Abstract
Obseg gozdne proizvodnje, opravljene s strojno sečnjo, se v Sloveniji povečuje. S tem so gozdna tla, kot neobnovljiv naravni vir, pogosteje izpostavljena poškodbam. Namen dela je bil zato ugotoviti vpliv vrste gozdne prometnice in prisotnosti sečnih ostankov na globino kolesnic, obseg kolesnic, globljih od 10 cm, ter dobljene rezultate primerjati z več različnimi merili sprejemljive poškodovanosti tal. Tako so bile leta 2018 na delovišču, s površino 2,56 ha in 1,382 m gozdnih prometnic (z izjemo gozdnih cest), opravljene meritve poškodb tal na 1062 odsekih. Povprečna širina gozdnih vlak je znašala 3,65 m, sečnih poti pa 3,73 m. Delež poškodovane površine je znašal 21,98 %, od tega 63,61 % zaradi sečnih poti. Na 36,19 % sečnih poti je globina kolesnic presegala globino 10 cm. Na sečnih poteh je bila povprečna globina kolesnic (8,64 cm) značilno manjša kot na gozdnih vlakah (18,93 cm). Globina kolesnic je značilno manjša ob prisotnosti sečnih ostankov na gozdni prometnici (6,36 cm). Od vseh izbranih meril sprejemljive poškodovanosti tal, so bile poškodbe tal na delovišču sprejemljive le po enem merilu, ki kot edino globine kolesnic ne upošteva med kazalniki poškodovanosti tal. Izsledki raziskave so pomembni predvsem z vidika preprečevanja poškodb tal pri gozdni proizvodnji, evalvacije različnih meril sprejemljive poškodovanosti tal in oblikovanja novih, strokovno sprejemljivih meril.

Title:Soil disturbances after fully mechanised harvesting in compartment of forest management unit Vrbovec
Abstract:
In Slovenia, timber volume harvested with modern CTL technologies, is increasing. As a result, forest soil, as non-renewable natural resource, is more often exposed to damage. The purpose of this thesis was therefore to establish the impact of the type of forest route and presence of slash on the rut depth, the extent of ruts exceeding 10 cm in depth, and to compare the results obtained with several various criteria of acceptable soil damage. In 2018, at the site measuring 2.56 ha and with 1,382 m of forest routes (except forest roads), soil damage measurements were carried out at 1062 segments. Average forest skid trail width was 3.65 m, and track width 3.73 m. Share of the damaged soil area amounted to 21.98%, of which 63.61% due to tracks. On 36.19% of tracks the depth of ruts exceeded 10 cm. Average rut depth (8.64 cm) on the tracks was significantly lower than on the skid trails (18.93 cm). Rut depth was significantly lower with the presence of slash on the forest route (6.36 cm). Of all of the criteria of acceptable soil damage selected, soil damage at the site was acceptable only under one criterion, namely the only one that does not consider rut depth as an indicator of soil damage. Results of the survey are particularly relevant from the point of view of soil damage prevention in forest production, evaluation of various criteria of acceptable soil damage, and creation of new, professionally acceptable criteria.
