This study suggested a vegetation restoration plan for a coastal area where the ecosystem conservation fund return project, targeting the whole area of Dalmaji-gil, located in Haeundae, Busan. After distinguishing if it would be a proper site for the operation of the ecosystem conservation fund return project by analyzing the ecological environment, human environment, and the current status of land owners, the target species for vegetation restoration was determined, and the facilities and programs were selected in accordance with the spatial division of the biosphere reserve. The basic direction is as follows. First, is the expansion of green space and the securement of life habitats downtown. Second, is the conservation of core areas by separating the conserved area from the space for use. Third, is the establishment of ecological resting space and the reinforcement of an ecological educational programs. The significance of this study is to suggest a vegetation restoration plan of a coastal area, fully utilizing the existing vegetation of the subject area, by suggesting the land use and flow planning, environmental improvement (vegetation restoration) plan, life habitats establishment plan, planting plan, and hydrologic plan, facilities, maintenance, and monitoring plan based on the basic direction. This study would provide useful basic data for ecosystem conservation and restoration in the Korean Peninsula, surrounded by the ocean on three sides.

Lifeline service disruptions can have significant impacts on local community in the aftermath natural disaster. Although effective restoration strategies with accurate damage assessment are required, the internal complexity of lifeline networks and their interdependency makes the understanding restoration process of lifeline systems a difficult issue. Additionally, the limitations of previous research relating the influence assessment of lifeline to community disaster resilience, highlight the need for understanding of lifeline networks. Therefore, this paper presents an agent-based model to discover emergent behavior and evaluate the interdependency and resiliency in lifeline networks. This research will provide basic guideline of resource allocation in order to mitigate cascading failures of the post disaster restoration processes.

This study was carried out to classify vegetation structure of the Anseong district in the Deogyusan National Park from May 2007 to September 2008 using the gradient analyses and phytosociological method. The vegetation communities were classified into Quercus mongolica, Carpinus laxiflara, Q. serrata, Fraxinus mandshurica, Betula davurica, B. costata, Pinus densiflora and Abies koreana. Characteristics of the vegetation such as species composition, layer structure, vegetation ratio, and the distribution of individual trees by DBH were significantly different among communities. The order of important value of the forest community with DBH 2cm above plants was Q. mongolica (40.02), C. laxiflora (25.65), Q. serrata (24.68), F. mandshurica (21.66), P. densiflora (19.12), Acer pseudosieboldianum (16.96), C. cordata (11.87), B. davurica (11.66), B. costata (10.90), Styrax obassia (10.90) and A. koreana (10.41). Distribution of DBH P. densiflora had a formality distribution, suggesting a continuous domination of these species over the other species for the time being. In contrast, F. mandshurica appeared limited to the valley of the sheet and a higher frequency of young individuals, suggesting a continuous domination of these species the development of a climax forest terrain. This study showed the correlation between each community and the environment according to DCCA ordination. The A. koreana community predominated on the northern slope of the park in the high elevation habitats which had many O-M. F. mandshurica community predominated in the highest elevation habitats which had many Moisture, EX-Cation and T-N. The P. densiflora community mainly occurred on the southern slope of the park in the low elevation habitats which had few Moisture, O-M and T-N. The Q. serrata community and C. laxifiora community appeared on the park in the middle habitats.

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.

The purpose of this study is to understand the vegetation structure of the Corylopsis coreana habitats in South Korea and their correlation with environmental factors, in order to provide basic data for preparing conservation. A total of 40 vegetation survey plots were established in around Southern region, Gangwon-do and Gyeonggi-do Province. The cluster analysis revealed four distinct clusters: Quercus mongolica-Pinus densiflora (QmPd), Castanea crenata (Cc), Quercus mongolica (Qm), and Pinus koraiensis (Pk). Among them, the QmPd cluster was selected as the representative community. Soil texture analysis that most areas consisted of loamy soil and were distributed on the northern aspects. The plantation, represented by Pk, exhibited a high content of exchangeable aluminum (5.227±0.342 mg/kg), suggesting the need for soil improvement and monitoring in these habitats. The canopy openness (forest gap) ranged from 11% to 21%, indicating a relatively closed canopy in many survey plots. Non-metric multidimensional scaling analysis indicated heterogeneous species composition between the QmPd cluster and the Pk cluster (total R² = 0.608).

