This study was carried out to classify forest communities and to aggregate forest cover types for the complex and diversified natural forest areas of Guryongsan, Sobaeksan, Baekhwasan, Sokrisan, and Baekhaksan in the middle part of Baekdudaegan. The vegetation data were collected by point-centered quarter sampling method. One thousand one hundred fourteen sample points were subjected to cluster analysis to classify 27 forest communities, which were aggregated into 7 representative forest cover types on the basis of community similarity from composition of canopy species. They were Quercus mongolica forest cover type, mixed mesophytic forest cover type, Q. variabilis forest cover type, Pinus densiflora forest cover type, the others deciduous forest cover type, Q. serrata forest cover type, and subalpine forest cover type. The Q. mongolica forest cover type was most widely distributed in the study areas. It was assumed that abundance of Q. mongolica might be negatively associated with species diversity. Mixed mesophytic forest cover type and the others deciduous forest cover type were commonly distributed in the areas of valley, on the other hand, Q. mongolica cover type and P. densiflora cover type tended to be distributed in the areas of ridge.

가리왕산 일대 천연활엽수림을 대상으로 수행한 선행 연구에서 분류된 5개의 산림군집에 대하여 미래 수종 구성의 변화를 바탕으로 천이 경향을 추정하였다. 미래의 수종구성 변화의 예측은 Markov chain의 수학적 이론을 응용한 추이행렬모델을 이용하였다. 식생 표본구내에서 상층 우세목의 아래에서 생육하는 하층목에 의해서 세대가 교체될 것이라는 가정적 확률을 바탕으로 수종 구성의 변화를 예측하였다. 각 군집의 미래 수종 구성 변화를 예측한 결과, 신갈나무군집에서는 고로쇠나무, 물푸레나무, 피나무, 팥배나무가 상층을 우점할 것으로 예측되었다. 신갈나무-들메나무-물푸레나무군집에서는 고로쇠나무, 피나무, 물푸레나무, 복장나무가 우점할 것으로 예측되었다. 박달나무-신갈나무군집에서는 고로쇠나무, 물푸레나무, 피나무, 난티나무가 우점할 것으로 예측되었다. 중생혼합림에서는 고로쇠나무, 물푸레나무, 피나무, 복장나무가 우점할 것으로 예측되었다. 거제수나무-난티나무 군집에서는 고로쇠나무, 물푸레나무, 피나무가 우점할 것으로 예측되었다. 모든 군집의 중층에서는 당단풍나무의 우점이 크게 증가할 것으로 예측되었다. 현재 각 군집에서 상층을 우점하고 있는 신갈나무, 거제수나무, 박달나무의 우점은 줄어들고 고로쇠나무, 물푸레나무, 피나무 등의 수종이 우점하는 군집으로 발달해 갈 것으로 예측된다. For 5 forest communities which were previously classified by cluster analysis in the natural deciduous forest of Gariwangsan area, the successional trend was estimated from the change of species composition by transition matrix model. The model was modified from mathematical theory of Markov chain, examining the subsequent process of tree-by-tree replacement by understory saplings for the dominant canopy trees. Dominance of A. pictum subsp. mono, F. rhynchophylla, T. amurensis, and S. alnifolia was predicted to increase in overstory of Q. mongolica community. In Q. mongolica - F. mandshurica - F. rhynchophylla, dominance of A. pictum subsp. mono, T. amurensis, F. rhynchophylla and A. mandshuricum was predicted to increase in overstory. Dominance of A. pictum subsp. mono, F. rhynchophylla, T. amurensis, and U. laciniata was predicted to increase in overstory of B. schmidtii - Q. mongolica community. In Mixed mesophytic community, dominance of A. pictum subsp. mono, F. rhynchophylla, T. amurensis and A. mandshuricum was predicted to increase in overstory. Dominance of A. pictum subsp. mono, F. rhynchophylla and T. amurensis was predicted to increase in overstory of B. costata - U. laciniata community. Dominance of A. pseudosieboldianum was predicted to increase abruptly in midstory of all communities.

덕유산 백암봉 일대의 천연림을 대상으로 산림형을 구분하고, 각 산림형별 생태적 특성을 파악하여 천이경향을 제시하였다. 사분각법을 이용하여 225개의 표본점에서 식생자료를 수집하였으며, 다양한 다변량 통계분석(Cluster 분석, 지표종분석, 다중판별분석 등)을 실시하여 산림형을 구분하였다. 그 결과, 연구대상지는 5개의 산림형으로 분 류되었고, 상층의 우점비율 및 입지환경에 따라 능선부에서는 신갈나무림, 계곡부에서는 들메나무-물푸레나무-층층나 무림과 들메나무림, 사면하부에서는 졸참나무-소나무-신갈나무림, 소나무림 등이 분포하여 입지조건에 따라 수종구성 차이가 뚜렷한 것으로 나타났다. 산림유형별 생태적, 환경적 특성을 근거로 천이경향을 추정한 결과, 현재의 산림형은 신갈나무림, 들메나무림, 중생혼합림, 참나무-서어나무림 등으로 천이가 진행될 것으로 예상되었다. This study was carried out to classify the current forest cover types and to propose the successional trends in the natural forest of Mt. Deogyu. The vegetation data were collected by the point-centered quarter method. The forest cover types were classified by various multivariate statistical analysis methods such as cluster analysis, indicator species analysis and multiple discriminant analysis. This forests were classified into five forest types by the species composition of upper layer and topographic positions: Quercus mongolica forest in the ridge, Fraxinus mandushurica-F. rhynchophylla-Cornus controversa forest and F. mandushurica forest in the valley, the Q. serrata - Pinus densiflora - Q. mongolica forest and P. densiflora forest in the low-slope. As a result of the forest successional trends depending on ecological and environmental characteristics in each forest type, the current forest types were expected that the forest succession would be proceeded toward Q. mongolica forest, F. mandshurica forest, mixed mesophytic forest, and oak-Carpinus laxiflora forest.

