Abstract:V raziskavi je bila predstavljena in preračunana ocena kakovosti stoječih dreves v sortimentno strukturo. Na 123 drevesih štirih drevesnih vrst je bila opravljena primerjava med dejansko sortimentacijo po poseku in računsko sortimentacijo na osnovi predhodno ocenjene kakovosti. Izmerili smo 869 gozdno-lesnih sortimentov ter primerjali rezultate računske in dejanske sortimentacije. Rezultati so pokazali dobro ujemanje pri smreki, nekoliko manj pa pri listavcih, kjer je bil večji vpliv notranjih napak na sortimentno sestavo. Metoda je praktično uporabna in daje uporabne rezultate za napoved sortimentne sestave. Izboljšati je treba še modele napovedi velikosti grč, s čimer bi natančnost napovedi še dodatno povečali.

Title:Converting stem quality assessments of standing trees into log grade structure
Abstract:A method for converting stem quality assessments into log grade structure was presented. For 123 trees of four species, a comparison was made between actual assortments after felling and virtual assortments based on pre-harvest quality estimates. A total of 869 actual assortments were measured, and the results were compared with virtual bucking and sorting into log grades. The results showed good agreement for spruce, while the accuracy for hardwoods was lower due to undetectable internal defects. The method proved useful for improving harvest planning and assessing forest stand quality. Further refinement of existing models (e.g., knot size) would increase the the accuracy and applicability of the approach under Slovenian conditions.
Keywords:assortment, quality assessment, standing trees, forest timber assortments, conifers, hardwoods, knots, virtual bucking, internal wood defects, volume structure
