ABSTRACT

The decomposition of plant material and woody fibers is a key component in the carbon cycle. In the whole process, fungi are the key factor to decompose wood fiber. A recent research indicates that there is a certain relationship between fungi traits that determine the decomposition rate. Based on the results of the research, our team construct a mathematical model to simulate the decomposition of ground litter and woody fibers in the presence of a variety of fungi and explore the decomposition under the condition of interaction, different environment, change of environment and biodiversity.In this paper, we start by analyzing the experimental data in the reference of the MCM problem A and we use the cluster analysis method to divide the fungi in the data into two groups according to the growth rate, competitiveness and environmental tolerance. Then on the basis of topic requirements, we construct our decomposition model that the decomposition rate of fungi per millimeter is only related to the growth rate of fungi population and the moisture tolerance of fungi and this relationship is linear. We use our decomposition model to add up the decomposition effects of the two types of fungi. Our conclusion is that the decomposition rate of fungal community was the sum of the decomposition rates of each fungal population.
