  • The purpose of this study is to provide a basic datd for establishing a basic park management plan for Bulamsan Urban Nature Park. This research surveys very closely about the present condition of the natural ecosystem based on the examination and analysis of the present condition. This research suggests development and management methods for environment-friendly park by understanding damages on the ecosystem due to overuse, as well as park facilities and their effects on the surrounding environment, using quantative analysis. The three steps: researching the present condition research, ecosystem evaluation, and park management plan were taken in order. The present condition research is based on the general condition, natural environment, and natural ecosystem data. In the ecosystem evaluation, wildlife habitats evaluation, landscape evaluation, and biotope type research which is a materialized form of the plant ecosystem were excuted based on the present condition research data. In the park management plan step, 1) classified ecosystem and landscae preservation zone, ecosystem protection zone and ecosystem restoration zone as ecosystem and landscape preservation plan, 2) plannings for ecosystem, fine landscape preservation, damaged area restoration and recovery plan were established in order to suggest environment-friendly plan,

  • Biodiversity refers to the diversity of organisms originating from all sources, including terrestrial ecosystems, aquatic ecosystems, and complex ecosystems and it is considered to be the standard of the area to be preserved and protected. So The Importance of environmental assessment for biodiversity conservation is increasing and International efforts to quantify biodiversity and to develop indices have been made, but there are insufficient researches on the use of biomass databases and their quantification in Korea. In this study, the biodiversity map was constructed using the 3rd National Ecosystem Survey Mammal Data with three spatial units(Administrative Area, 1:5,000 index map, hexagonal lattice). and the difference of map constructed by spatial unit was suggested to help research on quantification and evaluation of biodiversity in the future. As a result of the study, biodiversity index for the same area varied according to the spatial unit and overall average and standard deviation were different too. Therefore it is necessary to utilize appropriate spatial unit considering the suitability and purpose of quantification rather than using specific unit. It also showed the necessity of establishing a standard for biodiversity index as a result of comparative analysis with ecosystem and nature map. Based on this research, comprehensive efforts should be made for the sustainable development of the country through further research and institutional improvement for quantification and evaluation of biodiversity, set standards.

  • A method of conserving the vegetation at Mt. Chonggye was established to persue a practical management of the natural ecosystem by the vegetative composition analysis. As a result, the vegetation of surveyed areas was classified into two communities and four subcommunities in Mt. Chonggye. Potentilla fragarioides var. major community, known as the roadside plant community, distributed near trails under heavy human impacts. Potentilla fragarioides var. major community included two subcommunities : Digitaria sanguinalis-Ambrosia artemisiifolia var. elatior subcommunity and Rhus chinensis subcommunities. In these communiyies, there were many naturalized plant species such as Aster pilosus and Artemisia princeps var. orientalis, known as heliophilous plant. Results indicated that the vegetation had been affected by intensive human activities. It is necessary to control the naturalized plant species such as Aster pilosus for conservation of the ecosystem and nature in this area. Quercus mongolica community, a common coppice woodland in central Korea, was mostly distributed around mountain tops and ridges above 529 m altitute. In the valley where the forests well conserved, the Quercus mongolica community contained the Syneilesis aconitifolia-Hemerocallis lilioasphodelus subcommunity. On the other hand, Potentilla dickinsii subcommunity was dominated in dry rocky ridge areas. In these areas, however, the vegetation and forest soil was not properly managed for conservation.

  • Due to international law the Antarctic is currently the best protected large ecosystem on earth, providing the opportunity for scientific research into processes of both regional and global importance. However, it is impossible to carry out research activities without minor disturbances to the environment. The Weddell Sea with its shelf inhabiting fauna can be considered to be representative for the entire Antarctic shelf with exceptions. It has generally escaped major anthropogenic impact but it is the only area in the high latitude Antarctic where long-term research fishing has been carried out. There are two main results combining aspects of nature conservation and benthos research. Firstly, the use of dredges has clearly decreased over the last two decades, whilst the use of non-invasive underwater photography and video has significantly increased. Secondly, during the same period icebergs destroyed an area of the seafloor and its fauna more than 2000-times greater than the area affected by research trawls. The increased use of imaging methods, Remotely Operated Vehicles (ROV) and other modem instruments, as well as statistically based and coordinated sampling strategies can contribute to both a better understanding of ecosystem function and to an ongoing reduction in anthropogenic impact.

  • The purpose of this study was a biota research and analysis for Close-to-nature stream restoration planning of Shinchun. The summary of this study is as follows; 1) The vascular plants in research area recorded of 45 species and insect fauna recorded of 34 species of 8 orders. As a result of table of community classification, the communities were two group; Quercus variabilis community(I), Pinus densiflora-Quercus variabilis-Quercus dentata community(II). 2) As a result of analysis on correlation of tree species, the level of significance in positive correlation between Quercus dentata and Corylus heterophyll aindicated 1% and between Pinus densiflora and Lespedeza bicolor also indicated 1%. 3) As a result of DBH analysis, it is expected that Quercus variabilis and Quercus dentata will dominateover other species in competition and its succession continuously maintains from now on in community I. In community II, it is assumed that there is a high possibility of changing into community of Quercus such as Quercus mongolica, Quercus dentata, and Quercus variabilis. 4) As a result of analysis on insect fauna, insect fauna consists of 94% of whole species as 32 species, 23 families, 8 orders. And 7 species, 7 families 4 orders was found in highly urbanized area, the vicinity of Sang-Dong bridge. 5) As mentioned above, Based on A biota fundamental research, Close-to-nature stream restoration planning were full of suggestions: i) Designating ecosystem preservation area, ii) Making Close-to-nature stream revetments, iii) Making pool-and-riffle, vi) Making decks for observation and walks for nature experience, v) Creating wetland biotope. Through these methods, it is necessary to promote bio-diversity and lead people to the space for eco-learning.

