摘要：

极地冰芯的研究对于揭示过去环境的变化规律和预测未来气候环境具有重要意义 ,我国科学家在此领域取得了一系列丰硕成果 ,跨入了国际领先行列。冰芯微生物的研究在国外近年来才刚刚开始 ,并且日益受到重视。南北极和低纬度地区高山冰川深层冰芯中封藏着几千年甚至几十万年的微生物 ,对它们的研究将为微生物多样性研究、过去环境的变迁、生物基因的进化甚至生命起源的研究开辟新的途径

Abstract:

WT5BZ] Ice core of cold region glacier is a good medium for studying the change of climate and environment in the past. A large amount of microbial information was deposited in ice core and existed for several thousand even several hundreds of thousand years. The studies on microbes in deep ice will make a new way to understanding the diversity, evolution of microbes and change of environment. [WT5HZ]
