Soshenskyi O. Peculiarities of biometrics structure, wood sort and merchantability structure of linden tree stands in the Lisostep of Ukraine

The dissertation deals with quantity and quality characteristics of volume stock of linden tree stands, peculiarities of their biometric structure and developing of corresponding standards for forestry. Statistical analysis of productivity of the linden stands was performed and forest estimation characteristics were observed. The verification of information of small-leaved linden was done, on the basis of which the necessity of developing of a number of forest estimation standards for the studied species was proved. The results of research of full-timber-factor, height-diameter ratio and size-quality structure of tree trunks and coma of linden trees were set out. Mathematical models of height, full-timber-factor, and size-quality structure were developed, on the basis of which height scale, volume and assortment tables were studied. The results of research of biometrics structure of linden tree stands according to the diameter were given. On the basis of beta-distribution mathematical model of distribution series of trees according to diameter and categories of technical competence was studied. The tables of merchantability structure of premature and mature linden tree stands were made.
