The objective of this study was to analyze characters of the vegetation structure, vegetation-environment relationships of Kyeryongsan forest community. Fifty plots were sampled in the valley forest of Donghaksa, Gabsa, Sanghasinri and Shinwonsa regions in Kyeryongsan. Field survey was carried out in August of 1999 to examine a vegetation type and measure a diameter. The classification by TWINSPAN, the DCCA ordination, and structure of stand were used to analyze data. The results of this study are as follows : 1. With the classification by TWINSPAN, the community was categorized into four groups, such as Carpinus laxiflora, Quercus variabilis-Quercus serrata, Zelkova serrata-Celtis jessoensis and Carpinus cordata communities. 2. The dominant species in Carpinus laxiflora community were Carpinus laxiflora, Quercus variabilis, Quercus serrata, Pinus densiflora and Styrax japonica. The dominant species in Quercus variabilis-Quercus serrata community were Quercus variabilis, Quercus serrata, Styrax japonica, Castanea crenata and Platycarya strobilacea. The dominant species in Zelkova serrata-Celtic jessoensis community were Quercus serrata, Castanea crenata, Lindera erythrocarpa, Zelkova serrata and Styrax japonica. The dominant species in Carpinus cordata community were Carpinus cordata, Carpinus laxiflora, Sapium japonicum, Cornus controversa and Zelkova serrata. 3. The results of the correlation between Kyeryongsan valley forest community and environmental factors by DCCA ordination method are as follows; The Carpinus laxiflora community was found in low elevation and steep slope area. The Quercus variabilis-Quercus serrata community was found in low elevation and lower slope area. The Zelkova serrata-Celtis jessoensis community was found in high elevation and lower slope area. The Carpinus cordata community was found in high elevation and midium slope area.

The present paper deals with a research of life form and vegetation of the plants extant in the habitat of endangered Parnassius bremeri in Uiseong, Gyeongsangbuk-do with a view to restore their habitat and create substitute habitats. The research found that there are a total of 130 vascular plants including 47 families, 96 genera, 113 species, 1 subspecies and 16 varieties. In terms of their life form, hemicryptophytes (H) is the majority of dormancy form with 41 species or 31.54%, while $R_5$ is majority of radicoid form with 72 species or 55.38%, gravitational disseminule form ($D_4$) is majority among the disseminule forms with 68 species or 52.31% and erect type (e) is majority of growth form with 57 species or 43.85%. Major constituents of the habitat are Sedum kamtschaticum, Selaginella tamariscina, Orostachys japonica, Arundinella hirta, Cymbopogon tortilis var. goeringii, Themeda triandra var. japonica, Carex humilis, Indigofera kirilowii, Imperata cylindrica var. koenigii, Festuca ovina, Artemisia capillaris, etc., all of species which are in the initial stage of succession and show simultaneously features characteristic of vegetation on the rock. In the habitat 1. Sedum kamtschaticum- Selaginella tamariscina community and Pinus densiflora community are distributed whereas, in the habitat 2. Sedum kamtschaticum-Selaginella tamariscina community, Sedum kamtschaticum-Carex humilis community, Sedum kamtschaticum-Cymbopogon tortilis var. goeringii community and Sedum kamtschaticum-Imperata cylindrica var. koenigii community are growing and in the habitat 3. Sedum kamtschaticum-Selaginella tamariscina community, Selaginella tamariscina community, Sedum kamtschaticum-Indigofera kirilowii community and Quercus acutissima community are seen distributed there, too. Typical of food plants growing in the habitat is Sedum kamtschaticum, found mostly in the rocky area and its surroundings. Absorption plants are those that usually bloom in the season when imagoes emerge. From the research, it becomes evident that the blooming season of Sedum kamtschaticum, obviously a food plant, corresponds exactly to the emergence timing of imagoes. Cirsium japonicum var. ussuriense, Rosa multiflora, Erigeron annuus, Spiraea prunifolia var. simpliciflora are found to belong to these plants.

