To figure out the vegetation situation in the ridge of the Naknam-Jeongmaek, six intensive survey sites were selected considering environmental factors and human interferences, 132 quadrats (area $100m^2$) were installed to survey appearing species of trees and major environmental factors, and the characteristics of vegetation structures were analyzed. The surveyed plots were divided into six groups according to the analysis of classification by TWINSPAN; Quercus mongolica-Q. variabilis community, Pinus densiflora-Q. dentata community, Chamaecyparis obtusa community, Q. mongolica-P. densiflora community, P. densiflora-P. thunbergii community, P. koraiensis community, Rhododendron spp.-Lespedeza cyrtobotrya community. P. densiflora-Q. dentata community, Q. mongolica-P. densiflora community, and P. densiflora-P. thunbergii community are expected to be succeeded by deciduous oaks because the power of deciduous oaks is strong in their lower layer. C. obtusa community, P. densiflora community, and Rhododendron spp.-L.cyrtobotrya community are artificial forests that were artificially formed and are expected to be maintained in the current state for some time because the dominance value of planted species of trees is high. Most vegetations in Naknam-Jeongmaek were secondary forests or artificial forests formed for forest tree production and forestation for erosion control. In particular the top regions and hilly sections of the mountain were mostly dominated by deciduous oaks such as Q. mongolica, Q. variabilis showed some P. densiflora community competing with deciduous oaks. On the other hand, low sections and regions adjacent to the city showed severe artificial interference since exotic species such as P. thunbergiil, C. obtusa, P. koraiensis, and Rhododendron spp. were planted.

We have studied characteristics of community structure on the benthic macro-invertebrates at twelve selected sites in upstream, midstream and downstream of Paemsagol, Piagol, Chilseongol and Daeseonggol, major streams of Jirisan Mountain, for three years from April 2008 to September 2010. As a result, 2 phyla, 3 classes, 11 orders, 41 families, 119 species and 4,449 individuals of benthic macro-invertebrates have been collected and classified in this study. Among them EPT group (Ephemeroptera, Plecoptera, Trichoptera), commonly appearing taxa in clean stream ecosystem, was found most frequently. The highest species number of benthic macro-invertebrates were collected in 2008, the year with lower climatic influence including heavy rain. In almost all of survey sites 80% or over of EPT group were counted, and St. 1 scored highest rate of EPT group at 92.59%. Most dominant species was Ecdyonurus kibumensis at 12.83% of dominance index, and subdominant species was Goerodes KUb at 6.81% of dominance index. The investigation of the feeding function group indicated that gathering-collectors were dominant with 26 species and 1,334 individuals, while the number of filtering-collectors was lowest with 11 species and 230 individuals. This result represents that the feeding function group of Jirisan Mountain is mountainous stream-specific one. Both diversity index and richness index were lowest at the midstream of Chilseongol (St. 5), while the midstreams of Daeseonggol (St. 11) and Piagol (St. 8) were highest in diversity and richness indices respectively. The analyses of linear regression and correlation were performed in order to investigate and to predict the appearance aspect of EPT group by altitude. The results showed that the ratio of Plecopteran species number has increased by the elevation of the altitude at 0.05 significance level. Cluster analysis was also carried out for evaluating environmental similarities among survey sites. As a result, upper regions of Paemsagol (St. 1) and Piagol have clustered as most similar sites each other, while the midstream of Piagol (St. 8) has separated with lower similarity value than other sites in species composition.
This study aims to clarify the diversity and distribution characteristics of plant communities in four small mountain wetlands located in the high altitude area of Cheonchuk Mountain within the Wangpicheon Basin Ecological Landscape Conservation Area in Seomyeon, Uljin-gun, Gyeongsangbuk-do. A total of 26 vegetation data were collected according to the Z.-M. school's phytosociological vegetation survey method considering the homogeneity of habitat type and species composition. Four physiognomic vegetation types composed of 9 syntaxa was confirmed through vegetation classification according to dominant correlation and vegetation type classification considering species composition. The Iris ensata var. spontanea-Molinia arundinacea community is a dominant plant community representing the research area. After human use, vegetation is developing through natural transition in a homogeneous location left unattended, but the distribution of other plant communities was rarely observed due to the narrow wetland area. The microtopography and hydrological environment of each wetland were identified as key factors affecting the diversity and distribution of vegetation.

