The seasonal fluxes of CO2 and its characteristics with relation to environmental variables were investigated under tropical lowland flooded rice paddies employing the open path eddy covariance technique. The seasonal net ecosystem carbon budget was quantified by empirical modelling approach. The integrated net ecosystem exchange (NEE), gross primary production (GPP) and ecosystem respiration (RE) in the flooded rice field was −448, 811 and 363 g C m−2 in wet season. Diurnal variations of mean… CONTINUE READING
