For both a healthy environment and sustainable development, we frame a habitat assessment method, concerning biodiversity and physical characteristics. With the method, we set up and extract conservation areas from Peace Valley Resort Development Areas which can function as habitats. Absolute and relative assessment items which are the size of area, habitation of species with conservation value, distribution of communities, functions of habitats, ratio of non-native plants, connectivity of habitats, vegetation layers of forests and age of forests, and water systems are considered on newly extracted conservation areas, and the habitat value assessment was calculated on the items in a 3-point scale. By comparing and examining 3 existing proposals for extracted conservation areas, we assess existing proposals, make an alternative proposal, and try to verify the possibility of applicability to extracted conservation areas. Proposal A and C must not be adopted since almost all conservation areas would be developed in the proposals. Proposal B, consisting of 53% development areas and 47% non-development areas, does not have enough development areas, so high density building arrangements should be encouraged in order to preserve conservation areas. Therefore, proposal B would be the best in ecological terms among the 3 proposals, if 3 conditions are considered : 1) new extracted conservation areas should be conserved; 2) 10~15m wide green-zones on both sides of the water system, which can play a role as ecological corridors, should be considered in development areas; 3) building arrangement should not interrupt the ecological corridors.

This internet search was made to collect background information for a short-term training proposal for securing a national critical mass in ecological risk assessment the need of which is drastically increasing in every sector of Korean society due to the advent of new environmental regulations in industrialized countries, such as EU REACH. This study depended mainly on internet search engines and individual home pages of concerned universities, colleges, and organizations involved in short-term training. Out of lecture titles and syllabus of 200 Korean universities, 86 Japanese national universities, and numerous English speaking educational and training institutions in the world, 60 syllabi were selected and analysed for comparison purpose. Conclusion from the analysis is as follows: Firstly, individual component lectures for ecological risk assessment is provided at different departments in Korea, but no lecture is at present given under the sole title of ecological risk assessment. Secondly, several lectures under the title of ecological risk assessment are open in English-speaking industrialized countries. Lectures as well as technical training and field studies are emphasized in those courses. Lecturers from the regulatory authorities are also involved in those courses. Several short-term training courses are also under operation. Thirdly, it was concluded that the difference in the level of education/training in ecological risk assessment is originated from the substantive requirement of ecological risk in the concerned laws and regulations. Therefore, it is suggested that training of domestic man power in this area is urgent to cope with the industrial pressure imposed by the environmental regulations concerned with chemicals/articles import and export from/to industrialized countries and also to upgrade the domestic laws and regulations.

Evaluation methods are employed in environmental impact assessment to choose between different project site, to determine the required measures to compensate impact and to decide whether the environmental impacts are more important than the social or economic effects of a project. The main obstacles that restrict use of quantitative evaluation method are a Lack of knowledge about the environmental effects (e.g. if impacts on wildlife or landscape amenities are predicted) and the relative importance of economic and social issues compared with nature conservation stability of ecosystem or landscape beauty. In Germany, the most common method for site planning is the "ecological risk analysis". It is a kind of multi-criteria-decision-method based on quantitative and qualitative description and ordinal ranking. The various kinds of "ecological balancing methods" that are more recently developed (within the last decade) to quantify the required amount for compensatory measures instead often use cardinal figures to express the value of ecosystems, the intensity of impacts, the need for additional measures to compensate for long recuperative periods when restoring ecosystems and so on. There are still only a view attempts to quantify decisions between environmental and socio-economic issues. Multicriteria-analysis as well as cost-benifit-analysis was used. Some new approaches which are still in a preliminary status are based on contingent valuation and on calculations for compensatory payments (instead of compensatory measures).

