다국어 초록 (Multilingual Abstract)

This study was carried out to examine the optimal road spacing and road density to minimize the total harvesting cost(road construction cost plus yarding cost) for mechanized yarding system to roadside by one - and two-stage two-way in Forestry build-up region. Chunchon-kun, Kangwon-do. The estimated road construction costs were ranged from ten million won to sixty million won per km. The results have indicated that cable crane was appropriate for yarding machine by one-stage, two-way, and estimated optimal road spacing was 1,698m-4,192m, averaged 3,087m, ;end road density was 3.44m/㏊-8.44m/㏊, and averaged 5. 12m/㏊. In hilly terrain, combination of medium yarder and Logging bogie was suited to yarding machine by two-stage, two-way, and calculated optimal road spacing was 1, 483m-3, 481m, averaged 2, 589m, and road density was 4.05m/㏊-9.46m/㏊, averaged 5.90m/㏊. In steep terrain, combination of medium yarder and jinsung winch was suited, and estimated optimal road spacing was 1,693m-3,982m, averaged 2, 960m, and road density was 3.68m/㏊-8.64m/㏊, averaged 5.38m/㏊.
