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 research selected Daegu Metropolitan City representing a combination of natural space and urban space for this case study. To achieve this, a prerequisite was to set up an optimal block size to evaluate landscape diversity of the research site by using a RPR-Area Curve. Further, landscape diversity evaluation was conducted based on land cover map by using FRAGSTATS to analyze spatio-temporal changes. Notably, this research regarded it as the most significant to set forth criteria in order to apply landscape diversity to the development plans of the newtown and outskirt of a city under high pressure development. Results derived from this research are summarized as follows. According to the results derived from establishing the optimal block size, a size about $2km^2$ was analyzed to measure landscape diversity of the research site. Also, according to the results derived from land diversity evaluation based on land cover map, land diversity was highly measured around urban stream such as Nakdong River and Geumho River, and in particular, the value of landscape diversity was measured considerably high around the urban parks. Results derived from analysis on spatio-temporal changes of land diversity demonstrated that a certain level of urban development exerted a positive effect on an increase in land diversity, but consistent urban development lowered a value of landscape diversity. Results derived from regression analysis to set forth the optimal urban space showed that an urban area of a space about $2km^2$ exerted a positive effect at a rate of about 0~43.3% and a negative effect at a rate about 43.3~100%. In conclusion, the results of this research are considered to provide important basic data for future urban and landscape planning. Nonetheless, as only the layout on the 2D plane was analyzed in this research, further research in future is required to complexly consider diverse factors such as height of structure and change in visible real area arising from geographical features.

The Asian cultural landscape is a mirrored ecosystem of great complexity, formed by the interaction of man and nature, coupled with a host of ecological processes. The human dependencies on and environmental adaptation of the bio-organisms and the surrounding landscape constitute the typical cultural landscape. Islands are a good example of a cultural landscape, and each mosaic pattern of marine and coastal ecosystems reflects bio-cultural diversity. Along with land-use patterns, wise use of biological organisms and indigenous knowledge has expanded to islands in the Asia-Pacific region in several ways (sea current and human impact, etc.). Loss in biodiversity and landscape diversity as well as cultural diversity owing to global warming and rapid urbanization are emerging issues for island ecosystems all over the world. In order to sustain the historical coexistence between man and natural systems, we ecologists must continue to search for a holistic solution for academic consilience. In this paper, I present the vision and practical characteristics of island ecology with a view toward the conservation of the traditional landscape and bio-cultural diversities in the seascape.

The materials that are involved in urban landscaping include plants and the associated animals, soil, water, and other environmental elements. And biodiversity is the substantial base for human beings. The conservation of biodiversity is of great importance in the sustainable development of the society and should not be neglected in the development of sustainable urban landscape. The conservation of biodiversity should be included in the urban landscape planning. The conservation of biodiversity should be emphasized in the construction of urban green space. Every possible opportunity should be used to conserve the species diversity, genetic diversity and ecological diversity. The assessment of biodiversity conservation should be introduced into modern landscape planning.

최근 경관훼손 문제에 대응하기 위해 사전 예방적 차원에서 우수한 경관지역을 선정하려는 노력이 이루어지고 있다. 특히 경관 다양성은 경관 구성요소를 평가하기 위한 핵심적인 방법으로 보존가치가 높은 지역의 경관 질을 평가하는데 중요한 기준이 될 수 있다. 따라서 본 연구는 경관을 구성하고 있는 다양한 요소들을 고려한 경관 다양성 평가모형을 설정해 보고, 이를 연구대상지에 적용해 봄으로써 평가모형을 검증하는데 가장 큰 목적을 두었다. 국내 외 문헌 및 연구 자료를 분석한 결과, 경관 다양성 평가모형을 구축하기 위한 지표로서 지형, 식생, 토지이용형태, 특이경관 등 총 4개의 항목이 도출되었다. 지형의 다양성은 지표면 기복정도와 지표면 형태의 다양성을 세부지표로 선정하였으며, 식생의 다양성에서는 식물군락과 층위구조의 다양성을 세부지표로 선정하였다. 각 평가지표의 다양성을 정량적으로 평가하기 위하여 Shannon의 다양성 지수(SHDI)를 응용하였으며, 작성된 각 지표별 유형분류도면에 귀속되는 출현유형과 면적을 Fragstats 4.0에 대입하여 결과값을 산출하였다. 마지막으로 세부지표별 결과값의 표준화 및 합산과정을 거쳐 최종 경관 다양성 지수값을 산출하였다. 이러한 본 연구의 결과는 경관 다양성 평가의 초기 연구 단계로서 방향제시 및 가능성을 모색해 보는데 의의가 있었다. 또한 추후 연구를 통하여 경관 구성요소를 평가하는 핵심 방법으로서, 우수한 경관의 질을 평가하는 중요한 기준으로 활용될 가능성이 있을 것으로 사료된다. 그러나 본 연구에서 제시한 경관 다양성 평가모형은 4가지 지표를 종합적으로 고려하였던바, 우세성을 가지는 세부지표에 대한 고려가 반드시 필요할 것으로 사료된다. 더불어 각 평가지표의 결과값을 표준화하는 과정에서 차후 평가지표별 최대값에 대한 축척된 자료가 보완되어야 할 것으로 사료되며, 다양한 면적과 유형의 사례지들을 분석하여 객관성을 높여 나갈 필요가 있을 것으로 판단된다.

