Analiza primernih območij za strojno sečnjo v gozdnogospodarskem območju Celje

Lesičar, Mitja (author), Krč, Janez (mentor)

Naloga obravnava primernost območja za strojno sečnjo v gozdnogospodarskem območju Celje. Vplivne dejavnike za primernost smo določili na osnovi študija virov in terenskega ogleda izvedbe del na konkretnem objektu. Tako smo se odločili za naslednje vplivne dejavnike: naklon terena, relief, nosilnost tal, delež iglavcev v lesni zalogi in prsni premer dreves. Z metodo AHP smo jim dodelili pomembnost (težo) in omejitvene vrednosti. Zatem smo z metodo večkriterialnega odločanja v programu Arcmap izdelali tematsko karto primernosti območij primernih za rabo strojne sečnje na ravni odsekov. Zaključili smo z validacijo modela. Ta je potekala s pomočjo revirnih gozdarjev, ki so za svoj revir ocenili ustreznost razvrščanja odsekov v razrede primernosti. Analiza je pokazala, da je zelo primernih za strojno sečnjo 12 % gozdne površine odsekov v GGO Celje. S strani revirnih gozdarjev je bilo preverjenih 5 revirjev. Skupno so ocenili 1491 odsekov (slabo tretjino vseh odsekov v GGO Celje). Za strojno sečnjo so 54,4 % odsekov ocenili kot zelo primerne in 26,2 % odsekov kot srednje primerne. Model se je izkazal za uspešnega in bo v pomoč pri načrtovanju na ZGS. V nadaljevanju takšnih raziskav bi bilo smiselno izdelati karto primernosti na ravni sestojev s prilagojenimi kriteriji.

• Title: Analysis of suitable areas for CTL technology in regional Forest Management Region Celje

Abstract

The purpose of the study was to analyze suitable areas for CTL technology in regional forest management region Celje. Limiting factors were determined based on other literature and field observation of cut-to length operation. We decided on the following limiting factors: slope of the terrain, surface shape, share of conifers in growing stock, bearing capacity of the soil and tree diameter. Using the AHP method we assigned those factors importance (weight) and limit values. Using the method of Multi-Criteria Evaluation (MCE) in the Arcmap program, we created a suitability map of areas suitable for the use of CTL at section level. The model was finished with validation that was carried out by the district foresters who assessed the suitability of the sections obtained on the suitability map for their district. We analyzed the suitability map which showed that 12% of the forest area of the sections in FMR Celje are very suitable for CTL. Five districts were validated by the district foresters. A total of 1491 sections were assessed (just under a third of the sections in FMR Celje). Out of very suitable for CTL sections 54,4% of sections were assesed as suitable for the CTL technology and out of medium suitable sections only 26,2%. The model has proven to be successful and will help planning at Slovenia forest service. In the future it would make sense to make a map of suitability at the level of forest stands with adjusted criterias.
