英文摘要	Nitrous oxide (N2O) emissions from the surface of the Three Gorges Reservoir (TGR), one of the largest dams worldwide, have not been well monitored before. This study measured N2O emissions from the surface of the TGR at seven sites from February to December 2009. The measurement found no significant spatial variation of N2O emission from the reservoir, but significant seasonal variation, with the contribution of N2O emission in warm season accounting for 86% of the total, and that in June significantly higher than the other times (P < 0.001). Furthermore, N2O fluxes were found to be significantly correlated with water surface temperature (T) and total nitrogen in water column (N) (F = 0.002 T + 0.017 N -0.035, R = 0.39, PT < 0.001, P-N < 0.01, n = 42). The overall annual N2O flux rate (mean + SD) was 0.014 +/- 0.021 mg N2O m(-2) h(-1), relatively low compared with those from other reservoirs. We also found low N2O emission rate from downstream immediately after the dam (0.010 +/- 0.009 mg N2O m(-2) h(-1)). Such a low N2O flux from TGR should be attributable to the low nitrogen (N) loading in the water body, which is the result of multiple approaches taken to maintain water quality and protect environment to decrease the input of N.
