摘　　要：Both the stoichiometric characteristics and leaf functional traits can reflect the adaptability of plants to changes in the external living environment.In particular,for varying aged forest plants,the study of stoichiometric characteristics and leaf functional traits can reflect the plant’s life history strategy and its resource investment and allocation methods.In this paper,the 1.5-year-old,5-year-old,15-year-old and 20-year-old Castanopsis hystrix were selected as the research objects to investigate the trends of stoichiometry and leaf functional traits,and their synergistic changes were verified.The results showed that with the increase of age,the stability of C.hystrix stoichiometry gradually increased,and the functional traits also tended to invest in security.However,there was no synergistic change between the two,which might be attributed to the different sensitivity of the C.hystrix leaf to the environment at the life history level of 1.5-year-old to 20-year-old.
