The moor vegetation of Daeryong-po on Mt. Daeam, east-central Korea was investigated in July 26th-29th, 1989, It was classified into I community group, 4 communities and 5 subcommunities; Sanguisorba tenuifolia var. alba community group, Sphagnum palustre community. Typical subcommunity, Eleocharis mamillata var. cyclocarpa subcommunity, Carex canescense subcommunity, Carex dispalata community, Spiraea salicifolia community, Geranium eriiostemon var. megalanthum community, Arundinella hirta-Phragmites communis subcommunity, Angelica purpuraefolia subcommunity. According to this classification, the actual vegetation map was made. The distribution of vegetation in this moor was divided characteristically into two areas. One was a typical oligotrophic area characterized by S. palustre community. The other was an area having mesotrophic or eutrophic conditions where its original state was disturbed by inflow of soil particles and removal of peat. It this disturbed area, C. dispalata, S. sibiricus, G. eriostemon var. megalanthum, were invaded.

This study aim that definite the relationship between coastal environment and different sand bar communities, as well as to analyze their spatial distribution of barrier island in the Nakdong river estuary. Survey method follow by Braun-Blanquet(1965) and there a total of 118 relev$\acute{e}$'s were undertaken. Definition of the relationships between species and environmental variables with Canonical Correlation Analysis(CCoA) and that to applied these relev$\acute{e}$'s with the RIM(Kim and Kim, 2006) program and that to classification used the SYN-TAX 2000 program(Podani 1979). On the basis of about 118 phytosociological releve's, the vegetation of xeric and hydric type was arranged in twelve plant communities: Xeric type-Pinus thunbergii community,Vitex rotundifolia community, Carex pumila community, Imperata cylindrica var. koenigii community, Miscanthus sacchariflorus community and Calystegia soldanella community, Hydric type-Salix dependens-Calamagrostis epigeios community, Calamagrostis epigeios-Phragmites communis community, Phragmites communis-Ischaemum aristatum community, Phragmites communis community, Scirpus planiculmis community and Suaeda glauca-S. japonica community.These plant communities represents sand dune vegetation and salt marsh vegetation. Widely distributing types in the actual vegetation map were sea club-rush community, reed community in salt marsh, and dry grassland. The edge in the coastal sand bars has zonation that almost distribution by the reed community in salt marsh. But outside of it were distributed sea club-rush community. Dry grassland type distributes higher zone of the center in coastal sand bars. Respectively, the coastal sand dune and salt marsh vegetation types were distributed ocean and inland on the frontier of it.

Phragmitetea Tx. et Prsg. 1942 (Triglochietum maritimae assoc. nov., Carcetum scabrifoliae Miyawaki et Ohba 1969, phragmites communis community, Pyaceluretum latifolii Miyawaki et Okuda 1972, Scirpus fluviatilis community) E. Salsoletea komarovil Ohba, Miyawaki et Tx. 1973(Salsola komarovi community) F. Glehnietea littoralis ohba, Miyawaki et Tx. 1973(Caricetum pumilae assoc. nov., Meserschmidia sibirica community, Lysimachia mauri-tiana community Ishaemum anthephoroides community, Elymus mollis commuity, carex kobomugi community, Ixeris repens community) G. Viticetea rotundifoliae Ohba, Miyawaki et Tx. 1973 (Imperato cylindricae-Viticetum rotundifoliae ohba, Miyawaki ex Tx. 1973) and Opuntia ficus-indica var. saboten community. Among the soil properties, water potential seems to be one fo the most important factor on the distribution of the coastal plant community and it might be highly affected by water content in sand and salinity in low marsh.

The study was carried out to classify forest vegetation structure of Mt. Guryong which is located in Bonghwa-gun, Gyeongsangbuk-do province. 72 plots(quadrat) were investigated from July to August in 2010 using phytosociological analysis methodology of Z-M schools. The forest vegetation of the study area was classified as Quercus mongolica community group that was further divided into 5 communities; Pinus densiflora for. erecta community, Acer mono community, Quercus mongolica typical community, Larix leptolepis community and Pinus koraiensis community. Pinus densiflora for. erecta community was subdivided into Quercus variabilis group and Pinus densiflora for. erecta typical group. Acer mono community was also subdivided into Prunus maackii group and Deutzia glabrata group. The vegetation of the study areas could be described as 1 community group, 5 communities and 4 groups and 7 units in total. Classified vegetation units were highly correlated with altitude and topography. It was considered that forest tending operations for maintaining need to be continuously practiced for Quercus spp. with highly relative dominance value in the Pinus densiflora for. erecta community (vegetation units 1, 2).

