摘　　要：生物固氮是整个地球氮素循环中的重要环节,是极端环境初始生产力的主要来源,对全球生态系统的影响巨大,长期以来备受国际关注。本研究对近年来有关海洋(包括深海)、南北极地、高山、高原、冰川等极端环境固氮微生物及其作用研究进展进行了简要综述,同时就今后相关研究方向提出一些设想与展望。Biological nitrogen fixation is an important part of the entire planet’s nitrogen cycle,and is the main source of initial produc⁃tivity in the extreme environment.It has a great impact on the global ecosystem and has been a hot spot of international concern for a long time.This article briefly reviewed recent research progress on nitrogen-fixing microorganisms and their effects in extreme environ⁃ments such as oceans(including deep seas),north and south poles,mountains,plateaus,glaciers and so on,and some ideas and prospects for future research directions were put forward.
