Abstract

Pine wilt disease occurred for the first time in Busan in 1988 and the damage has since been increasing. In 2005, a special law was enacted for pine wilt disease by Korea Forest Service. Incidences relating to the forest pest had been frequent and chemical control as well as physical control techniques had been applied to control it. Therefore, there is a need to reduce the damage caused by the pine wilt disease through intensive management such as continuous monitoring, control, and monitoring based on active control as well as management measures. In this study, the UAV-based monitoring method was proposed as an economical way of monitoring the forest pest. The efficiency of the existing method and UAV method had been analyzed, and as a result the study suggested that UAV can be used for forest pest monitoring and indeed improve efficiency. The UAV-based forest pest monitoring method has a cost reduction of about 50% compared with the conventional method and will also help to reduce the area where the survey was omitted.

우리나라는 1988년 부산에서 처음 소나무 재선충병이 발생하였으며, 산림청은 국내 소나무림의 보호 및 산림자원의 확보를 위해 2005년에 소나무 재선충병에 대한 특별법을 제정하였다. 현재 소나무 재선충병의 발생 빈도는 증가추세를 보이고 있으며, 발생지역 확대를 막기 위해 화학적 통제 및 물리적 통제 기술이 적용되고 있다. 소나무 재선충병의 방제를 위해서는 먼저 피해 상황을 파악하고 주변 환경 및 특성을 고려한 최적의 방제 계획 수립이 필요하며, 넓은 지역에 대한 모니터링 방안으로 최근 UAV(Unmanned Aerial Vehicle)에 대한 관심이 증가하고 있다. 이에 본 연구에서는 UAV 기반 산림 모니터링 방법에 대한 경제성을 평가하고자 하였다. 기존 인력에 의한 모니터링 방법과 UAV를 적용한 방법의 효율성을 분석 한 결과, UAV 기반 산림 병해충 감시 방법은 기존 방법에 비해 약 50%의 비용 절감 효과가 있으며, 산림 조사의 누락 지역을 줄이는데도 도움이 될 것이며, 향후 추가적인 연구를 통해 UAV 기반의 산림 모니터링 방안의 검증이 이루어진다면 산림 조사 관련업무의 효율성이 크게 증가할 것이다.
