This study was carried out to analyze vegetation and soil characteristic, and ordination of Stewartia koreana community. The Stewartia koreana community was classified into Acer mono subcommunity, Pinus densiflora subcommunity, Sapium japonicum subcommunity, and Stewartia koreana typical subcommunity. In the study sites, soil organic matter, nitrogen, available phosphorous, exchangeable K, exchangeable Ca, exchangeable Mg concentration, cation exchange capacity, and soil pH were ranged from 14.31~34.27%, 0.33~0.77%, 7.83~22.88(mg/kg), 0.23~1.07(me/100 g), 0.29~2.93(me/100 g), 0.33~1.49(me/100 g), 10.47~22.48(me/100 g), and 4.65~4.96, respectively. The area of the Acer mono subcommunity, found in highlands, showed that contained the highest organic substances, nitrogen, available phosphorous, and cation exchangeable capacity concentration among the communities. The low elevation regions where the Pinus densiflor subcommunity is formed, showed the lowest concentrations of exchangeable Ca, and Mg.

This study was carried out to analyze the vegetation properties, soil characteristics, and ordination of Stewartia koreana community of Mt. Jirisan in Korea. The S. koreana community was classified into S. koreana-Quercus mongolica serrata community, S. koreana-Quercus mongolica community, and Typical community. In specific, S. koreana-Q. serrata community was classified into two subgroups such as Carpinus laxiflora subcommunity and typical subcommunity. The S. koreana community was found out to be located at an elevation of 409m to 1,604m. The Results of importance value on the S. koreana community consisted of the following in order: 75.47% of S. koreana, the highest, 21.83% of Q. serrata, 18.65% of Q. mongolica, 18.19% of Acer pseudosieboldianum, 10.56% of Rhododendron schlippenbachii, 10.36% of Styrax japonicus. In the targeted study sites, soil organic matter, total nitrogen, available phosphate, exchangeable potassium, soil moisture and soil pH were 3.15~39.1%, 0.37~11.7%, 0.9~45.4mg/kg, $0.09{\sim}1.48cmol^+/kg$, 19.28~55.47% and 4.08~5.65, respectively. The results of the correlation between communities and soil conditions of S. koreana community by DCCA ordination method are as follows: S. koreana-Q. serrata community was found in the highest elevation and followed in order S. koreana typical community, S. koreana-Q. serrata typical subcommunity, and C. laxiflora subcommunity.

The study was carried out to investigate the distribution and composition of community of Stewartia koreana in Temple Huibang and Mt. Sogri. The results obtained were as follows: 1. Within the forest floor cover species of the Temple Huibang forest, higher importance value were observed as Calamagrostis arundinacea. Sasa borealis. Lindera erythrocarpa and Lindera obtusiloba 2. In the forest floor cover species of Mt. Sogri forest, higher importance value were observed as Sasa borealis and Acer pseudo-sieboldianum var. koreanum 3. Within the floor cover species under Stewartia koreana forest, higher importance value were observed as Sasa borealis. Acer pseudo- sieboldianum var. koreanum and Calamagrostis arundinacea 4. Under shrub layer of Stewartia koreana stands, 73% of Sasa borealis and Calamagrostis arundinacea in Temple Huibang and 93% of Sasa borealis in Mt. Sogri were counted respectively as dominant species. Therefore, it might be necessary to control such dominant undergrowing species for natural reproduction of Stewartia koreana 5. In the Temple Huibang sites, by 700m Sasa borealis and 800m Calamagrostis arundinacea were grown as dominant species.

To investigate the structure of the forest community of Huibang valley in Sobaeksan National Park, twenty five plots were set up and surveyed. According to the analysis of classification by DCA community divided 4 groups. The divided groups are Pinus densiflora community, Q. mongolica -P. densiflora community. Q. mongolica-Stewartia koreana-Carpinus laxiflora community, and Q. mongolica- Acer pseudosieboldianum community. In the analysis by ordination, CCA which points out the relationship among the environmental variables, species and plots indicated primary step of secondary succession. The successional trends of both techniques. seem to be from P. densiflora through Q. mongolica, Q. serrate to C. laxiflora(or S. koreana) in canopy layer below an altitude of 800 meters, and from Rhododendron mucronulaltum. Rh. schlippenbachli. Rhus trichocarpa through Styrax obassia. Lindera obtusiloba to Magnolia sieboldii, Corylus sieboldiana in subtree and shrub layer. The positive correlation between the stand ordination scores .and soil moisture and soil humus were calculated.

To elucidate the actual vegetation of Nature Ecology Conservation area in Mt. Chiri, forest communities were classified phytosoclologically by species composition and phsiognomy. There included 13 forests ranging from temperate-cool zone to sub-cold zone in the surveyed area. Actual vegetation map was drawn on the basis of classified forest communities. The forest communities classified in the area were summarized as follows ; 1. Querus serrata community 2. Carpinus laxiflora community 3. Q. serrata-C. laxiflora community 4. Stewartia koreana community 5. Acer mono community 6. Carpinus cordata community 7. Fraxinus mandshurica community 8. Carpinus tschonoskii community 9. Pinus densiflora community 10. Querus mongolica Community 1) Rhododendron schlippenachii subcommunity 2) Lenedeza maximowiczii subcommunity 11. Abies nephrolepis community 12. Abies koreana community 1) Querus mongolica subcommunity 2) Pinus koraienis subcommunity 13. Rhododendron schlippenbachii community Among above forest communities, Querus serrata community distributed from 700m to 1,000m in the ridges, Carpinus laxiflora community in the valleys, Quercus mongolica community from 1,000m to 1,400m, and Abies koreana community and Abies nephrolepis community from 1,400m to 1,700m.

Mt. Kumjeong is located in south-eastern part of the Korean Peninsular($129^{\circ}$01' to $129^{\circ}$05' E, $35^{\circ}$03' to $35^{\circ}$17' N) and the altitude of the summit is 802 meter. In order to find out the vegetation units which made it possible to classify subtropical forest and south-temperate forest, Mt. Kumjeong (which is located in a border of between subtropical forest and south-temperate forest) was selected as a study area. The primary result of actual vegetation analysis in Mt. Kumjeong based upon the vegetation community analysis methods by the ZM-school, and the relationships between vegetation community and two parameters(altitude, topography) analyzed by using coincidence analysis method were summarized as followings. 1. Based upon analytic methods of the vegetation community by the ZM-schools, the primary analytic result of the analysis of vegetation community in Mt. Kumjeong was divided into 10 communities, 9 groups, 2 subgroups. 2. Eurya japonica group of Pinus densiflora community out of 16 vegetation units was thought as a indicator vegetation group which made it possible to border subtropical forest and south-temperate forest. 3. Natural regeneration of Stewartia koreana group was thought to be difficult because seedling and sapling was rarely showed, 4. In relationship between vegetation units and altitude, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community, Pinus thunbergii community mainly distributed below altitude 500 meter, and Quercus mongolica community, Typical group of Pinus densiflora community, Quercus dentata community, Carpinus coreana community, Quercus acutissima community mainly distributed above altitude 500 meter. 5. In relationship between vegetation units and topography, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community distributed below middle slope, Quercus mongolica community, Typical group of Pinus densifiora community, Quercus dentata community, Carpinus coreana community, Pinus thunbergii community Quercus acutissima communily clistributed above midclle slope.
