英文摘要	An experiment was conducted to investigate the effect of precipitation and N deposition on N2O and CH4 fluxes and soil respiration (R-s) in the Gurbantunggut Desert from September 2014 to August 2015. The desert was a weak sink for CH4 (-0.92 kg C ha(-1) yr(-1)) and a small source of N2O (+0.13 kg N ha(-1) yr(-1)) and the annual rate of It, was 874 kg C ha(-1). Our work confirmed a relatively strong sink for CH4 in desert soils. Significant impacts on N2O, CH4 fluxes and R-s were found by increasing precipitation, with pulses of CH4 uptake and R-s accounting for 79.1% and 33.2% of annual CH4 uptake and R-s, respectively. N2O and CH4 fluxes were significantly enhanced by 7.8-109.6% by N addition, but it had no significant effect on R. Statistical significant interactions of precipitation and N addition on N2O and CH4 fluxes were found, and on Rs was lower than any single factor. Our results indicate that the Gurbantunggut Desert is a weak sink for CH4 and a small source of N2O, and is sensitive to elevated precipitation and N deposition.
