Based on the forest management inventories in Lushihe Forest Bureau of Changbai Mountains in 2003 and 2013, and by using relative growth method, we analyzed the biomass and productivity of various forest types in Lushihe Forest Bureau. The results showed that the average of biomass was 175.07 t/hm2, and the natural forest biomass was higher than the plantations. Conifer species and the slow accumulation of broad tree species in natural forest have strong capabilities to yield biomass, while biomass of artificial Korean pine forest is the highest, which is on the red pine plantation. With the growth of different types of forest age of stand, biomass trend was different. With age increase of more than half of the growth forest types, biomass gradually increased; other forest types changed irregularly. Average productivity of all forest types in Lushihe Forest Bureau was 5.00 t/(hm2·a), and the natural forest biomass was lower than the plantations. The most productive plantation is artificial Korean pine forest, which is related to nursing, while the productivity of natural coniferous forest is the highest.
