Abstract

This research was performed to evaluate the decay hazard for exterior above-ground wood in Korea. The Scheffer index (decay hazard index) was determined using the climate data of 72 different locations obtained from the website of Korea Meteorological Administration (KMA), and the wood decay hazard map was created. Jeju, Seogwipo, Gwangju, and Jeonju showing above 65 of Scheffer index values were considered to be high decay hazard zones. The rest showed the values in the range between 35 and 65, meaning the moderate decay hazard zones. However, the annual Scheffer indexes largely varied, which suggests that many moderate decay zones could turn into high decay regions with the climate change. Especially, considering that Korean weather tends to turn into the weather of subtropical region, the decay hazard of Korea seems to have high possibility to be gradually increased.

본 연구는 지상부 사용조건에서 야외에 노출된 목재의 부후위험을 평가하기 위하여 수행되었다. 국내 72개 장소에서 10년 동안 축적된 기후자료를 활용하여 Scheffer 지수가 계산되었으며, 이에 근거하여 목재부후위험지도가 작성되었다. 제주, 서귀포, 광주, 전주 지역의 Scheffer 지수가 65 이상으로 부후위험이 높은 지역에 속하는 것으로 나타났으며, 이 지역을 제외한 나머지 지역은 Scheffer 지수가 35에서 65 사이의 값을 보여 부후위험이 중간 정도인 것으로 판명되었다. 그러나 기후조건에 따른 Scheffer 지수의 편차가 크기 때문에 부후위험이 중간정도로 판단된 지역이 기후변화에 따라 부후위험이 높은 지역으로 변할 수 있는 가능성이 높은 것으로 보인다. 특히 최근의 국내 기후가 아열대성으로 변화하는 경향을 고려할 때 국내 부후위험은 점차적으로 증가할 것으로 판단된다.
