摘　　要：随着人类活动引起的一系列全球变化,如气候变暖的加剧,这可能会增加森林采伐和火烧干扰的频率和严重性,对土壤微生物及其驱动的生物地球化学循环产生不确定的后果。本文结合以往研究中采伐和火烧干扰对土壤理化性质,微生物群落结构,微生物生物量的影响的研究进展进行综述,充分探讨了微生物对采伐和火烧干扰的响应,进一步理解土壤微生物对陆地生态系统养分循环的调节作用,以期为后续关于森林土壤微生物动态的相关研究提供支持。With a series of global changes caused by human activities, such as the intensification of climate warming, this may increase the frequency and severity of forest logging and fire disturbances, and produce uncertain consequences for soil microorganisms and the biogeochemical cycles driven by them. This article summarizes the research progress of the effects of logging and fire disturbance on soil physical and chemical properties, microbial community structure, and microbial biomass in previous studies, fully discusses the response of microorganisms to logging and fire disturbance, to further understand the regulation of soil microbes on the nutrient cycle of terrestrial ecosystems, in order to provide support for subsequent studies on the dynamics of forest soil microbes.
