Abstract

The Taeanhaean National Park is the only seashore national park in Korea. To investigate the vegetation structure and characteristics of representative four islands such as Oedo, Janggodo, Godaedo and Gauido in Taeanhaean National Park, sixteen plots(size is $100mm^2$) were set up, and four plots were set up in each island. In the result of vegetation structure analysis of each island, Oedo and Janggodo was dominated by Pinus thunbergii community, and Godaedo was dominated by P. thunbergii-P. densiflora community and Gauido was dominated by Carpinus turczaninovii-P. densiflora community. But according to the physical environment of each island, there was a subtle difference in species composition even though the same P. thunbergii or P. densiflora community. The analysis of ordination and similarity turned out that the degree of similarity was lowest(6.58%) between Oedo and Gauido. The analysis result of species diversity and number of individuals shows that Gauido had high species diversity (2.7183) than the other islands.

태안해안국립공원은 우리나라 유일의 해안국립공원으로 대표적인 4개 섬인 외도, 대도, 장고도, 그리고 가의도에 대해 식생특성을 밝혔다. 각 섬마다 식생구조를 밝히고 비교를 하기 위하여 단위면적 $100mm^2$의 조사구 4개씩을 균등하게 설치하였다. 4개 섬에 대해 각각의 식생구조를 분석한 결과 외도와 장고도는 곰솔군락이 우점종이었으며, 고대도는 곰솔-소나무군락, 가의도는 소사나무-소나무군락이 우점종이었다. 그러나 각 섬의 물리적 환경에 따라 같은 곰솔이나 소나무군락이라도 종조성에 따라 차이가 있었다. Ordination과 유사도분석결과 외도와 가의도의 유사도가 6.58%로 가장 낮았으며, 종다양도(2.7183) 및 개체수 분석 결과 가의도가 가장 높은 것으로 나타났다.
