Abstract

This study was carried out to provide the basic information for effective preservation and management of forest community of Nari basin in Ulleung Island. Forest community in Nari basin was classified into Fagus engleriana community, Sorbus amurensis community, Pinus densiflora community, Celtis jessoensis community and Alnus maximowiczii community. As the result of DCCA ordination analysis, sea level among environmental factors had high correlation with community distribution. Fagus engleriana community and Sorbus amurensis community correlated highly with aspect, Na content, and C/N ratio. There was a high correlation between Celtis jessoensis community and the content of Ca and K. Alnus maximowiczii community was distributed in site where CEC content is high. Pinus densiflora community was distributed in site where the content of Ca and CEC is high.

본 연구는 울릉도 나리분지의 군락구조와 환경요인의 상관관계를 파악하여 산림식생의 보전 및 관리에 필요한 생태학적 기초자료를 제공하기 위하여 수행되었다. 나리분지의 산림군락은 너도밤나무군락, 당마가목군락, 소나무군락, 풍게나무군락, 두메오리나무군락으로 분류되었다. DCCA 분석 결과, 환경요인 중 해발이 군집의 분포에 영향을 미치는 인자인 것으로 나타났다. 너도밤나무군락과 당마가목군락은 방위, Na, C/N의 환경요인과 군락단위의 분포지가 높은 상관관계를 나타내었다. 풍게나무군락은 Ca, K 등과 상관관계가 높은 것으로 나타났으며, 두메오리나무군락은 CEC의 함량이 높은 입지에 분포하고 있었으며, 해발고와 높은 상관관계가 있었다. 소나무군락은 Ca, CEC의 함량이 높은 입지에 분포하는 것으로 나타났다.
