Abstract

The objective of this research was to provide basic information of Thuja orientalis stand for prediction system, which consists of the best model of diameter and basal area. Data was from cores of 45 sample trees of Thuja orientalis stand that was designated as a natural monument (No. 62) in Yeongcheon, Chungbuk. Of the projection functions tested, polymorphic equation using the overlapping data showed higher precision of the fitting than anamorphic equation using. In diameter growth, Schumacher polymorphic equation of $D_2={\exp}({\ln}(D_1)(T_1/T_2)^{0.4495}+3.8535(1-(T_1/T_2)^{0.4495}))$, and in basal area growth, Schumacher polymorphic equation of $BA_2={\exp}({\ln}(BA_1)(T_1/T_2)^{0.1235}+11.3793(1-(T_1/T_2)^{0.1235}))$ showed the highest precision of the fitting among them. The equation, therefore, could be available as basic information for estimation of growth and management of Thuja orientalis stand.

본 연구는 천연기념물(62호)인 충북 영천리 측백나무(Thuja orientalis)림의 직경과 흉고단면적 생장모형을 추정하여 측백림의 관리에 필요한 기초 자료를 제공하고자 45본의 표준목을 선발하여 생장추를 이용하여 목편을 채취한 후 기초(non-overlapping) data와 데이터 재배열을 통한 overlapping data를 이용하여 최적의 흉고직경과 흉고단면적 추정식을 선정하였다. 동형 및 다형의 비선형 생장식을 데이터에 적합한 결과 overlapping data를 이용한 다형 방정식이 우수한 적합성을 보였다. 흉고직경 생장은 Schnmacher 다형 방정식인 $D_2={\exp}({\ln}(D_1)(T_1/T_2)^{0.4495}+3.8535(1-(T_1/T_2)^{0.4495}))$, 흉고단면적 생장은 Schnmacher 다형 방정식인 $BA_2={\exp}({\ln}(BA_1)(T_1/T_2)^{0.1235}+11.3793(1-(T_1/T_2)^{0.1235}))$가 가장 우수한 식으로 판명되었다. 본 연구에서 제시된 측백림의 흉고직경과 흉고단면적 생장식은 천연기념물인 측백림의 관리 경영에 필요한 정보로 이용할 수 있을 것으로 판단된다.
