Increases of nitrogen (N) deposition along with the climate warming could change the dynamics of soil carbon and nutrient,and alter the greenhouse gases (GHGs) fluxes.To examine how nitrogen deposition and warming affect GHGs fluxes (i.e.CO2,CH4,and N2O fluxes) in alpine grasslands,the treatments of nitrogen deposition with three ammonium nitrate (NH4NO3) levels (8,24,40 kg N ha-1 year-1),and the warming treatment using open top chamber (OTC),and the mixed treatment of warming and nitrogen deposition (8 kg N ha-1 year-1),were conducted in alpine meadow steppe (AMS),alpine steppe (AS),alpine cultivated grassland (CG) of the Qinghai-Tibetan Plateau(QTP).
