  • 최근 부산시내 자연경관이 양호한 지역에 고층건물들이 무분별하게 들어서 도시경관의 핵심이 되는 산림스카이라인을 깨트리는 동시에 도시 내 녹시율을 심각하게 떨어뜨리고 있는 실정이다. 따라서 도시민들의 삶의 질과 도시경관의 쾌적성을 향상시키고 도시의 녹시율을 높이기 위해서는 산림스카이라인의 효율적인 관리방안이 마련되어야 할 것이다. 이를 위하여 본 연구는 기존 산림스카이라인의 관리를 위한 건축물 고도규제 수단으로 사용하는 시곡면 분석의 문제점을 보안할 수 있는 GIS를 활용한 다중시곡면 분석과 건축물 높이에 큰 영향을 미치는 용적률을 비교 분석하여 건축물의 높이 규제 방향을 제시하고자 하였다. 이를 위하여 연구의 공간적 대상은 부산시 남구 대연동 주변 주거지역을 대상으로 하였으며, 분석방법에 있어서 다중 조망점 선정을 통하여 객관성을 확보하는 동시에 효율성을 높였다. 또한 주요지점에서 시뮬레이션결과를 반영함으로써 종합적인 경관계획이 가능하게 하였다. 마지막으로 본 연구는 산림지역의 지리적 여건에 맞추어 산림스카이라인 보호를 위한 건축물의 높이 규제의 방안을 제안하였다.

  • Among components of digital topographic maps used officially in Korea, only contours have 3D values except buildings and trees that are demanded in landscape planning. This study presented a series of processes for 3Dreconstructing landscape features such as terrain, buildings and standing trees using LiDAR (Light Detection And Ranging) data and aerial digital photo graphs. The 3D reconstructing processes contain 1) building terrain model, 2) delineating outline of landscape features, 3) extracting height values, and 4) shaping and coloring landscape features using aerial photograph and 3-D virtual data base. LiDAR data and aerial photograph was taken in November 2006 for $50km^{2}$ area in Sorak National Park located in eastern part of Korea. The average scanning density of LiDAR pulse was 1.32 points per square meter, and the aerial photograph with RGB bands has $0.35m{\times}0.35m$ spatial resolution. Using reconstructed 3D landscape features, visibility with the growing trees with time and at different viewpoints was analyzed. Visible area from viewpoint could be effectively estimated considering 3D information of landscape features. This process could be applied for landscape planning like building scale with the consideration of surrounding landscape features.

  • This study Is about the situation of contemporary landscape architecture design in Korea. The conceptual framework of interpretation for landscape architectural works is formulated to define the design trends of today′s professional works The study′s analytical method is composed of the survey of attitudes questionnaire, the analysis of design composition techniques and conclusions drawn from the comments of contemporary landscape architectural critics. Among 975 members of the Korean Institute of Landscape Architecture, 318 professionals responded to the survey questionnaire. The survey revealed that landscape architects in Korea are concerned about the profession′s reduced contributions to the sharping of the built environment. However, they are optimistic about its future. Ten top design works were selected from the surveys′ answers and were analyzed for the design characteristics which could best represent the trends of the last thirty years. Several design critiques and comments about the professional works were cited to reinforce the outlined "-ty" of the contemporary design phenomena. The study identified the following distinguished design trends of contemporary Korean landscape architectural works They are as follows: Themelessty, Powerity, Traditionality, Monumentality, Non-contextuality and Over-designity. These trends identify the overall prevailing conditions of Korean landscape architectural design over the past thirty years.

  • Landcover change is an important factor that changes structure and function of regional ecosystem. As the rise of concern on environment quality, many studies are trying to quantify and evaluate the landsacpe in recent days. In this study, using landscape indices with RS(Remote Sensing) and GIS(Geographic Information System) technology, spatio-temporal variations of areas and distribution of forest patches were examined in the Chonan from 1985 to 1996. Fragstats 2.0 was employed to analyze and compute 31 landscape indices from 52 landcover maps. A result of this study showed that area of forest and paddy decreased as a result of urban sprawl. Especially from 1993 to 1996, the change of land use progressed rapidly because of merging a city and a country in Chonan. The size of patch in forest had been smaller and irregular form, heterogeneity of size of forest patches within sub-basin increased, and variety of patch types around forest patches increased from 1985 to 1996.

