Abstract

Abstract: Under the background of global climate change, the study on nitrogen (N) cycling in grassland soil has become an urgent issue. Greenhouse gas N2O mainly comes from nitrification and denitrification processes in soil, which is driven by microbial functional groups. In order to clarify the microbial mechanism of N2O in soil, from the microbial functional groups of nitrification and denitrification in grassland ecosystems, we reviewed the quantities, composition and relative influencing mechanism and geography pattern of microbial functional groups of nitrification and denitrification in global grassland ecosystems, summarized the progress of N2O production, analyzed the future direction of microorganisms research in grasslands, and discussed future research on N2O production mechanism in grassland.
