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

[0026] 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.

[0027] 1. The cutting method of Quercus qinggang secondary forest was proposed, and the purpose and significance of the invention

[0028] 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 logging method for a secondary forest, in particular to a logging method for a Cyclobalanopsis glauca coniferous mixed forest based on a good site. The logging method comprises the steps of: (1) investigating a culled forest, determining that a forest stand has woods with diameters at breast height (DBH) of 24 cm or more and reaching a logging target DBH, and performing selective cutting operation, (2) counting woods with DBH of 5 cm or more in the forest stand to be logged, and calculating an average DBH; (3) marking the woods reaching the logging target DBH preliminarily; (4) counting a number of reserved trees and calculating an average DBH of the reserved trees; (5) and selecting a number of reasonably reserved trees after logging according to the average DBH of the reserved trees on the basis of a table shown in description; (6) adjusting the to-be-logged woods reaching the logging target DBH according to the step (3), so that the number of the reserved trees meets standards in the table, and logging the woods. The logging method is used for logging the Cyclobalanopsis glauca coniferous mixed forest in the good site, is simple and accurate in operation, and can reduce the waste of a large amount of forest resources.

Description

technical field [0001] The invention relates to a felling method of a secondary forest, in particular to a felling method of a mixed forest of Quercus qinggangensis based on a better site. 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 ...
