Soil fungi is an important part of ecosystem,fulfilling a range of important ecological functions. It contains beneficial fungi and pathogenic fungi,which together form the diversity of soil fungi. Soil fungal diversity and community structure is one important index in evaluating the ecosystem's health and stability. In recent years,research on soil fungi has not only done on soil fungal diversity and community structural characteristics but also on its biological functions such as biological control of plant pathogenic fungi and adsorption and degradation of harmful substances,and so on.This paper analyzed the factors influencing soil fungal diversity and predicted the possible future researches on the diversity of soil fungi,aiming to provide reference for future agricultural production,environmental protection and scientific research.
