Abstract
V diplomski nalogi smo ocenili sestojno zgradbo v nižinskih gozdovih Dobrave, ki se nahaja v GGE Plešivec. Zgradbo gozdnih sestojev smo ocenjevali z metodo hitre ocene temeljnice. V 118 odsekih smo postavili stojišča na 100 metrski vzorčni mreži in na njih ocenili sestojno temeljnico s kotnoštevno metodo (k=2). Na podlagi zbranih podatkov smo ocenili sedanjo zgradbo gozdnih sestojev v Dobravi. Za gospodarska razreda gozdov na revnejših rastiščih smreke in jelke ter borovih gozdov na silikatu smo ugotovili razlike v vrstni in debelinski zgradbi. Ocenjena pestrost sestojne zgradbe in delež listavcev je bil večji v prvem gospodarskem razredu. Ravno tako tudi delež skupne lesne zaloge, ki je znašal 330 m3/ha. Pri primerjavi višinskih krivulj za smreko in rdeči bor nismo odkrili značilnih razlik v zadnjem desetletju.

Abstract:
In graduation thesis we have evaluated stand structure in lowland forest of Dobrava, which was situated in the forest management unit Plešivec. Stand structure and the basal area per hectare were estimated using angle count sampling and the relascope with a basal factor slope. In the 118 forest sections, a sampling grid was set up in the form of a systematic sampling net of 100x100 m. Based on data from the forest management plans and from our field sampling we estimated the development of forest stands. In the forest ofspruce and fir the stand structure was different from the stand structure ofspruce and pine forest. The estimation of mean growing stock in the spruce and fir forest was 330 m3/ha and the share of broadleaves was greater. The differencies in the height curves were not significant in the last decade.
