Wood is vulnerable to wood-attacking fungi during its production and application,resulting in a decline in physical and mechanical performance,which is one of the limiting factors to the outdoor application of wood products.In recent years,wood decay mechanism has been widely explored to provide a solid theoretical basis for developing wood preservation technology.This paper briefly reviews the research on wood decay mechanism as below:1)Changes in structure,composition and properties of wood during the decay process;2)Theory of enzymatic degra...
