  • The purpose of this study is to improve Biotope Area Ratio(BAR) systems used in the various fields. Recently, there has been increasing demand in urban agriculture as well as more residents cultivating farms on a small scale. However, there are few measures in terms of architecture and urban planning to respond to this trend. In this sense, this research is effective as it can respond to these demands by using BAR systems. Yet, the environmental indexes are not enough since BAR systems only take account of vegetation. Therefore, this study proposes an alternative way that includes the capacity factor of the plant growth by expanding the existing BAR systems. Thus, the study analyzes the complementary possibility of BAR systems, including elements of daylight, planting interval, area and soil depth with existing BAR elements.

  • This study focused on improving the Biotope Area Ratio, which has existing availability as a legal and institutional method for the architectural and urban fields to respond rapidly to recently growing demands for urban agriculture. The existing Biotope Area Ratio indicators only considers the depth and permeability of soil among a range of conditions for plant growth; they can be used for landscaping plants management but have difficulties in dealing with plants that are the major factors in urban agriculture. This study aimed to verify this hypothesis and suggest a direction of improvement in the Biotope Area Ratio. The study discovered that the management of plant growth only using the Biotope Area Ratio indicators has limitations.

  • 1990년대 후반부터 시작된 자연형 하천정비 사업은 기존의 수질보전정책 외에도 하천생태계에 대한 관심이 부각되는 계기로 작용하고 있다. 이 중 환경생태유량은 기존의 하천유지유량보다 확대된 개념으로 수생태계 건강성 회복을 위한 중요한 요소이다. 본 연구에서는 도시하천 수생태계 건강성 회복방안 마련을 위한 기초자료 마련을 위해 부산의 대표적인 도시하천인 온천천과 학장천을 대상으로 환경생태유량을 산정하였다. 환경생태유량은 하천의 물리적 특성 및 어류·유량을 조사하는 하천현장조사, 서식지적합도지수 산정의 과정을 통해 산정된다. 온천천과 학장천에서 각각 3개의 대표지점을 선정하고 각 지점별로 2회의 현장조사를 통해 각 지점에서의 수심, 유속, 하상재료, 어류 조성을 조사하였다. 조사결과를 바탕으로 붕어와 참갈겨니를 대표어종으로 선정하고 Instream Flow and Aquatic Systems Group(IFASG, 1986)에서 제시한 방법을 이용하여 서식지적합도지수를 산정한 후, 미국지질조사국의 물리적서식지모의시스템(PHABSIM)을 이용하여 하천별, 어종별 환경생태유량을 산정하였다. 온천천의 경우, 붕어와 참갈겨니 모두 약 0.7~0.8m3/s에서 가용서식지면적이 가장 크게 산정되어 일 60,000~70,000m3 가량의 환경생태유량 공급이 필요한 것으로 나타났다. 학장천의 경우, 붕어는 약 0.6~0.7m3/s, 참갈겨니는 약 0.3~0.4m3/s에서 가용서식지면적이 가장 크게 산정되어, 각각 일 50,000~60,000m3, 25,000~35,000m3 가량의 환경생태유량이 필요한 것으로 나타났다. 본 연구로부터 산정된 환경생태유량을 금번 관측유량 및 현재의 하천유지용수 공급계획량과 비교해보면 온천천에서는 일 15,000m3 이상, 학장천에서는 어종에 따라 일 7,000m3 이상의 추가유량 확보가 필요한 것을 알 수 있었다. 특히 학장천의 경우, 어종에 따른 환경생태유량의 차이가 크게 나타나 하천 구간별 유량조사를 통해 어종별 주요 서식지 구간 설정 및 관리가 필요할 것으로 판단된다.

  • This study looked for ways to carry out development projects in a sustainable manner by generating improvement plans, and focused on reviewing the status and problems associated with the environmental and ecological planning that is currently applied to new town and large-scale development projects. Improved methods were suggested based on differences between urban development and housing development projects. Based on principles set for the introduction of environmental and ecological planning, the size of the projects subject to environmental and ecological planning was set. With regard to the procedural improvements for environmental and ecological planning, nine problems were singled out from the development planning phases. Solutions were suggested by separating the problems into the site and district designation phase, development planning phase, implementation planning phase, and post-management phase based on a literature review and the opinion of experts. In consideration of improvements to the planning system, the scope of environmental and ecological planning was set after looking at information related to environmental and ecological planning, literature review, expert interviews, and the relevance of related plans. The scope of the environmental and ecological planning was divided into the overview of planning, environmental and ecological conception, conception of spatial structure and framework, and urban environment regeneration and impact reduction plans. By synthesizing the above-described results, the functions of environmental and ecological planning, development planning, and environmental assessment and their inter-relations were defined. The defined inter-relations seem likely to be developed into a form that would enable sustainable land development.

  • This was preliminary research to develop the mapping method for the Urban Ecological Map. This research provided preliminary evaluation model for ecological conservation. The model was applied to Mt. Kwanak in Seoul, and the Urban Ecological Map was produced and tested. The results are as follows. First, some problems were found in the legal Ecological Map ; insufficient and only qualitative criteria for evaluation of the conservation value in an urban area, and exclusion of the areas designated by other was laws. Secondly, in order to improve the evaluation criteria for Ecological Map, some missed sites should be added to the legal list of valuable sites. Those are needed for ecological restoration, conservation of wildlife habitats managed by a city government , and establishment of eco-corridor. Third, the efficient mapping process for Urban Ecological Map must have two steps. On the first step an ecological evaluation should be done based on pure conservation value. On the second one the Ecological Map for legal action control should be made. And the Analytic Hierachy Process is considered as a Helpful technique for improving the objectivity of evaluation model. Fourth, the legal action control system for Urban Ecological Map should be reviewed.
