Analysis of the Cutting Strategy of Five Different Tree Species Targeting Carbon Sequestration

Abstract

Fully utilizing the carbon sequestration potential of forests will help to further mitigate the aggravation of the greenhouse effect. In this paper, five typical tree species in Xiaoxing’anling are used as research objects. Based on the differences in the carbon dioxide sequestration capacity of different tree species at different growth cycles, a mathematical model of annual carbon sequestration benefits is established, the optimal annual cutting rates of five tree species are calculated, and the carbon sequestration capacity after ten years and economic benefits of the forest are predicted. The results showed that proper cutting of mature trees can increase annual carbon sequestration by 32% compared to no cutting. In addition, by comparing different forest management strategies, it was found that reasonable harvesting can bring higher economic benefits. We also confirmed that the increase in environmental temperature is one of the factors leading to the decrease in forest carbon sequestration capacity. The results of this paper can provide a theoretical basis for optimal forest management strategies.
