Abstract
The valley forests at Baraebong area, Jirisan National Park were studied to investigate forest structure of tree, subtree and shrub layers in relation to aspect and altitude of the slope. Density and basal area of the tree layer in the north-facing slope were greater than those in the south-facing slope. As elevation increased, basal area of the tree layer decreased in north-facing slope. The impotance percentage of Quercus mongolica increased with increasing elevation while those of Quercus serrata and Pinus densiflora decreased. Species diversity of the north-facing slope was 1.307 and that of the south-facing slope was 1.114. There was a tendency that number of species, species diversity and evenness decreased with increasing elevation. The result of cluster analysis for the tree and subtree layer indicated that the studied forests were classified into Quercus senrraa-broad-leaved tree species community at the low and middle elevation belts of the south-facing slope, Quercus mongolika-broad-leaved tree species community at the high elevation belt of the south-facing slope, the middle and high elevation belts of the north-facing slope and top area, and Pinus densiflora-Quercus mangolica community at the low elevation belt of the north-facing slope. There were significantly positive correlations in the importance percentages among Carpinus laxiflora, Quercus serrata, Styrax obassica and Linden obtuiloba, and among Castanea crenata, Rhodndendron schippen-bachii and Vibntnum erosum.
