Primerjava stroškov in učinkov dveh tehnologij pridobivanja lesa v listnatih sestojih : diplomsko delo - univerzitetni študij = Compare the effects and costs of two different technologies of wood logging indeciduous conopies : graduation thesis - university studiesVranešič, UrošMeritve za diplomsko delo so potekale septembra in oktobra 2005 v gozdnogospodarski enoti Mirna gora. Namen naloge je bil primerjati učinke in stroške dveh tehnologij pridobivanja lesa v listnatih ... sestojih. V diplomskem delu so prikazane tudi študije časov. Oddelek so razdelili na štiri stratume, dva za strojno ter dva za klasično sečnjo. Drevju označenemu za posek, so za potrebe nadaljnje študije izmerili prsni premer, ocenili globino krošnje, debelino vej ter obliko debla. Ugotovitve kažejo, da je učinkovitost odvisna od morfoloških lastnosti. Sečnja dreves s strojem za sečnjo je učinkovitejša pri enoosnih drevesih, s kratko krošnjo ter tankimi vejami kot pa v sestojih sprevladujočimi drevesi z globoko krošnjo, večosnim deblom ter debelimi vejamiv krošnji. Povprečni učinek na delovno uro pri strojni sečnji znaša 6,78m3, strošek sečnje pa 15,23 EUR/m3. Povprečni učinek na produktivno uro pa znaša 9,42 m3. Pri klasičnem načinu sečnje pa je povprečni učinek 1,76 m3 na delovno uro, stroški sečnje pa znašajo povprečno 10,08 EUR. Cena spravila lesa z gozdarskim traktorjem na delovno uro znaša v povprečju 11,57 EUR/m3. Povprečnistroški izvoza lesa z zgibnim polprikoličarjem znašajo 6,44 EUR/m3 na delovno uro oziroma 5,01 EUR/m3 na produktivno uro.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [U.
