The traditional Japanese agricultural landscape, In which a set of varied land-use patches functions as a sustainable ecosystem landscape unit, not only provides the local people tilth a stable food supply, but also offers a variety of habitats to many species of wildlife. Therefore, remaining natural habitats including those in the traditional agricultural landscape should be maintained whenever possible. In addition, restoration work should be implemented in areas where the natural habitat has been destroyed or severely degraded by human activities. This basic approach to the natural environment is a combination of maintenance and restoration. Types of maintenance and restoration can be classified into three categories according to the countermeasures employed: preservation, conservation and protection types of maintenance, and improvement, reconstruction and creation types of restoration. Four steps are proposed for ecological restoration and maintenance of a target area: exploration, diagnosis, prescription and care. In this process, a model for approaching the goal is important. One of the most important models should center on the traditional agricultural landscape involving a sustainable farming ecosystem. It is necessary to protect traditional landscapes and ecosystems from the degrading impact of urbanization and industrialization, as well as to enhance efforts at restoration.

The purpose of this research is to evaluate five types of eco-village planning in order to introduce a landscape unit concept and theory in Korea. Although they had different backgrounds and motives of eco-villages planning, their common goal is to always maintain ecological planning and design in their villages. As concrete methods of ecological planning, we suggest three fundamental planning theories. 1. The boundary of a plan unit should be a watershed. 2. The survey and analysis of village ecotopes should be done in that defined watershed. 3. These results should be applied in the site and lot planning of eco-villages. These 3 steps should be done in a process and relevantly. In the evaluation of the five eco-village planning types, we found three results. 1. On a viewpoint of watershed, most planners recognized a watershed in survey and planning stages unconsciously. But they did not mention watersheds concretely and did not use this concept in the planning stage. 2. They did not define the concept of ecotope, but most planners recognized land-uses and vegetations of villages and vicinities as ecotopes. Also these could be proper ecotopes, but they did not use these compartment of ecotopes in the planning of ecosystem structure in villages. In addition, they did not deeply survey and analyze the ecotopes of villages and its vicinity. 3. On the viewpoint of sites and lots planning, they did not relevantly use the characteristics of watersheds and ecotopes in sites and lots planning. Therefore, they failed to implement the indigenous lots and subdivisions plan. In the size of lots and sites, they did not seriously consider the carrying capacity of ecosystem. We hope that our suggestion about the establishment of eco-villages planning is a fundamental theoretical framework of ecological planning in future eco-village planning.

The purpose of this study is to understand the classified advantages and weak points of each landscape predictable simulation methods & techniques and to examine the suitability of through or selecting the predictable method suitable for present skill range and on studying the case of resident district unit plan. Therefore, we examined and evaluated through the case study of two sites. The results are as follows. It was very available to process the skill of mapping and picture combining method together at once. But, there was a limitation that is not flexible in the range of error on accuracy, so it was necessary to practically use the equipment and to study the theory. Providing the standard suitable for regional landscape character in each evaluation standard was also necessary.

The purpose of this study is to suggest the landscape potential index for visualizing landscape information in the conservation of hilly landscape in urban fringe. For the visual and quantitative approach to topological landscape assessment, numerical entity data of DEM(digital elevation model) were processed with CAD-based utilities that we developed and were mainly focused on analysis of visibility and visual sensitivity. Some results, with reference in assessing greenbelt area of Eodeung Mt. in Gwangju, proved to be considerable in the landscape assessment of suburban hilly landscapes. 1) Since the viewpoints and viewpoint fields were critical to landscape structure, randomized 194 points(spatially 500m interval) were applied to assessing the generalized visual sensitivity, we called. Because there were similar patterns of distribution comparing to those by 56 points and 18 Points given appropriately, it could be more efficient by a few viewpoints which located widely. 2) Regressional function was derived to represent the relationships between probabilities of visibility frequency and the topological factors(topological dominance, landform complexity and relational aspect) of target field. 3) Visibility scores of each viewpoint were be calculated by summing the visual sensitivity indices within a scene. The scores to the upper part including ridge line have been more representative to overall distributions of visual sensitivities. Also, with sum of deviations of sensitivity indices from each single point's specific index to the weighting values of view points could be estimated rotationally. 4) The deviational distributions of visual sensitivity classes in the topological unit of target field were proved to represent the visual vulnerability of the landform. 5) Landscape potential indices combined with the visual sensitivity and the DGN(degree of green naturality) were proposed as visualized landscape information distributed by topological unit.

