摘要

1) Forest floor CO_2 fluxes measured by chambers at this second growth Douglas-fir stand are high and dominate ecosystem respiration. 2) The magnitude of CO_2 fluxes measured by EC are approximately 60% of those obtained from chamber measurements. 3) The closed, dense canopy of this particular stand and sloping terrain result in questionable eddy covariance measurements of fluxes and suggest the presence of significant horizontal and vertical advective fluxes.
