Abstract
Pri diplomski nalogi smo obravnavali spravilo lesa, ki je fizično zelo zahtevna in najdražja faza pridobivanja lesa. Pri spravilu lesa je zelo pomembno določanje najprimernejše oblike spravila lesa. S tem zmanjšamo stroške pridobivanja lesa ter težavnost dela. Za obliko spravila lesa je pomembno veliko vplivnih dejavnikov, ki so zbrani v gozdarskih računalniških zbirkah podatkov. Razvit je bil model napovedovanja oblik spravila lesa, ki naosnovi vhodnih podatkov določi optimalno obliko spravila lesa, za vsako rastrsko celico. Najpomembnejši del modela je metoda večkriterialnega ovrednotenja, ki določi stopnjo primernosti skupnega učinka vplivnih dejavnikov za posamezne oblike spravila lesa. Z modelom napovedovanja oblik spravila lesa smo izdelali modelno karto oblik spravila lesa za GE Bistra-Borovnica. Naredili smo primerjavo med modelno in terensko karto. Na osnovi analiz primerjav smo ugotovili in nakazali možnosti izboljšave modela napovedovanja oblik spravila lesa.

Abstract:
At graduation thesis we were dealing with wood skidding that is very hard to perform and is the most expensive phase in the process of wood production. Determining of wood skidding forms is the most important part of the process we mentioned before where we reduce the cost of wood production and at the same time difficulties of work as well. The form of wood skidding depends of many influential factors which are collected in forestry computer data bases. Krč has, in the year of 1995, developed a model of wood skidding prediction, which defines the optimal form of wood skidding for every raster cell, based of available data. The significant part of model is multicriteria evaluation method, which defines the adequacy level of the joint impact of influential factor for individual wood skidding forms. With prediction model we made a model of a map wood skidding types for GE Bistra - Borovnica. Furthermore we made comparison between model map and ground map. Based on analyses of comparison we established and showed the possibility of improvement of a modelof wood skidding prediction.
