ABSTRACT

As an important part of soil ecosystem, the existence and diversity of fungi directly or indirectly affect plant diversity and ecosystem functions. Researchers study the characteristics of different fungi. Focus on the growth rate and moisture resistance of fungi, the aim of this report is to build a growth and decomposition model of fungi to evaluate the influences of fungi on the environment, atmosphere, and ecosystems. We are expected to model the decomposition of woody fibers in a certain patch of land, and do so in the presence of various types of fungi breaking down woody fibers on the identical land. In this paper, Focused on the growth rate and moisture resistance of fungi. we used cellular automata to build fungus decomposition and growth model Using data from the given literature, we clustered 34 fungi and selected the most representative fungi among the three types. The birth, growth, hyphal density, temperature, moisture, and death of fungi are considered in the model. We established a death rule related to the age of fungi and a decomposition rule related to hyphal density. The competition rule is related to the competition ranking and the number of fungus. The randomness of competition is increased through the roulette algorithm We concluded that in the beginning, C4B fungus had a competitive advantage and occupied the most resources. Due to the competition of other species, the competitive advantage of C4B fungus is gradually (about 200 days later) replaced by C8H fungi.
