The paper presents the pattern of long-term SO₄^2-, NH₄⁺ and NO₃^- bulk deposition along with the SO₂, NH₃ and NO_X emission in China from 2005 to 2018. The Generalized Additive models (GAMs) were constructed to predict the decadal bulk deposition of sulfate, ammonia and nitrogen, through the integration of satellite columns, PM_2.5 concentration, land-use information and meteorology variables. The R² values for established SO₄^2-, NH₄⁺, NO₃^- deposition models were 0.71, 0.62 and 0.53, respectively. The RMSE values ranging from 0.611 to 0.881, indicating the good predictive ability of three models. During 2005-2018, sulfur wet deposition decreased significantly in China due to the sharp reduction of SO₂emissions. In four regions such as Jingjingji region (JJJ), Yangtze River Delta (YRD), Sichuan Basin (SCB) and Pearl River Delta (PRD), SO₂ emissions decreased from 183.8, 107.6, 111.2, 55.2 kgS ha^-1 yr^-1 to 48.7, 21.8, 31.9, 23.0 kgS ha^-1 yr^-1 respectively, while SO₄^2- bulk deposition decreased from 16.54, 25.46, 24.35, 19.14 kgS ha^-1 yr^-1 to 10.16, 20.88, 15.20, 15.16 kgS ha^-1 yr^-1 respectively. Although emissions of NO_X have been effectively controlled in recent years, due to the slight increase in rainfall, there was no significant downward trend in bulk deposition of nitrate. The average bulk deposition of nitrate in the four regions were 8.21±0.50, 13.15±1.12, 10.02±0.28, 12.47±0.96 kgN ha^-1 yr^-1, respectively. It indicated that the intensity of NO_X emission reduction was not enough to offset the influence of rainfall change on the wet deposition of NO₃^-. There was a little variation in NH₃ emissions from 2008 to 2017, and NH₄⁺ deposition showed no trend, average values for the four regions were 12.07±0.77, 14.85±1.88, 10.02±0.88, 7.51±0.86 kgN ha^-1 yr^-1 respectively. In order to find the leading factors impacting deposition, the factors that influence bulk deposition were quantified. The most important factor affecting SO₄^2-, NH₄⁺ and NO₃^- wet deposition is rainfall, accounting for 20.1%, 20.4%, and 24.2% respectively, and then the precursor concentration, accounting for 19.47%, 18.32%, and 8.28% respectively.
