Stabilnost gozdnih površin v Sloveniji kot kriterij krajinske pestrosti in obstojnosti = The stability of forest areas in Slovenia as a criterion of landscape diversity and durabilityPirnat, Janez, 1960- ; Kobler, AndrejStabilnost notranjega okolja gozdov je pomemben kazalec biotske pestrosti na krajinskem nivoju, ko se odločamo o tem, ali bi določene gozdove lahko izkrčili. Zaradi tega smo se odločili, da ocenimo ... stabilnost notranjega gozdnega okolja v Sloveniji med letoma 1975 in 2012, saj so nam na voljo primerljivo dovolj natančni podatki o gozdni maski za teh 38 let. Štiri vrste sprememb pokrovnosti z gozdom (stabilni negozd, krčitve, zaraščanje in stabilni gozd) pojasnjujemo z empiričnim modelom v obliki odločitvenega drevesa, ki upošteva nadmorsko višino, naklon terena, talni tip, oddaljenost vsake celice na rastrski karti od gozdnega roba v izhodiščnem letu, oddaljenost vsake celice na rastrski karti od najbližjega naselja v izhodišč- nem letu. Pojasnjevalne modele smo zgradili po metodi strojnega učenja (Quinlan, 1986) z orodjem See5 (www.rulequest. com). Natančnost izbranega modela je znašala 74,65 %. V letu 2012 so stabilni gozdovi, katerih površina se od leta 1975 ni spreminjala, pokrivali 53 % Slovenije. Izmed vseh spremenljivk najbolje pojasnjujeta spremembo rabe začetna oddaljenost od gozdnega roba in deloma naklon terena. Oddaljenost od naselij in nadmorska višina nimata opaznega vpliva.Source: Acta Silvae et Ligni. - ISSN 2335-3112 ([Št.] 104, 2014, str. 35-42)Type of material - article, component partPublish date - 2014Language - slovenianCOBISS.SI-ID - 4040102
