Through the analysis and judgment of research result，according to the quantitative maturity of stand volume，the fitting value of volume of timber was selected as the tree mature age，and taking age grade（10 a as an age grade）into consideration，with the highest precision as judgment standard，the anticipant mature ages of commercial and public welfare P.tabuliformis forests were determined as 61 and 81 a，respectively.Over time，various interference activities against P.tabuliformis forest were reduced，so the forest could grow and propagate.The age groups of P.tabuliformis forest are shown in Table 4.
