Abstract

This text was analyzed and investigated the vegetation and floristic composition by ordination and classification of phytosociological method, to evaluate the species composition and community structure of Cymbidium goeringii group in Korean islets. In habitat of 33 plots, the mean altitude was 65.9m, the direction was the southeast slope, the mean slope was 7.9%. The coverage of Cymbidium goeringii was 4.5%. The appearing plants with the Cymbidium goeringii was the total 102 taxa, and it was the kind of trees 68 taxa (66.7%), herbs 34 taxa (33.3%), evergreen plants 36 taxa (35.3%) and deciduous plants 66 taxa (64.7 %) respectively. The frequency of appearing plant was the highest in the Eurya japonica (48.5%), followed by Pinus thunbergii (45.5%), Smilax china (36.4%), Carex lanceolata (33.3%), Hedera rhombea (33.3%), Machilus thunbergii (30.0%), Styrax japonicus (30.3%) and Pinus densiflora (27.3%), respectively. The vegetation of tree layer in Cymbidium goeringii group was classified into Pinus thunbergii community, Pinus densiflora community, Castanopsis sieboldii community and Quercus variabilis community. Pinus densiflora community showed a strong combination with Cymbidium goeringii group in Korean islets. Pinus thunbergii community among communities was combined with Castanopsis sieboldii community, and Pinus densiflora community and Quercus variabilis community were combined.

본 연구는 상관에 의한 종조성표의 불연속성인 분류법과 연속성인 배열법을 적용하여 한반도 도서지역 춘란 집단의 식물종조성 및 식생을 식물사회학적으로 분석하였다. 자생지 33개소는 평균 해발고도 65.9m이었고, 방향은 동남 사면이었으며, 경사는 평균 7.9%이었다. 조사구 $4m^2$ 면적의 춘란 피도는 4.5%이었다. 춘란과 동반 출현하는 식물은 총 102분류군이었다. 그 중 목본은 68분류군(66.7%)이었고, 초본은 34분류군(33.3%)이었으며, 상록식물은 36분류군(35.3%), 낙엽식물은 66분류군(64.7%)이었다. 춘란과 동반 출현하는 빈도가 가장 높은 식물은 사스레피나무(48.5%)이었으며, 다음으로 곰솔(45.5%), 청미래덩굴(36.4%), 그늘사초(33.3%), 송악(33.3%), 후박나무(30.0%), 때죽나무(30.3%), 소나무(27.3%) 순이었다. 춘란집단의 식물군락은 곰솔군락, 소나무군락, 구실잣밤나무군락, 굴참나무군락으로 구분되었으며, 춘란과 결합력이 강한 식물군락은 곰솔군락이었다. 춘란집단 식물군락의 유사성과 결합양상은 곰솔군락과 구실잣밤나무 군락이 가까웠고, 소나무군락은 굴참나무군락과 가까웠다.
