Method for restoring vegetation of subalpine meadow ecological system

The invention provides a method for restoring vegetation of a subalpine meadow ecological system, and belongs to the technical field of ecological engineering. According to the method, soil delamination is carried out on an undestroyed land parcel in a restoration area by utilizing a soil sampling tool, a soil layer in the range of 5-10 cm away from the delamination area is stripped, the surface layer of a destroyed area is covered with the soil layer and substances, such as residual roots and gravels, in the soil layer, the ground surface of the covered area is moisturized, and a seed bank left in the soil layer and an artificially supplemented seed source are used for accelerating soil structure and vegetation restoration of the destroyed area. In-situ restoration is carried out on the pre-stripped surface soil, proper micro-terrain improvement is also used, and the integrity of the land parcel where soil is sampled is restored. By means of the method, the damage caused by heterogeneity of restoration mater
