This investgation was performed to provide basic data for the management program of the Soraksan national park. Sixty plots were set up and surveyed in the Sinhungsa-Wasondae Area. The vegetation was divided into two communities, Pinus densiflora community and Quercus serrata community, according to the analysis of DCA ordination. It was found out that the succession of the Pinus densiflora comunity would proceed to Quercus serrata community of which components was dominant in understory layer and shrub layer. And it was found out that in the Quercus serrata community the Pinus densiflora being mainly big size in DBH would becomr dominant comtinuously. Shannon's diversity of both community were 1.2554 and 1.1134 respectively. The numbers of woody species per 100m$^{2}$ ranged 7 to 26, and the average number of woody species was 13.

계룡산국립공원 동학사-남매탑구간의 산림군집구조를 분석하기 위하여 64개 조사구를 설정하고 식생구조를 실시하였다. Classification의 기법 중 하나인 TWINSPAN을 이용하여 군집분리를 시도하였으며, 그 결과 소나무 군집(I), 굴참나무-소나무군집(II), 서어나무-굴참나무군집(III), 굴참나무-졸참나무군집(IV), 서어나무-까지박달군집(V), 신갈나무-서어나무군집(VI), 느티나무-졸참나무군집(VII) 그리고 느티나무군집(VIII)의 8개로 분리되었다. 연륜분석결과 이지역의 임령은 약 60년 안팍이었으며, 단위면적(100$\m^2$)당 평균출현종수는 15.0$\pm$3.2종. 평균출현개체수는 95.7$\pm$37.3주었다. 이상의 결과를 통해 계룡산국립공원이 동학사-남매탑구간 지역은 소나무림에서 굴참나무, 졸참나무, 신갈나무림을 거쳐 서어나무, 까지박달림으로 천이가 진행될것으로 예상되었다.

본 연구는 계룡산국립공원 동학사 계곡의 식물군집구조를 파악하기 위하여 실시되었으며, 10cm$\times$10m(100$\m^2$) 조사구를 52개 설정하여 식생조사를 실시하였다. 52개 조사구는 TWINSPAN에 의한 classifi-cation 분석과 DCA ordination 분석을 통하여 소나무군집(16개 조사구), 밤나무군집(4개 조사구), 신갈나무군집(5개 조사구), 졸참나무군집(13개 조사구), 느티나무군집(4개 군집), 서어나무군집(10개 조사구)으로 나누어졌다. 6개 군집의 천이경향을 살펴보면 소나무군집, 신갈나무군집, 졸참나무군집,느티나무군집은 각 층위별 안정된 층위구조로 현상태를 유지할 것이며, 밤나무구닙은 참나무류를 거쳐 서어나무로의 천이가 진행될 것으로 판단되었고, 서어나무군집은 졸참나무와 굴참나무군집으로 퇴행천이될 것이다. 6개 군집의 Shannon의 종다양도지수는 1.2732~1.4699이었다.

To investigate the actual vegetation in Sokri mountain area, which consists of Sokri Mt. National Park, forest communities were classified by phytosocialogical analysis according to species composition and physiognomy. Actual vegetation map was drawn on the basis of classified forest communities. The forest communities in Mt. Sokri were classified as follows : 1. Pinus densiflora community 1) P. densiflora-Rhododedron mucronulatum subcommunity 2) P. densiflora-Rhododendron schippenbachii subcomminity 3) P. densiflora-Lespedeza maximowiczii subcommunity 4) P. densiflora-Sasa borealis subcommunity 2. P. densiflora-Quercus serrata community 3. P. densiflora-Q. variabilis community 4. Quercus serrata community 5. Q. serrata-Q. variabilis community 6. Carpinus laxiflora community 7.

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.

거제도 노자산지역의 식물군집구조를 파악하기 위해 43개 조사구(각 조사구당 10m$\times$10m)를 거제휴양림 임도 주변과 노자산 북사면에 설정하고 식생조사를 실시하였다. 식생조사자료를 이용 TWINSPAN에 의한 classification과 DCA에 의한 ordinationqnstjr을 실시하였다. TWINSPAN분석과 DCA분석 결과 소사나무군집(군집I), 소나무군집(군집II), 졸참나무군집(군집(III), 고로쇠나무, 느티나무, 비목나무, 까치박달 등을 우점종으로 하는 낙엽활엽수군집(군집IV)의 4개 군집으로 분리되었다. 식물군집구조 분석 결과 노자산지역의 식생은 소나무$\longrightarrow$졸참나무군집$\longrightarrow$낙엽활엽수군집으로 생태적 천이가 이루어질 것으로 판단되었으며, 소사나무군집은 해발고도가 높고 건조한 지역에 나타나는 토지극상으로 판단되었다.

This study was carried out to investigate the ecological succession sere and conservative value, and to provide the basic data in Woonsooam Valley, in Jogyesan (Mt.) (altitude 884m), Suncheon City, Korea by analysing the structure of the plant community. Fifteen plots (size is $20m{\times}20m$) were set up at an altitude of range from 255m to 495m. As a result of analysis of DCA which is one of the ordination technique, the plant communities were divided into five groups which are community I (Pinus densiflora community), community II (Quercus variabilis-Quercus serrata community), community III (Q. serrata-Q. variabilis community), and community IV (Carpinus tschonoskii-Q. serrata community) and community v(Deciduous broad-leaved forest community). We found out that the vegetation of the study site located in the South Temperate Climate Zone. The study site is found out that Q. serrata community 34.4%, part of slope in valley is the distribution that dominant species is Q. serrata-Q. variabilis community 32.1%. And in valley showed Carpinus tschonoskii community 5.5%. And Sasa borealis was dominant species in the shrub layer. We couldn't supposed that the ecological succession sere of the study site, however we should do a long-term monitoring to investigate the changes of the ecological succession each plant community, According to the index of Shannon's diversity (unit: $400m^2$), community III was ranged from 1.0102 to 1.1013, community V was 0.9945, community II was ranged from 0.7913 to 1.1503, community IV was ranged from 0.8081 to 1.0749 and community I was 0.9273.