  • A city evolves over time. It grows, transforms, and sometimes degrades. Chuncheon is at a turning point from a city souggling with regulations regarding clean water supply and a military encampment to a masterpiece city with a sustainable vision. The city is getting ready to restructure itself to become a world-famous culture and tourism complex expanding its physical boundary across the Camp Page site and absorbing Jungdo as a major tourist attraction. The landscape in the future blueprint of Chuncheon will play a great role in restructuring urban form. The regenerated in will have a new networked open space system as well as re-evaluated landscape resources. The hybrid theoretical practice called 'landscape urbanism' burgeoning in the fields between 'landscape architecture' and 'urbanism' can guide us in considering the terms of the relationship between a city and landscape when we design a future city Landscape urbanism is considered to be an effective framework by which we can diagnose the current status of a landscape in our contemporary urban design practice in Korea. This paper tries to provide a different perspective from the viewpoint of landscape urbanism to decipher the hidden implications of the social agreement on the role of landscape in urban structure by re-reading eight design proposals presented for the ChunCheon G5 international design competition based on the main principles of landscape urbanism. The G5 design competition is a great opportunity to test out new ideas on a city, demonstrating the relative values among various urban-design professional realms. First, this paper provides an overview of the main ideas of landscape urbanism based on the literature review and case studies. Second, framework categories are suggested in order to extract the explicit and implicit ideas on the landscape. Third, eight proposals are reviewed according to the suggested categories to situate the current landscape design of Korea within the mainstream of contemporary practice of landscape urbanism. Based on the review of eight proposals, the following diagnostic conclusions are made; first, the ideas of landscape urbanism have not been actively introduced in large-scaled urban landscape projects in Korea like Chuncheon G5. Second, it remains to be a big task for landscape professions to be able to participate in design consortiums on an equal footing. Third, In order to introduce and reify the ideas of landscape urbanism in Korea, it is inevitable and critical to test the ideas in both academic fields and professional practices to find the appropriately adjusted model of landscape urbanism.

  • This study is based on the viewing characteristics of mountain landscapes. It investigates whether the current landscape management-related regulations are efficient in terms of the viewing characteristics of the mountain landscape against Bukhansan Mountain in which the conventional landscape management techniques were used. In addition, some viewing characteristics of mountain landscapes, such as distance from the view point to the target mountain, angle of elevation, altitude, gradient, have been analyzed and 3 cases of viewing condition have been simulated. The following results were obtained: i) Mountain landscapes can be managed up to 7~8 times of the mountain height with a $5{\sim}9^{\circ}$ of elevation angle. ii) In the Natural Landscape District which is situated on the hillside, it is reasonable to include altitude, gradient as criteria for regulation. iii) According to a simulation of the construction permit height by viewing distance, it was confirmed that buildings can be constructed up to 111.55m when viewing the 20% ridge, 150.75m when viewing the 50% ridge and 189.05m when viewing the 70% ridge. iv) The construction permit height varies depending on the landscape analysis method that is used and the application conditions. It is therefore unfair to apply height limit regulations to all buildings without considering the geographical features or viewing characteristics. v) It is unreasonable to apply 2~3 management techniques to the same area for landscape management. Therefore, we recommend the Focused Landscape Management Area based on the landscape master plan as a integrating mountain landscape management techniques.

  • Land development policy in Korea, characterized by its supply-oriented policy, has driven rapid economic development. However, it has a negative impact on the natural environment across the country. Especially, as the introduction of quashi-farmland system with the deregulation of agricultural land development in the late 1990s, numerous unfavorable landscape features such as road, motels and apartment have emerged in the rural area. As those interfered irreversible rural landscapes have been expanded, the demand for well preserved rural landscapes have been increased. The objectives of this study, thus, is to suggest the mitigations between the land development and conservation of natural landscape. As such, this study examines the recognition of current rural landscape management status through 118 students with two groups of landscape architecture majored (50 people) and non-landscape majored (68). Both group express the negative impression of current rural landscape management system in general and they pointed out the major landscape problems are caused from inappropriate land use. However, in detail those two groups respond differently, for example, the first group selected the damaged landscape is the second cause of the landscape problem, while the other group selected the poorly maintained settlements. Based on the analysis of the survey, this study suggests 3 recommendations in order to improve the sustainable rural landscape as establishing the proper rural land use planning system, building local governments' capacity to actively participate in the rural landscape management, and preparing the landscape management plans considering area distinctive characteristics.
