pp.468-486
연도에 분포하는 관속식물은 107과 312속 408종 2아종 51변종 5품종으로 총 466종류가 확인되었다. 이 중 소귀나무를 포함 39종류가 상록활엽수였으며, 식물구계학적 특정식물종은 I 등급에 53종류, II 등급에 1종류, III등급에 26종류, IV 등급에 3종류, V 등급에 애기등, 섬천남성 2종류가 확인되어 46과 70속 80종 5변종으로 85종류가 분포하는 것으로 조사되었다. 귀화식물은 13과 37속 40종 2변종으로 총 42분류군이 분포하였으며, 귀화율은 9.01%, 도시화지수는 14.63%로 분석되었다. 생활형조성은 H-Dl-R5-e type을 보였다. 연도의 식생은 곰솔군락(Pinus thunbergii community)과 구실잣밤나무군락(Castanopsis sieboldii community)이 분포되어 있고, 휴경지와 완경사 산지에 억새군락(Miscanthus sinesis var. purpurascens community)이 분포하였다.
It was found that vascular plants distributed at Yeondo islet were composed of 107 families, 312 genera, 408 species, 2 subspecies, 51 varieties and 5 forms, totaling 466 taxa. 39 species including Myrica rubra among the 466 taxa were evergreen broad-leaved tree, and as for flora region science-based specially designated plants by the Ministry of Environment, it was surveyed that 85 taxa(46 families, 70 genera, 80 species and 5 varieties) were distributed by identifying 53 taxa in grade one, 1 taxa in grade two, 26 taxa in grade three, 3 taxa in grade four, and Milletia japonica and Arisaema negishii in grade five. In the naturalized plants, a total of 42 taxa(13 families, 37 genera, 40 species and 2 varieties) were surveyed to be distributed and the ratio of their naturalization and Urbanization Index was analyzed to be 9.01% and 14.63%, respectively. Life form spectra bore a type of H-Dl-R5-e. Vegetation of Yeondo islet are classified as Pinus thunbergii community and Castanopsis sieboldii community, and Miscanthus sinesis var. purpurascens community spread on an gently slanted mountain side.
