[0036] Example
[0037] This embodiment relates to a method for promoting the restoration of severely degraded Pinus tabulaeformis forest land.
[0038] (1) Suitable area
[0039] It is used in areas suitable for the growth of Pinus tabulaeformis, and areas where the forest land has been seriously degraded into shrub land, shrub grassland, waste grassland or sparse woodland due to man-made destruction; and areas where enclosure measures are currently taken to restore forest vegetation.
[0040] (2) Artificial promotion measures for restoration of Pinus tabulaeformis forest land include:
[0041] a. Cultivate mother trees:
[0042] a1. Insufficiency in the non-Chinese pine parent tree or the Chinese pine parent tree (according to the parent tree distribution density formula n=S / [π(ɑh) 2 ]Calculation, the shrubland, shrubland, waste grassland or sparse woodland that is less than the calculated result shall be planted and arranged in the shape of "products" so that the parent tree row is pe...
