摘要

In recent years, the issue of climate change has attracted wide concerns. As the largest carbon pool in the global terrestrial ecosystem, the carbon sequestration function of forests and their products play an important role in mitigating climate change. Therefore, it is desirable to design a plan to significantly utilize and manage our forests. we built a GPD model to simulate the Growth‐Processing‐Deposition life circle of forests. The model divides the forest carbon sequestration process into three parts: vegetation growth, forest products carbon sequestration, and soil deposition. In the vegetation growth model, we considered various types of vegetation in the forest and quantified the biomass of vegetation through growth curves. At the same time, based on the correction amount, we quantified the carbon in vegetation regarding the biomass‐carbon sequestration conversion. In the processing model of woody forest products, we classified wood products into long‐term products and short‐term products, solved their carbon stocks separately, and calculated the corresponding carbon emission rates. In the soil deposition model, we stratify the soil in the vertical direction and calculate the carbon deposition in each layer separately. The GPD model outputs annual carbon sequestration and accordingly determines the optimal forest management plan in terms of carbon sequestration.
