In this study a landscape evaluation was carried out for the submission of a natural landscape conservation plan with the intention to prevent damage to natural landscapes through incautious exploitation. In the case of Korean landscape evaluation, in fact, only the aesthetic value of the landscape is evaluated as related to development projects but the ecological relevance of the landscape cannot be estimated by evaluating only the aesthetic. For that reason, this study performed a landscape evaluation, including the sensitivity limit of visible scenery and the diversity of ecological scenery. For the intention of landscape evaluation in the designation of an essential conservation area and for devising a plan related to this area, a GIS applied to Ian McHarg's map overlay method was used and both the ecological landscape diversity and the aesthetic value of the landscape was surveyed using this map overlay method. A region can be analyzed in relation to the needs for concentration of management in influence analysis of landscape effect elements. 본 연구에서는 무분별한 개발로 인한 자연경관훼손의 예방을 목적으로 자연경관보존방안을 제정하기 위한 경관평가를 수행하였다. 우리나라에서의 경관평가는 개발계획에 따른 시각경관만을 평가하고 있는 현실이며, 경관의 생태적 본질까지 동시에 평가하지는 못하고 있는 실정이어서 이에 대한 대책이 요구되고 있다. 본 연구에서는 이를 위해 시각경관민감도와 생태경관다양성을 요소로 하는 경관평가를 진행하였다. 경관평가의 목적은 실질적인 보존지역을 설정하고 그에 따른 계획을 수립하기 위함이기 때문에 이앤 맥하그(Ian McHarg)의 도면중첩법을 적용한 지리정보시스템(Geographic Information System: GIS)를 활용하였으며, 생태경관다양도와 시각경관민감도를 측정하여 중첩분석하였다. 또한, 경관영향요소의 영향력분석을 통해 집중관리지역을 분석할 수 있었다.

Beginning of the human ecology in 1920s, the efforts for applying the environmental values to a policy have been embodied by the enactments of international agreement and relevant laws. The government has been struggling to adopt the environmental values for the policy by enacting the relevant laws and establishing the environmental value evaluation information (environmental conservation value assessment map, eco-natural map, biotope map). In spite of the efforts to apply the environmental value assessment information for the habitat potential of wildlife, the application is being challenged by the discrepancy in methods and criteria. Thus this study intends to measure the potential of wildlife habitat and apply it to the spatial value classification for the application plan of wildlife habitat potential in policy. Maxent was used for the habitat potential and the land types were classified depending on the surface and land use pattern of cadastral map. As a result, the policy matrix including conservation strategy(CS), restoration strategy(RS), practical use strategy(PS) and development strategy(DS) has been deduced as CS 13.05km2(2.38%), RS 1.64km2(0.30%), PS 162.42km2(29.57%) and DS 8.56km2(1.56%). CS was emerged mostly on forest valleys and farmlands, and RS was appeared in the road area near the conservation strategy areas. Boryung downtown and Daecheon Beach were the center of DS, while the forest and farmlands were presented as PS. It is significant that this study suggest the new approaching method by comparing the wildlife habitat potential with the land type. Since this study evaluated the environmental value by one species of leopard cat (Prionailurusbengalensis) with Maxent model, it is necessary to apply the habitat potential measuring method for various target species as further research.

