We need to use aesthetic landscape assessment(ALA) as the means of riparian buffer zone(RBZ) management. This study verified the political validity of designation policy of RBZ and land purchase policy. The purpose of this study was to propose RBZ landscape management strategies through ALA of RBZ in Gyeongan Stream for the better attractive and healthy riparian landscapes. The natural type landscape units(LUs) covered 40.9% of the entire area and the cultivated land type LUs covered 20.58%. Landscape assessment consisted of landscape quality and landscape integration assessment. The criteria for assessing landscape quality(LQ) were naturalness, interest, uniqueness, and landscape function. LQ was ranked into five grades using a matrix. The landscape integration assessment consisted of an inner integration assessment in each LU and outer integration assessment among LUs. To review the propriety of designating the riparian area and the riparian ecological belt, differences in ecological appraisal and aesthetic valuation were reviewed through a t-test, Oneway ANOVA, and logistic analysis. The results of ALA, 29.15% of the entire area scored at grade 1 in LQ, while 31.95% scored at grade 5, indicating that grade 5 areas occupied a high share. Surveyed areas were divided into designated RBZ and undesignated RBZ. Results indicated that designated RBZ scored grade 1 in LQ took up 33.2% of the total, significantly higher than the 23.3% taken up by undesignated RBZ. When examined according to buffer distance, grade 1 areas within 50m took up 50.2% of the total area, lower than the 32.7% at buffer distances of 500m-1km. Results indicated a 1% statistically significant difference. Accordingly, analysis was undertaken for the expansion of designation of the riparian area and the selection of appropriate land for formation of a riparian ecological belt, and was designated at priority 1 and 2 for land purchase. This study can also contribute to the formation of a riverine eco-belt through discovery of design factors for upgrading the ecology, aesthetics, and landscape of the riparian area and application in determining land purchase priorities.

The city means not only a geographical area as a role of the spatial boundary, but also a socio-economic place to communicate with each part. It requires various functions to get the income and activities. But city has a limitation of a available land to provide the required function and a sufficient space to supply the activity. Therefore, the development trend of city has not been to spread to the horizontal area any more and considered the vertical area. In addition, various functions put into a massive building because many people want to solve the daily requirements without spending time and cost. In this paper, it aimed at classifying the mixed-use building into function, circulation, relation between the public and private space and the building shape to provide the design information according to the development constraints such as land area, functional limitation, accessibility, etc. The classification of the mixed-use buildings is divided into four areas. The data are collected with foreign countries in Japan, Europe and US.

There are two ways of reducing air pollution. One is the approach of the pollutant source control and the other one is the traffic demand decreasing approach. This study is focusing on the approach of land use planning and optimal location of urban facilities because those are the basic cause to generate transportation demands. So, the purpose of this study would be to analyze the changes of NOx and CO distribution on environmental air by functional hierarchy of urban roads and to make evaluation model of 'Transportation-Land Use -Air Pollution'. It will contribute to improve the air pollution level at same actual traffic generation according to different location.

In the estimation of grid type area source emissions, the factors by which emissions are distributed spatially must be considered comprehensively. The estimation process can be approached systematically by connecting the emission activity of air pollutants with land use pattern and the various impacts can be taken into account in the process by using such area information as land use, population, distribution of households, types of housing units, fuel consumption and so on. The estimation procedure was computerized in order to calculate area source emissions by grid information system. This computerization helped to augment effectiveness and efficiency not only by managing enormous data but also by performing diverse functions.

The concept of vertical living has been hailed as a solution to control fast growth and urbanization of cities worldwide. As super tall residential projects become more common and sustainability considerations become more necessary, their efficiency has been called into question. How do vertical residential developments compare with suburban homes? What are the environmental advantages and disadvantages of vertical communities? Is there a middle ground? We present the results from an AS+GG study that compares the environmental performance of different housing typologies ranging from a 215 supertall building to single family residences, including several scales in between. Our samples comprise 2,000 residential units per type and include the infrastructure needed to support them. We analyzed land use, energy use, and lifecycle carbon emissions for each typology. The results show that different typologies perform better depending on the parameter being assessed. We discuss these findings; assess overall performance, and present conclusions.

This study was aimed to establish biotop unit of the mixed rural city for the method and process of the biotop mapping system. Survey site was Maejuri of Seunghwan(158ha), Gisanri of Mokchon(132ha) and Namkwanri, Pungsemeon(214ha). So the main process was divided by 4 schemes such as Biosphere, Geosphere, Antrosphere and Evaluation. Also the GIS(geographic information system) was used to make the database of the biotop and biotop complex, analyze the cross-combinations and analyze the characters of the biotop. Biotop mapping system had 5 steps which were proceeded with research goals, constructing the spatial database and attribute database, classifying the 3 types of biotop such as tree/shrub biotop, grass biotop and wetland biotop, cross-analyzing 3 biotop types with land use, habitat characters, relief characters and danger/disturbance elements and evaluating the 3 types of biotop. The results of applicating the biotop mapping system on the research site as followings : The distributions of the land uses in Maejuri, Seunghwan eup in Chonan city were recorded by forest(29.8%), orchard(14.1%) and landscaping around building site(9.0%). Gisanri, Mokchonmeon were composed of forest(64.5%), farm(12.8%) and Namkwanri, Pungsemeon were concentrated rice field(39.6%), dwell district(22.4%). The Tree/Shrub biotop type was reclassed by the forest type, natural and artificial decidous type with natural coniferous. The Grass biotop type was reclassed by the wild grassland type, garden type and peddy field with wild grassland. The distributions of the wet land were pointed high at the wet land type with reed marsh and edge vegetation around wet land in reservoir and river. The evaluation of the mapped bitopes was completed to the following aspect, "amenity" and "environmental education". A high value of 7.13%(1 class) was shown Maejuri, Seunghwan eup. The regions which were studied synthetically are divided to three parts ; the area where have nature and art mixed(Seunghwan), the area which is more artificial because people inhabit there for a long time(Pungsemeon) and the area that ecological environment is threatened by development pressure(Mokchonmeon). Therefore, ecological restoration plan which depends on specific property of the regions should be established. Also the interdisplinary researches were needed to develop the BMS(Biotop Mapping System) in Korea because of the differences with Germany, England's ecological habitat conditions.

The aim of this study is to apply and crossvalidate a spatial logistic multiple-regression model at Boun, Korea, using a Geographic Information System (GIS). Landslide locations in the Boun area were identified by interpretation of aerial photographs and field surveys. Maps of the topography, soil type, forest cover, geology, and land-use were constructed from a spatial database. The factors that influence landslide occurrence, such as slope, aspect, and curvature of topography, were calculated from the topographic database. Texture, material, drainage, and effective soil thickness were extracted from the soil database, and type, diameter, and density of forest were extracted from the forest database. Lithology was extracted from the geological database and land-use was classified from the Landsat TM image satellite image. Landslide susceptibility was analyzed using landslide-occurrence factors by logistic multiple-regression methods. For validation and cross-validation, the result of the analysis was applied both to the study area, Boun, and another area, Youngin, Korea. The validation and cross-validation results showed satisfactory agreement between the susceptibility map and the existing data with respect to landslide locations. The GIS was used to analyze the vast amount of data efficiently, and statistical programs were used to maintain specificity and accuracy.