We classified the forest type and figured out the ecological characteristics for each of the types in order to provide the basic informations for being induced ecologically efficient forest practice plan by vegetation units in the natural forest of Songnisan. We established the 250 sample points and collected the vegetation data of vertical distribution for each sample. A variety of multivariate statistical methods were applied to classify the forest types. The species diversity index were analyzed to estimate the stability and maturity for forest vegetation in each the type. The types were divided from two to ten clusters by cluster analysis. The appropriate number of clusters was estimated five clusters by indicator species analysis. It was verified through the multiple discriminant analysis that the estimated number of clusters had been suitable. Based on the species composition for each the type, this study site was classified into five forest types: 1) Quercus serrata and 2) mixed mesophytic forest in the valley area, 3) Q. mongolica forest in the main ridge, 4) Pinus densiflora forest in the sub-ridge extending from the main, and 5) Q. variabilis-P. densiflora forest between the sub-ridge and valley. The species diversity index of the pine forest that had been a simple species composition was the lowest while that of the mixed mesophytic forest of which the composition had been diverse was the highest. As the forest vegetation was more varied, the index showed a tendency to increase.

The purpose of this study was to interpret ecological characteristics and to estimate successional trendfor seven classified forest cover types (Quercus mongolica pure forest, Q. mongolica-Q. serrata forest, Mixedmesophytic forest, Abies koreana-Q. mongolica forest, Fraxinus mandshurica forest, Q. serrata forest, andCarpinus laxiflora forest) in the natural forest of Western Jirisan. Q. mongolica pure forest and A. koreana-Q. mongolica forest which were distributed in a high-altitude ridge had the lowest species diversity index. On theother hand, mixed mesophytic forest and F. mandshurica forest which were mainly distributed in the valley hadhigher index. Based on characteristics of species diversity and topographic conditions, successional trends forforest cover types were estimated as follows; 1) Q. mongolica pure forest and A. koreana-Q. mongolica forestwould be changed toward Q. mongolica-A. koreana forest. 2) Q. mongolica-Q. serrata forest, distributed betweenridge and mid-slope, would be changed toward Q. mongolica-C. laxiflora-C. cordata forest. 3) Q. serrata forest,distributed in mid-slope, would be changed toward Q. serrata-Q. mongolica-C. laxiflora forest. 4) Mixed mesophyticforest, F. mandshurica forest and C. laxiflora forest, distributed in valley, would maintain the current conditionin terms of species composition.

향로봉 일대는 한국전쟁 당시 격전지로서 식생의 파괴가 매우 심했던 곳이지만, 휴전 후 반세기 동안 인위적인 교란 없이 자연적인 천이과정을 거쳐 현재의 산림상태를 유지하고 있는 독특한 산림구조를 가지고 있다. 본 연구는 인위적 교란을 받은 산림의 피복유형을 분류하고, 피복유형 분류에 가장 큰 영향을 끼치는 수종을 알아보는 것에 그 목적이 있다. 점표본법으로 수집된 식생자료를 바탕으로 계층적 군집분석, 지표종분석, 다중판별분석 등 다변량 통계 분석법을 이용하여 식생자료를 분석하였다. 연구대상지를 2~10개의 클러스터로 분류하였고, 지표종분석을 통해 연구대상지의 적정클러스터 수는 5개인 것으로 파악되었다. 이를 통계적으로 검증하기 위해 다중판별분석을 실시하였고, 91.3%가 정확하게 분류되어, 연구대상지 산림 피복형의 개수는 5개가 적당한 것으로 나타났다. 각 클러스터 상층의 우점수종 비율에 따라 신갈나무순림, 신갈나무림, 신갈나무-잣나무림, 신갈나무-피나무림, 신갈나무-음나무-거제수나무림으로 산림 피복형을 명명하였으며, 신갈나무의 점유비율이 산림 피복형 명명에 큰 영향을 미치는 것으로 나타났다. The Hyangnobong area was a battlefield during the Korean War and where the forest vegetation had been severely destroyed. However, this forest has a distinctive forest structure that has been maintaining a current forest condition following the natural succession process for a half century after the armistice agreement. This study was conducted to classify the forest cover types formerly disturbed forest and recognize the species which has a strong influence on classifying forest cover types. The collected vegetation data by point quarter sampling method were analyzed using the multivariate statistical analysis such as hierarchical cluster analysis (HCA), indicator species analysis (ISA), and multiple discriminant analysis (MDA). The study area was classified into 2 to 10 clusters and ISA indicated that the optimal number of clusters was five. MDA was taken to test the number of cluster that classified with HCA and ISA. The five clusters were most appropriate to the overall successful classification with the 91.3 % of probability. The classified forest cover types were named by the ratio of the dominant species in the upper layer of each cluster; Quercus mongolica pure forest, Q. mongolica forest, Q. mongolica-Pinus koraiensis, Q. mongolica-Tilia amunensis, and Q. mongolica-Kalopanax septemlobus-Betula costata. The compositional ratio of Q. mongolica had an important effect to designate forest cover types.
