Employing the relev$\acute{e}$ method of Muller-Dombois & Ellenberg and Braun-Blanquet, 100 plots were sampled in the Quercus mongolica community of Mt. Odae, Mt. Chumbong and Mt. Jungwang in Kangwon-do. To analyze the data, phytosociological method and TWINSPAN were used. 1. Quercus mongolica forests were recognized as Quercus mongolica-Acer pseudosieboldianum community group, and were classified into Quercus mongolica-Carpinus cordata community, Quercus mongolica-Acer pseudosieboldianum typical community, Quercus mongolica-Lespedeza maximocoiczii community and Quercus mongolica-Abies nephrolepis community by phytosociological method. Quercus mongolica-Carpinus cordata community was subdivided into Acer mandshuricum subcommunity and typical subcommunity. 2. According to the classification of TWINSPAN, it was categorized into five groups, such as Quercus mongolica-Acer mandshuricum community, Quercus mongolica-Carpinus cordata community, Quercus mongolica-Acer pseudosieboldianum community, Quercus mongolica-Lindera obtusiloba community, and Quercus mongolica-Abies nephrolepis community. 3. Since the results of phytosociological community classification, which identify five groups of the community, were consistent with that of TWINSPAN, it proved that these two methods could be complement when one do a community classification.

This study was launched in order to collect basic data such as emergent species, a succession trend based on the actual vegetation at the ridge from Haneoryoung to Daetjae, thereby designating 46 quadrats($10m{\times}10m:100m^2$). As a result of classification by TWINSPAN, the plant community was categorized into eight different communities, such as Pinus densiflora-Quercus mongolica-Fraxinus rhynchophylla, P. densiflora-Q. mongolica, Ulmus davidiana var. japonica, Q. mongolica-Deciduous Broad-leaved, Q. mongolica, Q. mongolica-Betula davurica, Q. mongolica-F. sieboldiana, and Larix kaempferi. An analyzation of each communities indicated that P. densiflora dominant community will change into a Q. mongolica dominant community if there are no outside artificial disturbances. U. davidiana var. japonica community maintains its present condition, because it doesn't appear to be a competitive species. In the case of Q. mongolica dominant community, if nothing comes in a competitive species against Q. monglica, it is possible to succeed to a muture stand. These communities with competitive species such as F. rhynchophylla, B. davurica that do not emerge at a canopy layer will gradually progress to the Deciduous Broad-leaved community. With regard to the species diversity index per unit ($400m^2$), succession processing communities (P. densiflora: 1.0477~1.1283) tend to be higher than succession-processed communities (Q. mongolica dominant: 0.6446~0.9424).

본 연구는 계룡산국립공원 내의 군산보호구역의 산림식생을 대상으로 식물사회확적 방법으로 산림군락을 분류하고, 각 군락과 입지환경과의 상관관계를 분석하여 계룡산국립공원에 필요한 기초자료를 제공하고자 조사하였다. 계룡산 군산보호구역 내 총 94개 조사구를 분석한 결과, 식물군락은 졸참나무군락(Quercus serra-ta community)과 신갈나무군락(Quercus mongolica community)으로 구분되었다. 졸참나무군락은 해발고가 낮고 경사가 완만한 지역에, 신갈나무군락은 해발고가 높고 경사가 급한 지역에 분포하였다. 졸참나무군락은 하위군락인 때죽나무아군락(Styrax japonica subcommunity)과 소나무아군락(Pinus densiflora subcom-munity)으로 구분되었으며, 신갈나무군락은 하위군락으로 전형아군락(typical subcommunity)과 철쭉꽃아군락(Rhodoendron schlippenbachii scbcommunity)으로 구분되었다.

Forest vegetation of Choksangsan area in the Deogyusan National Park is classified into mountain forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, valley forest, coniferous forest, afforestation and other vegetation. Including 103 communities of mountain forest vegetation and 8 communities of other vegetation, the total of 111 communities were researched; the mountain forest vegetation classified by physiognomy classification are 36 communities deciduous broad-leaved forest, 26 communities of valley forest, 10 communities of coniferous forests, 31 plantation and 8 other vegetation. As for the distribution rate for surveyed main communities, Quercus mongolica, Quercus variabilis communities account for 65.96 percent of deciduous broad-leaved forest, Fraxinus mandshurica community takes up 22.50 percent of mountain valley forest, Pinus densiflora community holds 63.27 percent of mountain coniferous forest holds. In conclusion, minority species consisting of Quercus mongolica, Fraxinus mandshurica, Quercus serrata, Pinus densiflora, and Quercus variabilis are distributed as dominant species of the uppermost part in a forest vegetation of Choksangsan in Deogyusan National Park. In addition, because of vegetation succession and climate factors, numerous colonies formed by the two species are expected to be replaced by Quercus mongolica, Carpinus laxiflora and Fraxinus mandshurica which are climax species in the area.

This study was carried out to classify forest vegetation community of Dodeokbong and Baekwunbong in Gyeryongsan. Employing the releve method of Dierssen, 89 plots were sampled. Forest community was classified into Quercus mongolica community, Quercus serrata community, Quercus variabitis community, Pinus densiflora community, Carpinus laxiflora community, and Pinus rigida-Pinus thunbergii community. Quereus mongolica community was found in high altitude and steep area, Quercus serrata community in relatively low altitude and steep slope area, and Quercus variabilis in southern arid and low area compared with Quercus mongolica community. Pinus densiflora community is present in relatively high altitude and narrow arid ridge area. And, Carpinus laxiflora community is mainly distributed in southern valley area. Pinus rigida-Pinus thunbergii community is planted community.

This study examined the vegetation structure in the ridge of the Hannamgeumbuk-Jeongmaek and Geumbuk-Jeongmaek by selecting 7 sites(2 sites at Hannamgeumbuk-Jeongmaek and 5 sites at Geumbuk-Jeongmaek) in consideration of the environmental conditions and artificial influences and conducting the vegetation survey in the selected sites. The community classification based on TWINSPAN categorized the vegetation at Hannamgeumbuk-Jeongmaek into 8 groups: Quercus variabilis-Q. acutissima community, Pinus densiflora-Q. mongolica community, Pinus densiflora community, P. densiflora-Q. mongolica-Q. variabilis community, P. densiflora-Deciduous oaks community, P. koraiensis community, Q. mongolica-Q. variabilis community, and Larix kaempferi-P. koraiensis community. It also categorized the vegetation at Geumbuk-Jeongmaek into 9 groups: Quercus variabilis community, Deciduous broad-leaved community, Q. mongolica community, Pinus densiflora-Q. mongolica-Q. variabilis community, Q. acutissima community, P. densiflora-Q. acutissima-Q. variabilis community, P. densiflora-Q. mongolica-P. rigida community, P. densiflora-P. thunbergii-Deciduous oaks community, and P. koraiensis community. Two species, Quercus mongolica and Pinus densiflora, which are widely distributed in the ridges of the Jeongmaeks and Baekdudaegan in South Korea, were dominant in many of the surveyed sites. The appearance of planted Castanea crenata in some plots, although not in high population, suggests human intervention in most regions of the Hannamgeumbuk-Jeongmaek and Geumbuk-Jeongmaek in the past. The Gayasan area, which is part of the Geumbuk-Jeongmaek and where the maritime climate and continental climate overlap, showed Pinus thunbergii, reflecting the local climate characteristics.
