  • Natural disturbances and human development can cause habitat fragmentation. Plant and wildlife can become isolated, and habitat fragmentation and shrinkage have been recognized as a key issue facing the conservation of biological diversity. However, eco-corridors can alleviate the problem by providing linkages between isolated patches. The purpose of this study is to plan the eco-corridor for connecting urban forest via the urban stream with low cost and to restore the ecosystem. The results were as follows (1) Falco subbuteo, and Dryocopus martius inhabit in the study site. They are protected species designated by Korean Ministry of Environment. Thus the study site should be preserved as urban wildlife habitat species biodiversity (2) If the biodiversity of the study site is maintained properly, the eco-corridor can be constructed with low cost.

  • All Papers on Ecological Landscape Degign in KILA from 1973 to 2003 are listed herein for finding research issues and trends. The emerging field of Ecological studies of landscape design is based on Landscape Ecology and Watershed Ecology, the Principles of which can be applied to surveying and evaluation, Planning and design, construction and management focusing preservation of wildlife habitat and niche. This field can be classified into six categories: 1. Sustainable site planning and index, 2. Ecological planning process and regulation, 3. landscape ecology and biotope map, 4. Watershed and eco corridor project, 5. Urban forestry and environment, and 6. artificial ground and restoration ecology. The following is the summary of the findings from Paper review: 1. Sustainable index shall be studied about more specified sites. Water recycling facilities, and reservation wet land need to be studied. 2. Policy and legislation research on Ecological design shall be researched by expanding of the application field. Nature park planning and management fields shall be considered as the main theme of green networking Parts. 3. Landscape Ecological studies should be connected to practical surveying data, e.g. the eco-maps published by Environment Ministry. Traditional culture and science should be joined with the modem science. 4. Eco-corridor planning will go with the scenarios and theories of watershed ecology. 5. Urban forestry shall be studied with the wildlife's behavior and habitat. 6. Restoration engineering techniques should be reconsidered with the wildlife's existence and environmental affiliation.

  • Rapid developments around the world have resulted in urban expansion, habitat destruction, habitat fragmentation, and pollution problems, which are the main reasons for the decline in biological diversity. The United Nations warns that many animals and plants will die out in the near future if this continues. This study was performed to propose a map of eco-corridor suitability analysis of Korean water deer(Hydropotes Inermis) to enhance biodiversity in Chuncheon city. Eight factors affecting habitat suitability were elevation, aspect, slope, forest type, distance to the road, distance to the stream, land use and green connectivity. Previous study analysis on the mobility behaviour of the Korean water deer(Hydropotes Inermis) produced a habitat suitability map by determining the threshold and assigning a value between 0 and 1 depending on the habitat suitability using the fuzzy function. A method of analysis was proposed for a number of eco-corridor through comparative analysis of the data from the produced habitat suitability map and the road-kill point. The previous studies were focused on Backdudaegan region and national parks except for urban cities. The potential habitat map of Korean water deer could be helpful as a way to prevent habitat disconnection and increase species diversity in urban areas.

  • In an effort to preserve biodiversity in increasingly fragmented green patches, Korea has been installing eco-corridors over or under some arterial or expressways. In a survey of 43 such eco-corridors installed up until the year 2003, some problems and issues were identified. Some selected overseas eco-corridors were also investigated to find implications for the improvements of future installations in Korea. Major findings are; - For most existing eco-corridors, target species are not specified and locations of the eco-corridors are not well considered, and consequently it is questionable if wildlifes are crossing them - Most of existing eco-corridors lack supporting facilities such as fences that guide wildlife to cross them and prevent them from running into the road - Planting on the eco-corridors is not sufficient, not diverse enough in species, and not very considerate of wildlife but designed and planted in a similar manner as in urban parks - Where target species are not well specified, the location, width, cross section, and other aspects of the eco-corridors can not be optimized - It is suggested that eco-corridors are planned at early stages of road planning so that the number and locations of eco-corridor(s) decided as necessary and even the alignment and design of roads consider the installation of eco-corridors in advance - Monitoring of wildlife crossings is needed for improved eco-corridor planning and design - Nationwide green network plan is desirable to be made first and eco-corridors fit into it.

  • The main purpose of this research is to discuss the urban heat island which will be caused by urbanization, especially by the construction of new town on a wide green zone. Over the last ten years, five new towns have been developed around the Seoul metropolitan area. However these new towns become bedroom communities and create traffic problems between Seoul and its surrounding areas because of an increase in population and a lack of roads and other infrastructures. The construction of another such new town is under consideration in the Pan-gyo area. But it is important that Pan-gyo remains a wide green zone. Many studies show that green space can play an important role in improving urban eco-meteorological, ameliorative capability and air hygiene. The objective of this study is to analyze the urban heat islands of Bund-Dang Si which was constructed in 1996 and of the Pan-Gyo area planned as new town. To investigate the local thermal environment and its negative effects caused by change of the land use type and urbanization we used LANDSAT TM images for extraction of urban surface temperature according to change of land use over 15 years. These data were analyzed together with digital land use and topographic data. As a study result, we found that the thermal island of this area from 1985 to 1999 rapidly increased with a difference of mean temperature of more than 12'E. Before construction of Bun-Dang Si the temperature of this area was the same as the forest, but during the new town construction in 1991, an urban heat island developed. The temperature of forest with a size of over 50% of the investigation area was lowest, which leads us to conclude that the forest cools the urban and its surroundings. The mean temperature of the residential and commercial area is more than +4.5$^{\circ}C$ higher then forest, so this method of land use is the main factor increasing the urban heat island. Urban heat islands and green space play an important role in urban wind systems, i.e. Thermal Induced Air Exchange and Structural Wind Circulation, because of their special properties with regard to energy balance between constructed urban and land. The skill to allocate land use types in urban areas is a very important planning device to reduce air pollution and induce the fresh cold air from green space. An urban climatic experiment featuring a numerical wind simulation study to show the air corridor will be published in a following research paper.

