우리나라에서의 대설피해는 지역별로 차이가 있으며, 그와 같은 지역별 강설 특성을 파악하기 위해서는 지역별 과거의 기상현상 및 강설자료의 수집·분석이 수반되어야 한다. 또한 대설로 인한 피해특성을 이해하기 위해서는 지역별 강설 특성 뿐만 아니라 지역별 대설피해의 예방·대응체계의 조사 및 분석, 대설 피해규모의 조사 및 분석이 추가되어야 한다. 그 중에서 본 연구는 대설에 의한 지역별 피해현황의 공간적 분포를 살펴보았으며, 이를 위해 장기간의 분석기간과 분석자료를 활용, 시·공간적 변화추이를 살펴보았다. 분석결과, 대설에 의한 이재민 피해는 충청도와 서해안 부근에서 높게 나타났으며, 대설에 의한 인명피해(사망)는 매우 적은 것으로 나타났다. 또한 이재민·인명피해 및 재산피해 등을 모두 포함한 총피해액은 경기지역과 충청도, 전라도 해안지역에서 크게 나타났으며, 전반적으로 충청·전라도지역을 포함한 서해안 지역에서 대설에 의한 피해가 상당히 발생되고 있는 것으로 나타났다.

The aim of this study is to analyze the green-tourism centrality considering spatial interaction using Gravity Model and social network method. The degree centrality and prestige centrality were applied as green-tourism centrality index. The rural amenity resources and human resources were counted as attraction factors, and a distance among villages was used as friction factor in gravity model. The weights of rural tourism amenity resources were calculated using the analytic hierarchy process(AHP) method and applied to evaluate green-tourism potentiality. The distance was measured with the shortest path among villages using geographic information system(GIS) network analysis. The spatial interaction from gravity model were employed as link weights between nodal points; a pair villages. Using the spatial interaction, the degree-centrality and prestige-centrality indices were calculated by social network analysis and demonstrated possibility of developing integrated green-tourism region centered on high centrality villages.

In this study, we implemented landslide distribution of Jeju Island using ANN and GIS, respectively. To do this, we first get the counter line from 1:2,5000 digital map and use this counter line to make the DEM. for the evaluate the land slide susceptibility. Next, we abstracted slop map and aspect map from the DEM and get the land use map using ISODATA classification method from Landsat 7 images. In the computation processes of landslide analysis, we make the class to the soil map, tree diameter map, Isohyet map, geological map and so on. Finally, we applied the ANN method to the landslide one and calculated its weighted values. GIS results can be calculated by using Acrview program and produced Jeju landslide susceptibility map by usign Weighted Overlay method. Based on our results, we found the relatively weak points of landslide ware concentrated to the top of Halla mountains.

The purpose of this study is to analyze the locational characteristics of arboretums using GIS- based spatial analysis method in korea, focusing on the utilization of arboretums. For this analysis, two national arboretums, fifteen public arboretums, twenty four private arboretums, and six arboretums managed by an educational establishment were selected to collect data for the information on spatial location analysis. The procedure of this study has three steps. First, as main factors to affect the locational characteristics of arboretums, the accessibility of road, the proximity of urban and their environs are chosen, and the spatial influence of arboretum is determined by population dwelling near to arboretum. Second, the thematic map data for this analysis is generated using distance measurement method and graded through scoring method. Finally, the relationship between locational factor score of arboretum and the number of visitors was investigated to validate feasibility of the spatial locational analysis using GIS. As a preliminary research, this study shows that spatial locational characteristics of arboretums can be evaluated objectively and quantitatively using GIS (Geographic Information System) and the result of this study can provide fundamental information for developing and managing an arboretum.

Starting from Jan. 1, 2006, pursuant to Article 28 of the Natural Environment Conversation Act for development acts with natural Landscape as a subject, the Consultation System on the Effects of Natural Landscape has been put into force in order to, in advance, analyze and predict the effects of natural Landscape according to the implementation of various development plans and development projects and also minimize adverse effects by preparing plans to reduce the effects. The consultation on the effects of natural Landscape is based on the objective and scientific approaches of data with Landscape to minimizing the effects of natural Landscape by developments with the preservation, restoration, outlook and harmonization as basic principles, and looking into the review of natural Landscape damage and harmonization of the site to be developed. For more objectively analyzing the visual effects of natural Landscape according to development acts, the purpose of this study is to provide basic materials of continued Landscape management plans in the planning stage of development plans and after the completion of developments by analyzing the sensitivity of Landscape and deriving areas, whose Landscape will be damaged, mainly focusing on the area of visibility using GIS.

The purpose of the study was to construct a forecast system of flood inundation area at natural stream channels. The study built the system to interpret the flood inundation area in four stages ; constructing topography data around the stream channel, interpreting flood discharge, interpreting flood elevation in the stream channel, and interpreting the flood inundation and mapping. According to the result of the analysis, as for the characteristic of flood inundation around the area within the purview of this study, although there were areas where flood inundation over a bank caused a flooded area, the failure of the internal drainage in the ground lower than flood elevation caused more serious problems. Rather than the existing method where only the estimated flood elevation data is used based on the hydrographical stream channel trace model(such as the HEC-RAS model) to establish the flood inundation area, if the procedure introduced in this study was applied to interpret the floodplain, actual flood inundation area could be visibly confirmed.

In this study, a model was developed to analyze the capacity and the total price of the agricultural products marketing between nations through the estimation of the production and consumption amount of the agricultural products in each nation and the analysis of the price and transport cost to each nation. The method which can contribute to the agricultural policy decision support was devised. The main concept of the method is to compute the potential import-export amount and total cost among the nations. In the application, wheat was selected to evaluate the model. The application results showed that the model could analyzed the unit consumption and storage amount per capital of each nation and the price and transport cost per unit weight from each export nation, provided the policy decision maker with the basic data analyzed by GIS.

This study is to establish a planning methodology for rural area development with land suitability classification. Land suitability classification was carried out by introducing Geographic Information System. The planning methodology was applied to Sunheung district located in Youngpoong county, Kyongbuk Province, Korea. Land suitability classification by the GIS showed that only 29 % of present agricultural land were higher than class 2 and 71 % were in bad condition for agricultural land. Especially, 22.2 % of agricultural land were under class 5 as the lowest level and 265.2 ha of forest were possible to develop as an agricultural land. It was proved that GIS may be a powerful tool in rural planning process. In addition, it is thought that GIS can be applied to the fields of agricultural land management system in many ways.
