Abstract

This study was carried out to offer a basis data for application of effective management through species composition and community structure of Castanopsis cuspidata var. thunbergii stands (Bijindo and Yokjido). The upper, middle and lower layer in Bijindo and Yokjido consisted of 10, 11 and 27 species, and 9, 6 and 28 species, respectively. The importance value of Castanopsis cuspidata var. thunbergii were highest in upper and middle layer both two studied site. The herbaceous species were 33 and 47 species in Bijindo and Yokjido, respectively. The species diversity ranged from 0.523 to 1.280 in Bijindo and 0.699 to 1.364 in Yokjido. Dominance in Bijindo and Yokjido were 0.477 and 0.242 at upper layer, 0.231 and 0.102 at middle layer, and 0.106 and 0.057 at lower layer, which showed that Castanopsis cuspidata var. thunbergii stands are dominated by a large number of species at all layer. The distribution pattern by Morisita's index showed that Castanopsis cuspidata var. thunbergii was distributed randomly in upper layer both the studied sites.

비진도와 욕지도에 군락을 형성하고 있는 모밀잣밤나무림의 종 조성과 군락구조 분석을 통하여 효과적인 관리를 위한 기초적인 정보를 제공하기 위한 조사가 이루어졌다. 비진도와 욕지도 상 중 하층에 출현한 식물은 각각 10, 11, 27종과 9, 6, 28종으로 조사되었다. 두 조사지 모두 상.중층에서 모밀잣밤나무의 중요치가 가장 높게 나타났다. 초본식물은 비진도에서 33종, 욕지도에서 47종이 출현하였다. 종다양도는 비진도 모밀잣밤나무군락이 $0.523{\sim}1.280$, 욕지도 지역이 $0.699{\sim}1.364$로 분석되었으며, 우점도는 전층에서 0.5이하의 값을 나타내어 비진도와 욕지도 모밀잣밤나무군락은 다수의 종에 의해 우점되어 있다는 것을 알 수 있었다. Morisita 지수에 의한 모밀잣밤나무의 분포패턴은 두 조사 지역 모두 상층에서 임의분포하는 것으로 나타났다.
