  • This study constructed a high-resolution bioclimatic classification map of South Korea which classifies land into homogeneous zones by similar environment properties using advanced statistical techniques compared to existing ecological area classification studies. The climate data provided by WorldClim(1960-1990) were used to generate 27 bioclimatic variables affecting biological habitats, and key environmental variables were derived from Correlation Analysis and Principal Component Analysis. Clustering Analysis was performed using the ISODATA method to construct a 30'(~1km) resolution bioclimatic classification map. South Korea was divided into 21 regions and the results of classification were verified by correlation analysis with the Gross Primary Production(GPP), Actual Vegetation map made by the Ministry of Environment. Each zones' were described and named by its environmental characteristics and major vegetation distribution. This study could provide useful spatial frameworks to support ecosystem research, monitoring and policy decisions.

  • Ecological approach to conservation of Korea's National Parks (KNP) was reviewed. Four hundred twenty five reports on 15 national parks for 80 years (1915~1994) were analyzed in consideration of phytocoenotic information such as flora, plant community and landscape. Total species was recorded as 157 familles, 752 genera, and 2,369 species (64.3% of Korean flora), in which is included only 75 species of the protected plant species designated by the Ministry of EnvironMent. Occurrence patterns of plant species in national parks were quite similar to one another, but those of plant community were rather unique. Seventy-four of 97 plant communities were reported in only one of 15 national parks, which might be regarded as an endemic or local vegetetation type. These facts are far different from actual status of the KNP's ecosystem, which indicate that not only original data in previous reports are less informative, but also tools of investigation and description are too subjective, and thus these can never afford to monitor the ecosystem. From the correlation analysis between 10 ecological characteristics, the following results were obtained: (1) the species richness was positively associated with the area of national park, (2) the number of visitors was related to landscape diversity, (3) occurrence of the designated species was closely related to the vegetation diversity. Numerical analysis (cluster analysis and ordination) using dissimilarity ratio by ecological characteristics divided 15 national parks into 4 groups. The first group, composed of national parks of Chirisan, $S\v{o}laksan$, Sokrisan, Hallasan, $T\v{o}kyusan$, Odaesan, and Sobaeksan, is recognized as the best national parks in terms of ecological conservation values. Nevertheless, they have been faced with the threat of visitor stress. This study will contribute to the establishment of strategy for appropriate conservation and sustainable use of KNP.

  • This is a study to generate a theoretical base for the development of wildlife corridor as a solution to the problems of wildlife population size reduction and declining bio-diversity resulting from the fragmented habitats caused by road constructions. This study seeks to examine and define techniques in very aspect of wildlife corridor including planning, site selection, design and development, and maintenance through an actual application. The results of this study are as follows. 1) The wildlife corridor should be developed in an approach supplementing a landscape ecological approach and a restoration ecological approach bilaterally. To this end, systematic methodology and process are required. 2) It was restored an ecosystem as close as possible go to the forest ecosystem before road development. In addition, in order to allow it to function as an ecological corridor, topography restoration, stream development, and ecological plantation were implemented. 3) The result of monitoring activities that continued for one year since the development confirmed the migration and inhabitation of a number of animals including small mammals. It is judged that it functions as a corridor in fragmented habitats as initially expected. 4) Through continuous monitoring in the future, the effects of corridor development on ecological restoration need to be reviewed in a long-term perspective. There is also a need to develop and refine a comprehensive maintenance plan for wildlife corridors and their surroundings. Based on such study results, actual data on the development of wildlife corridor should be accumulated. In follow-up studies, after continuous monitoring for a long period of time, the effects of wildlife corridor development should be evaluated comprehensively and wildlife corridor applicable to Korea should be standardized by correcting disclosed problems.

  • The purpose of this study is to evaluate the preference and image on landscape of before and after the restoration in the four study areas where the restoration project of Baekdudaegan ecological ridgeline was carried out and to explore the change factors of image preference according to restoration project. The study areas were Beoljae, Ihwaryeong, Bijoryeong, and Yuksimnyeong and 248 questionnaires were used for analysis. As a result of the recognition analysis on restoration project of ecological ridgeline, the awareness of the project was low at 2.63, the satisfaction of the project was 3.42, and necessity of the project was 4.07. In terms of the preference analysis for landscape photographs, the all preferences of four sites were improved after the project than before. In the result of the landscape image evaluation, images such as 'lifeless', 'uniform' and 'ugly' were high before the project, however, images such as 'clean', 'tidy', and 'stable' were high after the project. As a result of analyzing the change factors of image preference according to the restoration project, adjectives such as 'beautiful-ugly' and 'open-closed' influenced the preference change in common. These findings can be utilized as the base data for the planning direction for the construction of new ecological ridgeline or the landscape conservation of existing ecological ridgeline.

  • 도시공원은 지구온난화와 대기오염을 줄여주고 열섬현상을 완화시켜주는 중추적인 역학을 하고 있다. 그러나 도시공원 일몰제에 따른 2020년 7월 이후 도시공원 제한이 일부 해제될 예정이다. 이에 따라 정부와 지자체는 공원부지 확보와 더불어 생태공원 조성 등 공원 활성화를 위한 노력을 기울이고 있다. 그러나 도시공원 주변에 건설되고 있는 고층건축물에 의해 발생하는 빌딩풍은 보행자에게 불쾌감을 유발할 수 있고, 생태공원에 서식하고 있는 동·식물의 생태계를 위협할 수 있다. 우리나라의 풍환경 평가에 대한 기준은 명확하게 제안된 바가 없으며, 관련 연구 또한 찾아보기 힘들다. 따라서 본 논문에서는 국외풍환경 평가기준 및 관련 연구를 검토하여, 풍환경 평가 기준의 중요 인자를 도출하고, 국내 기상관측자료를 이용한 풍환경 평가에 적용 가능성을 검토하였다.

  • Purpose: This study aimed to explore ecological factors and strategies for childhood obesity prevention targeting vulnerable children using a community-based participatory research (CBPR) methodology. Methods: The CBPR was conducted by following basic process steps. Participants were 12 community stakeholders such as community child center directors (n=4), vulnerable children's mothers (n=3), community health center officials (n=2), and lay health advisors (n=4); they were purposively sampled from K municipal county in Seoul, South Korea. The qualitative content analysis was performed to explore main themes of the ecological factors and strategies by using data obtained from 5 times of focus group interview. Results: Twelve ecological factors associated with childhood obesity prevention were identified: Intrapersonal factors including emotional overeating; interpersonal factors including permissive parenting style of children's eating behaviors; organizational factors including social workers' less educational opportunities; and community/policy factors including less government financial support. Four ecological strategies for childhood obesity prevention were addressed: Developing obesity prevention programs targeting vulnerable children' lifestyles; promoting parents' active participation in education; building healthy meal service environments through empowering social workers; and building supportive community environment and securing community resources for child obesity prevention. Conclusion: Our findings may be informative in terms of providing a comprehensive understanding of multi-level ecological barriers against vulnerable children' obesity prevention and, moreover, guiding multi-level strategies for preventing childhood obesity targeting children enrolled in community child centers.