본 연구는 2011년에 수행된 충청남도 보령시 도시생태현황지도(biotopemap)에서 도출된 정보를 활용하여 야생동물 조사지점을 선정하는 단계에서 활용하기 위한 목적으로 수행되었다. 연구에 활용된 정보는 야생동물 전문가의 지식과 경험으로부터 도출되었으며 6가지 환경변수(Outside distance from food vegetation, Outside distance from farm land, Outside distance from forest, Human density, Outside distance from road, Outside distance from water)로 구현되었다. 6개의 환경변수는 도면중첩방법으로 모형화 되었으며 모형은 출현정보와 비교한 결과 94.72%의 상관관계를 도출할 수 있었다. 출현이 많을 것으로 예측된 지역은 농촌지역 산림 계곡부였으며 조사범위의 한계(면적, 일정, 예산)속에서 양질의 야생동물 조사결과를 도출하기 위해 활용될 수 있다. 하지만 산림내부가 제외되어있는 점, 모든 종이 같은 서식지를 선호하지 않는 다는 점 등의 한계점을 갖고 있었으며 추후 이 부문에 대한 후속연구들이 필요하다. The aim of this study was to use the information deduced from biotopemap in Boryeong, Chungnam province conducted in 2011 and to select the wildlife survey point. The information used for the study was deduced from the knowledge and experience of wildlife specialists and was realized by 6 environmental variables (Outside distance from food vegetation, Outside distance from farm land, Outside distance from forest, Human density, Outside distance from road, Outside distance from water). 6 environmental variables were modeled by map overlay method and the model could deduce the correlation of 94.72% as a result of comparing with occurrence information. The areas predicted to have many occurrences were rural landscapes, forests, and valleys, and they can be used to deduce the quality wildlife survey results in the limit of survey range (area, schedule, and budget). However, it had the limit points such as the inside of forests was excluded, all species did not prefer the same habitat. The following studies are needed for this part in the future.

The purpose of this study is to detect the protection area around the Gewn-buk and Gewn-nam Mountains for making a sustainable ecological network. The protection area in the Gewn-buk and Gewn-nam Mountains was analyzed by using spatial data and a field survey for landscape conservation purposes. A survey scope was fixed using digital elevation model, and the protection area was finally determined based on the parcel map called as the Korea Land Information System (KLIS). Here we have several conclusions in this study. First, spatial data used in this study were a map of ecological and natural degree (MEND), forest distribution map, elevation map, slope map, and several maps for the protection area assigned by laws regarding to the natural resources. Second, we used 4 alternatives to determine the best choice for showing the ecological network in the study area. One alternative (alt. 3) of 4 ones was finally chosen as the best condition for making the ecological network. The condition in elevation and slope was a little modified to a lower level in alt. 3. The result derived from alt. 3 reflected the continuity and connectivity in the ecological network and we estimate that the protection area can protect the core area using the buffer zone around the ecological network. Finally the parcel-based protection area in the Gewn-buk and Gewn-nam Mountains had 493.92km2 of the core area, and 233.99km2 of the buffer zone, which means the parcel-based protection area increased by 97.76km2 in the core area, but decreased by 76.6lkm2 as of in the topographical map.

Climate change is considered a severe global problem closely related to carbon storage. However, recent urbanization and land-use changes reduce carbon stocks in terrestrial ecosystems. Recently, the role of protected areas has been emphasized as a countermeasure to the climate change, and protected areas allow the area to continue to serve as a carbon sink due to legal restrictions. This study attempted to expand the scope of these protected areas to an evaluation-based environmental spatial information theme map. In this study, the area of each grade was compared, and the distribution of land cover for each grade was analyzed using the Ecological and Nature Map, Environmental Conservation Value Assessment Map and Urban Ecological Map of Sejong Special Self-Governing City. Based on this, the average carbon storage for each grade was derived using the InVEST Carbon model. As a result of the analysis, the high-grade area of the environmental spatial information generally showed a wide area of the natural area represented by the forest area, and accordingly, the carbon storage amount was evaluated to be high. However, there are differences in the purpose of production, evaluation items, and evaluation methods between each environmental spatial information, there are differences in area, land cover, and carbon storage. Through this study, environmental spatial information based on the evaluation map can be used for land use management in the carbon aspect, and it is expected that a management plan for each grade suitable for the characteristics of each environmental spatial information is required.

