Humans are provided with a wide range of public benefits from ecosystems and agricultural ecosystems. But the establishment of the horticulture complex is a space that hampers the public ecosystem. Therefore, we have evaluated the creating landscape function of the horticulture complex and found improvement. A total of 20 landscape slides were used for the study. Korea-paddy field, Korea-vinyl greenhouse, Korea-glass greenhouse, Japan-vinyl greenhouse and Netherlands-glass greenhouse were selected as 4 slides. The evaluation used the AHP method and 10 adjectives Likert which compares 20 landscape slides. Four Korea-paddy fields were rated highly positive images. All 10 adjectives can be selected as representative images of production scenes. In most adjectives, four scenes of KVG1, KVG2, KVG3 and KVG4, which are the Korea-greenhouse scenes, were evaluated as negative images. Netherlands and Korea-glass greenhouse scenes and Japan-vinyl greenhouse scenes were generally positive images. In conclusion, it is confirmed that glass greenhouse scenery is higher than vinyl greenhouse scenery. And Japan and Netherlands scenery are higher and better than Korea. Therefore, JVG1 in Japan and NGG3 in the Netherlands were proposed to be set as landscape improvement targets.

The importance of the green space in urban area has been increasing. There are the increasing needs of creation and sustainable management of urban forest. In order to satisfy the need, it is necessary to set indicators for sustainable urban forest. With this regard, this study is to derive the indicators for evaluation of the urban forest through literature reviews, experts opinion, and field survey. The results of the study, the indicators consist of the ecological healthiness, socio-cultural function, and scenic beauty. The ecological healthiness includes stability and naturality (e.g. area, native species, connectivity etc.). The socio-cultural function contain improvement of living environment, stable emotion, community, and environmental education. The scenic beauty includes environmental-friendly facilities, maintenance of urban forest. The indicators have high feasibility to create and manage the urban forest through evaluating urban forest in practical. This indicators are useful to guide to develop urban forest and park.

This study aims to discriminate differences in natural landscapes between the Cairngorms National Park in Scotland and the Jirisan National Park in Korea, using functions of content-based image retrieval such as texture, shape, and color. Digital photographs of each National Park were taken and selected. The low-level functions of photographic images were reduced to orthogonally rotated five factors. Based on the reduced factors, a linear decision boundary was obtained between Cairngorms landscapes and Jirisan landscapes. As a result, the discriminant function significantly delineated two groups, resulting in $x^2=63.40$ with df=5(p<0.001). Both the eigenvalue 2.417 and the value of wilks' lambda 0.29 supported that the most proportion of total variability came from the differences between the means of discriminant function of groups. It was estimated that four independent variables explained about 70.7% of total variance of dependent variable. The variable with the largest effect on landscapes was far region-related factor(r=1.07), followed by near region-related factor (r=0.90). A total of 90.7% of cross-validated grouped cases were correctly classified. It was interpreted that far distant regions, as well as near distant regions, had sufficient discrimination power for landscape classification between the Cairngorms National Park and the Jirisan National Park, so that landscape identity of the National Park over cultures was revealed by skylines in a most effective way. Relatively fewer factors making visual landscapes were effectively used to classify natural landscapes of the National Parks which had different semantics.

As differences in the impact of each species on a spatial scale occur, analysis at the landscape scale is necessary to evaluate the impact of a development project. In previous studies, the Incidence Function Model (IFM) based on meta population theory was used to analyze the impact of species on the environment that changes according to urban development. However, since the model was required at least 10 occupied areas, it is difficult to use it for species that are difficult to monitor such as endangered species. Therefore, we proposed the Incidence Function Model (IFM) using species distribution model to fill the species data. In addition, we reviewed whether the developed model can be used in environmental impact assessment. As a result of the analysis, the minimum occupancy of Prionailurus bengalensis on urban development decreased to 56.5% and the possibility of survival to 28.7%. We confirmed that It rapidly decreased from the reference points of 230 and 70habitats through analysis of the meta-population capacity according to the decrease in the number of habitats. These results can be assessing the environment impact of each species on habitat loss. And it can support decision-making on the minimum number and area of habitat for species protection. This study is expected to be used as basic data for environment impact assessment on before and after development projects and mitigation measures plans, thereby increasing the effectiveness of reduction plans.