The purpose of this study is to investigate the structure of vegetation dominated by deciduous broad-leaved trees at the Beomeosa(Temple) Valley of Mt. Kumjungsan in Busan. To this end, 28 plots were set up and surveyed. The result analyzed by TWINSPAN, one of the classification technique, showed that the communities were divided into six groups which are Carpinus tschonoskii-Deciduous broad-leaved forest community(I), Quercus serrata-C. tschonoskii community(II), C. tschonoskii-Q.s serrata-Pinus densiflora community(III), C. tschonoskii-Quercus serrata-Q. mongolica communtiy(IV), Q. serrata-Deciduous broadleaved forest community(V) and Chamaecyparis obtusa-C. tschonoskii community (VI). Species diversity ranged from 0.3832 to 0.0450. The lowest diversity was Chamaecyparis obtusa community(VI) but the highest was Carpinus tschonoskii-Deciduous broad-leaved forest community(I) and Q. serrata-Deciduous broadleaved forest community(V). The average number of species was 6.8${\pm}$3.2 in the unit area(100$m^2$). Carpinus tschonoskii community at the Beomeosa Valley of Mt. Geumjeongsan was a climatic climax forest having a value to preserve, so a continuous management will be needed.

To study the changes of soil and vegetational composition of Pinus densiflora community by campsite impact of its users, located in Kumo Mountain Provincial Park, the South part of Korea, three sites were selected according to the density of users. The heavy-use sites in this study has changed in the following ways. (1) The concentration of total nitrogen, available phosphate and Ca ion have decreased greatly. (2) From 68 to 73 percent of the undergrowth vegetation has been removed from the $2.000m^2$ camp area, leaving a sparse vegetation cover quite dissimilar in composition to nonuse campsite. (3) The soil hardness was $38.9kg/cm^2$ in heavyuse site and $1.76kg/cm^2$ in nonuse site. (4) The tolerant trees to campsite impact is Acer palmatum, Stephanandra incisa, Rhus trichocarpa, Rubus crataegifolitus and Parthenocissus tricuspidata. (5) Species diversity decreased to a degree at the heavy-use site. Similarity index was 25.38% between the heavy-use and nonuse site.

The forest vegetation of Juwangsan National Park, which is famous for its towering scenic valleys, was syntaxonomically described. The study adopted the $Z{\ddot{u}}rich$-Montpellier School's method emphasizing a matching between species composition and habitat conditions. A combined cover degree and the r-NCD (relative net contribution degree) were used to determine a performance of 265 plant species listed-up in a total of 52 phytosociological $relev{\acute{e}}s$. Nine plant communities were classified through a series of table manipulations, and their distribution and actual homotoneity($H_{act}$) were analyzed. Syntaxa described were Carex gifuensis-Quercus mongolica community, Athyrium yokoscense-Quercus mongolica communiy, Arisaema amurense-Quercus serrata community, Lespedeza maximowiczii var. tomentella-Quercus variabilis community, Tilia rufa-Quercus dentata community, Carex ciliatomarginata-Carpinus laxiflora community, Aristolochia manshuriensis-Zelkova serrata community, Onoclea orientalis-Fraxinus mandshurica community, and Carex humilis var. nana-Pinus densiflora community. A zonal distribution was reviewed and the altitude of about 700 m was the transition zone between the cool-temperate central montane zone (Lindero-Quercenion mongolicae region) and southern submontane zone (Callicarpo-Quercenion serratae region). Only 19 taxa were associated with r-NCD 10% or more, most of which were tree species occurring in the Lindero-Quercenion and some of which was a member of open forests. Species composition of forest vegetation was much less homogeneous, showing the lowest $H_{act}$. Nearly natural forests and/or secondary forests in the Juwangsan National Park were defined as a regional vegetation type, which reflects much stronger continental climate in the Daegu regional bioclimatic subdistrict, rhyolitic tuff predominant, and wildfire interference.

