Kompleksna presoja odvzema lesne biomase iz ekosistema v tehnološke namene : diplomsko delo - univerzitetni študij = Assesment of forest biomass extraction out of ecosystem for technological purposes : graduation thesis - university studies

Grbec, Samo

Diplomska naloga se osredotoča predvsem na ekološke vidike odvzema lesne biomase iz gozda in v tej luči primerja sortimentno in drevesno metodo sečnje na podlagi vsebnosti hranilnih elementov v ... različnih delih drevesa. Osnovna predpostavka je, da je iznos hranil pri sortimentni tudi metodi največji dopusten z vidika trajnostnega izkoriščanja gozdov. Zato je potrebno pri drevesni metodi sečnje višino poseka zmanjšati. To smo ugotavljali ločeno za iglavce in listavce ter po starostnih razredih, za listavce tudi pri zimski sečnji. Model je izdelan na podlagi pregleda literature. Dobljeni rezultati potrjujejo hipotezo, da z je drevesno metodo iz gozda iznešen bistveno večji delež hranil kot pri sortimentni metodi. Ugotovljena višina korigiranega poseka bi znašala pri listavcih 60 %, pri iglavcih pa 50 % v primerjavi z posekom pri sortimentni metodi. Proučevali smo tudi razliko med vsebnostjo hranilnih elementov v zelenih listih in v listni stelji. Iz tega smo določili višino poseka pri zimski sečnji listavcev z drevesno metodo. Poleg tega so v obzir vzeti tudi tehnološki in ekonomski vidiki obravnavane problematike.
