Light-response curves, in which the net photosynthetic rates change with photosynthetic photon flux densities (PPFD) setting at different levels, are usually used to describe the photosynthetic capacity of leaves. It is of vital important to build an appropriate mathematical model to simulate the parameters of light-response curves. The nonrectangular hyperbolic model was chosen for this study. The process of simulating the parameters in light-response curve mainly consisted of three steps: inputting data of photosynthesis rate at each PPFD level, inputting nonrectangular hyperbolic model formula and setting the initiative value of the parameters by using SPSS software. In this study, this method was used to build mathematical model of light-response curve for Quercus variabilis leaves. The simulated values well fitted to the measured ones.
