This study aimed to develop strategies to re-establish the Park Nature Conservation Area in Bukhansan National Park, reflecting landscape ecological value by using the zonation program Marxan with Zones. Planning unit was set by watershed, and the basic data were mapped, considering topographical and ecological values. Mapped indicators were analyzed with the application framework of Marxan with Zones by indexing some indicators. The zones divided into Park Nature Conservation Area (Zone A), Park Nature Environment Area I(Zone B) which is reflected on the concept of Potential Park Nature Conservation Area and Park Nature Environment Area II(Zone C). The best solution for each of the scenarios was fixed through the sensitiveness analysis. From these, the final solution was selected considering five criteria including area ratio of conservation area and grouping. Lastly, the final solution was verified in the overlapped analysis with recent zonation. According to the results, the number of watersheds was 77, with an average area of $1,007,481m^2$. In terms of basic mapping and indexation, the slope index and number of landscape resources for topographical property were average 0.22 and 38 places, respectively. Biotope index was average 0.69 and legally protected species was 14 species, reflecting ecological values. As the social and economic indicators, trail index was average 0.04, and the number of tour and management facilities was 43 places. Through the framework of Marxan with Zones, the best solution for scenario 1 which was set by the highest conservation criteria was selected as the final solution, and the area ratio of Park Nature Conservation Area and grouping was excellent. As the result of overlapped analysis, suggested zonation of the Park Nature Conservation was better than the recent zonation in the area raito (28.3%), biotope grade I(15.4%) and the distribution points (10 places) of legally protected species with verification of proper distribution of conservation features according to the zone.

This study was carried out to create a master plan for an urban eco-forest, including concepts of forest restoration, forest management, and nature education. The concept of an urban eco-forest is different from the original eco-forest, which pursues the conservation of native species in their habitats, using the resources of special plants, etc. The study site was a hill (128m) managed as an urban natural park. Citizens have usually used the park for fitness purposes, as a place for outdoor exercise early mornings on weekdays and holidays. The result of a questionnaire survey showed that the users knew about the eco-forest, and they wanted to participate in the nature education programs. The flora and actual vegetation were weak about conservation of native species on the site. The framework of the plan consisted of development of the ecological forest and forest restoration, and allowed for recreation and the experience of nature, according to the concepts of the urban eco-forest. The landscape was divided into the experience zone of biodiversity, the experience zone of a valley ecosystem, the forest restoration zone, and the recreation and experience zone in nature. Based on this framework, detailed programs and theme areas were planned, as were forest restoration models and planting plans.

Chirisan National Park, the first and largest one out of 20 national parks in Korea, is divided into five zones. They are composed of nature preservation zone, natural environment zone, natural residential zone, concentrated residential zone, and collective facility zone. However, the park is not a continuous habitat: roads, trails, local residences, and various facilities created the habitat mosaics severely fragmented. We investigated the fragmentation pattern of the park due to roads and mountain trails using GIS. Based on perimeter length, area, and the ratio of perimeter to area of each patch, we obtained landscape analysis indices which reflect the regularity of the patch shape. The 1 m-wide hiking trails divided the park into 491 fragments. The legal trails with 1.5 m - 3 m width which have been heavily used by hikers generate 58 fragments. Even the nature preservation zone, corresponding to a core zone comprising 31.8% of the park area, was divided into 37 fragments because of the roads and mountain trails. With the different widths of buffer applied, the core sizes of the fragments were reduced. When the 60 m buffer was applied, the patch interior areas ranged from 0.0001 to 47.77 $km^2$ with a mean of 7.08 $km^2$. The landscape shape indices were far greater than 1 for most of the cases with a maximum value of 25. These results clearly indicate that Chirisan National Park is not a continuous habitat, but mosaics of small, irregularly shaped habitat fragments. It is necessary to take the size and shape of the fragmented habitats into consideration when nature conservation is planned, especially for large wildlife such as brown bears.

