  • To designate rural landscape spatially, land use and topographic features for 383 of "Ri"s or "Dong", which is a basic administrative unit in Korea, were analyzed using GIS application. We have categorized rural landscape into three types such as agricultural, natural and urban landscape by land use. On the basis of spatial landscape pattern, rural area could be classified into 6 groups of Mountainous area (MA), Mountainous village area (MV), Developing mountainous village area (DM), Plain agricultural area (PA), Developing plain village area (DP) and Urbanized area (UA) according to the ratios of land for agricultural and urban use as the criteria. In MA, the ratio of upland area including orchard was slightly larger than that of paddy, while that of paddy was about 1.5 times larger than upland in other groups. Forested area was distributed more than two-thirds among natural landscape area in MA, MV and DM. In plain types (PA and DP), the ratio of irrigated paddy was extremely larger than partially irrigated paddy and the ratio of water body area among the natural landscape area was two times as large as that of forested area. The ratio of land for industrial and livestock facilities among urban landscape area were 20% or more in MV, DM and DP, and it means that these facilities are mainly distributed in the developing ru ral area where residents and industry are closely related each other. According to the relative ratio of sloped land of 6 categorized areas, the MA area have lots of land with E and F slopes and MV and DM have all grades of sloped land evenly distributed in relative to other types of rural landscape. It has been showed that PA, DP and UA occupied more than two-thirds of land with A or B slope. In case of the analysis of topological distribution in 6 types of rural landscape, there were overwhelmingly lager highland areas in MA. Conclusively, we have confirmed that 6 types of rural landscape classified by land use pattern in 3 categorized areas such as agricultural, natural and urban landscape area would be useful for the management of rural area. For development of sustainable agriculture and the preservation of rural amenity, proper management ways should be properly applied according to rural landscape patterns.

  • As you know, there are a lot of our own traditional folk village exist in Korea, our country. Most people just know is that Korean traditional village is just happen make it and just continuously keeping this times type. But this village is not just make it but made by serious scientific sources such as, rule of locating streets. There are three very important reasons why I research this topic for my research paper. The first important reason is that Korean traditional villages have the pattern of human moving line system in accordance with hyung-kug. Hangae village that located on inclined ground named baesanimsu has the longer human moving line than Hanbam village that located on level ground. The second important reason is that Korean traditional villages have the smaller human moving line of the length and the amplitude as long as going inside villages. But the unit of the amplitude is the larger. Hanae and Hanbam village is the same pattern. The third important reason is that Korean traditional villages have the smaller human moving line of the length and the amplitude as long as having the larger gradient. Hangae and hanbam village is the same pattern. And Hanbam village hast he bigger human moving line of the length, the amplitude and the unit of the amplitude. In conclusion, by these three important big reasons, Korean traditional village is built by scientific sources. And now we can say that our old generation was very unbelievable genius. By these reasons we have to make sure when we make another city town and farm village planning. The meaning of making sure is that a person who have responsibility for making city have to make plan by scientific sources. It has to be not only theoretical but also think about real human life. It also fit on our traditional.

  • This study aims to establish the identity of traditional Korean gardens and develop a universal way for overseas Koreans and foreigners to have an appropriate understanding of traditional Korean gardens, as part of efforts to distribute and promote the overseas establishment of traditional Korean gardens. The focus of this study is on developing planning and design guidelines to ensure that traditional Korean gardens have individuality when they are established overseas and on establishing directional rules for planners. Although traditional Korean gardens may vary in form according to their purposes and spatial scales, the most important thing is that they should incorporate emotions that are well-matched with Korean landscapes and that their design language should be easily recognizable and understandable to everyone. The basic spatial types of traditional Korean gardens for overseas establishment, which are presented in this study, include the exhibition(fair) type, the garden type and the park type. These basic types serve as prototypes that correspond to the purposes of the gardens. In consideration of the spatial scale, the exhibition(fair) type is set as the minimum unit for composition, and suggested basic facilities include trees, a well, a pond and an island in the pond, flower beds and fences. The results of this study have significance as basic information for planning and designing traditional Korean gardens for overseas establishment.

  • The shape of land surface work as a cradle for various environmental processes and human activities. As spatially distributed process modelings become increasing important in current research communities, a classification system that delineates land surface into characteristic geomorphological units is a pre-requisite for sustainable land use planning and management. Existing classification systems are either morphometric or generic, which have limitations to characterize continuous ecological processes over the landscape. A new classification system was developed to delineate the land surface into different geomorphological units from Digital Elevation Models(DEMs). This model assumes that there are pedo-geomorphological units in which distinct sets of hydrological, pedological, and consequent ecological processes occur. The classification system first divides the whole landsurface into eight soil-landscape units. Possible energy and material nows over the land surface were interpreted using a continuity equation of mass flow along the hillslope, and subsequently implemented in terrain analysis procedures. The developed models were tested at a 12$\textrm{km}^2$ area in Yangpyeong-gun, Kyeongi-do, Korea. The method proposed effectively delineates land surface into distinct pedo-geomorphological units, which identify the geomorphological characteristics over a large area at a low cost. The delineated landscape units mal provide a basic information for natural resource survey and environmental modeling practices.