This study is a base research for the restoration of village landscape of the Namhan-Sansung. The Namhan-Sansung has been recognized as a top destination for dining places. However, there have been increasing concerns about the village landscape and its rich historic and cultural heritages transformed into dining places. The village landscape of Namhan-Sansung should be reconstructed as a setting for education and loaming of Korean history and culture forgotten for a long time. The landscape also should be a space where resolute resistance and spirit of Korean people and a futuristic village space where environment friendly community environment harmonizes with daily lives. Restoration efforts of village landscape of the Namhan-Sansung can get to start from exploring the prototype of the village. In order to restore the prototype, it is important to review potential elements and setbacks. Based on the prototype of the Namhan-Sansung village, transitions of village landscape were reviewed and directions of restoration were proposed. Also, an improvement plan was proposed after reviewing problems in system and planning.

An attempt to clarify the landscape structure of urban areas was carried out on Mt. Hwangryung located in the center of Pusan, southern Korea. By means of aerial photographs and field survey, a vegetation map including land-use pattern was made. Landscape structure was described by analyzing the vegetation map. Landscape element types were classified into secondary forest, introduced plantation, and other elements including urbanized area. almus firma and Pinus thunbergii communities, introduced plantation elements, formed matrix and some secondary forest elements and the other artificial plantations of small scale tended to distribute as small patches in such matrix. The number of patches per unit area in secondary forest elements was more than that in introduced plantation element. The result on patech size was vice versa. As the results of landscape ecological analyses, it was estimated that differentiation of patches recognized in community level would be related to artificial interference and those in sub-communities levels to natural process such as progression of succession. On the other hand, restoration plans in viewpoints of restoration and landscape ecology were suggested to improve ecological quality of Mt. hwangryung.

This study was carried out to introduce current status and development strategy for an environmental restoration of stream side in Japan, and to consider a methodology which could be effectively applied for the environmental restoration of stream side in Korea. The strategy prospects of environmental restoration in Japan were summarized as follows: 1. We should establish a new paradigm of forest road, forest conservation and erosion control which can emphasize the restoration of the streamside ecosystem and reduce the effects of soil movement change in the areas. And we should maintain the biotic habitats to conserve native biotic community when we practice forest road, forest conservation and erosion control works. 2. In the point of view ecological conservation aspects, we should evaluate the effects of new forest conservation and erosion control methods which is emphasized on the restoration of the streamside ecosystem to apply desirable methodology to the environmental restoration of the streamside area. 3. In the past, the objective of forest conservation and erosion control was to fix a soil by construction of permanent structures. Whereas, the direction of future's forest conservation and erosion control needs to change new forest conservation and erosion control technology to prevent large scale soil movement but allow small scale soil movement to conserve sound ecosystem and biotic habitats. 4. The restoration of the streamside ecosystem should provide continuity of the streamside environment which allows desirable biological habitats, and environmentally sound facilities to harmonize the environment.

Ecological restoration aims to reverse the degradation of ecosystems that occurred as humans have affected landscapes. This study was conducted in part of a larger project to develop participatory ecological restoration procedures for disturbed areas in Baigdoodaegahn which is a major mountain range in the Korean Peninsula. The case of alpine farmland at Kangwon-do was selected to apply the theoretical framework of participatory restoration since the nutrient contents in alpine solid under vegetable cultivation degrade water quality in the watershed while farmers in the region are economically struggling due to imports of vegetables from China. The reciprocal model of restoration was applied to cope with interactions between human and ecosystem needs in ecological restoration. A series of environmental education and eco-tourism programs were developed and incorporated into the participatory restoration project to rebuild social-cultural aspects of the community as well as to restore the biophysically disturbed area while meeting both ecological needs and human needs. This study suggests that participatory projects will be more successful when experts support the local residents and citizens in restoration process, when leadership are developed through social learning, and when ecological, financial and social factors of restoration are integratedly considered.

In order to determine the changes in microbial community due to termites, soil microorganisms surrounding the termites were investigated. First, bacterial communities from soil with termites collected at Seonamsa temple, Suncheon city, Korea were compared by next-generation sequencing (NGS, Illumina Miseq). The bacterial composition of soil from Daeungjeon without termites and the soil from Josadang, Palsangjeon, and Samjeon with termites were compared. Next, the bacterial composition of these soils was also compared with that of humus soil cultured with termites. A total high-quality sequences of 71,942 and 72,429 reads were identified in Seonamsa temple's soil and humus soil, respectively. The dominant phyla in the collected Seonamsa temple's soil were Proteobacteria (27%), Firmicutes (24%) and Actinobacteria (21%), whereas those in the humus soil were Bacteriodetes (56%) and Proteobacteria (37%). Using a two-dimensional plot to explain the principal coordinate analysis of operational taxonomic unit compositions of the soil samples, it was confirmed that the samples were divided into soil with and without termites, and it was especially confirmed that the Proteobacteria phylum was increased in humus soil with termites than in humus soil without termites.
