%X Freezing-thawing cycles often occurs in the regions of mid-high latitude and high altitude.This process can affect soil physical and biological properties,e.g.,soil water status,aggregate stability,and microbial biomass and community structure.Under its effects,the bio-indicators of soil microbes,i.e.,the kinds and quantities of some specific amino sugars varied,and the course and intensity of soil nitrogen transformation changed,which resulted in an increase of nitrous oxide(N2O)production and emission,and made the soil be a major source of N2O emission.This paper summarized the research progress on the aspects mentioned above,with the further research directions on the theoretical problems of soil N2O production and emission under effects of freezing-thawing suggested.
