The city of Siheung in the Kyunggi-do Province has various natural resources such as the ocean, mountains, wide farmland, various types of wetlands, streams and rivers. In addition, the city has a big greenbelt, which consists of two-thirds of the area, where development has been regulated. Since the city has a relatively well-preserved natural environment, it offers a great potential for regional development. The purpose of this study is to create an eco-tourism resource plan for the Mulwang reservoir, which offers many opportunities for ecotourism in the city of Siheung. This study includes a literature review for planning elements and suggests a comprehensive plan that includes conservation, eco-restoration, route program and practice program for ecotourism in and around the site. The plan also includes eco-farming, a visitor center, an ecovillage, the chance to experience livestock farming, opportunities to learn about and experience the forest, tracking, eco-learning, an environmental interpretation facility, fishing and aquatic-oriented leisure activities. This study's process and results show possibilities that can be applied to other areas where eco-tourism using natural resources is used for regional development.

This study was performed for developing the National Environmental Assessment Map (NEAM) in Korea and presenting the application method of NEAM. This NEAM adopted the least indicator method and uses a Geographic Information System (GIS). This map is made through evaluation of 67 items, including greenbelt status and biodiversity. As a result, the construction of NEAM was defined as a process of identifying land use to scientifically assess the physical and environmental value of land and classify conservation value into several grades for the sustainable management of environmental resources. After applying NEAM criteria of five degrees to the whole of Korea, Grade I, showing the highest conservation value, accounted for 45.6% by land area of NEAM. Grades II, III, IV, and Ⅴlikewise accounted for, respectively, 23.6%, 17.9%, 6.3%, and the lowest conservation value of 6.6%. This map can be widely used in, for example, urban and regional planning, development planning, and environment impact assessment.

Natural or human disturbances cause landscape changes, which may be measured by the degree of heterogeneity. In a 16km$\times$19km area, divided into 100m$\times$100m cells, of Seoul city and its suburb, land covers are classified into 6 groups in aerial photos and land use maps. The degree of heterogeneity is defined as the number of cells that surround a central cell but have different land cover from the central cell divided by 8. The value of the degree of heterogeneity is between 0 and 1. Major findings are 1) Both urban and natural areas have low degree of heterogeneity, about 0.15~0.17. 2) Suburban area under heavy pressure of development and urbanization has highest degree of heterogeneity, about 0.25. 3) The peak of the degree of heterogeneity moved about 4.5km outward in 22 years. 4) Outer suburban area has lower degree of heterogeneity as the area is a greenbelt or forest. 5) The results show the areas with higher degree of heterogeneity which may need landscape management plans, and natural areas with lower degree of heterogeneity which may need landscape conservation plans. A landscape change model may be built for a specific city when this technique is applied to multiple sectors of the city, and the model may predict future landscape changes of the city.

Desertification has been expanding with a remarkable speed across the Northeast Asia. Desertification in Northeast Asia significantly influences Korea's economy and environmental health conditions in recent years. For these reasons, a number of non-governmental organizations (NGOs) in Korea have carried out the reforestation projects to combat desertification in China and Mongolia. Several tree plantation projects were implemented in Mongolia and China. The objective of this study was to analyze and evaluate the performance of tree plantation aid projects carried out by Korean NGOs in Mongolia. The performance of tree plantation projects was examined through effectiveness, efficiency, equity and responsiveness of those projects. The performance was analyzed with the survival rate of planted trees and planting cost, the recognitions of Mongolian people. The analysis of the performance showed that the tree plantation cooperation projects carried out by Korean NGOs in Mongolia had comparatively high performance from a larger point of view. Especially, effectiveness and responsiveness of their projects were highly marked in spite of all the difficulties of carrying out the tree plantation. Such a high effectiveness represented the relatively higher survival rates of trees and Mongolian's positive recognition of plantation projects. Furthermore, the responsiveness also turned out to be high with a great satisfaction of the Mongolian people for plantation projects conducted by the Korean NGOs. Survey results indicated that the efficiency and equity of the projects would be increased by promoting the cooperation projects for tree planting throughout Mongolia with reinforcing infrastructures. By comparison between Korean NGOs and Mongolian Government plantation projects, confirmed the importance of sustained financial support and maintenance activities in the plantation sites.

