Abstract

We developed a local-scale ecophysiological model, Sim-CYCLE Fine by modifying Sim-CYCLEwhich was developed for a global scale simulation. Sim-CYCLE Fine is able to simulate not only carbon fluxes but also plant growth with various time-steps from an hour to a month. The model outputs of CO2 flux and biomas/ LAI were highly reliable; we validated the model results with measurements from the eddy covariance technique and the harvest method (R2values of around 0.9 for both). The results suggested that the phenology and the seasonal dynamics of the C 3/C4 plant comunities affected significantly the carbon fluxes and the plant growth during the plant growing season.
