土壤微生物生物量及多样性影响因素研究进展

Research Progress on Influencing Factors of Soil Microbial Biomass and Diversity

土壤微生物量碳、氮、磷是土壤微生物量的主要组成成分,其与土壤中各种营养物质的循环息息相关,土壤微生物生物量可作为环境变化的重要生命指标之一,而且土壤微生物群落结构更被认为是预警生态系统变化的敏感生物指标。该研究梳理概括了土壤理化性质、气候、立地植物和人为因素对土壤微生物生物量及其多样性的影响,并指出今后的研究热点是加强全球变化背景下大尺度多生态系统的整合,综合考虑多因素对土壤微生物的交互作用以及探讨在高生态压力下改善土壤微生物生物量及其多样性的方法,以期为今后土壤微生物多样性研究和实践提供参考依据。

Soil microbial biomass carbon, nitrogen and phosphorus are the main components of soil microorganism quantity, they are closely related with the cycle of various nutrients in soil, soil microbial biomass can be used as the environment change, which is one of the important indicators of life, and the soil microbial community structure is considered to be more sensitive biological indicator of warning ecosystem changes.The effects of soil physical and chemical properties, climate, site plants and human factors on soil microbial biomass and diversity were summarized, and the focus of future research is to strengthen the integration of large-scale multi-ecosystem under the background of global change were pointed out, in order to provide reference for future research and practice of soil microbial diversity, the interaction between multiple factors and soil microbial diversity was comprehensively considered and the methods to improve soil microbial biomass and diversity under high ecological pressure were discussed.