우리나라는 도시의 무분별한 확산방지와 도시주변의 자연환경 보전 및 도시민의 건전한 생활환경 확보를 위해 1971년 개발제한구역을 지정하여 엄격한 개발행위 제한조치를 취해 왔다. 그러나 개발제한구역 내 토지소유자의 재산권 요구 증대와 체계적인 관리대책 미흡 등으로 1990년대 후반 개발제한구역제도는 획기적인 전환을 겪었다. 개발제한구역의 지정해제 및 구역조정작업을 거치면서, 개발제한구역제도는 구역경계의 불변성 원칙이 붕괴되었다. 그러나 개발제한구역은 향후 도시주변의 자연환경 보전을 위한 도시녹지지대(greenbelt) 및 도시민에게 개방적이고 친환경적인 오픈 스페이스(open space)로써 활용될 수 있도록 적극적인 보전과 관리대책 마련이 필요하다. 이 글에서는 개발제한구역의 친환경적인 보전 및 관리의 기본방향과 추진전략을 제시하고, 유용한 정책대안으로서 내셔널트러스트 방식의 도입가능성과 제도개선 방안을 살펴보았다. 특히 개발제한구역의 친환경적인 보전 및 관리를 위한 내셔널트러스트의 도입방안 검토에서는 내셔널트러스트의 원리 및 구성요소와 개발제한구역의 친환경적 관리 패러다임과의 연관성, 개발제한구역 트러스트의 설립유형 및 운영방식, 개발제한 구역 트러스트의 대상지 선정기준, 그리고 법제 정비방향을 제시하였다.

Japan has been tried to integrate Western planning theories into its parks and green systems in the past. However this effect has been regarded unsuccessful. One of reasons for this is that the green systems have been treated as an urban facility, instead as systems. Another reason has to deal with greenbelt's stationary and reservation characteristics that make difficulty to respond timely to the rapid urbanization. The parks and green systems in Korea was introduced in 1990 and began to be promoted fully with the 'Parte and Green Master Plan' established in 2005. However, due to its short history, incomplete aspects exist in its philosophy and methods for promoting the system. Based on these experiences, the current green zone plans in Japan considers the green structure as an independent institution and amenity plan, not a tool of urban planning, that can be a medium for realization of urban visions. And main characteristics of this approach are 1) classifying the green structure into four categories in order to respond to urban forms and purposes, 2) pursuing confirmity with urban planning, and 3) executing the landscape plan based upon core green areas. From reviews upon experiences of Japan as well as considerations on demands and conditions of green systems in Korea, we proposed the following five new strategies for the construction of the urban parte and green system in Korea. They are 1) to develop urban parks and green systems into a genre of urban development improving the quality and local competitiveness of cities rather than a means of urban planning; 2) to form the integrated structure of urban green zones; 3) to transform the urban parte and green systems into practical systems as the centers of localities; 4) to raise criteria for planning and execution plans for effective implementations of the urban parte and green systems, and 5) to provide specific guidelines for the construction of urban parks and green systems through organizing research groups or specialists.

