Problems solved by technology

[0005] At present, there is no scientific logging method for Quercus qinggang secondary forests in my country, and they are harvested based on experience, which is random, so the production efficiency is low, and a large amount of forest resources are wasted.

Embodiment Construction

[0025] Preferred embodiments of the present invention are provided below to help further understanding of the present invention, but the protection scope of the present invention is not limited to these examples.

[0026] 1. The cutting method of Quercus qinggang secondary forest was proposed, and the purpose and significance of the invention

[0027] Due to the large number of mixed tree species in the secondary forest, the size and height of the trees vary greatly; at the same time, the age structure is complex, and there are young forests, middle-aged forests, and near-mature and over-mature trees in the secondary forest stand, which cannot be the same as the artificial pure forest of the same age. , when the forest stand is mature, implement the clearcutting operation of the whole forest. And need to carry out selective felling, selective felling is to cut down a part of near-mature and over-mature forest trees. Generally, whether a tree is mature or not is determined by ...

Abstract

The invention relates to a secondary forest harvesting method, in particular to a medium-site-based cyclobalanopsis glauca broadleaved mixed forest cutting method. According to the scheme, the method comprises the following steps: (1) investigating a selectively cut standing forest to determine that the standing forest has trees of which the diameters at breast height are 18 cm or above and reach a cutting target diameter and can be cut; (2) making statistics about trees of which the diameters at breast height are 5 cm or above in the standing forest to be cut, and calculating an average diameter at breast height; (3) preliminarily marking the trees reaching the cutting target diameter; (4) making statistics about the number of reserved trees, and calculating the average diameter at breast height of the reserved trees; (5) selecting the reasonable number of the reserved trees after cutting according to the following table; (6) regulating the trees to be cut reaching the target diameter at breast height to make the number of the reserved trees consistent with standards in the table, and performing cutting. The method is applied to cutting of a medium site cyclobalanopsis glauca broadleaved mixed forest, and is easy to operate and accurate, and forest resource waste can be greatly reduced.

Description

technical field [0001] The invention relates to a felling method of a secondary forest, in particular to a felling method based on medium site Quercus qinggangbroad-leaved mixed forest. Background technique [0002] my country's Eighth Forest Resources Survey: The natural forest area is 122 million hectares, accounting for 64% of the forest land area, and the stock volume is 12.296 billion cubic meters, accounting for 83% of the forest stock volume. Natural forests are the main body of forest resources in my country; natural forests include primary forests and Secondary forest, secondary forest refers to the forest formed after the primary forest is disturbed by man or nature. At present, most of the natural forests in my country exist in the state of secondary forest. [0003] Among the main dominant species of natural arbor forests in the country, the area of ​​oak species is 16.1 million hectares, accounting for 13.70% of the area, and the volume is 1.281 billion cubic met...
