Phytosociological Community Classification of Mountain Ridge from Guryongryeong to Mt. Yaksu in the Baekdudaegan, Korea

초록

To investigate the vegetation structure of mountain ridge from Guryongryeong to Mt. Yaksu, 22 plots (100㎡) installed with random sampling method were surveyed. Three groups of Quercus mongolica-Acer pseudosieboldianum community, Q. mongolica community, Cornus controversa-Q. mongolica community were classified by cluster analysis. Q. mongolica was a major woody plant species in the ridge area from Guryongryeong to Yaksusan and Carpinus cordata and C. controversa was partly occupied in some area. High positive correlations showed between Q. mongolica and Symplocos chinensis for. pilosa, Rhododendron schlippenbachii; Tilia amurensis and Tilia mandshurica, Symplocos chinensis for. pilosa; Tilia mandshurica and S. chinensis for. pilosa, R. schlippenbachii; Betula costata and Acer mono; Symplocos chinensis for. pilosa and Rhododendron schlippenbachii, and relatively high negative correlations showed between A. pseudosieboldianum and S. chinensis for. pilosa, R. schlippenbachii. Species diversity(H') of investigated groups were ranged 0.8170～1.1446 and it was lower compared to those of the ridge area of the national parks in Baekdudaegan.