This study was conducted to suggest vegetation management plan for Gugok landscape maintenance and improvement by deducing the vegetation landscape factors inherent in Yongha Gugok and understanding vegetation structure through the investigate of existing vegetation and plant community structure of Yongha valley in Woraksan National Park. There were broad and flat rocks, natural layered stones, clear water, light stones, stream, valleys, waterfalls, Pinus densiflora and Acer pseudosieboldianum as a result of deducing natural factors on poetry. There were P. densiflora and A. pseudosieboldianum appeared as one of main vegetation landscape elements. The actual vegetation analysis results were as followed. The natural vegetation occupied 67.5% and it was classified as P. densiflora community, Quercus variabilis community, Q. variabilis-P. densiflora community, Q. variabilis-Q. serrata community, Q. serrata community, Q. mongolica community, Q. mongolica-P. densiflora community, Deciduous broad-leaved tree community. The artificial vegetation(18.7%) was classified as Q. serrata community-Larix kaempferi community, Q. mongolica- Castanea crenata community, L. kaempferi community, L. kaempferi-C. crenata community, fruticeta, L. kaempferi-Q. mongolica community. The grassland area(2.0%) was classified as Miscanthus sinensis community, Phragmites communis community, and other areas were classified as landscape tree planting area, farm, orchard, residential area. The representative vegetation were P. densiflora community, Q. variabilis-Q. serrata community, L. kaempferi community, Deciduous broad-leaved tree community in Yongha Gugok. The species diversity index of Shannon was 0.6274~0.9908 on the whole. Yongha Gugok, as a symbol of succession on confucianism and reverence for nature, should be preserved natural valley landscape being clean and wijungchuksa at the end of Joseon Dynasty and Japanese Colonial era. In this historical and cultural Gugok, vegetation landscape management plan is needed to landscape maintenance with P. densiflora community, density control with L. kaempferi community. And it is considered when natural disasters and artificial damages happened, P. densiflora-oriented vegetation restoration plan should be applied in order to restore.

This paper is to contribute for management and restoration as a basic study of vegetation structure in Aemirang Hill, Nakdongjeongmaek. To verify the characteristics of vegetation structure, we set up 25 plots($100m^2$). The result of community analysis was used by TWINSPAN classification. The communities were classified 7 types i.e. Quercus variabilis community, Quercus mongolica community, Pinus densiflora community, Pinus densiflora-Quercus mongolica community, Q. mongolica-Quercus variabilis community, Quercus mongolica-Betula davurica community, Larix leptolepis community. Pinus densiflora community and Pinus densiflora-Quercus mongolica community are progressively transforming a Quercus mongolica community that is called Pinus densiflora next succession stage. Whereas the communities that has dominant Quercus variabilis and Quercus mongolica did not appear a next generation succession tree such as Carpinus laxiflora, Carpinus cordata in the under story and shrub layer. Therefore, Aemirang Hill's ecological succession was to maintain the status condition. Aemirang Hill's diversity index is 0.5738 to 0.8906. It were analyzed that diversity index was lower than other places.

The aim of this study was to investigate the vegetation types of Minarimot, in Jeju Islands. The vegetation types were classified by the Z-M school method and cluster analysis. The vegetation in Minarimot was classified into 6 communities and 2 subcommunities: Persicaria thunbergii-Isachne globosa community (vegetation type: A), Scirpus tribangulatus-Eleocharis manillata var. cyclocarpa community (B) (Aneilema keisak subcommunity (B-1) and Caldesia parnassifolia-Potamogeton distinctus subcommunity (B-2)), Eleocharis kuroguwai community (C), Phragmites communis community (D), Scirpus tabernaemontani community(E) and Typha orientalis community (F). These communities were grouped into three main categories according to cluster analysis. The community (A) established at the edge of the wetland which has the driest condition was distinguished as Group I, while the community (B) emerged in the submerged zone was distinguished as Group III. The Group II was designated as the communities (C, D, E, F) between Group I and III, whose communities were occasionally submerged. The result of principal coordinate analysis (PCoA) appeared that the different vegetation established along the wetland were depending on water environment such as water depth and the period submerged.
