Dynamic phenological models and their application in climate change research

Phyto-phenology is defined as the relationships between recurring vegetation cycle and environment. In the beginning, it mainly contributed to and adhered to agriculture, and in last century, several dozens of phenological models have been developed. These models could be classified into two groups, i.e., static model and dynamic model. The latter attempts to describe the physiological processes which preceded phenophase occurrence, and thus, could be used to somewhat accurately speculate the commencement dates of phenophases. In this paper, the dynamic phenological models including temperature model, chilling model and others were outlined, among which, temperature model is drawn more concentration than the other models. The underlying principles and hypotheses of the models were described, and several cases of their application in global change were demonstrated. The study of dynamic phenological models was just at its inspiring beginning, and there were more work to be done.