  • This study was carried out to provide a basic data for preservation of Pinus desiflora forest as cultural landscape forest by analyzing characteristics of plant community of P. desiflora forest in Geumjeongsan(mountatin) in Busan city. In order to analyze plant community of P. densiflora in Geumjeongsan, we set up 10 study plots inside and 8 plots outside of Geumjeongsansung(mountain fortress, hereinafter 'Sansung')(unit area: $400m^2$), a total of 18 plots. TWINSPAN analysis divided these 18 study plots into 6 communities which are Querqus serrata-P. desiflora community, P. desiflora community, P. desiflora-Q. serrata community, P. thunbergii-P. densiflora community, P. densiflora-P. thubergii-Q. acutissima community, and P. densiflora-Platycarya strobilacea community. Importance Percentage (I.P.) of each area and DBH class distribution of main species showed that P. densiflora community would succeed to Q. serrata community or C. tschonoskii community. Analysis on tree age found out that communities in the Sansung were 32~37 years old and those outside the Sansung were 44~57 years old. Shannon's species diversity index ranged from 0.4826 to 1.2499. Regarding correlation between species, P. densiflora had negative correlation with Styrax japonica. Based on abovementioned result we expected ecological succession from P. densiflora community to Q. serrata community inside of the Sansung. Outside the Sansung, succession from P. densiflora-P. thunbergii community to C. tschonoskii-Q. serrata community was expected. In order to manage P. densiflora forest as cultural landscape forest, Q. spp in the understory and shrub layer and deciduous broad-leaved arboreal trees should be managed. Tree crown management of deciduous broad-leaved trees in competition with P. desiflora, is also required.

  • This study aims to examine and research the characteristics of apartment landscape at the street from a view that apartments are the major element of a cityscape and many apartments form a street today. Then, the subjects of this study were three sections consisting of streets in Namak New Town and the results were as follows. A streetscape is necessary to have identity under the unity(context) of parts which orient to "one as a whole". However, the subject apartments were not united(contextual) in layouts, roofs, and walls, whereas their facades appeared too united(contextual). Accordingly, to make a united(contextual) streetscape, the wall located in a boundary(a buffer zone) with public space which consists of a streetscape, building layout, building height, and roof forms need a design guideline which can have unity as a whole to connect with architectural design. On the other hand, the facade which was found too uniform should have a more active design guideline to elicit identity at unity.

  • This study aimed to re-establish the conservation area reflecting landscape ecological value through scenario program, targeting Odaesan National Park. The basic data were mapped in watershed planning units, which were set considering topographical and ecological values. The framework of Marxan with Zones, using an indexation process, was using the mapped indicators. Each best solution according to the scenarios was assessed through sensitivity analysis, and a final solution was selected among the best solutions, considering criteria including area ratio of conservation area and grouping. Lastly, the final solution was verified in the overlap analysis with recent zonation. As a result, through the framework of Marxan with Zones, the best solution of scenario 1, which was set by the highest conservation criteria was selected as the final solution, and the area ratio of conservation area and grouping was excellent. As for the overlap analysis, the suggested conservation area was improved compared to recent zonation in terms of the area ratio (39.4%), biotope grade I (35.6%) and the distribution points (7 places) of legally protected species.

  • The objective of this study is to estimate the cost and benefits of street trees for their planting types, specifically, single row, single row+bottom, double row, double row+bottom. Different planting types are compared and analyzed by using Net Present Value (NPV) and benefit-cost ratio (BCR). Existing data are collected from the literature reviews for the use of meta-analysis method for estimating cost and benefit. The elements for analyzing costs are management and planting costs, and benefits are air purification, energy saving and landscape view. The discount rate is applied at a minimum of 3% and a maximum of 5.5%. The unit used in this calculation is km/year. The result shows that the net benefit is highest in double row, followed by single row, double row+bottom, and single row+bottom. The BCR is the highest in double row, followed by single row, double row+bottom, and single row+bottom. The BCR reaches the break-even point from 9 to 17 years depending on the planting types.

  • This study measured transpiration rate of urban trees and albedos of urban surfaces, and examined the function of microclimate amelioration by urban greenspace. Transpiration rates of trees were highest in July and August of growing months. Transpiration per unit leaf area for the two months was 300-350 g/$m^2$/h for Platanus occidentalis, 210-270 g/$m^2$/h for Ginkgo biloba and Zelkova serrata, and 130-140 g/$m^2$/h for Acer palmatum. Surface albedos were 0.09 for asphalt paving and 0.68 for white wall, which reveals that light-colored surfaces are better than dark-colored ones to lower the heat build-up. Due to lack of evapotranspiration, concrete surfaces were, at t midafternoon maximum, 8$^{\circ}C$ hotter than grass ones, though the albedo of concrete paving was higher thant that of grass and trees. Summer air temperatures at places with 12% and 22% cover of woody plants were, respectively, 0.6$^{\circ}C$ and 1.4$^{\circ}C$ cooler than a place with no vegetation. To mitigate the impacts of urban heat islands, required are minimization of hard surfaces, light-coloring for building surfaces, and greenspace enlargement including more plantings.