기후변화에 대응하기 위한 정책 수립과 이행을 위해 온실가스 인벤토리 작성의 중요성이 대두되고 있다. 이에 따라, 토지이용 항목과 변화들에 대해 공간 명시적으로 나타낸 Approach 3 수준의 Land Use, Land-Use Change and Forestry(LULUCF) 매트릭스 구축 필요성이 제기되고 있다. 본 연구에서는 LULUCF 매트릭스의 산림 항목을 중심으로 연속지적도, 중분류 토지피복지도, 임상도, 도시생태현황지도를 활용하여 LULUCF 매트릭스 구축에 적합한 공간정보를 검토하였다. 각 공간정보에 대한 분류 속성 비교를 실시하였고 충청남도 보령시를 대상으로 양적(면적) 비교, 질적(특성) 비교를 실시하였다. 양적 비교 결과 산림의 면적이 임상도에서 최고 50.42%(303.79㎢), 지적도에서 최저 46.09%(276.65㎢)의 차이를 보였다. 질적 비교 결과 자료 구축 범위 차이, 자료 구축 목적 차이, 분류 항목 차이, 일필일목의 원칙 적용 여부의 차이, 자료구축 시기 차이 등 5가지 질적 특성의 차이를 확인하였다. 연구 결과 도시생태현황지도가 LULUCF 매트릭스 구축에 가장 적합한 공간 정보로 판단되었으나 전국구축이 되어있지 않은 한계로 토지피복지도가 가장 적합한 것으로 검토되었다. 또한, 도시생태현황지도, 임상도, 토지피복지도 등을 서로 종합하여 LULUCF 매트릭스를 구축하게 될 경우 각 공간정보의 한계를 보완할 수 있을 것으로 사료된다. 추후 전국토를 대상으로 하는 1:5,000 수준의 세분류 토지피복지도 및 도시생태현황지도가 완료 될 경우 LULUCF 매트릭스 작성의 정밀도를 향상시킬 수 있을 것으로 판단된다. The importance of establishing a greenhouse gas inventory is emerging for policymaking and its implementation to cope with climate change. Thus, it is needed to establish Approach 3 level Land Use, Land-Use Change and Forestry (LULUCF) matrix that is spatially explicit regarding land use classifications and changes. In this study, four types of spatial information suitable for establishing the LULUCF matrix were analyzed - Cadastral Map, Land Cover Map, Forest Map, and Biotope Map. This research analyzed the classification properties of each type of spatial information and compared the quantitative and qualitative characteristics of the maps in Boryeong city. Drawn from the conclusions of the quantitative comparison, the forest area showed the maximum difference of 50.42% (303.79㎢) in the forest map and 46.09%(276.65㎢) in the cadastral map. The qualitative comparison drew five qualitative characteristics: data construction scope difference, data construction purpose difference, classification standard difference, and classification item difference. As a result of the study, it was evident that the biotope map was the most appropriate spatial information for the establishment of the LULUCF matrix. In addition, if the LULUCF matrix is made by integrating the biotope, the forest map, and the land cover map, the limitations of each spatial information would be improved. The accuracy of the LULUCF matrix is expected to be improved when the map of the level-3 land cover map and the biotope map of 1:5,000 covering the whole country are completed.

The purposes of this study are to apply species distribution modeling in urban management planning for habitat conservation in non-urban area and to provide a detailed classification method for management zone. To achieve these objectives, Species Distribution Model was used to generate species richness and then to compare with the results from land suitability assessment. 59 species distribution models were developed by Maxent. This study used 15 model variables (5 topographical variables, 4 vegetation variables, and 6 distance variables) for Maxent models. Then species richness was created by sum of predicted species distributions. Land suitability assessment was conducted with criteria from type Ⅰ of “Guidelines for land suitability assessment”. After acquiring evaluation values from species richness and land suitability assessment, the results from these two models were compared according to the five grades of classification. The areas with the identical grade in Species richness and land suitability assessment are categorized and then compared each other. The comparison results are Grade1 10.92%, Grade2 37.10%, Grade3 34.56%, Grade4 20.89% and Grade5 1.73%. Grade1 and Grade5 showed the lowest agreement rate. Namely, development or conservation grade showed high disagreement between two assessment system. Therefore, the areas located between urban, agriculture, forest, and reserve have a tendency to change easily by development plans. Even though management areas are not the core area of reserve, it is important to provide a venue for species habitat and eco-corridor to protect and improve biodiversity in terms of landscape ecology. Consequently, adoption of species richness in three levels of management area classification such as conservation, production, planning should be considered in urban management plan.
