| 英文摘要 | This study aimed to understand the seasonal and spatial variations of N(2)O emissions from newly created littoral marshes in the drawdown area of the Three Gorges Reservoir (TGR), China. We measured N(2)O emissions at 10-day intervals during the growing season (early July to late September) in 2008. N(2)O emissions were measured with static chambers in four typical vegetation stands. The results showed great spatial variations of N(2)O emissions among the four stands. The greatest N(2)O emissions (0.052 +/- 0.063 mg N(2)O m(-2)h(-1)) were from Scirpus triqueter stand, while the lowest N(2)O emissions (0.020 +/- 0.020 mg N(2)O m(-2) h (1)) were from Typha angustifolia stand. To such spatial variations in N(2)O emissions, standing water depths and soil water content may be important explaining factors. Besides spatial variations, we also found significant temporal variations of N(2)O emissions in this area. The temporal variation of N(2)O emissions in the growing season was not found significantly related to any measured factor in the study. However, based on principal component analysis, we consider it partly caused by thermal conditions and the marked temporal variation of the standing water depth in the growing season, which to some degree influenced the process of denitrification and N(2)O emissions. These results about TGR enable us to make a more reasonable estimate of N(2)O emissions from large dam reservoirs, particularly those with a large drawdown area in the growing season in an agricultural landscape. |
