摘　要：摘　要：低温环境分布最广，生物圈约80%以上的部分为常年低于5℃的低温地区，而在水环境(包括深海、极地海洋、海冰和高纬度湖泊等)中病毒的分布和含量是非常丰富的。在这些低温环境中，噬菌体在生态系统调控、全球生物地球化学循环(尤其是碳循环)、深海代谢和生物基因多样性保存等方面扮演着重要角色。该文主要对海洋和淡水湖泊中低温噬菌体的多样性进行简要综述。

Abstract: Abstract: Low temperature environments are widely distributed. Over 80% of biosphere is below 5℃ all through the year. Viruses are abundant in the aquatic biosphere， including in the cold environments of the deep sea， polar oceans， sea ice and high-latitude lakes. Phages play important ecological roles in overall regulating of ecosystem global biogeochemical cycles (especially carbon cycle)， deep-sea metabolism and a reservoir of the greatest genetic diversity on earth. Here， we briefly review the diversity of cold-active phages in marine and freshwater lakes.
