Abstract:

Forest fire is one of the most important disturbance factors in forest ecosystem, and it has great impact on succession of forest soil microbial community. Understanding of the fire interference on forest soil microbial communities and the interference mechanism is very important to insight into the role and function of the fire interference on forest ecological variation, and to implement prescribed burning. This paper elaborates the role of the fire interference on forest soil microbial community from three aspects such as soil microbial biomass, soil microbial community structure, and soil microbial activities, analyzes in depth the mechanisms of direct and indirect interference of forest fire on forest soil microbial community, and discusses the key indexes of the fire behavior influencing the disturbing degree. In the final, four aspects in the future research work are proposed, i.e., quantifying the relationship between fire behavior indexes and disturbing degree by using outdoors fire experiments; investigating the long-term mechanism of the fire interference on forest soil microbial properties by the long time monitoring; studying the mechanism of the ground fire interference on forest soil microbial communities; and examining other factors, such as soil fauna and metallic oxide, which play roles in the interference mechanism.

Key words: fire, forest ecosystem, soil microbial communities, interference mechanism
