英文摘要	Atmospheric nitrogen (N) deposition (N-dep), an important component of the global N cycle, has increased sharply in recent decades in China. Although there were already some studies on N-dep on a national scale, there were some gaps on themagnitude and the spatial patterns of N-dep. In this study, a national-scale N-dep pattern was constructed based on 139 published papers from 2003 to 2014 and the effects of precipitation (P), energy consumption (E) and N fertilizer use (F-N) on spatial patterns of N-dep were analyzed. The wet deposition flux of NH4+-N, NO3--N and total N-dep was 6.83, 5.35 and 12.18 kg ha(-1) a(-1), respectively. N-dep exhibited a decreasing gradient from southeast to northwest of China. Through accuracy assessment of the spatial N-dep distribution and comparisons with other studies, the spatial N-dep distribution by Lu and Tian and this study both gained high accuracy. A strong exponential function was found between P and N-dep, FN and N-dep and E and N-dep, and P and FN had higher contribution than E on the spatial variation of N-dep. Fossil fuel combustion was themain contributor for NO3--N (86.0%) and biomass burning contributed 5.4% on the deposition of NO3--N. The ion of NH4+ was mainly from agricultural activities (85.9%) and fossil fuel combustion (6.0%). Overall, N-dep in China might be considerably affected by the high emissions of NOx and NH3 from fossil fuel combustion and agricultural activities.
