Wood volume distribution as an indicatorof stand homogeneity

Abstract

The results of stand homogeneity definition are analyzed based on the percentage ratio of the distribution of tree number and the distribution of volume per diameter degrees. Homogeneity is defined based on homogeneity index (H) and Lorenz’s curve. Homogeneous stand is the hypothetical stand whose trees have equal volumes. Real stands, depending on their silvicultural form and treatment, as well as the development stage, are more or less distant from the absolutely homogenous state. The effect of the diameter degree width on the accuracy of homogeneity index calculation was determined and the possibility of applying the homogeneity index as an additional parameter for the assessment of site quality of selection stands was analyzed.