1. This paper suggests one educational model of National Parks. The model includes main themes such as (1) concepts, (2) waste types, and (3) conservation policies of National Parks for the application at the school environmental education classes. 2. The study describes the origin of the national park system and concepts or policies for the conservation of the parks with cases of Japan, Taiwan, Canada, Australia, Swiss, Russia, and International Union for the Conservation of Nature and Natural Resources(IUCN). The main focuses of their concepts or policies are on the (1) public land, (2) conserved, (3) legally protected land, and (4) land for the education of the loving their country. 3. This research classifies wastes of parks as point, linear, areal, and cubic types, and explains wasting actions on each types, focused mainly on the mountainous national parks. 4. The suggested policies for the conserving national parks, in this paper, are (1) core-zoning policy, and (2) management policy within the core zone. 5. Some principles are suggested for the more effective realization of the policies: (1) enforcement, (2) abandonment,(3) restoration, (4) enlargement, (5) limitation, (6) incorporation, (7) monitoring, and (8) education. 6. Finally, the educational values of this model may be derived from concepts of (1) loving national land, (2) conservation of nature, (3) public responsibility for protection, and (4) education materials. Those concepts form the foundation of models for (1) civic education, (2) education of country, and (3) inquiry training.

도로는 생태계를 교란시키는 인간 활동의 지표이며 흔히 서식지 단편화, 서식지 축소, 서식지 고립을 유발한다. 제주도의 한라산국립공원(면적=153.4$km^2$)은 지형, 지질, 생물상의 특이성이 높으며 유네스코 생물권보전지역(MAB)의 핵심지역으로도 중복 지정되어 있다. 공원의 이러한 높은 보전가치가 많은 탐방객과 도로건설을 유도하고 있음에도 불구하고 도로로 인한 경관의 변화는 거의 알려진 바가 없다. 본 연구에서는 GIS를 활용하여 한라산국립공원의 도로로 인한 서식지 단편화 양상을 공원 용도지구, 해발고도, 식생에 관련하여 분석하였다. 포장도로와 법정 비법정탐방로에 각각 112m, 60m 버퍼를 적용시킨 결과 한라산국립공원은 총 100개의 단편으로 나뉘었다. 포장도로와 법정탐방로만을 고려했을 때 드러난 10단편의 면적은 $0.002km^2-38.2km^2$(평균면적=14.2 $km^2$)에 이르렀고 자연보존지구와 자연환경 지구 모두에서 각기 약 7%가 가장자리로 판정되었다. 이들 단편의 형태지수 평균은 5.19(100단편 중), 7.22(10단편 중)이었지만 공원의 동서 양단과 정상부근에 있는 단편들의 형태지수가 보다 높았다. 5개의 법정탐방로가 모두 분화구까지 연결되어 있고 고도가 높아짐에 따라, 활엽수림, 침엽수림, 초지로 식생이 전환되기 때문에 높은 고도, 특히 고유식물과 고산식물이 많은 고도 1,400m이상의 초지에서 서식지 면적이 현저하게 감소했다. 이런 결과는 한라산국립 공원도 도로로 인한 서식지 단편화를 겪고 있으며, 단편화로 인한 서식지 악화와 서식지 소실의 위험이 공원의 자연환경 지구보다 한라산 정상의 백록담을 중심으로 하는 자연보존지구에서 더 높을 수 있음을 보여준다. 따라서 한라산국립공원의 현 도로망은 생태계 보전과 보호라는 국립공원의 목표에 부합하지 않는다고 사료된다. 한라산국립공원 전체가 또한 MAB 핵심지역임을 고려한다면, 공원 용도지구의 재설정과 단편화를 완화시키기 위한 공원 내 도로관리에 보전노력이 경주되어야 할 것이다.

The Ministry of Environment of Korea has been releasing Asiatic black bears since 2004 at Jirisan National Park. It exceeded the target number of Asiatic black bears in 2018. As of July 2020, in addition to 67 traceable bears, many Asiatic black bears are dispersed outside Jirisan National Park. Jirisan National Park is a very dense place with more than 3 million visitors every year. In this study, the roads and trails through Jirisan National Park were considered to be the main dispersion factors of Asiatic black bears, and the fragmentation analysis was conducted. As of July 2017, the length of roads and trails in Jirisan National Park was 363.4km. Based on this, Jirisan National Park was fragmented into 163 patches. There is only one place that maintains a single area of more than 50㎢ that is suitable for large mammals to inhabit, and 141 places are less than 5㎢. There are 6 patches of 24 to 200㎢ area suitable for living of large mammals including Asiatic black bears, in Jirisan National Park. Compared to the announcement made by the Korea National Park Service in 2014, activities of Asiatic black bears were rare in areas below 5㎢ area and the frequency of activities was high in more than 20㎢ area. This shows that human activities in protected areas such as national parks can directly affect the activities of wild animals, including Asiatic black bears. Therefore, efforts should be made to improve the habitat of Asiatic black bears by reducing the pressure of visiting for Jirisan National Park. In addition, as a result of analyzing the fragmentation of the park's natural conservation zone 107.7km, 45% of the trail of Jirisan National Park, was opened, which is more fragmentation than other use zones. The park nature conservation zone accounts for about 32% of the total area of Jirisan National Park, but the average patch area is only 2.93㎢ and seven large shelters are located. Therefore the Asiatic black bears are negatively affected. This is the result of inconsistent national park use zone setting and actual park management. In overseas countries, research is active on the negative effects of human activity on ecosystems in protected areas. However, there is a lack of research of that in Korea. Thus, that research is required for protection area management in the future.

