  • 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 purpose of this research was influenced by the historical background of Japanese modern architecture by the circulation of Kuma Kengo's architectural works and he wanted to look at the values and directions he was pursuing and how they were expressed in his works. The results of the review are summarized as follows. First, metabolism was developed as a reaction of modernism in modern architecture, focusing on growth through infinite reproduction by looking at architecture and cities as organisms and by using unit space as cells. Kuma Kengo, on the other hand, argues that focusing on the possibility of decimation of unit members by sequencing the elements that make up the space smaller than the unit space is closer to an ecological architecture. Second, what Kuma Kengo says is "erase the architecture" that is naturally related to the environment and disappears when its use is exhausted. His argument is expressed in individual architectural works through 'visual erase', 'particle painting of materials' and 'independence through dependency.' Through this, Kuma Kengo's ecological architectural languages were influenced by the ecological causes of metabolism, but they differed from the perspective of seeing architectural circulation as an organism. If metabolism was intended to realize circulation with growth potential based on the module of unit space, Kuma Kengo sought to implement circulation with the extinction of the unit members of space.

  • The purpose of this paper is to classify two study sites into the biotope types and investigate the landscape ecological characteristics of them. This will be available for the rural planning in the aspect of environmental preservation. The summaries of the result are as follows. 1) In the result of the area assessment in biotope groups, a dry field (32%) and a paddy field (28%) are more than 50%, but settlement space and water space are less than 10%. The result shows the land use condition of rural areas. 2) In the investigation result of elongation, running water spaces are higher than other biotope groups relatively, it is because they long shaped and 1-3m narrow. 3) In case of Fractal index analysis, residential spaces and cultivated lands are investigated to be lower in numerical value, it is because they have the definite borders and get simple in the border of landscape by human intervention. 4) In case of dispersion degree, the dry field has the highest value because they are located close by forests spread widely around study sites. It means that the land which is used by artificial purpose get more value rather than natural lands 5) In the connectivity analysis, a paddy field and a residential space appear the highest. It is because residence spaces spread intensively through roads and a paddy field, through streams. 6) In rural landscape, the diversity of landscape is investigated to be simple. A paddy field and a dry field contain small sized patches that have been divided by human intervention. Besides, there appear much different vegetation around waterways and farm-roads.

  • This study presents an integrated evaluation method to assess the level of achievement of quantitative expansion goals and qualitative improvement goals based on the Aichi Biodiversity Target 11 for quantitatively expanding and qualitatively improving national protected areas. The quantitative evaluation indicators for national protected areas are the percentage of terrestrial and inland water areas protected and the percentage of marine and coastal areas protected. The quantitative evaluation indicators for national protected areas are selected as 6 indicators: 1) ecologically important areas, 2) ecological representativeness, 3) management effectiveness, 4) connectivity, 5) social equity and 6) integration. Ecologically important areas are an indicator which evaluates how many areas of particular importance for biodiversity and ecosystem services are included in national protected areas. Ecological representativeness is to assess how well national protected areas represent the ecosystem. Management effectiveness is an indicator which evaluates how effectively national protected areas are conserved and managed, and connectivity is an indicator to assess how well national protected areas are connected. Social equity is evaluating how equitably national protected areas are managed and the integration is assessing how much national protected areas are integrated into the wilder landscape and seascape. This study is significant in that it provides a perspective of qualitative improvement as well as quantitative expansion of national protected areas for biodiversity conservation through accurately understanding Aichi Biodiversity Target 11.

  • 본 연구에서는 홍천강 11 km를 대상으로 수변생태벨트를 조성할 경우 벨트 폭에 따른 하천 단절성 개선 효과를 분석하였다. 홍천강 대상구간은 기존의 연구에서 하천 단절성이 심화되었다고 보고된 구간으로, 대상지의 생태적 연결성을 증진시키기 위해 필요한 수변생태벨트의 적정 폭을 선정하고자 하였다. 이를 위해 하천을 1 km의 구간으로 구분하여 A-K의 총 11개 구간에 대한 도상조사 및 현장조사를 수행하였다. 또한 단절지수를 적용하여 도로, 제방 및 주변 토지이용 등에 의한 연결성 단절과 생태적 기능성 단절 항목을 평가하였다. 그 결과, I 구간에서 연결성과 생태 기능성 단절이 가장 큰 것으로 분석되었으며, 수변벨트를 조성하지 않은 현 상태에서는 구간별 평균값이 단절 2등급을 보이는 것으로 나타났다. 또한, 폭 10-50 m의 수변벨트를 조성하였을 경우, 연결성 단절에 대한 개선 효과는 미비하였으나 생태적 기능성 단절에 대해서는 12.4-25.1%의 개선효과가 있는 것으로 예측되었다. 한편, 10 m와 30 m를 조성하였을 경우 단절성 저감효과가 크게 나타났으며, 특히 30 m 조성시 단절등급이 2등급에서 3등급으로 완화되는 효과를 보이는 것으로 나타났다.

