A stand structure control method to improve the carbon sequestration capacity of Pinus massoniana forest

Abstract

The invention discloses a stand structure regulation and control method for improving the carbon sequestration capability of a masson pine forest, and the method comprises the steps: (1), selecting a sample land, determining the name of trees planted on the sample land, measuring the breast diameter and height of a single tree on the sample land, and recording the coordinates of the position of the single tree through an adjacent grid method; (2), calculating the stand structure indexes of the sample land according to the name of trees, the breast diameter, the tree height and the position coordinate data: a crown overlapping index, a health degree index, a mingling index, a stand ratio, a uniform angle index and a diameter class distribution q value, and calculating a cutting decision index; (3), determining a stand structure regulation and control mode to regulate and control the stand structure according to the stand structure indexes and the investigation factors of the sample land. The method can promote the construction of a high-efficiency forest land production system through the regulation and control of the stand structure, and also can promote the construction of a benign-cycle ecosystem. After regulation and control, compared with the fixed carbon content of a reference forest stand, the fixed carbon content of a forest stand in a unit area is improved by 10%-25%, and the forest stand has the remarkable economic benefits and ecological benefits, and is very good in application prospect.

Description

technical field [0001] The invention relates to the field of forest management, in particular to a stand structure control method for improving the carbon sequestration capacity of masson pine forests. Background technique [0002] As the main body of terrestrial ecosystems, forests play an important role in maintaining global carbon balance and mitigating climate change. Masson pine (Pinusmassoniana Lamb) forest, as one of the main forest types in Zhejiang Province, has significant economic benefits. However, the stand structure of Pinus massoniana Lamb forest is simple, mostly single-layer pure forest, and its carbon sequestration function is low. Therefore, it is of great significance to explore scientific and effective forest structure control methods, improve its carbon sequestration capacity, and make the masson pine forest fully exert its ecological benefits under artificial management. [0003] According to different developmental stages and different cultivation pu...

Problems solved by technology

Based on the above studies related to harvesting and tending, most of them reveal the response of forests to different tending methods and tending intensities. Rarely, so far, there is no application for forest structure control methods that involve improving forest carbon sequestration capacity in the Chinese patent database