본 연구는 가로수 관리의 합리적인 표준품셈 항목 및 적정 단가 설정을 통한 고품질 가로수 관리의 기초자료 제공을 목적으로 하였다. 현재 가로수 관리항목은 가로수 전정을 제외하고, 일반 조경수 품셈을 가로수 관리 품셈으로 활용하고 있다. 또한 한국전력공사에서는 표준전기품셈의 가지치기 항목을 적용하여 표준품셈 대비 강전정의 경우 평균 51%, 약전정의 경우 평균 39% 낮은 단가로 사업을 수행하고 있다. 이는 가로수 관리 품질을 유지하거나 향상시킬 수 없는 한계로 판단되었으며, 가로수 관리의 적정 단가 기준이 필요함을 뜻한다. 가로수 관리 품셈을 개선하기 위해 현업에서 투입되는 비용을 검토할 필요가 있었다. 하지만 국내의 조경 분야 실적공사비에 대한 데이터의 부재로 미국 RSMeans Building Construction Cost Data(RSMeans)의 세부항목을 검토하였다. RSMeans란 1942년부터 누적된 미국의 실적기반 적산방식으로 주로 연방교통부와 각 주정부의 도로국을 중심으로 공사비를 산정하는 데이터베이스이다. RSMeans는 지속적인 신기술 도입과 노동 및 재료비용의 계속된 변경을 반영하기 위해 매해 건설제품과 방법을 찾고 수량화하며, 생산성 비율을 조정하고 있다. 본 연구에서는 국내 조경 관리 방법과 큰 차이가 없는 RSMeans의 세부항목과 현행 인건비 등을 적용하여 실적공사비를 산출하였다. 적용 결과 표준품셈은 실적공사비와 비교하면 가로수 전지의 강전정의 경우 107%로의 양호한 비율이었지만, 약전정은 59%로 과소 설계가 되어 있었다. 또한, 관목 전정은 82%, 제초는 92%, 교목 시비는 87%, 방풍벽 설치는 91% 수준으로 과소 설계되어 있었다. 살수차 관수와 약제 살포는 각각 118%와 124%의 비율로 실적공사비와 비교하면 과대 설계된 부분도 확인하였다. 과소평가된 항목들은 가로수의 특수성으로 도로 안전통제 등으로 인건비 및 장비의 투입비 상승이 주요 원인으로 판단되었다. 향후 표준품셈의 조경 유지 관리항목에 일반 조경수뿐만 아니라 가로수에 관한 항목 추가가 필요하다.

The purpose of this study is to review foreign scenic inventory map for the systematic management of natural scenic resources. Several foreign cases were surveyed and analyzed to apply the scenery inventory map in domestic, such as Visual Resource Management(VRM) from United States Bureau of Land Management, Scenery Management System(SMS) from USDA Forest Service and Visual Landscape Inventory(VLI) from British Columbia Ministry of Forest's, that were already established scenery inventory maps. The results are as follows. First, the characteristic of Korean landscape is quite a different from those of north american's, which is much smaller and more complex in topography and land use. So, it would be difficult to apply foreign system directly and we need more researches to our own system. The multi-stepped landscape unit system is highly recommended. Second, scenic quality could be estimated by the pre-built database, such as land forms, vegetation, hydrology and land uses. Historical and cultural attributes should be complemented. Third, existing scenic integrity could be grasped by scenic damage, landscape alteration caused by human activities and land exfoliation. Also, subjective evaluation method should be supplemented by objective criteria through further detailed studies. Finally, about landscape view conditions, landscape control points should be surveyed and established in advance, and viewing distance, viewing frequency, amount of observers and public interests should be considered.

