Carbon cycle plays an important role in biogeochemical cycle, in which fungi play an extremely important role. Analyzing the changes of fungi in the process of decomposing lignin and cellulose in soil can help us understand the material cycle and energy flow, and also provide reference for the biological decomposition of waste straw and waste wood. First, we studied the rate at which fungi decompose cellulose and lignin. Based on the knowledge of power function and exponential function, combined with linear programming, we established the general model of fungal decomposition rate. The general model considers the effects of fungi growth rate, lignin content in the soil under initial conditions, temperature, humidity and other factors. By extracting the data from the relevant statistical graph, we get the corresponding function expression. Secondly, according to the statistical graph given in the competition, we extracted the data in the graph, and obtained the model of fungus decomposition rate and its growth rate. We also use the method of controlling variables to obtain the function analytical expressions of fungi growth rate and decomposition rate under different temperature conditions, and analyze the total model established under different weather conditions. Thirdly, according to the data given in the competition, we established the exponential function model of fungi moisture tolerance and decomposition rate by using the fitting method, and analyzed the error in establishing the model. Then, according to the current academic research results, we selected three specific strains and used the linear fitting method to get the function relationship of decomposition rate overtime. By comparing the corresponding linear function coefficients, we analyzed the interaction between different strains.