The purpose of this study is to suggest the landscape potential index for visualizing landscape information in the conservation of hilly landscape in urban fringe. For the visual and quantitative approach to topological landscape assessment, numerical entity data of DEM(digital elevation model) were processed with CAD-based utilities that we developed and were mainly focused on analysis of visibility and visual sensitivity. Some results, with reference in assessing greenbelt area of Eodeung Mt. in Gwangju, proved to be considerable in the landscape assessment of suburban hilly landscapes. 1) Since the viewpoints and viewpoint fields were critical to landscape structure, randomized 194 points(spatially 500m interval) were applied to assessing the generalized visual sensitivity, we called. Because there were similar patterns of distribution comparing to those by 56 points and 18 Points given appropriately, it could be more efficient by a few viewpoints which located widely. 2) Regressional function was derived to represent the relationships between probabilities of visibility frequency and the topological factors(topological dominance, landform complexity and relational aspect) of target field. 3) Visibility scores of each viewpoint were be calculated by summing the visual sensitivity indices within a scene. The scores to the upper part including ridge line have been more representative to overall distributions of visual sensitivities. Also, with sum of deviations of sensitivity indices from each single point's specific index to the weighting values of view points could be estimated rotationally. 4) The deviational distributions of visual sensitivity classes in the topological unit of target field were proved to represent the visual vulnerability of the landform. 5) Landscape potential indices combined with the visual sensitivity and the DGN(degree of green naturality) were proposed as visualized landscape information distributed by topological unit.

토지이용의 합리화를 위하여 도입된 토지이용규제는 사회경제적인 발전과 함께 복잡다기화 되면서 국민경제생활에 불편을 초래한다는 이유로 최근 규제 완화로 패러다임이 변화하고 있다. 이에 본 연구에서는 CA 모델을 이용하여 시뮬레이션 함으로써 부산권 도시성장의 잠재지역을 도출하고, 토지이용 규제지역과 함께 공간적 특성을 분석하였다. 분석을 통해 토지이용규제 제도가 실제로 도시성장을 억제하고 토지이용의 효율화를 도모하고 있는지, 또는 국민생활에 불편을 초래할 수 있는 다른 요인이 있는지를 검토하였다. 분석결과 도시외부의 개발압력이 높은 지역에 존재하는 개발제한구역은 토지이용규제라는 역할을 수행하고 있었지만, 많은 지역에서 토지이용에 대한 다중규제가 존재하는 것으로 나타났다. 따라서 순기능을 하고 있는 토지이용규제는 최대한 유지하면서, 도시성장 잠재력이 높은 지역에 존재하는 다중규제를 재고하는 등 다양한 접근과 검토가 필요할 것으로 사료된다.

To utilize the leaves of broccoli, the shape of which was similar with that of kale leaves, as a vegetable juice, the extracts from two types of vegetable leaves were subjected to the analyses of proximate com ponents, volatile sulfur compounds, vitamin C and minerals. The sensory evaluation of the juices, prepared from kale and broccoli leaves, were performed by duo trio test and scoring test. Among eight varieties of broccoli, four varieties('Pilgrim', 'Greenbelt', 'Salinas' and 'Shasta')were not significantly different from kale(p<0.05), based on the duo trio sensory test. Sulfur and nitrogen compounds present in the dichloromethane extracts of kale and broccoli leaves 'Pilgrim' were identified as 3 butenyl, allyl, butyl and 4 methylsulfinylbutyl isothiocyanate(sulforaphane), 4,5 epithiovalero, 4,5 epithio 3 hydroxyvalero, benzenepropane, 3 hydroxy 4 propene, 4 methylthio butane, 3 hydroxy 3 phenylpropane, 5 methy lsulfinylpentane, 4 methoxyphenyl 3 hydroxypropane nitrile and dimethyl trisulfide by GC/MSD analysis. Proximate components were observed to be relatively similar between kale and broccoli leaves. Vitamin C and sugar content were higher in broccoli leaves(125∼180mg% and 8∼12°Brix) than in kale(101mg% and 7oBrix). In mineral analysis by AA and ICP Mass, 'Pilgrim' showed a higher content of K, Fe, Mn, Zn and Se. In separate experiment, sensory scores of bitter taste and astringent taste were lower and scores of over all taste and over all acceptability, higher in broccoli('1243') juice than those in kale juice.
