This study has estimated the photosynthetic rate of an evergreen broad-leaved tree species, Cryptocarya chinensis, in Fu-Shan. Different canopy levels of C. chinensis show distinct efficiency of net photosynthetic rate. The saturation point of photosynthesis is estimated to be 782 μmol‧m^(-2)‧s^(-1). With 6.5 hrs of photosynthesis, leaves of C. chinensis were able to sequestrate and transport CO2 5.81 g‧m^(-2) and H2O 460 g‧m^(-2), respectively. The CO2 fixation efficiency of C. chinensis is lower than those of Ficus benjamina, Machilus kusanoi, and Michelia compressa, but is higher than that of Sassafras randaiense. The results provide valuable information for estimating carbon sequestrations of broad-leaved forests in Taiwan.
