Embodiment 1

[0071] Examples of Restoration of Provenance Available in Mild / Moderate Burned Areas

[0072] The implementation location of this embodiment is the Songling Forestry Bureau, and the implementation year is 2011.

[0073] (1) Investigation of burnt areas:

[0074] To determine the exact time a bushfire occurred:

[0075] By searching the forest fire files, it was determined that the exact time of the forest fire was June 2006;

[0076] Determining the level of damage to the burnt area:

[0077] 18% of the damaged standing trees belong to the slightly damaged fire-stricken land;

[0078] Determine pre-fire stand conditions:

[0079] Through the search of historical archives and the investigation of larch remaining in the burned area, it was found that the forest before the fire was divided into mature forests, and the average diameter of the mother tree of larch was 22cm, and a large number of fruit had begun;

[0080] Judging whether the mother larch trees on the burned lan...

Embodiment 2

[0109] Examples of recovery by manual seeding where provenance cannot be provided in light / moderately burned areas

[0110] The implementation location of this embodiment is the Songling Forestry Bureau, and the implementation year is 2011.

Abstract

The invention provides a post-fire recovery method for a cold temperate zone ledum Xing'an larch forest burned area, and aims to put forward a detailed and systematic post-fire recovery method specific to burned areas of the ledum Xing'an larch forests in various damage extents. According to the recovery method for the cold temperate zone ledum Xing'an larch forest burned area in various conditions, through a burned area survey, the exact time of the forest fire, the damaged level of the burned area, the forest stand forest stand before the fire, the condition that whether larch seed trees in the burned area can provide sufficient provenances for area renewal or not, the site condition survey of the burned area and renewed plant investigation of the burned area can be determined, through the judge of seed year, different damage levels can be determined, and whether larch can provide sufficient provenances for area renewal or not can be determined, so that a technical support for large area burned area ecological restoration engineering construction is provided.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a post-fire restoration method for the fire-burnt forest of Duxiang Xing'an and larch forests in the cold temperate zone. Background technique [0002] The cold temperate coniferous forest in Northeast China is the southernmost part of the Eurasian coniferous forest region across the northern part of Eurasia, and belongs to the southward extension of the southern bright coniferous forest in East and West Besia. This area is one of the main timber forest bases in my country, with a forest vegetation coverage rate of over 70%. Xing'an larch is the dominant tree species in this area. [0003] Xing'an larch has a wide range of adaptation, and can grow into forests in relatively dry and barren gravel mountains and wet swamps. Its root system has strong plasticity. It can not only form a well-developed root system on deep and fertile soil, grow into a tall forest, but ...