This study analyzed the relationship between NDVI(Normalized Difference Vegetation Index) and urban heat island in three cities: Daegu, Kyungju, and Pohang for understanding the degree of nature conservation concentrating in the transition zone of them. Daegu city is the third city in Korea which has a dense population. Kyungju is a traditional city which has good nature. Pohang is an industrial city which has those of characters of Daegu and Kyungju. Landsat 1M data in May 17, 1997 were used for the analysis of heat island. There were about four theoretical models to estimate the surface temperature from TM data: Two-point linear model, Linear regression model, Quadratic regression model, and Cubic regression model. In this study, Linear regression model had been utilized to analyze the urban heat island. On the resultant images, the transition zone of Daegu was urbanized more extremely than those of other two cities. It is thought that the analysis of relationship between NDVI and surface temperature, used in this study, is regarded as one of effective methodologies for urban-environmental detection from satellite imageries.

민통선이북지역은 주민들의 열악한 생활환경 개선을 위한 지역개발이냐 자연환경보전이냐의 상반되는 의견으로 끊임없는 논란을 야기시켰다. 이에 본 연구는 민통선이북지역에 거주하고 있는 주민들과 공무원들의 민통선 일원의 자연환경에 대한 인식과 자연환경보전 및 개발에 대한 태도를 알아보기 위해 파주시와 연천군 민통선지역 주민 265명과 시 군공무원 285명을 대상으로 설문조사를 실시하였다. 주민과 공무원들은 민통선 일원의 우수한 자연경관과 자연환경 및 다양한 생물종 보유에 대해 긍정적으로 인식하며 이에 대한 자부심과 긍지가 높은 것으로 나타났고, 자연환경은 많이 훼손되어 잘 보전되지 못한 것으로 인식하고 있으며 특히 연천지역 주민은 더 그렇다고 응답했다. 전체적으로 주민들이 자연환경보전을 우선시하거나 최소한 보전과 조화를 이룬 개발을 원하는 것으로 파악되었고, 지역 공무원들 또한 지역의 발전을 위한 희생적인 태도가 강한 것으로 파악되어 민통선지역에 대한 지속가능발전의 인식 토대는 긍정적인 것으로 평가되었다. 지역별로 처한 상황에 따라 주민과 공무원간의 의견차이가 유의미하게 나타났는데 파주지역의 경우 주민들이 지역개발을 더 원하는 데 비하여 공무원들은 환경훼손에 대한 우려와 자연환경보전 의지가 상대적으로 더 높아 갈등이 예상되었다. 향후 지역개발과 자연환경보전의 목표를 동시에 달성하기 위하여 자연환경에 대한 학술조사와함페 주민의 의사를 충분히 반영하고 조화롭게 진행되도록 지역주민의 생활환경에 대한 심층적이고 지속적인 연구가 요구된다.

Despite its ecological importance of wetlands in our life, wetlands around cities and villages have been steadily disappearing. It is mainly due to either natural geological changes or man-made causes such as permitted land zone changes for the purpose to convert to agriculture land. This study aims to establish a comprehensive database of wetlands using GIS in a historic conservation city Gongju City. The systemic data management would enable to identify distribution of wetlands and their ecological attributes, and to estimate the conservation value of the wetlands. The data base will be able to use in strategic way to preserve the local ecological areas for local residents and tourists and manage the quality of wetlands in the historic and conservation city. For the purpose, it is suggested organising a wider network with not only local residents but local authorities and relevant stakeholders would be beneficial. This study also recommends that long-term strategic plan to preserve the existing wetlands. This study findings as a seminal case example can be used to apply to other geographical areas of the country and can contribute to create a national ecological nature map as well as evaluate the attributes and quality of natural ecosystem service of the region.
