METHOD FOR DETERMINING total basal area GROWING

摘要

A method of determining the areas of the sections of the stand, comprising determining the sum of the areas of the cross sections of the visible parts of trees polnotometrom Bitterlich, characterized in that it further determines the amount of cross-section areas of interfering objects, using which the sum of the areas of the cross sections of invisible parts of trees, and the total sum of the areas of the stand sections are adding measured amounts basal area of ​​the visible part of the stand and the sum of the areas of the cross sections of invisible parts of trees, which is set depending on received based on ii regression equation: where: - the mean value of the total sum of the areas of the cross sections of the stand, obtained by measuring the aggregate, mna one hectare; a - constant factor reflecting the maximum possible, for the given conditions, the amount of cross-section areas in the absence of interfering objects; b - regression coefficient, which indicates the amount of the sums of areas of the cross sections of trees, closed interfering objects based on the object 1 mmeshayuschih; - average amount of interfering objects sectional area per hectare, meters, the measured value, then using coefficients itsient b, the total sum of the areas of the cross sections of the stand is determined by the formula: wherein: - the mean value of the total sum of the areas of the cross sections of the stand, - the mean value of sum of the areas of the cross sections visible (visually measured polnotomerom) part of the stand, mna 1 ha.
