Fungus is one of the decomposers in biosphere. Through its unique decomposition effect, it decomposes, converts and absorbs the organic matters in animal and plant remains of the humus layer. Fugus plays an essential role in not merely maintaining the carbon cycle but ensuring the ecosystem on earth under the environment of geochemical cycle, which is beneficial to the stability of the Earth’s environment and the sustainable development of biodiversity. Our team simulated the decomposition of fungi by establishing a mathematical model, aiming to study the following questions: How do fungi with different traits interact and decompose the litter layer in a given land environment; What effect will moisture and temperature have on the decomposition process of fungi in different environments; environmental change trends and kinetic significance; fungal competition in a specific environment; taking into account the growth rate, the decomposition rate of fungi is estimated by the model . A variety of methods are used in the process of model establishment and data analysis: ‘single variable control’ experiment, Python software data analysis, Matlab software data analysis, system dynamics analysis and error analyzing and processing. Strictly control the simulation experiment conditions, guarantee the scientificity and rationality of the experimental data, eliminate interference factors, reduce gross errors, and improve the accuracy of experimental data.
