ABSTRACT

This study was carried out to classify forest vegetation structure of Jeoksansan in Deogyusan National Park from September 2007 to July 2008 using the DCCA ordination and phytosociological method. The vegetation of the Jeoksangsan was classified into Quercus mongolica community, Pinus densiflora community, Q. variabilis community, Q. serrata community, Carpinus laxiflora community and Fraxinus mandshurica community. Ecological characteristics such as species composition, layer structure, vegetation ratio, and the distribution of individual trees by DBH were significantly different among communities. The order of important value of the forest community with DBH 2cm above plants was Q. mongolica( 63.31), P. densiflora(40.47), Q. variabilis(34.75), Q. serrata(24.37), C. laxiflora(16.35), Carpinus cordata(14.81), Styrax obassia(14.50), F. mandshurica(13.88) and Acer pseudo-sieboldianum(12.99). Size-frequency distribution(DBH) of P. densiflora had a binomial distribution, suggesting a continuous domination of these species over the other species for the time being. In contrast, Q. serrata had a higher frequency of young individuals. C. laxiflora, C. cordata and F. mandshurica is likely that the dominance of these species will be increased in the future. Q. mongolica and Q. variabilis had a higher frequency of young individuals and middle frequency, suggesting a continuous domination of these species over the other species for the time being In contrast. This study examined the correlation between each community and the environment according to DCCA ordination. The Q. mongolica community and Fraxinus mandshurica community predominated in the highest elevation highest altitude which had a fertile soil whereas the P. densiflora community mainly occurred in the low elevation habitats which had an infertile soil. Q. variabilis community and Q. serrata community predominated in the low elevation and on the southern slope of the park habitats which had an infertile soil. The C. laxiflora community appeared on the northern slope of the park in the middle elevation.