  • 본 연구는 2020년 장기미집행 도시공원의 자동실효(이하 도시공원 일몰)로 인한 생태네트워크 측면에서의 영향을 부산지역을 대상으로 분석하였다. 분석은 도시공원 일몰과 관련하여 가능한 5개의 시나리오를 구축하고 각 시나리오별 생태네트워크 변화를 FRAGSTATS의 경관지수들을 활용하여 살펴보았다. 일몰 예정 공원에 대해 전체 개발을 가정하는 시나리오 1은 해당 공원들의 전체 보전을 가정한 시나리오 5에 비해 녹지면적이 7,339.75ha가 감소하고, 생태공간의 파편화도 증가하는 것으로 분석되었다. 내부종 서식지에 영향을 미치는 중심지 비중도 8.06%이상 감소되며, 녹지 간 연결성도 28.23% 이상 감소되는 것으로 나타났다. 그러나 공원 내 생태적 가치가 높은 지역을 중심으로 보전하는 것을 가정하는 시나리오 3은 시나리오 5(전체 대상지 보전)의 94% 지역에 대한 보전이 가능하며, 연결성 측면에서는 95.6% 이상 보완이 가능할 뿐 아니라 생태지역 파편화 측면에서도 공원예정지 전체를 조성하는 것과 유사한 효과가 나타나고 있었다. 따라서, 일몰 예정 공원에서도 보전가치가 높은 지역을 중심으로 보전하는 것은 생태네트워크 측면에서 효과가 상당히 높음을 확인할 수 있었다. 현재 지자체에서 이들 보전지역을 중심으로 우선 해제를 시행하고 있는데, 이들 지역은 개발의 수준이 낮다고 해도 산발적 개발가능성이 높으므로 현재 추진 중인 우선 해제에 대한 재고가 필요하다고 판단된다.

  • 본 연구에서는 국립공원 자연관찰로의 특징(기호)과 초등과학 환경 관련 핵심개념 및 환경교과의 생태교육 영역과의 연계성을 분석한 후, 바르트의 기호학적 이론을 바탕으로 장소정체성 기호학적 해석모델을 개발하여 초등학생부터 성인까지 가능한 자연관찰로의 생태교육적 장소정체성 형성 과정을 분석하였다. 내장산국립공원의 원적골 자연관찰로, 소백산국립공원의 희방계곡 자연찰로와 한려해상국립공원의 금산 자연관찰로를 연구 대상으로 하였다. 자연관찰로의 해설판 중심의 주변환경과 생태교육 내용체계와의 연계성을 분석한 결과, '생태환경의 체계' 영역과 가장 높은 연계성을 보였다. 자연관찰로의 장소정체성 형성 과정을 기호학적으로 분석한 결과, 장소성 형성에는 지리적 위치나 경관, 인공적 환경, 주변자연환경의 특징인 물리적 요소가 대부분 작용하는 것으로 나타났다. 장소감 형성은 지식과 애착 요소가 동일하게 작용할 수 있는 것으로 나타났다. 이러한 장소성과 장소감 요소의 상호작용을 통해 형성될 수 있는 장소정체성은 행동적 내부 단계와 공감적 내부성 단계가 대부분이었다. 그러나 장소정체성 형성의 다양성을 위해서는 환경교육 프로젝트 개발과 자연관찰로 환경의 특이성이 반영된 주변환경과 해설판이 조성될 필요가 있다.