본 연구의 목적은 콘크리트 U형 벤치 플륨관 수로에 설치되는 수로 탈출 경사로의 경사각에 따른 개구리 행동 특성을 분석하여 탈출 경사로 기준 각도를 제언하는 것이다. 실험 장치는 현장에서 적용되는 콘크리트 수로 탈출장치와 형태 및 재질을 유사하게 제작하였다. 경사로 실험을 위해 논 습지에 서식하는 한국산개구리를 선정하였다. 경사로에서 보여지는 개구리의 주요 행동은 '뛰기', '걷기', '미끄러짐'이었으며, 경사각에 따른 행동 결과를 기록한 후 통계 분석하였다. 경사각은 20°-60° 범위에서 10° 간격으로 5개의 경사각을 설정하여 비교·분석하였다. 연관성 검증은 카이제곱 검증 방법을 사용하였다. 분석결과 30°와 40°는 통계적으로 유의한 차이가 없었다. 이는 '생태통로 설치 및 관리지침'의 30° 이하의 설치 기준에 있어, 현장에서 이를 40°까지 일부 허용해 줄 수 있는 근거로 활용될 수 있는 결과이다. 하지만 수로 탈출 경사로가 한국산개구리뿐 아니라 다양한 소형 야생동물을 대상으로 하고 있다는 점에서 추가 연구가 필요할 것이다.

급속한 경제성장으로 인한 대규모의 개발들은 산림, 농지 등 넓은 면적의 야생 동식물의 서식지의 훼손 및 단절을 유발하였다. 이와 같은 문제를 해결하기 위해 국토의 자연생태계를 하나의 유기체로서 인식하고, 생태적으로 우수한 서식지의 지속적인 관리를 통하여 자연생태계를 보전해야 한다. 특히 지자체에서는 생태적 연결성뿐만 아니라 환경생태적 우수성까지 고려한 광역생태네트워크를 구축하여 지자체 개발관련 계획에 적극 반영해야 한다. 이를 위해 국토의 생태적 연결성을 평가한 광역생태축과 우리나라의 환경생태적 가치를 정량적으로 분석하고 평가하기 위한 평가지도인 국토환경성평가지도의 환경생태적 평가 결과를 활용하여 지자체 광역생태네트워크 구축 방안을 제시하였다. 그리고 경상남도 사례로 지자체 광역생태네트워크를 구축하였으며, 구축 결과 기존에 구축되었던 광역생태축의 핵심지역 $2,986km^2$과 완충지역 $2,940km^2$가 확장되어 핵심지역은 $4,049km^2$, 완충지역은 $3,006km^2$으로 결과가 도출되었다. 개발계획 시 이러한 광역생태네워크의 참조는 지자체 생물다양성 증진과 생태계 보호를 포함한 지자체 통합적 환경관리에 크게 기여할 수 있을 것으로 판단된다.

This study carried out for establishing the synthetic restoration plan to improve ecological quality of Mt. Mudeung National Park based on the results of conservation value assessment for yellow-throated marten habitats. Yellow-throated marten has significant implications as umbrella species for the wildlife habitats conservation, therefore, this species could be used to ecological restoration plan of the damaged forest ecosystem in Mt. Mudeung National Park. In this study, we diagnosed the quality of yellow-throated marten habitats in Mt. Mudeung National Park based on five natural and two artificial factors. In addition, we evaluated the integrity of each zone divided by trails quantitatively based on land use intensity. As a result, forest landscape quality in Mt. Mudeung National Park was influenced greatly by human activity and the degree was depended on the intensity of trails. Therefore, in this study, we suggested the closing of trails composed of the illegal and 36 legal trails. And then, we modeled the changes of habitats quality of Yellow-throated marten for each closing step. As a result the area of core habitats increased by two times and wildlife habitats quality improved in the whole area of the Mt. Mudeung National Park. As a result, the results of this study indicate that man-made linear landscape elements play a key role in the quality of habitats for predators, which require large habitats area like the Yellow-throated marten. Therefore, in order to establish an ecological restoration plan in the mountainous area, we recommend the concept of the linear landscape should be applied with the concept of area landscape.

