Restoring method of original vegetation site of high-altitude meadow area

Abstract

The invention discloses a restoring method of an original vegetation site of a high-altitude meadow area. The method specifically includes the following steps of firstly, stripping off turf, wherein the original turf is stripped off, and original bushes are transplanted; secondly, storing the turf, wherein a highland turf storage area is arranged, and the turf stripped off in the first step is stacked in a concentrated mode, covered with a dense-mesh net and pressed by a heavy object; thirdly, spraying water on the turf for conservation, wherein water is sprayed on the turf stacked in the concentrated mode in the second step for conservation; fourthly, processing the original site, wherein the original ground is flattened, and large-grained stone is removed; fifthly, restoring the site, wherein the original site processed in the fourth step is directly covered with the turf conserved in the third step. By means of the process, the effect of environment-friendly restoration constructionunder a highland special environment is improved, the construction difficulty and construction cost are greatly reduced, the damage of engineering construction to a local ecological environment is reduced to the minimum, and the method has quite beneficial technological advantages.

Description

technical field [0001] The invention relates to the technical field of vegetation restoration, and more specifically relates to a restoration method for the original vegetation site in a high-altitude meadow area. Background technique [0002] The meadow area at a higher altitude belongs to the typical plateau temperate zone semi-arid monsoon climate, dry and cold, with thin air and large temperature difference between day and night. The local soil is dominated by alpine soil, with strong bones, low soil nutrient content, and high sand and gravel content, which is very easy to desertify and is very unfavorable for vegetation development. At this stage, the common site cleaning and restoration methods in China are to remove all surface covering soil and surface vegetation in the early stage, and cover greening soil and spray grass seeds in the later stage. However, the construction is difficult and costly, and the environmental adaptability of planting vegetation is very high...

AI Technical Summary

Problems solved by technology

The local soil is mainly alpine soil, with strong bones, low soil nutrient content and high sand and gravel content, which is very easy to desertification, which is very unfavorable for vegetation development

At this stage, the common site cleaning and restoration methods in China are to remove all surface covering soil and surface vegetation in the early stage, and cover greening soil and spray grass seeds in the later stage. However, the construction is difficult and costly, and the environmental adaptability of planting vegetation is very high. Poor, low survival rate

In addition, even if a small number of projects adopt the technology of turf covering when the site is restored and constructed, the turf is also artificially cultivated turf, and the construction cost is very high
