지리산국립공원 제4기 자원조사 표본지 내 식물군집구조

The purpose of this study was to identify the phytosociological vegetation structure through a sampling survey of Mt. Jirisan National Park. And it was conducted to provide the latest data for establishing a conservation and management plan for forest ecosystems. As a result of TWINSPAN classification, it was classified into 4 communities. Group Ⅰ is the Fraxinus mandshurica - Acer pseudosieboldianum Community, group Ⅱ is the Quercus serrata - Quercus variabilis Community, group Ⅲ is the Quercus mongolica Community, group Ⅳ is the Pinus densiflora Community. Group Ⅰ is dominated by Fraxinus mandshurica in the canopy layer, and Cornus controversa and Quercus mongolica compete and maintain dominance. Group II is dominated by Quercus variabilis and Quercus serrata in canopy layer, and Styrax obassia and Styrax japonicus compete in sub-tree layer. In group Ⅲ, Quercus mongolica has a high dominance of 67% in canopy layer and 27% in the sub-tree layer, and Acer pseudosieboldianum competes with the Quercus mongolica in the sub-tree layer. In group Ⅳ, Pinus densiflora showed a high dominance of 74% in canopy layer. The sub-tree layer is dominated by Quercus mongolica, and is accompanied by competition between Carpinus tschonoskii and Fraxinus sieboldiana.
