본 연구는 한려해상국립공원 동부지역에 위치한 5개의 특정도서지역(소치도, 장도, 세존도, 솔섬, 학섬)의 관속식물상을 2011년 4월부터 2012년 10월까지 총 50회에 걸쳐 조사를 실시하였다. 장도에서 관속식물의 출현은 특산식물 1분류군, 귀화식물 10분류군, 희귀식물 1종을 포함하여 총 52과 102속 11종11변종 2품종 124분류군 이 조사되었으며, 학섬에서는 44과 73속 76종 8변종 84분류군이 출현하였고 특산식물 3분류군 귀화식물 5분류군을 포함하고 있었다. 소치도에서의 관속식물은 38과 51속 51종 8변종 59분류군이 출현하였고, 귀화식물 3분류군, 희귀식물 3분류군이 조사되었다. 솔섬에서는 귀화식물 1종, 희귀식물 2분류군을 포함하여 28과 28속 24종 4변종 28분류군, 세존도에서는 귀화식물 1종, 희귀식물 1종을 포함하여 15과 19속 16종 4변종 20분류군이 출현하였다. 식물구계학적 특정식물은 I등급 46종, II등급 1종, III등급 16종, Ⅳ등급 2종, Ⅴ등급 4종이 출현하였다.
This study was carried out to investigate the distribution of vascular plants growing at five specific islands located in Hallyeohaesang National Park such as Sochi-do, Jang-do, Sejon-do, Sol-seom, and Hak-seom. The vascular floras were surveyed a total of 50 times including the preliminary investigation from April 2011 to October 2012. The flora of Jang-do was investigated as a total of 124 taxa comprising of 52 families, 102 genus, 111 species, 11 varieties, and 2 forma including 2 taxa of the endemic plants, 10 taxa of the naturalized plants, and 1 taxon of the korean rare and endangered plant species. At Hak-seom investigation, a total of 84 taxa were investigated as 44 families, 73 genus, 76 species, and 8 varieties. The endemic plants and naturalized plants at Hak-seom were 3 taxa and 5 taxa, respectively. The flora of Sochi-do was classified as a total of 59 taxa consisting of 38 families, 51 genus, 51 species, and 8 varieties along with 3 taxa of the naturalized plants and 3 taxa of the korean rare and endangered plant species. The Sol-seom was consisted of a total of 28 taxa comprising of 28 families, 28 genus, 24 species, and 4 varieties including 1 taxon of the naturalized plants and 2 taxa of the korean rare and endangered plant species. At Sejon-do inspection, a total of 20 taxa comprising of 15 families, 19 genus, 16 species, and 4 varieties were investigated. 1 taxon of the naturalized plants and 1 taxon of the korean rare and endangered plant species were investigated at Sejon-do. The floristic special plants at five specific islands located in Hallyeohaesang National Park were a total of 69 taxa such as 46 species in class I, 1 species in class II, 16 species in class III, 2 species in class Ⅳ, and 4 species in class Ⅴ.
