전라북도 부안군ㆍ고창군 무인도서 식생에 관한 연구 = A Study on the Vegetation of Uninhabited Islands in Buangun and Gochanggun of Jeollabukdo

다국어 초록 (Multilingual Abstract)

Six field surveys were conducted from May to September of 2013 in order to identify vegetation and develop the current vegetation map of uninhabited islands in Buan-gun and Gochang-gun of Jeollabukdo. In total there were 30 uninhabited islands in Buan-gun and Gochang-gun, and vegetation was formed in 20 of them. Among the 20 uninhabited islands, 18 were located in Buan-gun and two in Mandol-ri, Simwon-myeon of Gochang-gun. Main vegetation of 20 uninhabited islands was Miscanthus sinensis var. purpurascens community of 15.87%, the Pinus thunbergii community 13.83%, and the Carpinus coreana community 6.00%. Those three communities accounted for 35.70% of the total area. The net vegetation area was 154,267.60m2, and was mostly dominated by these communities. Regarding vegetation diversity, Keunttanji Island had nine communities, and Jeungjo Island had five communities. Mogoe Island and Suribawi Island had four communities each. Since the number of communities in these islands ranged from one to five except for the Keunttanji Island, and the community diversity was relatively low. The Pinus thunbergii community and Miscanthus sinensis var. purpurascens community had a high origination rate. In the uninhabited islands where the Pinus thunbergii community was largely distributed, the distribution ratio of Pinus thunbergii community was high. A total of 22 communities were distributed in the 20 uninhabited islands. The number of herbaceous community, shrub community and subtree community were seven each, while the arboreal community was nine. Especially, in the Pinus thunbergii community most of those trees were planted and the Miscanthus sinensis var. purpurascens and Miscanthus sinensis community were formed by grazing. The Pseudosasa japonica and Phyllostachys bambusoides were planted around a structure that was constructed before for the purpose of management including grazing. As for the characteristic of overall vegetation in the 20 uninhabited islands, warm temperature communities were rare. Also, the distribution rate of planted or disturbed communities like the Pinus thunbergii and Miscanthus sinensis var. purpurascens was relatively high. Another characteristic was that the dune vegetation was rarely distributed. As the succession progresses, these uninhabited islands are expected to face an increase in the level of Eurya japonica, Camellia japonica, Raphiolepis umbellata and the Carpinus coreana community, all warm temperature species.
