20.500.12556/DiRROS-7424 Analiza spremenjenosti količinske in vrstne sestave gozdov po dveh različnih metodah ter njuna primerjava Analysis of forest quantities and species composition alterations using two different methods with comparision Prispevek analizirana spremenjenost gozdnih sestojev po dveh metodah. S prvo ocenjujemo spremembe vrstne sestave rastlinskih skupnosti, druga metoda pa ugotavlja spremembe sestojev po vi{ini in vrsti lesnih zalog. Za izračun ocene spremenjenosti na ravni osnovnih enot popisa gozdov smo uporabili modelno optimalno in dejansko strukturo lesnih zalog po drevesnih vrstah v gozdnih združbah, popisanih v gozdnih odsekih. Zaradi podatkov, potrebnih za izračun, smo v analizo vključili le odseke, v katerih so ugotovili samo eno gozdno zdru`žo. Prikazujemo rezultate analize na ravni gozdnogospodarskih območij in gozdnih združb. Rezultate na višjih ravneh velikosti gozdnih površin smo dobili s tehtano aritmetično sredino rezultatov osnovnih izračunovn a ravni gozdnih odsekov. Rezultate ocen spremenjenosti smo prikazali tudi prostorsko in naredili primerjavo obeh metod. The article analyses composition alterations in forest stands using two methods. In the first, composition alterations in types of plant community areestimated and in the second, composition alterations in stands according toamounts and types of wood stock are established. To assess composition alterations at the level of basic units of forest inventory, the optimal and actual structure of wood stock was used in models according to tree types in forest communities within forest tracts. The data needed for calculations required analysis only of tracts containing one forest community. Results are shown at the level of forest management region and forest community. Results at higher levels of forest area were obtained using a weighted arithmetic meanof results from basic calculations at the level of forest tracts. The results of composition alteration assessment are also shown by area and comparisons were made of both methods used. gozdni sestoj zgradba gozda ocena spremenjenost sestojev vrstna spremenjenost kazalec spremenjenosti računalniški model true false true Slovenski jezik Angleški jezik Neznano 2017-07-12 09:14:25 2017-07-12 09:14:25 2022-08-12 13:45:53 0000-00-00 00:00:00 1999 0 0 str. 211-236 Vol. 60 1999 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630 0351-3114 URN:NBN:SI:doc-FB0JM755 605606 6206978 zbgl-60-7.pdf zbgl-60-7.pdf 1 619C0E8A59D50B9C97D651EEBBF9FEE8 a7a68526b43d71d71174ce75bc05a0caa803ff5a7d7f93ad62a21f358c196b52 0e549ab7-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/b52859ea-e3ea-44ef-9b50-6400cfe0db7f https://dirros.openscience.si/Dokument.php?lang=slv&id=9275 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
