The diurnal dynamics of CO2 gas exchange in the “peatland - atmosphere” system during the period of active plant vegetation absence

The paper studies the diurnal dynamics of CO2 fluxes in the surface layer at the meso-oligotrophic peatland in middle taiga using the eddy covariance technique. It was found that in cold season the daily balance of CO2 fluxes does not exceed g/m-2. NEE and Pgross values depend on PAR and Reco – on the temperatureof soil surface. Lower values of CO2 gas exchange in spring may be related toflooding much of the peatland after the snow melts.
