The role of Eriophorum vaginatum in CH4 flux from an ombrotrophic peatland

摘要: Vegetation composition was found to be an important factor controlling CH4 emission from ombrotrophic peatland in the UK, with significantly greater (P 0.05) flux between plots E. vaginatum stems cut above water table and intact vegetation, yet there a 56% mean reduction efflux where were below < 0.05). The effect of on release mimicked by presence inert glass tubes. These findings suggest that main short-term role ecosystem is simply as conduit for release. longer-term importance fluxes through C substrate input suggested positive correlation night-time CO2 (r2 = 0.70), which only occurred when vegetation not senescent.