  • 1. It is man that plays a important role in doing harm to ecology. So human ought to understand ecology and develop their mind considering a ecology through practicing Noble eightfold Path(入正道) austerities. 2. With a view of traditional Korean medicine, it is accomplished the circulation between human and heaven and earth by Qi. And then these are inter-transformed essence, Qi and spirit and carry out unification themselves by coexisting with university. 3. I consider 'Well-being' is man-centered thinking countering to the view of ecology. Then the health of body and spirit is accomplished through the life harmonizing with nature incidentally. 4. It is need for realizing that man and nature have the mercy of Buddha in order to purify a ecosystem and our human society through practicing austerities and meditation. 5. Spirit is regarded as the important thing on Buddhism and traditional Korean medicine based on Orientalism. The purification of human mind is very important for maintaining of a ecosystem through practicing austerities and meditation.

  • The southwestern islands of Japan, especially southward from Amamioshima Island, have distinguished sets of nature and culture. However, various problems are arising on those islands. This report first introduces island characteristics as well as, their status briefly. Then it introduces conservation efforts. Since nature and culture are closely connected in the island system, conservation of the set of nature and culture is essentially important. From this point of view, this report focuses on two efforts. The first example is the effort for designation of a new national park with a new concept of "environmental culture type" and "ecosystem management type" in the Amami Gunto Islands. This effort is a new challenge to focus on the importance of cultural aspects. The second example is the unique effort of the national park visitor center to conserve as one set of integrated nature and culture with an alliance of all stakeholders in Taketomijima Island, Iriomote-Ishigaki National Park. The visitor center serves not only visitors, but also islanders. These two cases are good models that suggest hints for future conservation measures.

  • This study is going to contribute the activation of ecosystem services written in the 3rd National Basic Plan for Nature Conservation(2016~2025) in Korea. Meanwhile we considered the benefits that the nature has given to the humankind as free goods or services which we may consume traditionally without due payment therefore. But on account of the expansion of cities and expedition of development, as the carrying capacity of the nature has been breached, people have come to try to restore and enhance artificially such vulnerable capacity. It is necessary to compensate the opportunity cost which the land owners or occupiers have to pay for conservation and maintenance of natural capitals which yield the ecosystem services. Therefore the institutionalization of ecosystem services should be established that the consumers who enjoy such services should share the interest from enjoying services with the land owners or occupiers who produce the ecosystem services, under the legal system which will make it possible to connect the benefit sharing with the conservation of environment. However it is the first task that the present legal system could not realize the fair and equitable benefit sharing between the producers and consumers of ecosystem services. And the second task in such legal system is that the value of ecosystem services could not be fully considered in the process of development planning. According to the analysis of this study, the institutionalization of ecosystem services in the government side and the civilian side could be realized to somewhat extent, although not sufficient. Especially the transactions of ecosystem services through the private contract among stakeholder are possible in the course of development planning or without any relevancy to a development project. The final task in the institutionalization of ecosystem services is how to assess the ecosystem services and to value the economic benefits therefrom on the basis of what kinds of procedures relating to some development processes. To overcome such difficulties, it is necessary that the state, trend and change of ecosystem services confronting with a developing project should be assessed concretely at the threshold of development. It is possible to integrate the ecosystem services into the environmental impact assessment(IEA), not by way of the Act of IEA, but by way of the Decree thereof.

Emergy Valuation of a Tidal Flat Ecosystem in the Southwestern Coast of Korea and Its Comparison with Valuations Using Economic Methodologies (영산강 4단계 간척사업 대상 갯벌생태계 가치의 에머지 평가 및 경제학적 평가와의 비교)

  • The emergy concept was used to valuate the contributions of a tidal flat ecosystem included in the fourth stage reclamation plan for the Youngsan River area to the Korean economy. Emergy contributions of the ecosystem were compared with those of economic valuations performed on the same ecosystem. The tidal flat ecosystem contributed 3.55 million EmW/ha annually. This, however, cannot be compared directly with those of the economic valuations because both methodologies approach the valuation of ecosystems in different perspectives. The emergy methodology is a donor-based valuation in which what goes into making a product or service is measured, while the economic valuation is a receiver-based approach in which human receivers determine the value of an ecosystem product or service. An emergy valuation was conducted for the three ecosystem functions included in the economic valuations to compare the results of both methodologies on the same basis. Fishery production and pollutants removal contributed 9.86 million EmW/ha/yr and 0.88 million EmW/ha/yr, respective1y. The conservation value of the tidal flat ecosystem was 3.55 million EmW/ha/yr. Overall, the emergy valuation that try to include works of both human and nature on the same basis resulted in higher economic contribution of the tidal flat ecosystem than that calculated by the economic methodologies in which only human works are measured based on the willingness-to-pay of people. This study showed that the emergy concept could provide an alternative tool for policy decision-making regarding utilization and conservation of ecosystems by approaching the ecosystem valuation from a different perspective than that of economic methodologies.
