지리산국립공원 대원계곡의 삼림군집구조를 분석하여 국립공원관리의 기초자료를 제공하기 위하여 기조사지역(이경재 등, 1991)이외의 지역에 대해 39개 조사지(100m2)를 설정하고 식생조사를 실시하였다 Classification의 한 기법인 TWINSPAN을 사용하여 군집을 분리하였으며 그 결과 느릅나무-굴참나무군집(군집 I) 졸참나무-굴참나무군집(군집II) 졸참나무군집(군집III-V) 신갈나무군집(군집VI) 그리고 서어나무-노각나무군집(군집VII)의 7개 군집으로 나뉘었다 각 군집에 대해 우점도 종다양도 유사도 종수 및 개체수 그리고 흉고직경 등의 분석을 통해 군집의 종조서을 살펴본 결과 지리산 대원계곡의 삼림은 졸참나무 굴참나무 신갈나무 등의 참나무가 주류를 이루고 있었으며 점차 서어나무와 노각나무등으로 천이가 진행되어갈 것으로 판단되었다.

지리산국립공원 거림계곡 식물군집구조를 파악하기 위하여 거림계곡 내 등산로를 따라 66개(6,600m2)의 방형구를 설정하였으며 DCA 기법을 이용하여 분석한 결과 해발고 740-950m 의 조사구는 졸참나무군집(군집I) 해발 950-1,340m의 조사구는 신갈나무군집(군집II) 해발 1,340-1,390m의 조사구는 구상나무-거제수나무군집(군집III)으로 분류되었다 상대우점치 흉고직경급별 분포 분석결과 각 군집의 우점종인 졸참나무 신갈나무 구상나무가 우점하는 군집으로 계속유지될것으로 판단되었으며 특히 관목층은 조랫대의 밀도가 높아 천이진행에 영향을 주는 동시에 종다양도가 낮은 것으로 판단되었다 한편 3개 군집간의 유사도지수는 낮은 상태로 해발고에 따라 식생구분이 명확하였다

This study was intended to suggest the appropriate vegetation management methodology by analyzing phytosociology for ecotourism resources. We carried out the classification and interpretation of the vegetation structure and the analysis of the relationship between communities and environmental conditions in Pocheon valley, Mt. Gaya. The vegetation in Pocheon valley was composed of 5 communities: Pinus densiflora-Quercus mongolica community, Quercus serrata-Quercus variabilis community, Larix kaempferi-Quercus serrata community, Pinus densiflora-Castanea crenata community, and Salix gracilistyla-Phragmites japonica community. The Quercus serrata-Quercus variabilis community was further segmented into two types according to the differences of composition species and location of habitats. The methodologies that satisfy both the use of nature for ecotourism resources and the sustentation of natural vegetation are as follows: - maintenance the present vegetation (dominance species) by strictly avoiding artificial management in the tree layer; - maintenance of the existing vegetation structure through the artificial management of the usual vigorous tree species when the species in the shrub layer grow up to the subtree layer; and - continued artificial management to maintain high balanced diversity and evenness of various species in shrub and herb layers.

The Hwaomsa valley forest and the Piagol valley rarest in Mt. Chiri were studied to investigate forest structure and succession. Thirty plots in the Hwaomsa valley forest and thirty-nine plots in the Piagol valley forest were set up, and vegetation analysis of TWINSPAN classification and DCA ordination was carried out. The size of each plot was 20m $\times$ 25m, and the trees above 2cm DBH in each plot were measured. The Hwaomsa valley forest and the Piagol valley forest were classified into four communities and three communities by the altitude, respectively. The successional trends of major tree species seem to be from Pinus densiflora and Quercus mangalica through Quercus serrata to Carpinus spp. in the Hwaomsa valley forest. and from Quercus mongalica through Quercus serrata to Carpinus Spp. in the Piagol valley forest. The Hwaomsa valley is assumed to be interfered by the man more, and develop into the climax less than the Piagol rarest.

To investigate the plant community structure in valley and suggest the management of Mational Park, fifty plots were set up and surveyed in Jujeongol Valley, Soraksan National Park. The classification by TWINSPAN and DCA ordination technique were applied to the study area in order to classify them into several groups based on woody plants. The dividing groups were Quercus mpnngolica - Q. variabilis - Pinus densiflora community, P. densiflora community, Carpinus laxiflora community, Q. serrata community. The ecological trends of tree species by DCA ordination technique and DBH class distribution analysis was like that Q. mongolica - Q. variabilis - P. densiflora community and P. densiflora community seems to be trended from P. densiflora community to Q. mongolica community. Q. serrata community seems to be trended from Q. serrata community to C. laxiflora community and C. laxiflora will be maintaimed stable state.

To investigate the plant community structure of Paekdam-Valley in Soraksan National Park, fifty-two plots have been set up and surveyed. By DCA ordination technique, the plant communities were classified into fkve community types, which were Pinus densiflora community and Q. mongolica community. It was supposed that Q. serrata community change to C. laxiflora community. It seemed that P. densiflora community, deciduous broad-leaved mixed forest and Q. serrata community would not be replace by another woody species. And it seemed that C. laxiflora community succeeded to Q. serrata community, so it was similar to the typical ecological succession of natural forest in the middle temperate regions. The range of Shannon's diversity index was 0.9827~1.2946(Unit area : 400m$^2$) and that was over another Korean National Parks area relatively.

To investigate the forest structure of Guryongsa-Birobong area in Mt. Chiak, four districts were selected and forty-five plots were set up at the districts. The leading dominant species of District I, the valley forest in which users' density was very high. was Pinus densiflora. That of District II, the valley forest in which users' density was high. and Districs III, the valley forest in which entering was restricted recently. was Comus controversa. That of District III, the ridge forest in which users' density high, was Quercus mongolica. Species diversities of District I, II, III, and IV were 1.3252, 1.3736, 14421, and 1.2546, respectively. DCA ordination were showed that successional trends of tree species seem to be from Pinus densiflora through Quercus spp. to Carpinus laxtflora in ridge and midslope forest and from Pinus densiflora through Quercus spp. to Comtus controversa and Carpinus cordata.

The Chuwang valley-Kumunkwangi valley forest in Chuwangsan area was studied to investigate forest structure in relation to altitude and part of slope. Forty eight quadrats were set up in the valley forest along altitude of 470m to 780m and part of the slope. Density and basal area of trees in tree strata decreased as increasing elevation. With increasing elevation the importance values of Quercus mongolica, Fraxinus rhynchophylla increased, while those of Pinus densiflora, Lindera obtussiloba decreased. As going from lower part to upper part of the slope, the importance values of Quercus valiabilis and Lindera obtussiloba increased while those of Fraxius rhynchophylla, Acer mono decreased. Species diversity tended to decreased as going to upper parts of the slope. The range of similarity indices between elevation belts, and parts of the slope were 74.4~84.2% and 68.0~96.3%, respectively. According to importance value and cluster analysis, the studied valley forest was classified into three forest communities of Pinus densiflora-deciduous tree species community of lower part of slope, Pinus densiflora-Quercus variabilis community of middle and upper part of slope, Pinus densiflora community of the top area.
