Abstract
V diplomskem delu smo ocenili sestojno zgradbo v oddelku C03 na Podmeji gozdnogospodarske enote Trbovlje-Zagorje. V oddelku, ki obsega 290 m višinske razlike smo v smrekovih debeljakih postavili vzorčno mrežo gostote 100 * 50 m in na njej odmerili 5 arske ploskve. Na ploskvah smo popisali znake dreves terocenili sestojne gostote. Ocenjevali smo razlike v sestojni zgradbi na zgornjem in spodnjem delu pobočja (pod 650 m), na katerem leži oddelek. Razlike v sestojnih gostotah, vrstni in debelinski zgradbi ter razlike v višinskih krivuljah so vplivale na določitev tarifnih razredov. Lesna zaloga voddelku je znašala 514,9 m3/ha. Koeficient variacije za oceno temeljnice pa je bil na zgornji strani oddelka nižji (25 %) od koeficienta na spodnji stranioddelka (34 %).

Abstract:
In graduation thesis we have evaluated stand structure of forest section C03 in the forest management unit Trbovlje-Zagorje. A grid of circular sampling plots (500 m2) was set up in the form of a systematic sampling net of 100 * 50m. In the sampling plots we gathered data on trees and stand densities. In the forest section C03 the stand structure in forest at higher altitude was different from stand structure below 650 m. The differencies in the height curves were used to obtain the tariff functions (volume tables). The estimation of mean growing stock in the forest section was 514,9 m3/ha. The variability of the observed basal area in forest at higher altitude was lower (25 %) than in the strata of spruce stands at low altitude (34 %).
