Abstract

Vegetational data obtained from 15 quadrats of Mt. Daeam area were analysed by applying two multivariate methods : two-way indicator species analysis(TWINSPAN) for classification and detrended canonical correspondence analysis(DCCA) for ordination. The dominant tree species were Quercus mongolica, Acer pseudo-sieboldianum, Betula costata, and Acer mono in descending order. The pH ranges were 5.0 to 5.5 in the 15 sites near bog and 5.3 to 5.4 in the 3 sites within bog. The forest communities in Mt. Daeam were classified into Quercus mongolica-Acer mono, Quercus mongolica-Prunus sargentii, Quercus mongolica-Abies nephrolepis-Acer tschonoskii var, rubripes, and Quercus mongolica-Abies nephrolepis-Betula costata according to the TWINSPAN. The relationships between the distribution of dominant species of forest vegetation and soil in the forest of Mt. Daeam were investigated by analyzing soil nutrition gradient. Quercus mongolica-Prunus sargentii forests were distributed in the good sites in nutrition levels of total nitrogen, cation exchange capacity, $Mg^{+{+}}$ and $Ca^{+{+}}$ but Quercus mongolica-Abies nephrolepis-Betula costata forests in the poor sites in the nutrition levels.

대암산(大岩山) 용늪 주변(周邊) 산림군집(森林群集)의 구조(構造) 및 종조성(種組成)과 입지(立地)와의 관계(關係)를 구명(究明)하기 위하여 TWINSPAN과 DCCA를 사용(使用)하여 분석(分析)한 결과(結果)는 다음과 같다. 중요치(重要値)가 높은 종(種)은 Quercus mongolica, Acer pseudo-sieboldianum, Betula costata, Acer mono 등(等)의 순(順)이다. 산림토양(森林土壤)의 pH는 용늪 주변(周邊)이 5.0-5.5이고 용늪 내에서 5.3-5.4로 차이가 없었다. 대암산(大岩山)의 산림군집(森林群集)은 Quercus mongolica-Acer mono, Quercus mongolica-Prunus sargentii, Quercus mongolica-Abies nephrolepis-Acer tschonoskii var. rubripes, Quercus mongolica-Abies nephrolepis-Betula costata의 4 group으로 나누어지며, 또한 주요(主要) 군집(群集)들과 환경(環境) 요인(要因)들과의 관계(關係)로 보면 신갈나무-산벚나무 군락이 전질소(全窒素), cation exchange capacity, $Mg^{+{+}}$, $Ca^{+{+}}$ 등(等)의 양료(養料)가 많은 곳에 주로 분포(分布)하고 있는 반면 신갈나무-분비나무-거제수나무 군락이 양료(養料)가 적은 곳에 분포(分布)하고 있다.
