the circular truncated cone cylinder and the light-transmitting rubber film, and the possibility of loss of stored light energy can be reduced by arranging the one-way perspective film.

Description

technical field [0001] The invention relates to the field of vegetation restoration, and more specifically relates to a vegetation restoration method in northern ecologically fragile areas. Background technique [0002] Grassland is an important material basis and ecological guarantee for human survival and development. Grassland degradation, as a complex land degradation process, is an important factor that leads to the deterioration of the natural environment, the imbalance of the ecosystem, and restricts the development of human society and economy. It is listed as the top ten environmental problems in the world today. Due to over-exploitation and other reasons, the area of ​​natural grassland in Liaoning Province has been continuously reduced, from more than 40 million mu in the 1980s to 15 million mu. Moreover, due to factors such as unreasonable use, 70% of the grassland has been desertified and degraded to varying degrees. The construction of artificial grassland in ...

AI Technical Summary

Problems solved by technology

The construction of artificial grassland in Liaoning Province is insufficient, the area is less than 300,000 mu, and there is a lack of dedicated varieties and efficient cultivation techniques

Over the years, many technical measures have been taken to vigorously restore and achieved great results, but the situation of grassland resources in Liaoning Province is also very grim

[0003] In view of the drought and water shortage in western Liaoning, some grassland plots have poor site conditions. In the past, the seedling emergence rate after directly supplementing grass seeds was relatively low, and the vegetation restoration effect was not ideal. When rainfall occurs, the soil particles on the surface of the soil layer will be affected by water runoff. loss of soil particles
