  • The present urban redevelopment has caused many problems. The truth is that the improvement of residential environment in this country has resulted in high-rise apartment buildings of the same form, without regard for vestiges of previous residents and regional characteristics. If redevelopment should be continued in a proper way to improve the right to adequate housing, a new form of urban design will be required, solving existing problems. For this, the cultural and ecological elements of the redevelopment site to be conserved and developed should be found and designed. Consequently, this study focuses on the cases of domestic and overseas urban design that cultural and ecological elements have been applied to redevelopment, and suggests Hwamyeong-dong, a deteriorated area in Busan, to design from a cultural and ecological point of view.

  • The Suncheon city has new city image and brand as eco & garden city in national wide. This paper reviews the process, governance, and performance of creative-city related policy in Suncheon city, Korea. The new city image and brand, eco & garden city, were as a result of the related urban policies and its efforts to reserve and utilize the Suncheon Bay Wetland such as the establishment of Green Suncheon 21, the Reed Festival of Suncheon Bay, the ecological park creation projects for Suncheon Bay Wetland, the ICEXPO 2013, and the Suncheon Bay National Garden since 1995. The Dongsa Research Institute has been played very import roles in the process of civic movement for Suncheon Bay Wetland reservation. After holding the ICEXPO 2013, the Suncheon city has achieved various performances such as new city image and brand, the Suncheon Bay National Garden, social and physical infrastructure to pursue future creative-city related policies.

  • Urban trees play an important role in absorbing carbon dioxide from the atmosphere, improving air quality, mitigating the urban heat island effect, and providing ecosystem services. To effectively manage and conserve urban trees, accurate spatial information on their location, condition, species, and population is needed. In this study, we propose an algorithm that uses a high-resolution urban tree cover map constructed from deep learning approach to separate trees from the urban land surface and accurately detect tree locations through local maximum filtering. Instead of using a uniform filter size, we improved the tree detection performance by selecting the appropriate filter size according to the tree height in consideration of various urban growth environments. The research output, the location and height of individual trees in human settlement over Suwon, will serve as a basis for sustainable management of urban ecosystems and carbon reduction measures.

  • As a result of the current trend towards promoting conservation of the ecosystem, there have been various studies conducted to determine ways to establish an ecological network. The development of analytical methods and an environmental database of GIS has made the creation of this network more efficient. This study focuses on the development of an urban spatial decision support system based on 'Landscape Ecology Theory'. The spatial decision support system suggested in this study consists of four stages. First, landscape patch for the core areas, which are major structures of the ecological network, was determined using the GIS overlay method. Second, a forest habitat was investigated to determine connectivity assessment. Using the gravity model, connectivity assessment at the habitat forest was conducted to select the needed connecting area. Third, the most suitable corridor routes for the eco-network were presented using the least-cost path analysis. Finally, a brief investigation was conducted to determine the conflict areas between the study result and landuse. The results of this study can be applied to urban green network planning. Moreover, the method developed in this study can be utilized to control urban sprawl, promote biodiversity.

  • 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.
