다국어 초록 (Multilingual Abstract)

The flora and vegetation of Hongdo Island were investigated three times from August 24th to August 31th in 1984, from April 20th to April 25th in 1985 and August 1st to August 8th in 1985. The vascular plants identified in these investigation were 104 families, 265 genera, 342 species, 45 varieties and 5 formae, summing up to 390 species total. When the lists of these species were compared with those reported previously by Lee(1959), and Lee and Kim(1968), 269 species were found to be the common identity and total number of species of Hongdo so far listed were summarized to be 105 families, 329 genera and 534 species.
The units of vegetation were classified into 3 associations (Bulbophylumo - Castanopsietum cuspidata var. thunbergii, Raphiolepio - carpinetum coreana, Ardisio - Camellietum japonica) and 8 communities(Pinus densiflora, Artemisia prienceps var. orientalis, Pseudosasa japonica, Aucuba japonica, Quercus acuta, Mallotus japonicus, Quercus dentata, Miscanthus sinensis). Therefore it was concluded that the vegetation of Hongdo belonged to Castanopsion cuspidata var. thunbergii alliance of the warm-temperate zone.
The vegetation of Hongdo could be mapped with 15 divided area such as cultivated area, open space, mixed forest, Castanopsis cuspidata var. thunbergii, Pinus densiflora, Camellia japonica, Quercus acuta, Aucuba japonica, Quercus dentata, Artemisia prienceps var. orientalis, Miscanthus sinensis, Carpinus coreana, Mallotus japonicus, Pseudosasa japonica and Pinus thunbergii.
