Abstract: The plantations of Pinus koraiensis at the compartment 26 of Laoshan experimental station of Northeast Forestry University were studied. The plantations are 20 years old, and there are 3 240 individual plant per hectare. The results indicate the total storage of nutritive elements is 502.37kg·h-1·m-2. The mean storage is 25.12 kg·h-1·m-2 per annum. The storage of arbor is 81.46%, followed by shrub 11.17%, herb 2.56% and litter 4.81%, respectively. To improve the content and storage of nutritive elements and production, the management of plantations is needed.

Key words: plantation, Pinus koraiensis, mineral nutritive elements, arbor, litter
