  • Recently it is urgent issue in every department that problem from environmental disruption such as global warming. As the case of streetscape works essentially at city scenery, it is inevitable that changing from present view, which centers facilities and buildings, to environmental harmonic scenery. This study plans climate adjusting ability and improvement of thermal efficiency by putting ecological elements to buildings on a street which are essential factors of streetscape. Ultimately, this not only makes a pleasant environment but also revives being withered earth. Street-environment on eco-scape will take a part in designing sustainable city. This study acquires the way how buildings on a street get applied ecological elements as following. Roof level part : the greening surface of the rooftop(included plant box type), the greening roof as a type of pergola, the greening surface of the middle floor rooftop(included plant box type). Elevation part : climbing type, downfall type, espalier, flower bed in balcony type, wall-installing type, water wall type, other design types. Ground level part : paving the whole surface with permeability, paving the gap with permeability, plant box type, ground plant type, waterside zone, wetland, fence greening type, terrace greening type, retaining wall greening type.

  • This study is intend to evaluate natural conservation value, and to suggest natural park plan based on conservation value evaluation. In this study evaluation items are selected through related studies about ecological conservation evaluation, and evaluation items in this study can be classified into 2 aspects, ecological environment and topographic environment. After each evaluation items are overlaid with GIS program, management levels are derived from comprehensive overlaid maps of each evaluation items. Management areas can be classified into 5 levels; Critical Conservation Area, Conservation Area, Restoration Area, Passive Usable Area, Active Development Area and Settlement Area. So management areas can be matched each management levels to land use of natural park, that is district of preservation, district of natural environment, district of settlements and district of mass facilities. This study have good enough to evaluate ecological value for natural park plan, but, it is difficult to evaluate conservation value only with maps of each evaluation items, so it needs supplementary field survey for precise conservation value evaluation.

  • The purpose of the present study is to estimate the ecological instream flow for conservation and restoration of fish habitat in running water ecosystem which has very important status for stream environment. Estimation of the ecological instream flow in the present study was carried out by application of a two-dimensional depth averaged model of river hydrodynamics, River2D model. It can model fish habitat in natural streams and rivers and assess the quality of physical habitat accoriding to the species preferences for habitat suitability. Zacco platypus and Zacco temmincki were selected as target fish species in the study area of the Seomjin river. The Habitat Suitability Criteria (HSC) developed by Sung et al. (2005) were used for target fish species, life stages and habitat conditions in the study. Weighted usable area (WUA) was computed by the River2D model considering preferences of target fish species for velocity, depth, and channel substrate. The result revealed that the ecological instream flow of $10.0m^3/s$ is needed to maintain the target fish habitat at each life stage in the river.

  • 본 연구는 태백산국립공원 백두대간 생태축 연결을 위한 평가항목 및 요인별 가중치 설정을 위해 공원관리와 생태계조사, 생태환경계획과 관련된 분야별 전문가 대상의 설문조사를 토대로 계층화 분석을 실시하였다. 문헌연구와 담당자 면담조사로 생태축 연결을 위한 상위 평가지표 4개와 하위 평가지표 13개를 선정하였으며, 일관성 분석에 의한 유효설문을 대상으로 항목별 가중치를 산정하였다. 분석결과, 상위평가 지표에서는 생태계 가치증진이 0.474로 가장 높고, 자연-인간 갈등완화(0.247), 지역주민의 참여(0.165), 경제적 측면(0.114) 순으로 나타났으며, 하위 평가지표에서는 생물이동경로(0.116), 경관생태적 패치 연결성(0.112), 기능적 서식지(0.099) 등이 중요 항목으로 추출되었다. 분야별 평가항목과 가중치 비교에 따르면 생태계조사 분야에서는 생물종 이동경로(0.116)을 가장 중시하는 반면, 공원관리 분야에서는 기능적 서식지가 0.110로 가장 중요한 항목으로 평가되었으며, 생태환경계획 분야에서는 지역의 보전 및 이용자원 분포현황이 0.123으로 가장 높게 나타났다. 본 연구결과는 태백산국립공원 일대의 생태축 연결에 필요한 조사항목의 선정이나 분야별 연결성 분석방향 설정에 기여할 것이다.

  • For the purpose of building up the construction prospects of highway in consideration of natural environment. The tree planting and flower seeding in highway road side using native species were offered to natural landscape and resting area landscaping for peoples, and these area were 194place. The tree planting and flower seeding activity is to improve driving circumstances, and to conserve living and natural environment along the highways. And, preparation of ecotone and biotope at the highway surroundings for natural ecosystem conservation is an important activity, and planting of natural plants is generally carried out near wildlife ecoroads in order to give the way for animals. The primary purpose of this tree planting and seeding is not only to reduce environmental pollution, but also to enhance the ecological surroundings of highway circumference. Ultimately, It is essential that the constructive method of highway think over such as ecological environment and road design, surveying and management, construction, highway maintenance etc.

  • An Ecocomplex is proposed for ecological design of the estuarine environment of Han River, which is designed upon an alternative mamagement concept of estuarine environment. The concept reveals interrelationships among estuary, delta region and urban inland with inputs/outputs and feedbacks among them. The Ecocomplex emphasizes an integration of wastewater treatment with aquaculture, agriculture and recreation, and carries out ecological treatment, recycling, and harvest processes. A module of wastewater treatment pond system is employed in the Ecocomplex, which treats a flow of 3,786 ㎥/day and is composed of a four-facultative-pond series. Treatment ponds stabilize wastewater discharged from the urban area, and concurrently produce algae for commercial or recreational fish farming. Effluent from treatment and fish ponds is reused for agricultural production. Through the waste-algae-fish-vegetable-recreation processes, wastewater from the urban settlement is recycled back to the urban ecosystem. This resource-conserving design approach can maintain a sustainable urban ecosystem, managing an estuarine environment more naturally, healthly, and economically.

  • The concentrations of trace metals and organic matters in marine sediments collected from southeast Korean coastal areas were investigated. The primary purpose of this study was to evaluate the contamination status, spatial distribution and potential ecological risks associated with the physiochemical composition in the studied areas. We found that the concentrations of trace metals in marine sediments were as follows: Fe > Mn > Zn > Cr > Pb > Cu > As > Cd > Hg. According to the sediment quality guidelines (SQGs) of Korea, concentrations of Zn, Cr, Cu and Cd at all sampling sites were below threshold effect levels (TEL). However, concentrations of As, Hg, and Pb (i.e., at the 94-98% of sampling sites), were below the TEL. In addition, concentration factors (CF) in the surveyed area were found to be associated with low ecological risks, whereas As, Hg, and Cu showed moderate to high risk levels in some inner parts of the studied bays. Finally, the pollution load index (PLI) and ecological risk index (ERI) of the elucidated metals were linked to moderate ecological risk, pointing to the possibility of being deleterious to some benthic organisms.
