Abstract

This study presents a method how to estimate the change of stand volume, the stand biomass and the carbon removals, using dynamic stand growth model according to whether the practices for forest management are implemented or not. As a result, it shows that the rate of stand change was significantly high if the practices were implemented. Consequently, the change of carbon removals was also high. The carbon removals at the stand where the practices were not implemented, was estimated about 0.27tC/ha. And the carbon removals at the stand where the practices were implemented, was estimated 166.02tC/ha(thinning from above) and 163.75tC/ha(thinning from below). It is confirmed that the thinning activities has a great influence on the change of carbon removals and there was little difference of the carbon removals between thinning types. From this result, it is proved that forest management like thinning activities is prerequisite condition to improve the carbon removals of stand.

본 연구에서는 동적생장모델을 이용하여 산림경영(간벌작업)의 수행여부에 따른 산림의 재적변화량, 산림의 바이오매스와 탄소흡수량을 추정하였다. 간벌 수행 여부에 따른 산림의 재적 변화량을 추정한 결과, 간벌을 수행하였을 경우의 산림 재적 변화량이 현저히 높게 추정되었으며, 이로 인한 산림의 탄소흡수량의 차이도 매우 크게 추정되었다. 간벌이 이루어지지 않은 산림에서의 탄소흡수량은 0.27tC(탄소톤)/ha로 추정되었으며, 간벌이 이루어진 산림에서는 166.02tC(탄소톤)/ha(상층간벌), 163.75tC(탄소톤)/ha(하층간벌)로 각각 추정되었다. 따라서 간벌은 산림의 탄소흡수량 증진에 매우 큰 영향을 미치는 것으로 판명되었으며, 각 간벌유형별 탄소흡수량은 큰 차이를 나타내지 않았다. 따라서 산림의 탄소흡수 및 탄소흡수량 증진을 위해서는 간벌작업을 통한 산림경영이 필수적인 요소라고 판단된다.
