英文摘要	Nitrous oxide (N(2)O) fluxes were measured in six littoral mirco-zones of Lake Huahu on Qinghai-Tibetan Plateau in the peak growing season of years of 2006 and 2007. The weighted mean N(2)O flux rate was 0.08 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1) (ranged from -0.07 to 0.35 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1)). The result was relatively high in the scope of N(2)O fluxes from boreal and temperate lakes. Emergent plant zones (Hippuris vulgaris and Glyceria maxima stands) recorded the highest N(2)O flux rate (0.11 +/- 0.24 and 0.08 +/- 0.17 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1), respectively). Non-vegetated lakeshore recorded the lowest N(2)O flux (0.03 +/- 0.11 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1)), lower than that from the floating mat zone of Carex muliensis (0.05 +/- 0.18 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1)), the floating-leaved plant zone of Polygonum amphibium (0.07 +/- 0.11 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1)), and the wet meadow (0.07 +/- 0.15 mg N m (-aEuro parts per thousand 2) h (-aEuro parts per thousand 1)). Standing water depths were important factors to explain such spatial variations in N(2)O fluxes. Significant temporal variations in N(2)O fluxes were also found. Such temporal variation in N(2)O flux in the littoral zone may be dependent on the interaction of water regime and thermal conditions, instead of the latter solely. These results showed the importance of the littoral zone of lake, especially the emergent plant zone, as a hotspot of N(2)O fluxes in such grazing meadows.
