  • Soil seed banks at ecological preservation areas in Seoul, Jinkwannae-dong, Bangi-dong and Bam-sum, were studied by seedling emergence method from May to October 2004. Total number of species and individuals in seed banks were 42 and 5,190 at Jinkwannae-dong, 39 and 2,290 at Bangi-dong, and 39 and 1,047 at Bamsum. Salix koreensis community at Jinkwannae-dong has the highest number of seedlings among all sites. The most abundant species were Lindernia procumbens in Jinkwannae-dong and Bam-sum and Typha spp. in Bangi-dong. The dominant species of seed banks were different from that of plant communities such as Phragmites communis community, Salix koreensis community, Persicaria thunbergii community, Phragmites japonica community, and Populus tomentiglandulosa community. However the dominant species of seed banks in Typha community was Typha spp. Total 63 species emerged in either the wet or submerged conditions. Fifty six species appeared in the wet condition and 25 in the submerged condition. Eighteen species appeared in both conditions. Numbers of species and individuals were much less in the submerged condition than in the wet condition but free-floating hydrophytes including Rorippa islandica and floating-leaved hydrophytes including Monochoria vaginalis appeared only in the submerged condition. In the investigation of soil seed bank by distance from water edge (Bamsum), water side 3 ($300\sim350m$ from water) edge, where water level is fluctuating frequently, has the highest number of seedlings.

  • Seoul is an ancient city with a long history but there is hesitancy over referring to as a historic city due to the lack of traceable historic urban landscape elements which resulted from numerous invasions and general destruction. From a diachronic perspective, the nature which was survived the influence of development, could be the key element that links the past with the city's radically changed image in modern times. Although "old big trees" may be not a dominant influence with regards to the historical authenticity of the city, they are objects which contribute towards the historical authenticity by providing a sense of place in terms of connected narratives, as well as their natural image. However, the protection policy for an "old big tree" would place too much emphasis on the aspect of the ecological value rather than its cultural value. Generally, trees have been protected by installing a fence and a signboard around them as well as receiving additional care. However, it is difficult to find that surrounding space around the "law-protected tree" is connected with its original historical and cultural values. Even though the space around trees are no longer utilized in the same way as was so in the past, they still have high-potential in terms of cultural utilization. Therefore, the subject of this study is the "old big tree" as a natural object which contributed to the historical authenticity of Seoul. The current status of these "old big trees", aged between 100 and 800 years old, currently indicate that there are 215 trees designated as "law-protected tree" by the Seoul metropolitan government. This study aims to investigate the status of protection and utilization of the existing "law-protected trees" in the city of Seoul and find a way to increase both ecological preservation and cultural utilization for the high-potential "law-protected trees" within the city itself. In order to achieve this, previously researched papers shall be reviewed and surveyed pertaining to present usage patterns of the 215 "law-protected trees". In addition, five cases have been reviewed which focus on a few of utilizing the "protected trees" and their surrounding spaces. The results of the research indicate that 21 "old big trees" have high-potential in terms of cultural utilization as well as ecological value. However, it was revealed that there are limitations to pursue the value of preservation and utilization simultaneously throughout current regimental management. In order to cope with the current situation, it is pointed out that management facilities should be designed and installed by creative and flexible methods of organizing with consideration to the surrounding space and context. Even though in the case where there may not be a connecting history or legendary stories, the "old big trees" can serve as the fundamental features of small scale parks -dependent on their location, condition and environment- which will be of value to the local communities. This study could serve as a practical reference for the management and utilization of "old big trees" nationwide with numbers reaching 12,300 besides the city of Seoul.

  • The purpose of this study was to find ecologically stable areas involving the locations in which wildlife exist, and to earmark those places as "ecologically connected areas requiring preferential preservation," and through that, to reduce the perils that may occur due to urban development or road construction. The processes and the results of this study were as follows: 1. Selecting the spots in which wildlife may exist: The total study areas were analyzed by eight ecological indexes and then a total of 500 locations in study areas were selected. 2. Sorting the locations in which mammals exist: We surveyed each one of the 500 locations twice, and then confirmed that we found mammals at 492 of the 500 locations and analyzed 264 locations that the number of existing mammals was above average. 3. Analyzing the 264 locations with two indexes, the number and the frequency of the land use types: 5~7 types of land use were suitable. The types were forest, rice field, farm, river, and meadow, excluding building and road. 4. Selecting the locations that meet the above conditions: We sorted 89 locations and earmarked these points as "ecologically connected areas requiring preferential preservation" in order to expect continued existence of wildlife.

  • Background and objective: This study was carried out to assess the relationship between the internal and external environments and the ecological items in five sites with a high level of artificial use intensity prior to the establishment of Geumgang River riparian ecological belts. Methods: The sites were classified into forest type, cultivated land type and urbanized type in accordance with their respective locational types. Ecological items including plant ecology such as proportion, naturalization index and urbanization index of native species were analyzed and animal ecology such as the number of species and population of wild birds, amphibians and reptiles, mammals, and butterflies and dragonflies, which are indicator insects, were investigated. In addition, species diversity indices of wild birds, butterflies and dragonflies found in all the subject lands were computed. Results: Among the plant ecological items, the ratio of native species in the forest type was higher than 90%, which was a satisfactory level, while the naturalization and urbanization indices were less than 10%. The number of species in the animal ecological characteristics was reduced in the order of forest type, cultivated land type and urbanized type. As the results of correlation analysis, the internal area of the planted area showed a negative correlation with the total of individuals. The area of grasslands showed a positive correlation with the number of dragonfly species and the total number of individuals, thereby illustrating that wet grasslands have positive effects. The area of surrounding forests, as an external environment, had a negative correlation with the urbanization index (UI) but a positive correlation with the inhabitation of butterflies and the total number of species. Conclusion: The results confirmed the need for more diversified special compositions including planted land, grassland, wetland, bodies of water and waterways within the subject land in the wetland ecological belt along with the need for surrounding forest location and preservation from the perspective of purchase and restoration of land for enhancement of wider biodiversity in the future.

