Ocena stanja mreže šumskih puteva kao osnov za izradu programa otvaranja gazdinskih jedinica

Abstract

Planiranju mreže šumskih puteva prethodi detaljna analiza trenutnog kvalitativnog i kvantitativnog stanja šumskih puteva, a pre svega, utvrđivanje njihovog prostornog rasporeda. U radu je izvršena kategorizacija i ocena stanja postojećih puteva u GJ 'Željin' i 'Bukovik II' i definisanje delova gazdinskih jedinica sa nedovoljno rezvijenom mrežom šumskih puteva. Izdvajanje neotvorenih i nedovoljno otvorenih delova gazdinskih jedinica izvršeno je na osnovu gustine mreže šumskih puteva po odeljenjima i po mreži čije su ćelije dimenzija 500 x 500 m, a zatim i na osnovu omeđenih površina sa različitim širinama pojaseva oko šumskih puteva. Apsolutna gustina mreže šumskih puteva u GJ 'Željin' iznosi 18,62 m/ha, a u GJ 'Bukovik II' 12,03 m/ha. Postavljanjem omeđenih površina oko šumskih puteva, utvrđeno je da je u GJ 'Željin' preko 56% površine pokriveno pojasom širine od 0 do 200 m, dok u GJ 'Bukovik II' ovaj pojas pokriva 48% površine.

The planning of a forest road network is preceded by a detailed analysis of the current qualitative and quantitative state of forest roads, and above all, the determination of their spatial layout. This paper presents a categorization and assessment of the state of the existing roads in the FMUs 'Željin' and 'Bukovik II' and defining of the parts of management units with insufficiently developed networks of forest roads. The identification of unopened and insufficiently opened parts of management units was performed on the basis of density of a forest road network by departments and using a fishnet with 500 x 500 m cell dimensions and buffer zones of different widths around forest roads. The absolute density of a forest road network in the FMU 'Željin' is 18.62 m/ha and in the FMU 'Bukovik II' 12.03 m/ha. After placing buffer zones around forest roads, it was found that in the FMU 'Željin' over 56% of the area is covered by the zone ranging from 0 to 200 m, while in the FMU 'Bukovik II' this zone covers 48% of the area.
