英文摘要	Terrestrial bryophytes substantially regulate ecosystem processes in high latitude and high elevation ecosystems; however, the role of these plants in mediating soil emissions of non-CO(2)greenhouse gases (GHGs) (N2O and CH4) in these ecosystems remains poorly understood. A removal experiment was conducted to investigate the influence of bryophytes on soil non-CO(2)GHGs emission in a subalpine coniferous forest on the eastern edge of the Tibetan Plateau. Bryophyte removal decreased the average N2O emission rate, but did not significantly alter the CH(4)flux rate. The cumulative amount of N2O emission and CH(4)uptake was decreased by bryophyte removal. Compared to bryophyte-removal plots, soil in the control plots had higher concentrations of soil organic C (SOC), total N (TN), dissolved organic C (DOC), dissolved N (DN), and exchangeable NH4+. The control plots also had higher cumulative N2O emission and CH(4)uptake compared to plots with bryophytes removed. Bryophyte-removal significantly changed the relationship between soil non-CO(2)GHGs flux rates and soil water content, induced a linear decreasing relationship between the N2O emission rate and soil water content and a quadratic relationship between CH(4)flux rate and soil water content in the bryophyte-removal plots. Results from this study indicate that bryophytes may regulate non-GHG emissions from subalpine coniferous soils and demonstrate that in the presence of bryophytes, these soils may act as a greater N2O source and CH(4)sink in southwestern China.
