본 연구에서는 서식지 질적 평가에 대한 추진체계를 6단계로 구분하고, 평가 대상지 선정 방법과 서식지 질적 평가 항목을 제시하였다. 서식지 질적 평가 항목은 서식지의 건강성, 안정성, 단절화 및 파편화 정도, 서식지 적합성, 위협 정도 등에 대한 종합적인 평가가 가능하도록 구성되었다. 그러나 현시점에서는 자료부족으로 인하여 서식지 질적 평가 체계가 적용 가능한 멸종위기종이 극히 일부에 해당된다. 서식지 질적 평가 체계는 향후 멸종위기종들에 관한 서식환경자료가 축적되고 이를 기반으로 평가항목들에 대한 정량적 기준 및 가중치가 부여되면 멸종위기종별 주요 서식지에 대한 보전방안 마련에 크게 기여할 것으로 기대된다.

This study was conducted to develop an ecological park planning model to enhance the functions of habitats and ecological corridors in Green Belt Areas, because changing policies have resulted in the degredation of the Green Belts due to progressive fragmentation of ecosystems. The principal outcome of the study is to plan an ecological park model through the restoration of habitats. In order to evaluate the capacity of the model to enhance the ecological functions of habitats and ecological corridors in Green Belt Areas, a simulation of habitats was carried out in the Sungnam-Yusoo region. The model was developed via following steps: 1. Selection of candidate sites and selection of the study site by analyzing development factors; 2. Selection of target species that can represent the habitat at the site; 3. Analysis of the site's suitability index for the target species; 4. Establishment of a conceptual plan to enhance and expand the currently produced suitability index; 5. Creation of a master plan based on the conceptual plan; and 6. Evaluation of the enhanced and expanded suitability index of the site. The study showed that the Habitat Unit (HU) of Rana coreana, which was selected as the target species of the study, increased from $28,044m^2$(3.6%) to $224,352m^2$(28.8%), and the HU of the site as the ecological corridor for wild animals increased from $4,674m^2$(0.6%) to $152,684m^2$(19.6%). The study results show that the ecological deficits of the Green Belt Area can be overcome by enhancing the ecological functions of the region, which should be beneficial. The model could be utilized for effective enhancement and management of other Green Belt Areas.

The playgrounds installed in the city try a variety of changes in play equipment more than traditional playgrounds, these playgrounds with formal rides are still different from nature friendly playground. For this reason, when in 2014 the department of environment pushed forward 'Aitteulag' project constructing ecological playground, the department aimed to provide the natural ecological spaces that are insufficient in the city and act as play space for children, leisure and community space for residents. Therefore, after inspecting 10 ecological playgrounds in Europe and Japan, in this study we suggested the construction guidelines of ideal ecological playground by comparing and analyzing these cases. We checked the environment-friendliness of these playgrounds in the 2 fields (playground component, ecological program) based on the ecological playground guidelines presented by the ministry of environment. The playground components are classified as siting location, spatial configurations, natural elements, play area, amusement facilities, play materials, open spaces, additional facilities. The ecological programs are divided into habitat, species, natural material, five senses. The following is the summary of the results about the reflection of eco-friendly planning factors. In terms of "habitat": bush and shade wood were highest at 95%. In terms of "species": local indigene(100%) and habitat for insects(95%) were higher than others. In terms of "natural material": wood(61.1%) was the highest. In terms of "details of wood(61.1%)": wood fence (95%), exploring wood and using sticks(85%) were higher than others. In terms of "five senses": hearing (32.1%), tactile(26.4%), and visual(23.9%) were in order. Therefore, on the basis of these results, this study proposed the planning factors that should be considered and complemented more in the construction of domestic urban ecological playground in future.

The purpose of this study is to develop design model of ecological park as stormwater storage facilities. The results are as follows : First, the design model of ecological park as stormwater storage facilities consider ecological and landscape characteristics such as high efficiency of land use, function as disaster prevention, ecological water purification, formation of habitat for flora and fauna. Second, this study demonstrates two types of plane structure and eight types of designed section. They can be combined and designed depending on conditions of each site. The facilities of stormwater storage conduct disaster prevention system and ecological park. Retention pond in stormwater storage facilities for ecological park also should be made for ecological restoration in the site. Third, the ecological park provide the basis for ecological network from in-site to out-site. Therefore its conservation and restoration plan consider the ecosystems of the site. Fourth, the most important factor for maintenance and management for retention pond is keeping water quality. Sustainable Structured wetland Biotop system is suggested for ecological water purification system in the retention pond which is one of the constructed wetland system using multi-celled aquatic plant and pond. This system can also provide habitat for animals and plants, water friendly park for men, and beautiful landscape.

This is a study on how to create an ecological arboretum that would promote biodiversity by creating wild animal habitats in terms of using large-scale remnants in urban areas and that would serve as a field for environment education based on its locational feature of being an urban area and its accessibility. This study is significant in a sense that this is the first arboretum to be created in urban area. However, it has a couple of limitations and they are as follows. First, since an arboretum creation plan is a mid/long-term plan, it is difficult to verify the biodiversity promotion effect of the application of habitats and creation techniques. Second, as the space was created by considering ecological features and utilizing natural prototype, the diversity of forest trees in here is lower than that of a traditional arboretum.

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.

The Antarctic clam Laternula elliptica, is one of the most representative benthic invertebrates in the Antarctic nearshore waters. Endemic to the Antarctic, L. elliptica is widely distributed around the Antarctica occurring as dense patches in shallow sheltered areas and exhibits high biomass. Despite its apparent ecological importance, L. elliptica has rarely been studied until recently probably due to difficulties in sampling in the ice-impacted waters. Recent studies have revealed various aspects of its ecology and physiology. In this review, some physiological and ecological characteristics of this species are discussed in relation to some prevailing features of its habitat environment, in particular physical instability of habitat substrates and extreme seasonality of food availability.
