Abstract: Studies on seed rain, seed pool, seed germinating process and seedling growth of Gordonia acuminata population show that its regeneration process can be divided into gap, transition, optimal and terminal phases. The population is characterized by a larger temporalspatial scale cycling regeneration during its regeneration process. Competition for light resource is one of the main forces of cycling regeneration, which is closely related with the ecological adaptive strategy of the population.
