摘要
土壤微生物生物量对环境因子的变化十分敏感,本文针对土壤微生物及影响因子,林火对土壤养分和土壤微生物生物量的影响等进行了综述,总结了国内外关于土壤微生物生物量的相关研究,同时评价了火干扰对土壤微生物生物量的影响,以及土壤养分元素变化与土壤微生物生物量的关系。研究结果对于进一步认识土壤微生物生物量的作用以及揭示干扰作用下土壤微生物生物量变化的机制研究具有重要意义。
The change of soil microbial biomass is very sensitive to environmental factors and the soil microorganisms and influence factors of forest fire are reviewed on soil nutrient and soil microbial biomass influence. The present study summarizes the relevant research on soil microbial biomass at home and abroad to evaluate the effects of fire disturbance on soil microbial biomass at the same time, and the relationship between soil nutrient change and soil microbial biomass. The results have important significance for further understanding of soil microbial biomass and revealing the mechanism of soil microbial biomass change under disturbance.