Urban development typically results in many species being confined to small, isolated and degraded habitat fragments. Fragment size and isolation underpin many studies of modified landscape to prevent biodiversity loss. However, habitat characteristics such as vegetation structure and edge effects are less frequently incorporated in planning. The relative influence of biogeographic (e.g. size, isolation) and vegetation parameters on assemblages is poorly understood, but critical for conservation management. In this study, the relative importance of biogeographic and vegetation parameters in explaining the diversity of forest-interior dwelling birds in forest fragments in Chungcheong Province Area. Fragment size and vegetation characteristics were consistently important predictors of bird diversity. Forestinterior bird richness was influenced by fragment size (0.437), wood age (0.332), wood diameter (0.068), and patch shape (-0.079). To preserve bird diversity of Chungcheong Province Area, it is important to consider differing responses of bird diversity to landscape change, move beyond a focus primarily on spatial attributes (size, isolation) to recognize that landscape change also has profound effects on habitat composition and quality. The result is very useful for long-term aspect of biodiversity conservation plan in regional scale.

This study is intended to evaluate the value of functional aspect from the viewpoint of habitat. The indicators that are used in biotope evaluations are various, but most of them use the criteria to evaluate the naturality. This evaluation method cannot appropriately reflect the functional characteristics coming from relation to the surrounding biotope. In this study, the connectivity, cohesion and diversity between individual biotope are quantitatively measured by a landscape index. It is hard to draw the functional value of individual biotopes because the landscape index related to connectivity, cohesion and diversity comes from a landscape having a number of biotopes. The concept of contribution was used to overcome this limitation. The concept of contribution is to quantify how much each individual biotope contributes to the connectivity, cohesion, and diversity in a certain range of landscape by deriving the amount of change in the landscape index according to the presence or absence of each individual biotope. In order to understand the characteristics of evaluation results in functional aspect, this research has done a comparative analysis of the previous research findings in the same target area. According to the result of the research, individual biotopes such as artificial forests, fragmented natural forests, and small planting sites were highly rated.

This study seeks to find an approach tool that allows to consider both ecological and visual aspect in developing an ecological space. Main objective of this study is to develop a planting design method in consideration of correlation between high visual preference and ecological diversity. To this end, an integrated method based on visual design principles and landscape ecological principles was developed first. Then study areas of 20 natural areas and 10 urban areas were selected to survey and analyze visual preference and ecological diversity. The result showed that scale is an element that has the greatest impact on visual preference. In areas with high ecological diversity, scale and connectivity had the biggest impact. In order to have a planting design desirable visually and ecologically based on these factors, it may be divided into following three issues.(1) In oder to increase ecological diversity in areas with strong visual preference, a priority should be given to introduce techniques promoting harmony among dominant species of various scales and other species. At the same time, there should be efforts to secure connectivity. (2) To improve visual preferences in areas with high ecological diversity, close-range, medium-range, and distant landscapes should be ensured by aligning colors and connectivity of various scales with other factors. (3) Also, a target area should be developed into a visually preferred and ecologically sound area by supplementing form and interlocking issues and identifying the spirit of the place. This study offers a way to improve visual preference and promote ecological diversity indeveloping ecological parks for the future. In landscape planning and design, it is important to secure various scales and connectivity as high-priority principles.

Roof greening in a city can contributes to not only providing network opportunities for dispersed greenspace patches but also bringing more greenspaces into a city. In addition, it can help to flooding and microclimate control in the city. Recently, a number of roof greening projects have been introduced, mainly to public buildings and schools. Roof peening need to offers both ecological functions and convenience and satisfaction for urban residents. This study aims to provide directions for improving ecological benefits and visual preference of roof greening. Twelve scene slides were adopted to measure people's visual preference. The survey results show that landscape images can be categorized into naturalness, visual diversity, uniqueness, and spatial flexibility. Physical scenes can be classified into type I mostly greened by plants, type II mixed between convenience facilities and plants, and type III constructed with pond. People show high preferences to type I and type II when visual diversity is high. The results of this study suggest to enhance the visual preference by considering visual diversity when applying the ecological design methods to improve naturalness for roof greening.
