Research on the Decomposition Rate of Fungi Combination Based on EIO Competitive Ranking and Sigmoid Model

Litterfall decomposition speed affect the development of carbon cycle rate of ecosystems and biodiversity. As the main decomposer, fungui understands the decomposition characteris- tics of fungui to litterfall, which is a key step in exploring the carbon cycle process. We established a fungal combinatorial decomposition model, which uses growth rate and temperature-affected humidity resistance as independent variables. Then according to the EIO competitive ranking, the sigmoid model is used to calculate the weight of each fungui. Bringing into the above decomposition model, a comprehensive model of decomposition rate under a variety of flora environment is finally obtained.