Recently, as urban landscape is growing in importance, urban landscape planning is being actively performed. for this purpose, classification of the urban landscape is definitely required. Therefore, this research focuses on classifying urban landscape in Daejeon metropolis by dividing the urban land use pattern. This results are as follows. 1. Urban land use pattern is divided into 20 classes. The residential, commercial and industrial areas, the old market and the bus terminal are evaluated negatively, whereas the areas of school, water reservoir, neighborhood park and train station are appreciated as being positive in landscape characters. 2. As a result of a cluster analysis, urban landscape has five different landscape types. These are: landscapes of medium diversity lacking green area, landscapes of high diversity lacking green area, landscapes rich in green area and with medium diversity, landscapes rich in green area and with high diversity, and landscapes rich in green area and with low diversity. 3. In landscape characters of beauty and harmony, landscapes rich in green area and with medium diversity are more positively evaluated than those rich in green area and with low diversity. This point should be taken into account for planning the urban landscape.

This study quantified annual net carbon uptake by urban landscape trees and provided equations to estimate it for Ginkgo biloba, platanus occidentalis, Zelkova serrata and Acer palmatum, based on measurement of exchange rate for two years growing seasons from Sep., 1995 to Aug., 1997. The carbon uptake was significantly influenced by photosynthetic capacity, photon flux density and pruning. Ginkgo biloba showed the highest rate of net CO\sub 2\ uptake per unit leaf area and Acer palmatum did the lowest rate among those species. A tree shaded by adjacent building over the growing seasons showed net CO\sub2\ uptake per unit leaf area much lower than another tree of the same species less shaded. Annual net carbon uptake per tree was 19kg for Zelkova serrata, but only 1 kg for Ginkgo biloba and Platanus occidentalis with crown volume dwarfed from pruning. One Zekoval serrata tree annually offset carbon emission from consumption of about 32 liter of gasoline or 83 kWh of electricity. Strategies to improve CO\sub 2\ uptake by urban landscape trees include planting of species with high potosynthetic capacity, sunlight-guaranteed road and building layout for street trees, planting of shade-tolerant species in the north of buildings, and relocation of utility lines to underground and minimized pruning.

This research was initiated to investigate the revegetation characteristics under seedling types of native woody plants on a disturbed slope. 4 different seedling types of woody plants (control, unit seedling plot, nature seedling plot, pot seedling plot) with the same woody plants (Rhus chinensis Mill, Albizzia julibrissin Duraz., Quercus acutissima Carr., Pinus densiflora S. et Z.) were treated with 3 replications on the experimental disturbed slope. Data such as the died number of native woody plants, growth height and visual quality were analyzed. The died number of plants were high in unit seedling plot when compared to the rest plots of seedling types. From the standpoint of died plant species, the died number were high in Rhus chinensis and Albizzia julibrissin whereas the died number were low in Quercus acutissima and Pinus densiflora. That's because we used 1-year old seedlings of Rhus chinensis and Albizzia julibrissin and 3-year old seedling Quercus acutissima and Pinus densiflora. This result indicated that the died reason of native woody seedling was not species but seedling age. Both growth height and visual quality were ranked first in the pot seedling plot, second in the nature seedling plot, third in the unit seedling plot, and last in the control plot, respectively. However, the difference of both growth height and visual quality in each seedling plot was not observed on the 11 months after planting. Especially, the main reason of low rooting and growth value in the unit seedling plot was due to wooven fabric outer crust of pot that obstruct seedling rooting into the soil. We concluded that pot seedling of native woody plants was effective in the viewpoint of the ecological disturbed slope revegetation.