  • This research has a meaning to provide basic data for eco-friendly way of district unit plans and ecological landscape planning by evaluation of biotope preservation value at the level of district unit and designating land development of the site, the whole area of Sinseo-dong (Dong-gu, Daegu metropolitan city) for research site. The summary of analysis result is as follows. As a result of classification of biotope types on the research site, it is divided into 11 biotope groups such as a residential biotope group and 51 specific biotope types which is subordinate to the groups. As a result of the first value assessment on classified biotope types, there are 16 types of natural rivers which is full of vegetation as a I class. Also it is analysed as 9 types of IIclass, 14 of IIIclass, 8 of IVclass, and 4 of Vclass. In particular, in light of a wildlife habitat, EB, in case of broad-leaved tree of mixed forest assessed as a II class, was classified into Iclass which is one-step upgraded as a final class with the analysis as there is a structural characteristic (more than 71% of low density, 50 years of age-class). As a result of second assessment, it is analysed that there are 17 special sites (1a,1b) and 33 special sites (2a, 2b, 2c) respectively for preservation of species and biotope. Particularly, in case of the No. 27 space, it was assessed that it has the value of about medium (IIIclass) level, but its value was upgraded with the on-spot detailed investigation that most of Aristolochia contorta, designated as a rare plant by Ministry of Environment, is growing. It is regarded that the above-mentioned research result on evaluation of biotope preservation value is expected to provide very important basic materials for future district unit plans and smooth integration with landscape ecology plans and eco-friendly space development.

  • The resident attitude for preservation and development of amenity in Eulsuk island and its downstream area at estuary of Nakdong river in Korea were investigated by the questionnaires and the field surveys. Based on the results, the characteristics of this study area are the natural ecological preservation area, natural environmental preservation area and curtural assets for migratory birds. And there are a estuary bank, a Dadae beach and a Molundae park. Special amenities are (1) the light (sunrise, sunset etc), (2) the water(river, sea etc.), (3) the air(fresh wind, beautiful sound etc.), (4) the land space(beautiful view, recreation field, reed area, pine forest etc.) and (5) the stream(dancing of migratory birds, water flow, folk dance, history remains etc.). But at present, the environmental qualities as health, aesthetics safety, amenity and culture are deteriorated by development. So the number of migratory birds are decreasing. The residents desired that in future this area be use for the recreation space, the park and the natural leaning fields etc, as well as the restoration of destroyed resources.

  • The prime objective of this study is to analyze tourist's behaviors and satisfaction of the Gwangneung area and get a reading on the tourist's socio-economic traits and the propensity of activities. In addition, it highlights surveys of the tourist's consciousness of cultural, ecological and environmental tourism resources available in the Gwangneung area and the possibility for sustainable development and ways to make the most of these resources. This study found that even though Gwangneung is mostly a place for one day family outings. the tourist's demand for actually unreachable ecological resources is high while existing cultural tourism resources have less than the expected drawing power. It was also found that tourists recognize the need for preservation of the tourism resources of Gwangneung and its potential for further sustainable development. In particular, most tourists to Gwangneung are relatively satisfied with the status of preservation of its cultural and ecological resources and environment On the other hand, accessibility, tourism facilities, and management are estimated at less than desired. Gwangneung would benefit by making efforts for the positive use of its tourism resources and improvement of convenience facilities, management and operation.

  • As recent interest in ecological resources increases, an effort in three-dimensional visualization of the ecological resources has increased for the restoration and preservation of the natural environment as well as the evaluation of the landscape. However, in the case of forest resources, information extraction has been active, but the effort in trying to apply that information into an effective visualization has not happened. In other words, the effort for effective visualization is lacking when it comes to the visualization of forest resources, and numerous cases are ether non-realistic or the simulation required for analysis is inappropriate. Therefore, this paper extracts information through the use of airborne LiDAR data, aerial photograph, and forest type maps to create a vegetation layer, and then uses Flora3D forest modeling tools and ArcGlobe to accurately visualize the vegetation layer into the three dimension. An effective application for restoration and preservation of ecological resources as well as analysis on the urban landscape can be considered as a result of intuitively and realistically enabling the user's awareness of forest information within the Geographic Information System.

  • This study attempted an eco-ethical approach to the sporting body, focusing on Toegye's Gyeong. A causes for the conflict between man and nature is a wrong view of nature derived from human desire. Toegye thought that the problem of desire could be overcome through Gyeong. Eco-ethical approaches of Toegye's gyeong thought are possible for the following reasons: First, because Toegye's gyeong is completed in nature. Second, because Toegye's gyeong emphasize human responsibility (consideration) for nature. Third, because gyeong is related to the ability to practice morality. Meanwhile, Toegye understood 'preserving the body well' as self-preservation and at the same time, as the meaning of a natural principle of following the laws of nature. From this perspective, the sporting body has meanings of physical fitness and mental health and at the same time, an aspect of ecological values of understanding man and nature as a single network and following the order of nature. Acquisition of Gyeong through the sporting body suggests the practice of 'gyeongsin (respect for the body)' and 'hwalgyeong (preservation of the ecological environment).' When human beings do physical exercise with nature, they proceed to the stage of building up the virtue of yosan yosu (finding happiness in mountains and water) through nature preserving the ecological environment (hwalgyeong) beyond staying at the stage of gyeongsin.
