Abstract

Helikoptersko spravilo je ponekod po svetu dokaj razširjeno, v Sloveniji pa tovrstnega spravila še ni bilo. V nalogi nas je zanimalo koliko je sploh primernih terenov za spravilo lesa z helikopterji, kakšne so izkušnje v tujini, prednosti in slabosti, organizacijske posebnosti in kakšni stroški pritem nastanejo. Največ lesa se spravi s helikopterji v Kanadi in ZDA, nekaj pa tudi v Evropi. Glavna prednost pred drugimi oblikami spravila je nepoškodovanost tal in sortimentov po opravljenem delu. Veliki stroški, ki pritem nastanejo pa so slabost, ki žal prevlada nad vsemi prednostmi. Območje,ki smo ga izbrali kot objekt raziskave je primerno za helikoptersko spravilo, vendar po opravljenem izračunu stroškov in prihodkov smo ugotovili, da so stroški helikopterske ure (če najamemo švicarsko izvajalsko podjetje) tako veliki, da je kakovostna struktura drevja na izbranem območju preslaba dabi pokrila stroške. Ob kombinaciji helikopter Slovenske vojske in švicarska ekipa na tleh pa dosežemo pozitiven rezultat. Izračun stroškov spravila so opravili v švicarskem podjetju HELOG. Koliko je potencialno primernih terenov za helikoptersko spravilo smo ugotovili s pomočjo GIS-a in sicer za preseke smo vzeli oddaljenost 1000m in več od javnih in gozdnih cest, naklon terena nad 50%, ter prekrili z masko gozdov. Skupno je potencialnih površin primernihza tovrstno spravilo v Sloveniji 20872 ha, od tega jih je kar 50% v GGO Tolmin.

Secondary title:	Organizational particularities in realization of helicopter logging
Secondary abstract:	Helicopter logging is used worldwide the most intensive in USA and Canada, butin Slovenia this kind of logging still has not been used. In thesis we tried to find out which areas are appropriate for this type of logging, what kind of experiences have been collected in foreign countries, what advantages and disadvantages have been identified, what kind of costs originates from helicopter logging and what are speciality in organizing such kind of work. The main advantage of helicopter logging is undamaged soil and logs. Heavy expenses are weakness, which predominate over all advantages. Area we chosen as research object is appropriate for helicopter logging, but we found out that the cost of helicopter hour is too high (if we rent company from Switzerland) and wood's quality is too poor to cover costs. If we make a combination of helicopter from the Slovenian Armed Forces and Swiss ground crew the calculation is positive. Calculation was done in Swiss company HELOG.We identified potentially appropriate areas for helicopter logging with GIS. For unopened areas we selected terrain which is more then 1000 meters away from public and forest road and slope is more then 50%. Slovenia has 20872 ha areas which are appropriate for helicopter logging, of which 50% are in GGO Tolmin.
