본 연구는 강원도 춘천군에 위치한 임업진흥촉진지역(林業振興促進地域)을 대상으로 총수확비용(總收穫費用)(임도개설비(林道開設費)+집재비(集材費))을 최소화하는 양방향(兩方向)-단계집재(段階集材) 및 이단계집재(二段階集材)를 위한 적정임도간격(適正林道間隔) 및 임도밀도(林道密度)를 산출하였다. 이때의 임도개설비(林道開設費)는 km당 천만원부터 6천만원까지이다. 그 결과는 다음과 같다. 양방향(兩方向)-단계집재(段階集材)에서는 케이블 크fp인이 적합하며, 적정임도간격(適正林道間隔)은 1,698m~4,192m,평균 3,087m이며, 임도밀도(林道密度)는 3.44m/ha~8.44m/ha, 평균 5.12m/ha로 산출되었다. 양방향(兩方向)-이단계집재(二段階集材)에서 중지형(中地形)은 중형집재기와 로깅부기의 조합기종이 적합하며 임도간격(林道間隔) 1,483m~3,481m, 평균 2,589m로서, 임도밀도(林道密度)는 4.05m/ha~9.46m/ha, 평균 5.90m/ha로 산출되었다. 또한 급지형(急地形)은 중형집재기와 진성윈치의 조합기종이 적합하며, 임도간격(林道間隔) 1,693m~3,982m, 평균 2,960m로서, 임도밀도(林道密度)는 3.68m/ha~8.64m/ha 평균 5.38m/ha로 산출되었다.

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, and road density was 3.44m/ha~8.44m/ha, and averaged 5. 12m/ha. 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/ha~9.46m/ha, averaged 5.90m/ha. 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/ha~8.64m/ha, averaged 5.38m/ha.
