【 摘 要 】

In this paper, we present the results of studies on the relationship between the stand composition, the distribution row by the diameter classes of the stand and the wood density. Objects of study were coniferous forest stands with different participation of pine and spruce passed by thinning. Wood cores sampling was carried out on this stands and basic density of wood according to trees diameter classes determinate by maximum moisture method. The influence of the distribution curve of the trunks by the diameter classes on the wood density of pine and spruce is presented. Different trees quantitative representation of these species reflects on wood density and varies with the share of main species participation in the stand.
