ABSTRACT

Fungi, as decomposers, are critical in carbon cycle by decomposing woody fibers. In order to describe the dynamic process of decomposition of wood through fungal activities incorporating the interactions between different species of fungi, we abstracted a set of differential equations and established Fungal Decomposition Model based on the predator-prey relationship between fungi and wood and the competition relationship among fungi species. Then, for describing the short-term and long-term trends of the dynamics of interactions among fungi, we used MATLAB to simulate the decomposition progress and got a result that in the short term, different communities of fungi work together and the decomposition speed gets faster, while in the long term, the severe competition among fungi makes the more competitive colonies develop and the less competitive colonies go extinct.
