Floristic composition and phytosociological studies in Mt. Gwaebyung and Galmi-Bong were investigated to classify forest vegetation and distribution of vascular plants. We investigated two study sites from April to September, 2011. Total 477 taxa with 93 families, 279 genera, 408 species, 4 subspecies, 56 varieties and 9 forms were distributed in Mt. Gwaebyung and Galmi-Bong. Korean endemic species were composed of 8 families with 11 genera and 11 species. The plant species which is designated as protected species by the Ministry of Environment, Korea was 2 families, 2 genera and 2 species. Also plant species which is designated by the Korea National Arboretum was 16 taxa with 13 families, 14 genera, 15 species and 1 variety. A naturalized plants were 17 taxa. The Naturalization index and Urbanization index were 3.6% and 5.3% respectively. Pteridophyta-calculation (Pte-Q) was 1.00. Life form spectra was $H-D_4-R_5-e$ type and the highest percentage of useful plant resources were medicinal plant (77.5%). The forest vegetation in Mt. Gwaebyung and Galmi-bong was classified into 1 order, 1 alliance and 4 communities; Rhododendro - Quercetalia mongoliaceae, Lindero-Quercion mongolicae, Quercus mongolica Typical Community, Pinus densiflora-Quercus mongolica Community, Larix kaempferi Community and Sasa borealis-Quercus mongolica Community.
