요약: 본 연구는 소나무재선충병 선단지에서 잣나무를 용재로 활용하는데 있어 비용을 절감하기 위해 프로세서 기종별 박피작업의 생산성 및 비용을 분석하였다. 박피작업에 활용된 장비는 AFM 45, Woody 60 하베스터를 박피작업에 활용하였다. AFM 45의 박피작업의 생산성은 26.6㎥/PMH(Productivity Machine Hour), 박피작업 비용은 7,104원/㎥으로 산출되었다. Woody 60의 박피작업의 생산성은 18.4㎥/PMH, 박피작업 비용은 3,162원/㎥으로 산출되었다. 소나무재선충병 피해목을 대량훈증을 통해 목재로 재활용하는 비용(30,000원/㎥ 대비 비용 절감 효과가 있는 것으로 나타났다. 향후, 소나무재선충 피해목 박피에 따른 매개충의 우화 여부를 검증하여 자원화 방법을 제시하고자 한다.

Abstract: This study analyzed the productivity and cost of debarking operation by processor in order to reduce the cost of using the Pinus koraiensis as a timber in pine wit disease boundary area. The equipment used for the debarking operation was AFM 45 and Woody 60 harvesters. The productivity of the debarking operastion of AFM 45 was calculated as 26.6㎥/PMH (Productivity Machine Hour), and the cost was calculated as 7,104won/㎥. The productivity of the debarking operation of Woody 60 was calculated as 18.4㎥/PMH and the cost was calculated as 3,162 won/㎥. Although it was found that the cost reduction effect of recycling the Pinus koraiensis as a timber rather than mass fumigation method (30,000 won/m3) in boundary area, it is intended to suggest a method of recycling by verifying whether or not vector insects have emerged in the debarked trees.