  • 국립공원 주변지역은 도시확장과 개발로 인하여 야생동물들의 이동통로가 단절되고 서식지들은 작은 조각들로 파편화되었다. 서식지의 파편화는 야생동식물들의 교류감소와 근친교배로 인한 생물들의 다양성을 감소시켜왔다. 무등산국립공원 주변지역의 생태축을 파편화 시키는 주요 원인은 묘지, 산맥 절개지, 도로와 공공주차장, 농지에 의한 산지잠식, 도시기반시설, 송전탑, 도시지역 등이다. 국립공원 주변지역은 국립공원과 도시지역의 생태계가 서로 교류하며 공생할 수 있도록 생태디자인을 통해 연결체계를 갖추어야 한다.

  • 본 연구는 고속도로 야생동물 유도울타리 설치효과를 분석하여 적정한 유도울타리 설치 개선 및 관리방안을 제시하고자 중앙고속도로 만종분기점~홍천나들목구간을 대상으로 수행하였다. 고속도로에 설치된 유도울타리는 포유류의 도로침입 방지효과가 있었으며, 방음벽, 낙석방지울타리, 2단 가드레일과 분리방호벽도 로드킬 예방에 효과적인 시설이었다. 유도울타리의 로드킬 저감 효과는 출입문이 설치된 높이 1.5m의 울타리보다 출입문이 설치되지 않은 높이 1.0m 구간이 로드킬 감소효과가 높아 출입문의 유무가 로드킬 저감에 중요한 요인으로 판단되었다. 또한 도로시설물의 연결지점에서 로드킬 저감 효과가 컸으며 출입문이 있더라도 관리가 잘되는 지역도 로드킬 감소효과가 높았다. 유도울타리는 설치연장이 증가함에 따라 로드킬 감소율이 높았다. 유도울타리 끝 부분과 절토부 주변은 로드킬에 취약하여 이에 대한 개선이 요구되었다. 울타리 유지관리용 출입문은 설치간격이 가까울수록 로드킬 발생량이 높아 출입문 관리가 로드킬 저감에 효과가 많은 것으로 판단되었다. 고속도로 유도울타리 설치 개선방안은 암반의 급경사 지역 외에 모두 설치되어야 하고, 도로상의 낙석방지책, 2단 가드레일, 방호벽 등은 적정 시설개선을 통해 유도울타리로 연결 설치되어야 한다. 출입문을 설치할 경우 자동개폐식 또는 중력개폐식으로 설치하여 개방을 방지하고 야생동물 탈출로가 조성이 되어야 한다. 겸용생물이동통로는 토양층 복원이나 식생공간을 조성하여 생물이동통로화 하여야하며 로드킬로 포식자에 의한 2차 로드킬을 막기 위해 사고난 사체는 즉시 도로외부로 처리가 되어야 한다. 울타리는 최소 사고예방 목표지점으로부터 양방향 500m 이상 즉 1,000m 이상 설치되어야 하며 가급적 다음 도로시설인 교량, 통로박스 등까지 연결하여 야생동물을 생물이동통로로 안전하게 유도하여야 한다.

  • The subject is to find green roofs' location as stepping stones in green-network in fine scale. The study site is Junggu, Seoul, which has core areas(Bukaksan and Namsan) and green areas(parks, etc.). Through literature review, the closer to core areas and green areas, target species reach green roof easier, and target species must be avifauna(flying species) and high class in food chain, because of possibility of reaching. So, Great Tits, inhabited in Namsan and urban bird, is target species. The location standard of green roofs, realized birds' reaching distance, consists of home range(horizontal range and vertical range) and roof-greening capable area. The green roofs' distribution of location was resulted through GIS analysis of feasible site finding, and classified with weight of score. In discussion, Namsan gives more effect to locate green roofs than Bukaksan does and selected buildings which are grouped in some parts need to be managed with group, green roof district.

  • This study tried to propose the guidelines for the ecological preservation zoning in Korea. So some related laws and regulations were inspected, which were Natural Environment Preservation Act, Nature Park Act, Cultural Asset Conservation Act, Forest Act and Urban Planning Act. In these acts, I could find several concepts related to the ecosystem that are described as the protection area. But there aren't detailed and practical characteristics in those concepts. So for making the practical concept of ecosystem preservation, I considered Multiple Use Module, Wildlife habitat model, and Environmental evaluation model. Thorough this step, the process and methodology was established for evaluating and analysing. The potentiality of the GIS system was inspected. So the TM5 scene of the site was acquired and processed by ER-Mapper, Idrisi, Arc/Info and Arcview. And several digitized data were input by scanning and vecterizing. The Erdas format was mostly exchangeable to any program. The site is the Byonsan Peninsula National Park. The forest stand information and topographic data were digitized, types of which are forest year, DBH, density, slope, aspect etc. And also the watershed boundary, roads and paths, natural and cultural resources were mapped and analysed. Modelling of preservation suitability found the dispersed patterns for the best suitable zone through all the site. And the development potential areas were checked on downwatershed. This patterns are thought to result from the forest location for the wildlife habitat and the low altitude and no-steep slopes for developing. And Early warning system concept was introduced by overlapping these two patterns on the both potential area. As the conclusions, I proposed that the preservation zone be assigned according to the watershed unit as the main ecosystem zone. This main area should be linked by the eco-corridor through the point type eco-system. Finally, I thought the comprehensive information system should be established for making the rational and efficient decision making in natural area.
