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.

우리나라 산촌마을의 경관구조를 경관생태학적 패러다임인 토지 모자이크 모형에 의해 해석하였다. 상대적으로 개발의 영향이 적게 작용하여 산림청의 산촌종합개발사업 대상마을로 선정된 전북 김제시 선동리 아직, 산수마을을 연구대상지로 선정하였다. 전형적으로 나타나는 마을유역의 면적(2.8∼2.0㎢), 마을구역 및 농경지의 면적율(27%), 숲의 면적율(73%)이 조사되었다. 패취 경계형태의 깔때기 효과 특성은 3차원적 지형요소와 풍수지리적 형국도를 원용하여 해석할 수 있었다. 패취 경계형태의 깔때기는 동물이동 주요 통로로 보며 하천에 의하여 형성되는 만입부는 물과 대기 흐름의 장소로 동시에 적용될 때 물질흐름이 해석될 수 있었고, 이러한 깔때기 효과의 개념은 풍수지리에서 사용되는 형국도에서 중심축과 지류축으로 나타나고 있었다. 이러한 내용은 산촌생태마을 계획. 설계 시 보전해야 할 숲의 적정 크기와 하천 및 능선의 녹지축 net-working을 하기 위한 기본적 틀로서 적용될 수 있다고 판단된다.

본 연구는 "환경영향평가 협의 시 생물이동성 제고를 위한 법 제도적 고찰에 관한 연구"의 후속연구로 환경영향평가 협의를 통하여 조성된 대부분의 생태통로가 원목적과 부합하지 않게 조성되어 야생동물 교통사고를 저감하지 못하는 문제점을 개선하고자 수행하였다. 단절된 생태계의 연결성을 회복하기 위한 대안으로 환경영향평가 시 제시한 생태통로가 실질적인 역할을 할 수 있도록 각 단계별 고려사항을 제시하였다. 따라서 본 연구에서는 환경영향평가 협의 단계를 계획, 설계, 시공, 모니터링, 유지 관리 등 5단계로 구분하여 실무담당자가 각 단계별로 검토해야하는 구체적인 항목을 제시하였다. 이로 인하여 원목적과 부합하지 않게 조성되어 야생동물에게 외면당하는 생태통로 조성을 막아 개발 사업으로 인한 서식지 단절을 최소화하고 생물다양성을 향상시킬 수 있도록 하고자 하였다.

This study surveys and analyzes the ecology of Gangseo area to be developed near Nakdonggang River and West Nakdonggang River in Busan - before its development. With the result of the surveys as its basis, the study also finds ways to conserve the area's bird habitats in response to the planned development. According to the site surveys over four seasons, West Nakdonggang River which is near the targeted development area is a wintering ground for migratory birds. Some representative bird types in this area are ducks, geese, and other water birds. There are even six legally protected species. The average altitude of their flight is calculated to be $92.4{\pm}18.8m$ and the main purpose for the migration is determined to be for food. According to evalution of the conservation value of the area, Nakdonggang River and West Nakdonggang River turns out to have the highest conservation value. Other areas are developable as long as it was environmentally friendly. Therefore, this study suggests incorporation of ecological parks and biotopes within the targeted development area along with the proposal for spaces in the surroundings where the wintering birds can rest and feed. Especially for the wintering birds that rest at Nakdonggang River and West Nakdonggang River, their flight direction and pattern was examined to determine that their resting ground should be located 50~100m off of the river bank. Furthermore, this study proposes ways to maximize bird habitat by building ecological corridors between the agricultural channel and other small streams in the targeted development area and the habitats in the surroundings. Lastly, the study suggests the construction of low buildings, at most 20m in height, near Nakdonggang River and West Nakdonggang River considering the birds' flight altitude and direction.
