Embodiment 1

[0059] Examples of Restoration of Provenance Available in Mild / Moderate Burned Areas

[0060] The implementation location of this embodiment is the Daxinganling Songling Forestry Bureau, and the implementation year is 2011.

[0061] (1) Investigation of burnt areas:

[0062] To determine the exact time a bushfire occurred:

[0063] By searching the forest fire files, it was determined that the exact time of the forest fire was June 2006;

[0064] Determining the level of damage to the burnt area:

[0065] 15% of the damaged standing trees belong to the slightly damaged fire-stricken land;

[0066] Determine pre-fire stand conditions:

[0067] Through searching historical archives and investigating the performance of larch remaining in the burned area, the forest before the fire was divided into mature forest, and the average diameter of the mother larch tree was 25cm, and a large number of larch trees had grown fruitful.

[0068] Judging whether the mother larch trees on th...

Embodiment 2

[0098] Restoration Examples of Provenance Unavailable in Mild / Moderate Burned Areas

[0099] The implementation location of this embodiment is the Daxinganling Songling Forestry Bureau, and the implementation year is 2011.

[0100] (1) Investigation of burnt areas:

[0101] To determine the exact time a bushfire occurred:

[0102] By searching the forest fire files, it was determined that the exact time of the forest fire was June 2006;

[0103] Determining the level of damage to the burnt area:

[0104] 15% of the damaged standing trees belong to the slightly damaged fire-stricken land;

[0105] Determine pre-fire stand conditions:

[0106] Through searching historical archives and investigating the performance of larch remaining in the burned area, the forest before the fire was divided into middle-aged forests, and the average diameter of the mother larch trees was 15cm, and a large number of larch trees had not yet become fruitful.

[0107] Judging whether the mother ...

Embodiment 3

[0135] Examples of Restoration of Severe and Very Severe Burned Areas

[0136] The implementation location of this embodiment is the Daxinganling Songling Forestry Bureau, and the implementation year is 2011.

[0137] (1) Investigation of burnt areas:

[0138] To determine the exact time a bushfire occurred:

[0139] By searching the forest fire files, it was determined that the exact time of the forest fire was June 2006;

[0140] Determining the level of damage to the burnt area:

[0141] 85% of the standing trees were damaged, which belonged to severely damaged fire-stricken areas.

[0142] Determine pre-fire stand conditions:

[0143]It is determined that the pre-fire forest is divided into middle-aged forests by searching historical archives and the larch left in the burned area. The average diameter of larch is 15cm, and a large number of larch have not yet become fruitful.

[0144] Judging whether the mother larch trees on the burned land can provide sufficient pro...

Abstract

The invention provides a post-fire recovery method for a cold temperate zone azalea 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 azalea Xing'an larch forests in various damage extents. According to the recovery method for the cold temperate zone azalea 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 and gradients 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 a rhododendron-Xing'an larch forest in a 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 also form a shallow root ...
