摘　　要：青藏高原高寒草地是高寒生态系统物种及遗传基因最丰富和最集中的地区之一,也是全球生物多样性的热点和敏感区域。青藏高原的重要性也越来越被重视,针对其研究也在逐年增长,而土壤微生物作为影响生态系统功能十分重要的因素在青藏高原的重要性不言而喻。本文介绍了青藏高原草地土壤微生物的组成和类型,评价了土壤中微生物的功能类群、影响因子以及这些微生物对气候变暖、降水格局改变和氮沉降增加的响应,以期加深对青藏高原草地土壤微生物的认识。Alpine grassland on the Qinghai-Tibet Plateau is one of the regions with richest and most concentrated species and genetic genes in the alpine ecosystems,as well as a hot and sensitive area of global biodiversity.The Qinghai-Tibet Plateau has received more and more attention due to its importance,and relevant research is increasing year by year.Soil microorganisms are a crucial factor affecting ecosystem functions in the Qinghai-Tibet Plateau.In this review,we introduce the composition and types of soil microorganisms in grasslands on the Qinghai-Tibet Plateau,and assess the functional groups and influencing factors of soil microorganisms,and their responses to climate warming,alterations of precipitation regime and increased nitrogen deposition,aiming to deepen the understanding of grassland soil microorganisms on the Qinghai-Tibet Plateau.
