Abstract: Biological nitrogen fixation is an important part of the entire planet's nitrogen cycle, and is the main source of initial productivity 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 environments 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.

Key words: extreme environment, nitrogen-fixing microorganism, research progress
