Abstract

This study was conducted to provide the informations for conservation and effective management of Picea yezoensis community in Mt. Deogyu and Mt. Gyebang. The vegetation of tree, subtree and shrub layer was consist of 8, 20, 26 species in Mt. Deogyu, and 12, 23, 33 species in Mt. Gyebang. Importance value by layer P. yezoensis, Betula ermanii, Abies koreana at tree layer, B. ermanii, Quercus mongolica at subtree layer, and Sasa borealis at shrub layer in Mt. Deogyu, and P. yezoensis, B. ermanii, Abies nephrolepis at tree layer, Acer komarovii and A. ukurunduense at subtree layer, and Tripterygium regelii at shrub layer in Mt. Gyebang were high, respectively. Species diversity in Mt. Deogyu and Mt. Gyebang were 0.779 and 0.984 at tree layer, 1.052 and 1.161 at subtree layer, and 0.823 and 1.304 at shrub layer, respectively. According to the DBH class of major species, P. yezoensis in Mt. Deogyu showed a reverse J-shaped curve, which was estimated that P. yezoensis community of this site might be maintained continuously as a stable state.

본 연구는 덕유산, 계방산의 가문비나무 군락의 보존을 위한 기초자료를 제시하기 위하여 종조성과 흉고직경급을 조사, 분석하였다. 두 조사지의 교목 아교목 관목층의 층위별 식생은 덕유산이 8, 20, 26종, 계방산이 12, 23, 33종으로 구성되어 있다. 층위별 중요치 분석 결과, 덕유산 교목층은 가문비나무, 사스래나무, 구상나무, 아교목층은 사스래나무, 신갈나무, 관목층은 조릿대가 중요치가 높았으며, 계방산의 교목층은 가문비나무, 사스래나무, 분비나무, 아교목층은 시닥나무, 부게꽃나무, 관목층은 미역줄나무의 중요치가 가장 높은 것으로 분석되었다. 조사구의 층위별 종다양도의 경우 교목층은 덕유산 0.779, 계방산 0.984, 아교목층은 덕유산 1.052, 게방산 1.161, 관목층은 덕유산 0.823, 계방산 1.304로 분석되었다. 흉고직경 분포에서는 덕유산지역의 가문비나무 개체군이 역J형의 유형이 나타나고 있어 당분간 가문비나무군락이 유지될 수 있을 것으로 판단된다.
