Abstract

This study was designed to estimate gross primary productivity (GPP) in the Duke Forest at both ambient and elevated CO2 concentrations using a physiologically based canopy model. The model stratified the canopy of loblolly pine (Pinus taeda L.) forest into six layers and estimated photosynthesis in each layer according to the Faequhar submodel couples withthe Ball-Berry stomatal conductance submodel. Comparison between the modeled and ECM-estimated canopy C fluxes suggested that soil moisture, in addition to air vapor pressure, controlled canopy photosynthesis during the drought period.
