Abstract

Baekdudan has 670km long within South Korea, so the study for detail vegetation characteristics is needed. In this study, we surveyed the plant community structure from Daetjae to Baekbongryung for the next restoration and management plan. We designated 40 quadrats ($10m{\times}10m(100m^2)$ for this study. As a result of TWINSPAN, plant community separated 8 different communities such as Abies koreana comm., Pinus densiflora comm., Quercus mongolica comm. and Larix kaempferi comm. etc. Abies koreana comm. and Pinus densiflora comm. which is mainly located in the mountain ridge and near rocks are needed avoidance from the competition with Quercus mongolica comm. The possibility of atrophy of these communities is to be high, the protection is needed. Species diversity index was between 0.8046~1.1283. Most communities have multi-layer structure and have the ecological value of protection.

백두대간은 남한구간만 약 670km로 전체 지역에 대한 생태적 특성을 파악하기는 어려워 각 지역에 대한 상세한 연구가 지속적으로 수행되어야 한다. 이에 본 연구는 백두대간 구간 중 댓재에서 백봉령구간의 식생구조를 밝히고 향후 복원 및 관리계획 수립시 필요한 기초자료를 제시하고자 마루금을 중심으로 $10m{\times}10m(100m^2)$ 조사구 40개소를 설치하였다. TWINSPAN에 의한 군집분류 결과 구상나무군집, 소나무 우점군집, 신갈나무 우점군집, 일본잎갈나무 우점군집 등 8개로 유형화되었다. 구상나무군집과 소나무군집은 신갈나무와의 경쟁을 회피할 수 있는 능선부 또는 암반지대에 분포하였으나 낙엽활엽수와의 경쟁으로 쇠퇴할 가능성이 높아 보호의 필요성이 있었다. 단위면적당($400m^2$) 종다양도는 0.8046~1.1283이었으며 단일종 우점군집이 낮고 경쟁상태인 군집은 높은 것으로 나타났으며 대부분 층위구조가 형성된 보호가치가 있는 숲이었다.