Rural areas dominates the country landscapes in size with less population and rich traditional heritages as well as natural landscapes. Rural community groves (RCG) and Dangsan groves have been established by community residents during a few hundred years, and most of them have been disturbed. Only a few RCGs and Dangsan groves remain for an extensive period with efforts from community residents. These remnant RCGs and Dangsan groves are highly evaluated representing Korean rural cultural landscapes. Sound understanding on the structure of the rural landscapes and their role on the rural community environment is required to provide an appropriate policy for managing rural landscapes. This study aims to understand the characteristics of RCGs and Dangsan groves in the cultural landscapes, to investigate policies and issues of the advanced countries on RCGs and Dangsan groves, and to overview domestic policies for rural landscapes. The study results showed that there is a close relationship between RCGs and main issues discussed in EU countries. Ministry of Agriculture & Forestry of Korea, Ministry of Environment and Rural Development Administration have to focus on the potential of RCGs and Dangsan groves for multi-functions of agricultural and rural areas, natural streams, rural amenity, direct subsidy for landscape preservation and rural tourism. Based on the findings, this study suggests that RCGs and Dangsan groves will provide benefits to develop rural-mountain-sea villages and to enhance country's landscapes as well as local landscapes.
This study has targeted Quercus acutissima forests in Korea and has classified the association between Quercus acutissima forests by using the phytosociological method. In addition, the correlation between each association, distribution, potential natural vegetation, and aspect of Quercus acutissima forest according to location have been analyzed to examine the characteristics of the Korean Quercus acutissima forests. Through factor analysis of DECORANA, it was revealed that Quercetum serrato-acutissimae forms in the basal zones of mountains, Quercetum mongolico-acutissimae is formed in the highlands, in the relatively high mountain area, and Carpino-Quercetum acutissimae is mainly distributed in valleys. However, this phenomenon is not very obvious, as each association structure is often mixed up. This result is caused by inhomogeneity of the Quercus acutissima forests, and most of it is distributed in basal zones or around farmlands where there are severe disturbance factors. The proposed potential natural vegetation of the Quercus acutissima forests in Korea is as follows; Quercetum serrato-acutissimae$\rightarrow$Quercus aliena-Quercus serrata community$\rightarrow$Quercus serrata community, Quercetum mongolico-acutissimae$\rightarrow$Quercus aliena-Quercus mongolica community$\rightarrow$Quercus mongolica community, Carpino-Quercetum acutissimae$\rightarrow$Quercus aliena-Carpinus laxiflora community$\rightarrow$Carpinus laxiflora community.

The purpose of this study is to analyze performance factors of the school and community libraries in its beginning, growth, development, and expansion to identify the assignment of the movement at the present stage. In this study, we performed interviews with those concerned with the school community and library movement and collected various relevant literature. The school and community libraries movement can be divided into five stages including beginning, growth, development, expansion, and turning point. Therefore performance and significance of school and community libraries shown in the history of the movement may be summarized as follows. First, school and community libraries were established mainly in areas isolated from cultural benefits, contributing to resolving problems such as a lack of public libraries and concentration of small libraries in certain areas. Second, the movement promoted the operation of school libraries by providing books for small-sized elementary schools in farming & fishing villages and mountain villages, libraries that were insufficient in books. Third, the movement utilized the minimal personnel, books, and spaces of school libraries to provide library services to community residents, securing permanence of library services, if nothing else. Fourth, school and community libraries played the role of local community-based libraries, intensifying the community spirit of residents and vitalizing communities.
Mt. Deogyusan, 1,614m in altitude, is located in the southwest of South Korea. Around Mt. Duckyu, many Korean endemic and rare plants are populated, so it is considered a very important biogeographical area where the temperature zones of northern and southern plants are crossed. Because it is the graceful figure of Mt. Duckyu, it is a common mountain where many tourists visit frequently. Continuous tourist's visit may cause a bad influence on vegetation around the climbing paths. Therefore, weed community around the climbing paths on Mt. Duckyu, where visitors exert a bad influence directly on its community by coming in and out, was surveyed phytosocialogically. Our surveys have been accomplished from July to August, 2003. Weed communities formed around the climbing paths on Mt. Duckyu were divided into several patterns and analysed. They have been divided into 8 communities and 4 subcommunities. Community A: Plantago asiatica community, A-a: Carex bostrychostigma subcommunity, A-b: Artemisia princeps var. orientalis subcommunity, B: Sasa borealis community, B-a: Carex siderosticta subcommunity, B-b: Veratrum parulum subcommunity, C: Rubus crataegifolius community, D: Hosta longipes community, E: Tripterygium regelii community, F: Miscanthus sinensis var. purpurascens community, G: Carex okamotoi community, H: Lespedeza maximowiczii community. The flora surveyed in these communities was constituted of 34 families, 83 genera, 12 varieties, and 92 species. Wild plants such as Plantago asiatica, Artemisia princeps var. orientalis, Rubus crataegifolius, Sasa borealis and Miscanthus sinensis var. purpurascens were mostly light loving plants and higher resistant plants against the stamping pressure.
