Analysis of Interaction between Fungi and Environment Based on Lotka-Volterra Model

Abstract

The global carbon cycle is an important part of the earth's life activities, and fungi play a very important role as an important participant in the earth's carbon cycle. We used the Monod model combined with the Lotka-Volterra model to establish a model of the fungal degradation rate under the action of various fungi by studying the decomposition of the ground litter and wood fiber by fungi. We found that the degradation rate is very long when the ground litter and wood fiber are sufficient. After time, it will enter the dynamic balance and basically will not change. This is also an important reason for verifying that the earth carbon cycle can be stable for tens of thousands of years.
