20.500.12556/RUL-130937 Občutljivost tal na vožnjo z gozdarsko mehanizacijo in lastnosti sekundarnih gozdnih prometnic v gozdnogospodarski enoti Zaplana Susceptibility of forest soils to traffic with forest mechanization and the properties of logging trails in forest management unit Zaplana V diplomski nalogi smo v GE Zaplana ugotavljali občutljivost tal na vožnjo z gozdarsko mehanizacijo in lastnosti sekundarnih gozdnih prometnic, meritve so potekale na štirih objektih. Na negrajenih vlakah smo popisovali 62 profilov, na katerih smo merili pet parametrov: globino kolesnic, širino in naklon prometnice, kamnitost ter prisotnost korenin. Ugotovili smo, da je bila povprečna globina kolesnic največja na objektu Logatec (20,4 cm), sledil je objekt Smrečje (18,8 cm), nato Vrhnika (13 cm) in na koncu Podlipa (10,1 cm). Ugotovili smo značilen vpliv pojavov erozije na globino kolesnic in neznačilen vpliv prisotnosti korenin in kamnitosti na globino kolesnic. Naklon prometnice je značilno vplival na globino kolesnic, saj se s povečanjem naklona za 1 % globina kolesnice poveča za 0,374 cm. Model globine kolesnic pokaže, da je vključitev objekta v model značilna in nujna, saj se objekti med seboj močno razlikujejo. Globina kolesnice se tako najbolj poveča zaradi vpliva objekta (naklon od –12,02 do –4,16) ter naklona prometnice (0,241), ki sta visoko značilna, medtem ko kamnitost na globino kolesnice nima značilnega vpliva. We have determined the sensitivity of the soil to the driving of forestry machinery and the characteristics of skid trails. On unbuilt skid trails we have measured 62 profiles for five parameters: the depth of the ruts, the width and inclination of a skid trail, the amount of visible stone on the skid trail surface, and the presence of roots on the trail. We found that the average depth of the ruts was the highest in Logatec (20.4 cm), followed by Smrečje (18.8 cm), Vrhnika (13 cm) and Podlipa (10.1 cm). A significant impact of erosion onto the rut depth was established, while the presence of roots and stone had an insignificant effect onto the depth of the ruts. The inclination of the skid trail had a significant impact onto the depth of the ruts, as with the increase of inclination by 1% the depth of the ruts increases by 0.374 cm. The model of the rut depth shows that the integration of the object into the model is characteristic and necessary, as the objects differ greatly. The depth of the rut therefore increased the most due to the effect of the object (inclination –12,02 to –4,16) and the inclination of the skid trail (0.241), which are highly significant, while the presence of stone has no significant effect onto rut depth. pridobivanje lesa zbijanje tal naklon nosilnost tal wood production soil compaction slope soil bearing capacity true false false [I.
