Abstract: Studying plant phenology is of great importance not only for precise assessment of regional carbon budget but also for improvement of regional climate models.Because it is unclear how plant phenology responds to environmental factors (especially the meteorological factors),it may be wrong for the recent conclusion that the vegetation growth season is linearly extrapolated with the advance of plant leafing and postpone of leaf yellowing in the context of increasing temperature.According to the cue of plant life history,control mechanisms of light,temperature and water on the key development stages of plants were summarized in this study.The primary factor affecting different development processes of plants was revealed.Control principles of light,temperature and water on plant phenology were compared between the studies in control experiment and model research.The importance of control experiment results of light,temperature and water to plant phenology in the construction of plant phenology models was explained.We also put forward that plant phenology should be explored according to the classification of main impact factors,the relationships between intrinsic parameters of plant phenology and cooperative co-evolution of the environment should be focused,and extent and function of mutual offset for the regulation of environmental factors in plant phenology should be explicated.
