摘要:

从土壤微生物生物量、群落结构、活性3个方面综述火对森林土壤微生物群落的干扰作用,深入分析火对土壤微生物群落直接和间接的干扰机制,探讨影响扰动程度的关键火行为指标。提出今后研究中应该着重关注4个方面的问题:通过野外点烧试验,量化火行为指标与扰动程度的关系;通过长期监测,研究火对土壤微生物群落的长期干扰机制;地下火对土壤微生物群落干扰机制;土壤动物、金属氧化物等因素在干扰机制中的作用。

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
