摘      要：Background： Capturing the response of forest ecosystems to inter-annual climate variability is a great *** this study, we tested the capability of an individual-based forest gap model to display carbon fluxes at yearly and daily time *** forest model was applied to a spruce forest to simulate the gross primary production（GPP）, respiration and net ecosystem exchange（NEE）.We analyzed how the variability in climate affected simulated carbon fluxes at the scale of the forest ***： Six years were simulated at a daily time scale and compared to the observed eddy covariance（EC） *** general, the seasonal cycle of the individual carbon fluxes was correctly described by the forest ***, the estimated GPP differed from the observed data on the days of extreme climatic *** new parameterizations were developed： one resulting from a numerical calibration, and the other resulting from a filtering *** suggest new parameter values and even a new function for the temperature limitation of ***： The forest model reproduced the observed carbon fluxes of a forest ecosystem quite *** the three parameterizations, the calibrated model version performed ***, the filtering approach showed that calibrated parameter values do not necessarily correctly display the individual functional *** concept of simulating forest dynamics at the individual base is a valuable tool for simulating the NEE, GPP and respiration of forest ecosystems.
