Određivanje Srednje Distance Privlačenja Primjenom Gis-a U Nizijsko-Brdskim Uslovima

Abstract: IzvodTransport sortimenata, prije svega oblog drveta, je najskuplji proces u proizvodnji. On se sastoji iz tri faze: primicanje, privlačenje i prevoz kamionima. Sa stanovišta troškova transporta najvažnije su prve dvije faze transporta. One u prvom redu zavise od udaljenosti mjesta sječe stabala od šumskog puta ili srednje transportne distance privlačenja i zato je određivanje njene vrijednosti veoma važno sa stanovišta planiranja otvorenosti šuma. Srednja transportna distanca je jedan od pokazatelja otvorenos… Show more

“…In contrast to other methods [28,29,32] and models [11,30,31] for the calculation of transportation distances, the geoprocessing tool TraDis provides several benefits. Specifically, an application of the TraDis tool (1) is more user-friendly because the interface (Figure 6) is intuitive, compact, and includes generally used environment and commands of ArcGIS Desktop extensions; (2) is more comprehensive because the workflow (Figure 1) covers all parts of primary wood transportation (i.e., pre-skidding, skidding) and both levels of dimension (i.e., 2D, 3D); ( 3) is more efficient because the third algorithm step (Figure 3) includes unique geospatial processes focused on reducing the calculation time and ensuring the correct topology of input/output data; and (4) is more accurate because the fourth algorithm step (Figure 4) uses only topologically correct data and the optional 3D data from the digital terrain model.…”

“…This approach was introduced to forestry around 2000 [26,27], and distances are calculated based on various geospatial methods and tools. Pentek et al [28] and Petkovic et al [29] proposed similar methods for the calculation of the PSD based on commonly available geospatial tools. These methods include four steps: (1) the center of gravity of each forest stand is defined, (2) the nearest point on the forest road to the center of gravity is defined and the connecting line between these two points is created, (3) the PSD is calculated based on the 2D or 3D length of the related connecting line for each forest stand, and (4) the PSD is corrected by the wood assortment skidding factor and the expected volume of cut timber.…”

“…Један од најважнијих фактора од којег зависе трошкови привлачења јесте транспортна дистанца привлачења на коју утичу: врста рељефног подручја, нагиб терена, присуство препрека на површини земљишта, усљед чега долази до заобилажења и продужења транспортне дистанце. Фактор продужења геометријске транспортне дистанце приликом рачунања стварне креће се од 1,1 до 2,6 у низијским, односно планинским условима рељефа (Lotfalian et al 2012;Petković et al 2015;Petković et al 2017a;Petković et al 2017б). Предуслов за анализу отворености јесте квалитетна и ажурирана дигитална база података коју је потребно водити у оквиру катастра примарних и секундарних шумских комуникација.…”