  • As urbanization progresses, there is a growing and continuous demand for green spaces that provide ecosystem services. However, increasing the quantity of green spaces within major cities is challenging. Therefore, it is essential to pursue qualitative improvements that consider ecological characteristics of existing green spaces. In this study, we focus on local neighborhood parks in Seoul and present the following two questions through an evaluation utilizing ecological design indicators and land use data: 1. Which factor, design or location, has a greater influence on the ecological quality of neighborhood parks in Seoul? 2. Additionally, when evaluating ecological characteristics, is there similarity between assessments based on land-use data and those utilizing ecological design indicators? For this study, we conducted research on 30 neighborhood parks in Seoul and classified them into mountainous types (adjacent to mountains, natural terrain parks) and urban types (independently designed within 300m without existing forests) based on previous studies. Firstly, we conducted evaluations according to park location types. When comparing the evaluation scores of urban types (14 parks) and mountainous types (16 parks), significant differences were observed with scores of 16.86 and 35.94, respectively. Statistical analysis showed a significant difference between park types. In terms of habitat quality, the average values for urban and mountainous parks were 0.33 and 0.53, respectively, and statistically significant differences were observed between park types indicating differences in ecological potential according to park location. Secondly, when comparing the results of ecological potential evaluations based on park design and external connectivity, a correlation was found between habitat quality and total scores according to evaluation indicators. The correlation analysis showed significant linear relationships between habitat quality and total scores, biodiversity scores, and ecosystem function scores, with high positive correlation coefficients of 0.829, 0.861, and 0.802, respectively. This study holds significance in analyzing the ecological aspects of urban parks through the lens of both park location characteristics and design indicators. The analysis results underscore the importance of planning and managing ecologically sound urban parks contingent upon their location. Moreover, the utilization of appropriate ecological design indicators can help alleviate environmental limitations surrounding parks. Integrating these considerations could enhance the ecological quality and ecosystem services of urban green spaces.

  • Ecosystem and environment have been a serious challenge facing the modern society. It's been the new paradigm from ecological view of the world and the alternative based on Orientalism. From the Oriental standpoint, ecological aesthetics and sustainable architecture are no longer new, which then servers the background of this study. The nature and the space, the life where the human is harmonized and integrated and the wish to make the balance through that life are the basic philosophy which the Orientalism has pursued. Based on such a basic concept, the study is intended to review the connectivity, expression approach and the features in Korean traditional residential space based on previous studies on ecological aesthetics and sustainable architecture. Such attempt is meaningful in seeking the possibility of presenting the new frame as well as forming the various views to the traditional space and spatial recognition. The nature was categorized into tangible element and intangible element and also direct approach and indirect approach before evaluating the characteristics. Sustainable architecture is not the concept to simply maintain or sustain the environment, but plays more important role in economical aspect. Traditional space accommodates the nature and circulation principle and the circulation in the nature controls the energy and enhances the efficiency, playing significant role. The nature itself serves the alternative energy and has the aesthetic element in such a way of concealing itself. This study is intended to analyze the Byulseo Jeongwon which formed many relations with the nature and the residential space, thereby identifying the expression characteristics of eco-aesthetic sustainable architect. This study offers the answers with regard to the coexistence of the expression characteristics of sustainable architecture with the nature, space and the human from eco aesthetic viewpoint as well as the solution in dealing with the ecological and environmental challenges. Furthermore, it suggested the possibility that the traditional space would possibly be succeedable in new and creative way and sought the way for coexistence among the nature, space and human and eco aesthetics, and finally paved the pivotal foundation as the sustainable design alternative in future.

  • Lately, besides promoting the biodiversity of the natural ecosystems, there is a demand for climate change mitigation features that will reduce greenhouse gases and prevent disasters that will bring damages such as torrential rains. However, there was not a lot of discussion on the soils that are key in these features. Therefore, this paper proposes a network (Gold Network) as an alternative that will solve the problem that was filed earlier by figuring out how to compose the soil environment. First, in order to maximize the ecological status and value of the soil, a soil network can be proposed through the vertical and horizontal connections of the fragmented soil. Second, there is a need to understand and research the organic system of the ecosystems as well as the complex perspective of the ecosystem services, not only the fragmentary perspectives of the soil remediation, planting improvements or the other existing elements. Third, there is a need to apply the integrated perspective of the Landscape Ecology, Ecological Engineering and Restoration Ecology for the connectivity of the soil (network) due to it being in the execution of the soil network. If a soil network was to be built, a fundamental ecological network would be realized to not only promote biodiversity but also to prepare effective adaptation to climate change.
