| description | The purpose of work was detection of regularities of bark formation on various parts of stems of Siberian larch Larix sibirica Ledeb. trees. In work, materials of ten trial areas established in larch stands of green moss group of forest types are used. 703 sample trees were cut down and measured. The trial areas were established at Priangarsky and Central Siberian subtaiga-forest-steppe forest vegetation regions. Sample trees were cut down into sections, equal to one tenth of the stem length. As a result of the carried-out works, the average sizes of double thickness of bark at stems of various diameter are established. The mathematical model, describing regularities of bark formation at various relative heights of stems of the Siberian larch trees with various diameters is constructed. This mathematical model is the basis for the auxiliary table containing data characterizing a bark share in diameter of a stem with bark. The relative sizes of bark on various sites of stems are established. For this purpose the double thickness of bark at height of the corresponding one-tenth height of a stem wood is taken for basic parameter. The bark sizes at other relative heights are expressed percentage of basic size. The relative sizes of bark changes from 206.8 % at the stem basis to 20.8 % for sections of the corresponding 0.9 shares of the stem height. The supplied generalizing information on the forest vegetation areas stated above is provided in work. The equation of pair dependence of relative double thickness of bark on the relative height of section of a stem is calculated. The obtained data might be used at creation of standards for valuation of the larch stands of the research area, such as volume, assortment and commodity tables. |
