Abstract
Na dveh raziskovalnih hektarskih ploskvah na Pokljuki so v letih 2008 in 2009 izvedli polno izmero. Na podlagi premera dreves v prsni višini, premera drevesna 7 metrih ter višin so s pomočjo volumenskih funkcij - tarif, dvovhodnih deblovnic in trovhodnih volumenskih funkcij, izračunali lesno zalogo na ploskvah. Najnatančnejše so bile trovhodne volumnenske funkcije, katere upoštevajo vse tri parametre, najmanj pa tarife, pri katerih je bil volumen izračunan le na podlagi premerov dreves. Na raziskovalnih ploskvah so izračunali za 7 % oziroma 10 % višje vrednosti lesnih zalog, če so namesto trovhodnih volumenskih funkcij, uporabili eno-parametrske tarife.

Title:Volume functions of spruce research plots on Pokljuka plateau
Abstract:
In the years 2008 and 2009 a full measurement of two research plots, a hectareeach, was performed on the Pokljuka Plain. On the basis of the breast height diameters of trees, the diameters at 7 m tree height, and the full heights of trees, the growing stock of the two plots was calculated, using tariff functions - two parametric volume functions and three parametric volume functions. The most accurate were the three parametric volume functions that take into account all three measures, whereas the least accurate were thetariffs which use only the diameters of the trees to calculate the tree volume. On research plots, up to 7 % and 10 % higher values of growing stock were calculated when one parametric tariff functions were used instead of three parametric volume functions.