Indoor thermal environment and energy consumption of buildings are preferentially affected by the microclimate around buildings. It is the first method to improve energy conservation effect of buildings and the ways to utilize natural energy for the comfortable residential environment that the difference between the microclimate condition and the indoor thermal condition is made in minimum as far as possible. There are many factors to control and minimize the difference, but landscape element is the major one among the factors. In this respect, the report analyzes landscape elements and their function to control microclimate and presents basic data for the desirable landscape planning mehtods to improve energy conservation effect of buildings and to attain the comfortable residential environment.

The fundamental concept of shared street is integration of traffic and pedestrian activity as a positive principle for street planning. Shared streets have been very successful in several countries in terms of reductions in traffic accidents, increased social interaction and children's play, and a high degree of satisfaction by the residents. This paper proposes the concept of shared street to solve traffic problem without reorganizing traditional street structure and without disturbing traditional function of street as a living space for residents. And this study examines detail concepts and techniques of the shared street and applies them to a pedestrian oriented streetscape design of "Ducksugung-Gil," Seoul, which was one of the most important streets in Korean modernization history.n history.

This paper describes the ecological structure and function of riparian zone, and their historical changes with land-use. The riparian zone consists of valley floor landform and riparian vegetation. The functions discussed are attenuation of sunlight energy, input of leaves and needles, contribution of woody debris to streams, and retention of flowing material out of transport. These primary functions directly or indirectly influence water and sediment qualities of streams, bars and floodplains, and thereby aquatic biota. Temporal changes in a hydrological system and riparian ecosystem were examined with reference to land-use conversin in order to understand the linkages between these two systems in Toikanbetsu River. The influences of channelization and land-use on discharge of suspended sediment and wetland vegetation was also investigated in Kushiro Marsh. These two examples suggested that the ecological functions of riparian zone have been degraded as flood control and reclamation works have expanded in the past twenty years The author proposes river restoration planning by preserving or creating landscape elements based on the concepts of sustaining physical and ecological linkages.

The purpose of this study was to propose management strategies through aesthetic landscape assessments for landscape units in the Han River riparian(HRR) area. First, this research reclassified the HRR into "natural," "artificial," "agricultural," and mixed landscape types and selected 37 representative case areas(about $1km{\times}1km$). This study found 71 landscape units in consideration of topography and land surface classification. Landscape assessment consisted of landscape quality and landscape integration assessment. The criteria for assessing landscape quality were "naturalness," "interest," "uniqueness," and "landscape function." "Landscape quality" was ranked into five grades using a matrix. The landscape integration assessment consisted of an inner integration assessment in each landscape unit and outer integration assessment among landscape units. As a result of the field study, case sites were found to have 4,288 landscape units and an area of $42.8km^2$. The forest area was found to have the most space with $11,580,905m^2$(27.1%), while the wet lands had just $52,348m^2$(0.1%). In the landscape quality assessment, about 30.5% of the total area consisted of landscape units that scored highest in "naturalness". In the landscape integration assessment, about 39.3% of the total area consisted of landscape units which scored highest in "integration", denoting visual interrelation and harmony. The existence of disparities in landscape quality in accordance with the form of the landscaping was determined using a Oneway ANOVA, with "naturalistic" landscaping scoring the highest and "artificial" landscaping scoring lowest. This study may contribute to making the HRR area a more ecologically sound and visually attractive landscape space. It is recommended that the aesthetical and ecological value of the landscape unit should be assessed simultaneously in the future.

This study is focused on finding out the character of urban recreation forest and investigating facilities regulations of forest resources around urban areas to meet future recreation needs. The method of this study is to compare urban recreation forests with similar facilities like urban parks and natural recreation forests. By this way, this study not only identifies the characteristics of urban recreation forest as emerging recreational facility, but also outputs regulations that can be adapted to real environment. Urban recreation forest is defined as follows: It has forest with good natural landscape and easy access. It makes emotion rich and its function is focused on outdoor recreation nature education, and experiences for family group mainly within a day or on weekends. This study suggests that the minimal area of urban recreation forest should be over 100,000$m^2$, with a facility ratio less than 20%. Building coverage should be less than 7% when the urban recreation forest is under 300,000$m^2$, less than 5％ when 300,000∼500,000$m^2$, and less than 3％ when over 500,000$m^2$ The limits of building height is 3 stories, or under 12m. This study finds out the character, the needs of urban recreation and the criterion for project feasibility. significance of the result is supplying theoretical basement on related regulation. Based on the results, further study will establish landscape management method and legislation & application in a detailed examination.
