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.