The purpose of this study was to provide basic information and investigate a vegetation structure around Tohamsan (Mt.) Wetland. Actual vegetation map was made on the basis of watershed around that. Vegetation structure survey was carried out for 8 representative communities of actual vegetation which were Pinus densifrora community, Quercus variabilis community, Cornus controversa community, Q. serrata community, Q. mongolica-Q. serrata community, Salix koreensis community, Q. mongolica community, Q. variabilis-Q. mongolica-Q. serrata community. Tohamsan (Mt.) Wetland is located on 490m above sea level and the area of watershed was $236,272m^2$. Vegetation type were divided into 16 types, and the ratio of Q. mongolica community was 33.1% ($78,209.2m^2$). In order to turn out the structure of 8 representative communties, 32 plots were set up and unit area of plot was $100m^2$. The estimated age of forest is 30~50-years-old, and in the resutls of soil analysis, acidity was pH 4.89 and organic matter was 4.46%.
The purpose of this study is to investigate the developmental process of plant community during the secondary succession through the analysis of floristic composition, life form etcectra in burned site, and the structure of forest stand before forest fire occurrence was estimated by the method of anatomical wood identification for dead trees in burned site, Cheisuk-bong in Mt. Chiri of Korea. Plant community before forest fire occurrence was estimated the high mountain conifer stand of the last successional stage to consist of Pinus koraiensis(75%), Abies koreana(15%) and Picea jezoensis(10%), and Betula costata was survived only one species after forest fire occurrence. The total number of plant species in the investigated area was 19 families and 23 species that was identified. The dominate species in burned site were Festuca ovina and Arrhenatherum elatius, Carex humilis, Ligularia fischeri etcectra in the investigated area flora. The life form of plant in burned site was the erect from 47.8%, the tufted from 30.4%, the branched and the prostrate from was both 8.7%, It was assumed that dominant species in the burned sites were Gramineae (Festuca ovina, Arrhenatherum elatius), Carex humilis ${\rightarrow}$Sorbus commixta, Rhododendron schrippenbachii, Sambucus williamsii var. coreana, Tripterygium regelii ${\rightarrow}$Acer pseudo-sieboldianum var. koreanum, Betula costata, Quercus mongolica${\rightarrow}$Pinaceae forest(Pinus koraiensis, Abies koreana, Picea jezoznsis).

The purpose of this study is to identify the ecological characteristics and biological interactions between species of the abandoned rice paddy field in mountainous areas and to suggest a management strategy for stable food chain formation and biodiversity enhancement. The study site is located in Uldae wetland of Songchu district Bukhansan National Park, site characteristics and biological habitat characteristics were identified through site survey and literature survey. With regard to physical environment, among geographical features, the Uldae Wetland and the neighborhood inside the basin was a gently sloping area($5{\sim}15^{\circ}$). And 64.0% of basin faced the north. With regard to water environment, the Uldae Wetland was wetland of rainfed paddy field depending on precipitation and the system of stream flowing into the wetland from valley. According to the results of examining flora in plant ecology, in general, they were herbaceous wetland species. 88.6% of existing plants inside the Uldae Wetland basin was a forest in the mountain. And Quercus spp. community and Pinus densiflora community accounted for 64.6% of that, and was dominant. Except for that, Salix koreensis community was distributed. The existing vegetation of Uldae Wetland inhabited wetland species and terrestrialization indicator species, and it was thought that partial terrestrialization inside the Uldae Wetland was in progress after the discontinuation of paddy cultivation, such as the expansion of Salix koreensis distribution area. In the status of appearing faunae in the Uldae Wetland with regard to wildbirds of appearing principal species, The Uldae wetland was based on a abandoned rice paddy field various wildlife, and was a wildlife feeding, spawning, and resting place. The water environment was an important factor in maintaining the wetland living creatures function, habitat of waterbirds and benthic macroinvertebrates, amphibians and odonate are spawning ground and habitat, it was affecting the vegetation ecosystem based on wetlands. In order to maintain the diversity of wildlife, it was important to maintain smooth water supply and water level. A stable food chain will be formed and the Uldae wetland biodiversity will be abundant by establishing the relationship between the species of Uldae wetland, which is abandoned rice paddy field, and the habitat environment favored by species belonging to the ecosystem stepwise linkage. The ecological characteristics of the Uldae wetlands and the relation between the species were analyzed and the environmental conditions were reflected in the planning and management plan of Uldae wetland ecology.
