This study was conducted to compare and analyze forest vegetation distributed in Geumosanseong-inside in Geumosan Provincial Park from 2017.10 to 2019.6. The vegetation structure was classified by the phytosociological method and TWINSPAN and the correlation between the community structure and the environmental factors was analyzed using DCCA ordination analydsis. The vegetation structures are Quercus mongolica, Fraxinus mandshurica, Q. acutissima, Larix leptolepis, Prunus padus and Morus alba community by the phytosociological method and 16 communities under TWINSPAN. The importance value of Q. mongolica(64.5) was the highest, and followed by F. mandshurica, L. leptolepis, Acer pseudosieboldianum, M. alba, P. padus, Q. acutissima, Sorbus alnifolia, P. serrulata var. pubescens, F. sieboldiana, Rhododendron schlippenbachii and Castanea crenata which is consistent with species having the dominance status by analysis of the vegetation structure. As the results of DBH analysis for taxon with high importance values, Q. mongolica and M. alba represented normal distribution, and thus, the dominance status of these species is likely to continue. L. leptolepis will maintain the dominance status due to high density of large individuals as compared with species above medium size. However, it will decrease because of high mortality after increase in age class. F. mandshurica and P. padus continue to show dominance status due to high density of young individuals as compared with species above medium size. Q. acutissima have high density of individuals above intermediate size and low density of young individuals, and thus, will maintain the dominance status. A. pseudosieboldianum, F. sieboldiana and R.schlippenbachii which are arborescent will present continuously high dominance status because of high density of young individuals. Soil analysis shows that whereas pH, Ca²⁺ and Mg²⁺ in the research area were lower than the average values of overall forest soil and O.M, T-N, C.E.C and P₂O₅ were higher. We expected that these results were due to agricultures until 50 years ago in Geumosanseong-inside. As a result of DCCA ordination analysis using eleven environmental factors and communities classified by the phytosociological method analysis showed that Q. mongolica was distributed in the environment with higher elevation and O.M and steep slope, and lower P₂O₅, Mg²⁺ and Ca²⁺. In contrast to F. mandshurica, Q. acutissima was distributed in higher K⁺ and lower pH. L. leptolepsis was distributed in various environment.

The phytosociological study was carried out to investigate the Corylopsis gotoana var. coreana community structural characteristics and soil environment of Mt. Baegun in Pochen. The vegetation data of total 9 relev$\acute{e}$s were analyzed by the Z$\ddot{u}$rich-Montpellier school's method. Three communities of Mt. Baegun were recognized : Corylopsis gotoana var. coreana - Quercus mongolica community, Corylopsis gotoana var. coreana - Carpinus laxiflora community, Corylopsis gotoana var. coreana typical community. The reanalysis to Corylopsis gotoana var. coreana community structural characteristics in south area classified 8 communities by literature. PCA analysis of Corylopsis gotoana var. coreana community distributed in the middle and southern area showed that the Corylopsis gotoana var. coreana community of the Mt. Jiri in the southern area was highly correlated with the one of Mt. Baegun in the middle area.

The study was aimed to understand the ecological status of the Maebongsan urban forest in Cheongju-si through investigating the vegetation, soil characteristics, and soil microarthropods. Phytosociological analysis for twenty plots revealed that the plant communities were classified into Pinus rigida community, Robinia pseudoacacia community, Castanea crenata community, Quercus acutissima community, Pinus strobus community, Pinus koraiensis community, and Larix kaempferi community. The importance value showed that afforestation tree species like Castanea crenata, Robinia pseudoacacia, and Pinus rigida dominate the urban forest. DBH analysis indicated that although the plant communities seem to be under the succession to Quercus forest, the dominance of Castanea crenata and Robinia pseudoacacia might still persist for several more decades. The properties of soils from the plant communities showed that loamy sand and sandy loam in soil texture, low organic matters, and severe acidification. The abundance of soil microarthropods were not different among the plant communities except Castanea crenata community and Pinus koraiensis community. The two communities showed especially low abundance of collembola and acarina. Thus, we can say that Castanea crenata community and Pinus koraiensis community seem to have been influenced strongly by anthropogenic activities.

Vegetation structure of Seokseong fortress in Buyeo-Gun was investigated to suggest a desirable management proposal. Communities by phytosociological method were classified into Pinus rigida-Pinus densiflora community and Quercus variabilis community. The importance value of Pinus rigida, Pinus densiflora, Quercus variabilis, Pinus thunbergii, and Quercus acutissima were 127.06, 70.29, 69.63, 12.39 and 8.57. According to breast diameter analysis results, it is expected that the importance value of Pinus rigida, Pinus densiflora, and Quercus variabilis will be continuously increased. It should be prepared that vegetation management plan over the castle wall should be considered before the repair or restoration of castle wall. Vegetation management around castle wall should be carried out according to the mid or long-term plan and it would be needed to consider the gradual changes from planted Pinus rigida to the historical vegetation of Pinus densiflora.

This study was carried out to classify forest vegetation structure of the subalpine zone in Mt. Seorak (Daecheongbong 1,708 m) from June to August in 2005 with phytosociological analysis of ZM school. Samples were collected by 81 of releves more than 1,200 m of altitude. There were 14 of physiognomy stands in the study area. The results were summarized as follows. Vegetation of the area was characterized by Abies nephrolepis community group, which was classified into Rhododendron schlippenbachii community and Lonicera coerulea var. emphyl-localyx community. The former was divided into Acer truncatum group and Pinus koraiensis group (subdivided into Acer tschonoskii var. rubripes subgroup and Tilia taquetii subgroup) and the latter was into Pinus pumila group and Juniperus chinensis var. sargentii group. It consisted of 5 units of vegetation structure.

Vegetation structure of Jangtaesan Natural Recreation Forest in Daejeon City was investigated to suggest a preferable management plan. Vegetation survey was carried out with thirty plots. Adopting phytosociological method, plant communities were classified into twinfolds of natural and afforested area. A natural forest were composed of Quercus mongolica, Quercus variabilis, and Pinus densiflora community. Afforested area were with Metasequoia glyptostroboides, Larix leptolepis, Pinus koraiensis, and Castanea crenata community. The importance value of Quercus mongolica, Quercus variabilis, Pinus densiflora, and Quercus serrata in natural forest were 59.69%, 48.32%, 39.10%, 21.53%, respectively. According to diameter of breast hieght analysis results, it is expected that the occupancy of Quercus mongolica, Pinus densiflora, and Quercus variabilis would be continuously increased. Based on the findings of the study, management plan for natural forest and afforested area was recommended in line with the progress of natural ecology.
