Abstract: The thesis aims at offering theoretical foundation for the reasonable development and efficient management of subtropical native tree species. Based on a stem analysis of 64-year-old Cyclobalanopsis myrsinaefolia in the Jiaoximen Forest Region of Qingyuan，Zhejiang Province，China，growth （tree height, DBH, and tree volume）and climatic factors （annual rainfall and average annual temperature） were studied with a correlation analysis. Results showed that: （1） The total increment for tree height，DBH，and volume increased with age. （2）Also，curves for current annual increment of tree height and DBH had many peaks and could be divided into three stages. Demarcation points for tree height and DBH were separately the 16th and 33rd year， the 29th and 56th year. For tree height，the mean annual increment declined during the first 32 years and then rose slightly.（3）With tree volume，the mean and annual increment curves did not cross indicating that stem volume had not reached maturity.（4）Tree height was consistent with changes in annual rainfall and average annual temperature; however, there was no correlation between DBH increase and tree volume. Thus，we could conclude that the growth of tree height was more sensitive to the effect of outside factor；annual rainfall and average annual temperature were important environmental factors influencing increases in tree height，but not DBH and tree volume. Although the most 2 important factors were studied, it could not cover all the external and internal carses. So the correlation between growth and climatic factors needed to be made further studies.［Ch，4 fig. 2 tab. 18 ref.］
