Abstract
With the rapid development of the petroleum industry, the total amount of carbon dioxide emissions continues to increase. Forests are the main way to absorb carbon dioxide, while the absorption efficiency of mature trees is gradually decreasing. This study established a queuing theory model, which is based on the analytic hierarchy process, determines the index weight of the factors and the gray correlation degree analysis method to establish a decision matrix. Through the decision matrix, the best way to use the forest can be obtained, and the forest resources can be used to the maximum extent, reduce carbon dioxide concentration and improve self-economy. Carbon sequestration models use forests and their derivatives to minimize carbon dioxide concentrations and increase the economic benefits of forests.
