[Objective]Systematical study the research trends of atmospheric nitrogen deposition in last decade in China,in order to provide reference basis for relevant research.[Methods]The scientific metrology and information technology were used to visualize the patterns and trends of atmospheric nitrogen deposition in last decade in scientific literature by Citespace software.[Results]In the last decade,the effect of nitrogen deposition in forest ecosystem has been focused on the subjects of litter decomposition and soil microbial properties.Researches on the response of grass ecosystem to nitrogen deposition got increase significantly during 20052010.Regarding to the research of different ecosystems or sub-ecosystems,grass glade was not attracted as much attention as grassland.In addition,processes of carbon and nitrogen cycles were concentrated on the temperate zone and subtropical zone,and the research content becomes more abundant at present,and the methods are expected to promote the developments of big data analysis and modelling.In respect of the observation of nitrogen deposition flux,most studies referred to aquatic ecosystems.Moreover,nitrogen deposition flux with non-point source pollution got more attention due to the environmental degradation and the development of research methods.[Conclusion]The interdisciplinary and systematicness of atmosphere nitrogen deposition in China were getting enhanced gradually.And the research contents and scale were gradually getting associated and widened.Grass ecosystem,characteristic of microbial community and coupling relationship among nitrogen deposition,global climate change and human activities had attracted more attention in the last decade.