Forest vegetation of Birobong (1,563 m) in Odaesan National Park is classified into mountain forest vegetation and flatland forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, valley forest, coniferous forest, subalpine coniferous forest, subalpine broad-leaved forest, afforestation and etc., while riparian forest was found under the category of flatland forest vegetation. Including 196 communities of mountain forest vegetation, 1 community of flatland forest vegetation and 4 communities of other vegetation, the total of 201 communities were researched; the distributed colonies classified by physiognomy classification are 62 communities deciduous broad-leaved forest, 84 communities of valley forest, 15 communities of coniferous forests, 16 communities of subalpine coniferous forest, 3 communities of subalpine broad-leaved forest, 16 afforestation, 1 community of flatland forest and 4 other communities. As for the distribution rate for surveyed main communities, Quercus mongolica, Quercus variabilis, Tilia amurensis communities account for 37.08 percent of deciduous broad-leaved forest, Juglans mandshurica, Fraxinus mandshurica, Cornus controversa, Populus koreana community takes up 1.59 percent of mountain valley forest, Pinus densiflora community holds 6.65 percent of mountain coniferous forest holds. In conclusion, minority species consisting of Quercus mongolica, Quercus variabilis, Tilia amurensis, Juglans mandshurica, Fraxinus mandshurica, Cornus controversa, Populus koreana, Pinus densiflora are distributed as dominant species of the uppermost part in a forest vegetation of Birobong in Odaesan 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, Tilia amurensis and Juglans mandshurica which are climax species in the area. However, the distribution rate of deciduous broad-leaved forest seems to increase gradually due to global warming and artificial disturbance.

This study aims at classifying and interpreting on the forest vegetation located in the whole area of Mt. Boryeonsan in Noeunmyeon, Chungju city, Chungcheongbuk Province, Korea using the methodology of the ZM school of phytosociology. The forest vegetation was classified into one Larix leptolepis afforestation, five secondary communities including Qurecus acutissima community, Pinus densiflora community, Quercus aliena community, Quercus serrata community, Quercus variabilis community and one association, Ainsliaeo-Quercetum mongolicae Song et al. 1999(Rhododendro schlippenbachii-Quercion mongolicae, Aceri pseudosieboldiani-Quercetalia mongolicae, Quercetea mongolicae). The research expatiated on the relationship between species composition of the forest communities and the environmental conditions, such as human interference, altitude, slope, topography and chemical properties of soil, and also analyzed the life form by each community. As a result, the Ainsliaeo-Quercetum mongolicae was judged as the most stable community among the forest communities identified here. On the other hand, a division of cluster analysis based on the dominance of the component species, appeared similar to the community units classified phytosociologically. Thus, it is inferred that the survey area will be dominated by the potential natural vegetation, Ainsliaeo-Quercetum mongolicae finally, if progressive succession is advanced continuously.

This study aims to understand the characteristics of dangsan forests and rural community forests (RCF), and seek for a landscape management scheme. Dangsan forests and RCF have been maintained by local residents since hundreds of years ago. However, many of them have been disturbed. The case sites were derived from the twenty villages previous investigated where dangsan forests and RCF's remainrd. The two sites were remodelled to restore what have been degraded. Hanbam village has maintained its dangsan forest with good management practices, whereas the dangsan forest and RCF of Goiran village showed relatively poor management. The size of dangsan forest at hanbam village was 13,784$m^2$, and major tree species was Pinus densiflora. In total, 151 trees with more than 30cm in DBH were standing on the site. As a cultural activity, the dangsan festival have been held in January $5^{th}$ by lunar calendar to the 2005 at the Jindongdan, a dangsan tree made of stone. The RCF of Hanbam village has disappeared due to the event of landslide in 1930, which needs to be restored. Goiran village has a dangsan forest and a RCF. The forests in Goiran village revealed many problems due to bad management practice. The prototype of the dangsan forest was deteriorated by introduced Prunus serrulata and the facilities for physical training. A systematic management scheme for dangsan forests and RCF's should be established with a close partnership among local residents, experts, and local government.

This research aims at having a grip on the actual condition of vegetation distribution Byeonsanbando National Park and to propose a survey and drawing criteria for vegetation map. Thus, this research conducted a survey of the vegetation distribution on Byeonsanbando National Park through review of the literatures on vegetation surveys on the National Parks in the past and at the present and preparing criteria for survey and drawing of vegetation. The actual vegetation of Bye on san ban do National Park was classified into eight plant communities and other land; the Substitution forest, or natural forest was classified into four plant communities including Quercus variabilis community, deciduous forest, Pinus densiflora community, and mixed forest while afforested land was classified into four forest types: P. rigida forest, P. thunbergii forest, P. rigida forest, P. rigitaeda forest, P. rigida - thunbergii forest, etc. The area belonging to grade 7 in Nature Degree was found to be the largest, covering 69.1% in Byeonsanbando National Park while the area belonging to grade 9 was very rare, covering 0.36%. Thus, it is suggested that criteria for survey and drawing map needed for the systematic survey and management of vegetation in National Parks.
