Zanesljivost ugotavljanja volumna dreves in lesne zaloge sestojev z enoparametrskimi funkcijami in stratifikacijo : doktorska disertacija = Reliability of tree volume and stands growing stock estimates using oneparametrical functions and stratification : doctoral dissertationKušar, GalZa ugotavljanje lesne zaloge sestojev v Sloveniji uporabljamo enovhodne volumenske funkcije - prilagojene enotne francoske (PEF) tarife. Namen disertacije je ugotoviti, kako zanesljive so enovhodne ... volumenske funkcije za ugotavljanje lesne zaloge sestojev, in raziskati možnosti njihove izboljšave sstratifikacijo. Na podlagi ocene pravega volumna dreves (vn), izraunanega s pomojo sekcijskih meritev (Newtonov obrazec), smo za drevesne vrste smreko, jelko in bukev izdelali regionalne trovhodne (prsni premer (d), višina drevesa(h) in premer na 7 metrih višine (d7)), dvovhodne (d in h) in lokalne enovhodne (d) volumenske funkcije (tarife) ter preverili njihovo zanesljivost.Na primeru vzornih ploskev v dveh GGE smo drevesom izmerili vhodne parametre d, h in d7 in s pomojo regionalnih trovhodnih volumenskih funkcij izraunali referenne volumne dreves (vr). Analizirali smo vpliv bonitete rastiša, razvojne faze, drevesne vrste in vpliv socialnega položaja na zanesljivost ocene volumna dreves. Iz referennih volumnov dreves smo izraunali regionalne dvovhodne volumenske funkcije (d in h). Z njimi smo izraunali volumne dreves (vrr) in za posamezne stratume (drevesna vrsta, razvojna faza, rastiše) izraunali lokalne tarife (d). Preverili smo zanesljivost treh metod uporabe tarif. Po sedaj izbranih PEF tarifah ocena povprenega volumna drevesa odstopa od referenne povpreno za -5,7 % (-16,7 do e vrsto in razred PEF tarif izberemo optimalno, na podlagi lokalne tar19,5 %).Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [G.