The purpose of this study was to compare the differences of the ecological attributes in the two types of urban park at Suwon and Goyang city. 'Directly linked park' is forests and rivers in the vicinity, it is capable of re-supply of the species and 'Isolated park' is forests and rivers apart, it is a difficult re-supply of the species. The result of assessment of the ecological attributes in the two types of urban park was analyzed as the percentage of 'Forest zone' was high, but the percentage of 'Area of permeable pavement' and 'Bush area' was low. 'The planting structure' was mostly 1-layer structure(47%) and 'Foreign tree species' is high by half the proportion. 'Age classes' were a 2-3age classes level, and 'Water body' could barely. Thus, ecological attributes degree was very low. In addition, results of investigation whether the difference of ecological attributes degree between the two types of urban park, also statistically analyzed that there is no difference. Therefore, when establishing the composition of the future plans of the city park, to take full account of the ecological situation in the surrounding parkland, and identify the ecological potential with the parkland. Next, it should be designed and planned of the park that fully utilizing the potential of this ecological attributes.

The watersheds are functional geographical areas that integrate a variety of environmental and ecological processes and human impacts on landscapes. Geographical assessments using GIS recognize the relationship between interdependence of resources and ecological/environmental components in watersheds. They are useful methodology for viable long term natural resource management. This paper performs through the using hydrological analyses, landscape ecological analyses, remote sensing, and GIS. Indicators are items or measures that represent key components of the small watersheds, and they are developed to be evaluated. Some indicators are described that they represent watershed condition and trend as well as focus on physical, biological and chemical properties of small watershed. Also, ecological functions such as stability, resilience, and sensitivity are inferred from them. The model implemented in GIS allows to reflect the ecological and hydrological functioning of watershed. Methodology from image analysis, landscape ecological analysis, spatial interpolation, and numerical process modeling are integrated within GIS to provide assessment for eco-logical/environmental condition. Results are described from the small watershed of Gwynns Falls in Baltimore County and Baltimore City, Maryland, an area of about 66.5 square miles. The small watershed within Gwynns Falls watershed are subject to a number of land-use. But it is predominantly urban, with significantly lesser amounts of forest and agriculture. The increasing urbanization is ass-coiated with ecological/environmental impacts and citizen conflicts.

인간활동에 의한 토양오염은 지속적으로 발생되고 있으며, 이를 과학적이고 합리적으로 관리하기 위한 인체 및 생태 위해성평가의 중요성이 부각되고 있다. 하지만 국내에서 생태계를 수용체로 하는 위해성평가에 대한 제도적 장치가 마련되어 있지 않으며, 이에 대한 평가체계와 활용가능한 기반 마련이 필요할 것으로 사료된다. 본 연구에서는 국내형 토양생태 위해성평가(soil ecological risk assessment) 체계를 제시하였으며, 이를 수행하기 위한 구체적인 내용들을 정리하였다. 토양생태 위해성평가는 오염물질에 대한 생태계 보호수준을 의미하는 예측무영향농도 산출을 목적으로 하고, 토양생태 독성자료 수집 및 적합성 확인, 토양생태 독성자료 표준화, 생태독성자료 충족도 확인 및 예측무영향농도 산출, 생태위해도결정의 단계로 수행할 수 있다. 수집된 생태독성자료는 신뢰도지수에 따라 적합성을 먼저 확인하며, 필요기준(국내 서식종, 급 만성, 독성종말점, 토양특성 분류)에 따라 순차적으로 정리하여 평가체계에 적용하는 방안을 제안하였다. 예측무영향농도는 생태독성자료 수준에 따라 저신뢰, 중간신뢰, 그리고 고신뢰 수준 중 하나의 산출 기법을 이용하며, 이를 통해 최종적으로 생태 위해도를 결정하는 방식을 제안하였다. 본 연구는 차후 토양오염물질에 대한 생태위해성평가 지침 제정에 있어 기본 체계로 활용될 수 있을 것으로 사료된다.
