摘 要 ：以黑龙江省东北林业大学老山人工林实验站26林班白浆土栽培的红松人工林为试验地，林龄20年，公顷株数为3240株，研究结果表明，矿质元素贮量为502.37 kg·h^-1·m^-2，平均每年为25.12 kg·h^-1·m^-2。其中乔木层占总量的81.46%，灌木层占11.17%，草本层占2.56%，凋落层占4.81%。为增加矿质元素含量与贮量，应调整林分结构，促进生长，提高林地生产力。

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.
