20.500.12556/DiRROS-14646 Priraščanje navadne smreke (Picea abies (L.) Karst.) in evropskega macesna (Larix decidua Mill.) na nekdanjih novinah v Koprivni v Karavankah Growth of Norway spruce (Picea abies (L.) Karst.) and European larch (Larix decidua Mill.) on former slash and burn farming areas in Koprivna in the Karavanke mountains Na podlagi meritev v obdobju 1962–2017 smo na raziskovalnih ploskvah na nekdanjih novinah v katastrski občini Koprivna izračunali debelinske, višinske in volumenske prirastke za najpomembnejši drevesni vrsti - smreko in macesen. Na raziskovalnih ploskvah, ki so bile prepuščene naravnemu razvoju, so srednjetemeljnični premeri manjši, število dreves pa večje od tistih v primerljivih gospodarskih gozdovih. V zadnjih tridesetih letih se je zaradi visokih sestojnih gostot zmanjšalo debelinsko priraščanje dreves smreke in macesna. Z dendrokronološko analizo smo ocenili vpliv klimatskih dejavnikov na priraščanje smreke in macesna. Na podlagi dendrokronološke analize smo ugotovili, da se leta z negativnim odzivom dreves v debelinskem prirastku od leta 1984 pojavljajo pogosteje. Based on previous measurements from 1962 to 2017 on forest research plots located on former slash-and-burn farming areas in the cadastral municipality of Koprivna, the diameter and height increment as well as volume increments of the two main tree species - spruce and larch - were calculated. These set-aside natural research plots have a smaller mean basal area diameter, but the number of trees is higher than in comparable managed forests. Due to the high-density of tree stands over the past thirty years, radial increment of spruce and larch has declined. To determine the influence of environmental factors on radial growth of spruce and larch, a dendrochronological analysis was conducted. According to the dendrochronological analysis of radial increment of trees, the number of years with a negative response has been higher since 1984. raziskovalne ploskve smreka macesen debelinski prirastek volumenski prirastek indeks gostote SDI dendrokronološka analiza research plots Norway spruce European larch diameter increment volume increment stand density index dendrochronological analysis true false true Slovenski jezik Angleški jezik Neznano 2021-12-02 14:06:26 2021-12-02 14:06:27 2022-08-20 03:36:50 0000-00-00 00:00:00 2021 0 0 str. 23-39 Vol. 126 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*56+630*26:630*17(497.4Koprivna)(045)=163.6 2335-3112 10.20315/ASetL.126.3 87554563 RAZ_Golob_Janez_i2021.pdf RAZ_Golob_Janez_i2021.pdf 1 9AC344BA59BA32042DF617F54BC77B10 652be411571a8acc3e1ff68c117ed8687dfade98d3af69acfd21e76d0e426544 c861eb78-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=18751 https://doi.org/10.20315/ASetL.126.3 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=18750 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
