摘要 | The effects of nitrogen (N) addition and increased precipitation on nitrous oxide (N2O) emissions in alpine meadow ecosystems are still unclear. In this study, we measured N2O fluxes on the Tibetan plateau under interactions of moderate atmospheric N deposition and increased precipitation using a closed chamber method. Under all applied treatment conditions, the alpine meadow ecosystem acted as a source of N2O. The N2O emission rate reached a maximum of 74.83 +/- 14.40 mu g m(-2) h(-1), with a significant increase in emission rate of 68.76% following N addition when compared with the control plot (p<0.05). Increased precipitation, and its interactive combination with N deposition, enhanced the N2O emission rate by 53.90% and 44.52%, respectively. However, there was no significant difference between these two treatments. Increased precipitation would help to mitigate N2O fluxes under global nitrogen deposition conditions. |
