METHOD OF DETERMINING DIMENSIONAL TECHNOLOGICAL PARAMETERS OF TREE TRUNKS Russian patent published in 2015 - IPC A01G23/00 

FIELD: agriculture.

SUBSTANCE: invention relates to technologies of forestry and logging industry. The method comprises measuring the length and diameters of the trunks in the bark along the length of the trunks and in butt sections. 100 trees non-doted in shape are taken, in which the length of the trunks is measured, as well as the diameters in the bark in the butt, the trunk diameters in the bark starting from the butt sections to the tops of the trees, and the trunk diameters at half the length of the trunk. According to the results of all measurements the relative lengths (h/H) and the relative diameters of the trunks in the bark corresponding to them are determined. On the aggregate of the data obtained the absolute dimensions of tree trunks are determined. Taking into account the coefficients on the bark and technological diameter of the trunk the variable diameters of the trunks without bark are determined at breast height, followed by determining the variable cross-sectional area of trunks without bark on the trunk length and the volume of tree trunks without bark.

EFFECT: technology enables to improve the accuracy of determining the technological dimensions of trees and timber volume.
