摘　　要：微生物对冰川前沿裸露地土壤的发育具有影响,并且参与生物地球化学循环,在后续生物的定居和生长过程中起着重要作用.近100多年来,全球气候持续变暖,平均温度升高了约0.74℃.在气候变暖的影响下,全球冰川快速退缩,研究冰川前沿裸露地微生物的原生演替成为当前热点研究领域.文章系统综述了冰川前沿裸露地微生物的群落结构和数量变化规律、微生物对土壤发育和改良的作用及N循环相关微生物群落结构的变化及其作用,旨在探索其演替规律,为确定微生物在冰川前沿这一特殊生境中的生态功能奠定理论基础.Microorganisms in the glacier foreland can promote the soil formation,participate in biogeochemical cycles and play an important role in the subsequent biological settlement and growth process.Over the past 100 years,the global average temperature has increased by 0.74 ℃.One consequence of this temperature increase is that glaciers have retreated in many mountainous areas all over the world.The studies of the primary succession of microflora in the glacier foreland have become the research focus in recent years.In this paper,the microbial community and quantity variation in the glacier foreland,the role of microbial in the soil formation are reviewed.The change and function of N cycle relating microbial in the glacier foreland primary succession are also reviewed.The aim is to understand the rule and function of microbial succession in the glacier foreland and to provide some theoretical basis to ascertain microbial ecological functions in this special ecosystem.
