摘要
Through analysis on materials, the fitting empirical equation for growth process of Pinus tabuliformis was obtained, i.e. , the function with increment as variable and time as the independent variable. The mature age of P. tabuliformis was obtained by mathematical operation. The mature age of forest plantation was determined as 61 a, and that of public welfare forest was 81 a. And P. tabuliformis age groups were divided according to related technical requirements.
