摘  要：
The principal felling age of poplar on Changjiang River beach was studied in Nangen forest farm of Huaining County of Anhui Province. Based on beach altitude, the beach was divided into two site conditions: the higher beach(15～16\^5?m) and lower beach(14～15?m). Model \%y=a+b\% ln\%A\% was selected as the growth model of poplar plantation. The yield table of poplar plantation was compiled by growth model. At the same time, the assortment yield table of poplar plantation was compiled based on the univariate volume ratio model. According to volume yield table and assortment yield table, the quantitative maturity age both two sites should be 7 years, technical maturity age of match blocks for higher beach and lower beach were 5 years and 6 years respectively. Economic maturity age was 10～13 years for higher beach(\%P\%=10%\,8%\,6%) and 11～12 years for lower beach (\%P\%=10%\,8%) on the basis of the maximum net present value. In conclusion, according to the three maturity age and management purposes the principal felling age of poplar plantation should be 10～14 years for higher beach and 8～12 years for lower beach.
