METHOD OF EVALUATION VOLUME STOCK round wood at logging sites BY CATEGORY fineness and located in a tree trunk

摘要

A method of estimating the volume of stock on a round timber felling categories size and location in the trunk of the tree, characterized in that the separate elements of the forest is carried out measuring the diameters of all the trunks designated for felling trees on the cutting area in a height of 1.3 m in the cortex and the distribution of these trees steps thickness range and felling trees with credential measurement of the dimensions of height and diameter of the trunks in the bark and bark from the butt to the barrel tops, obtaining heights depending on the diameters of trunk at a height of 1.3 m in the cortex and Calculations volumes to mid-stage thickness multiplied by the number of trees in the thickness of the step and the steps of summing and thereby receive their values ​​for wood member; then the obtained evaluation amounts of the different categories taking into account the round timber on timber elements are summed and thereby receive their values ​​at the cutting area, characterized in that the selection is carried out only accounts trees from the central thickness stages, where height is measured on the diameter at a part of growing trees in 1.3 m logs of diameter difference in the crust and double-crust thickness, as measured by any gentle way a 4-fold replication, wherein the diameter measurement felled tree bark is carried on the stump and the site of application notches, and in failing to make measurements at these locations, make measurements within adjacent notches with the measurement height mismatch; then calculating the average of a plurality of credentials felled trees growing and diameter ratio without bark and bark at an altitude in the region of 1.3 m, and the diameter ratio is also calculated for the felled tree bark and bark on you
