Abstract: The results showed that in 12 to 31-year-old Pinus massoniana forests,the produc-tivity of 25-year-old forest in the highest,which is 9.07t/hm2.The nutrient content in leaves of 21-year-old forest is the largest,which indicated that the forest is of physio-logical exuberance.Ca accumulates mainly in the bark.The requirement of nutrient ele-ments to produce one ton dry biomass is 3.0763kg and 4.695kg for 12-and 21-year-old forest respectively.

Key words: Pinus massoniana, Natural forest, Nutrient elements
