In this study, 28 plots(400㎡) were set up to understand the flora and vegetation structure of Jangbok-Woongsan Section. As a result of classifying the plant community, 28 survey plots were classified into 2 clusters. It was classified into two groups: Pinus thunbergii-Quercus dentata Quercus dentata-Pinus thunbergii -Platycarya strobilacea group community. In the correlation between species, it showed a strong positive correlation such as between: Carpinus tschonoskii and Quercus variabilis, Quercus dentata, Populus davidiana, Quercus acutissima; Quercus variabilis and Populus davidiana, Quercus acutissima; Platycarya strobilacea and Prunus sargentii; Quercus dentata and Quercus acutissima;Populus davidiana and Quercus acutissima; Pinus densiflora and Quercus mongolica. Strong negative correlation was shown as follows: Quercus aliena and Quercus dentata. The Species diversity(H') of investigated groups were ranged from 0.6269 to 1.2785.
Vascular plants were investigated a total of 715 taxa including 114 families, 383 genera, 620 species, 4 sub-species, 76 varieties, and 15 forms. It accounted for 14.6% of vascular plants(4,881 species) in Korea. The list of rare plants surveyed to be 14 taxa including 13 families, 13 genera, 13 species and 1 varieties. The endemic plants to Korea were surveyed to be 13 taxa including 10 families, 13 genera, 12 species and 1 varieties. The floristic special plants were surveyed to be 89 taxa including 44 families, 77 genera, 83 species, and 6 varieties and Naturalized plant species were 53 taxa including 16 families, 41 genera, 52 species, and 1 varieties.
