  • In this paper, we reviewed the assessment criteria and conservation value used to evaluate vegetation. The Degree of Green Naturality (DGN) and the Grade of Vegetation Conservation (GVC) are both sets of criteria that estimate the degree of human disturbance or natural value of vegetation. The criteria are extensively used in decision-making about the natural environment conservation and environment impact assessment. Sometimes, social issues can rise because the criteria are not clear. This study aims to evaluate the criteria based on the many aspects of the related literatures and suggest reasonable revised criteria. In addition, criteria for representing the relative value of valuable vegetation conservation are suggested. The DGN and GVC are essentially same; both have 11 degrees and 5 grades. While the DGN is subdivided into levels of anthropogenic disturbances, the GVC indicates the priority for conserving valuable vegetation. Therefore, the DGN is very useful for assessing land development projects, etc., while the GVC is needed to delineate the Ecological Assessment Map(EAM). In conclusion, it is desirable that both criteria should be used together appropriately.

  • The environmental conservation-targeted zoning in urban planning process has been functioned as securing a ecological core in urban green spaces management. Hence, the designation of conservation zones in land use planning is considered as a key task to achieve the sustainability of urban planning. The recently introduced pre-environmental review system for the proposed urban plan, by which the conservative measures for urban ecosystem and landscape are suggested in aspect of environmental impact mitigation, has played an active role in enhancing the environmental performance degraded by wide range of development pressure. This study is aimed at drawing out of objective criteria for designation of environmental conservation zones, which can be applied to urban planning establishment and also to environmental assessment process. To achieve this goal, the study adopted the following methods; pre-study review, analysis of existing official opinion statements released by the Ministry of Environment, contents analysis of related laws, and experts' panel discussions on the finally arranged criteria. The results of this research can be summarized as follows: First, the total criteria of 48 are drown out with categorizing into environment-ecological and socio-cultural sectosr. Second, the environment-ecological part is composed of 33 criteria such as vegetation, animal, geomorphology, watershed, environmental land suitability, and etc. Here, the Degree of Ecological Function, Degree of Environmental Land Suitability, and Vegetation Map are mainly utilized. Third, the 15 socio-cultural criteria relating to the history, social ecology and landscape have such components as forest around relics, Seo-won(school), castle, tomb, landmark, skyline, natural landscape, and etc. Forth, these individual criteria can be applied to designation of each conservation zones among total of 11 conservation areas(or districts).

  • Taxidermied specimen is the art of preparing, stuffing, and mounting the skins of animals (all vertebrate species of animals including mammals, birds, reptiles, and fishes) for display or for other sources of study. But, as these studies are weighted toward ecologic study, related studies on management and conservation environment are short. Also, the analysis of poisonous gas has not yet been studied. Therefore, this study will be suggested proper preservation methods through the analysis of deterioration on taxidermied specimen by poisonous gas. As a result, 4 types of major chemicals were detected in UV deterioration test, 7 types in RH and formaldehyde deterioration test. As a result of SPME, Naphthalene to be used as antiseptic were detected in all of the test conditions. Acetic acid that is VOCs were detected for factor. Moreover as the higher humidity it was, the concentration of chemicals were decreased.

  • The objective of this study is the investigation and analysis of information on the conservation and the sustainable use of coastal wetlands based on the awareness of local residents in Kang-hwa island, Tae-an and Seo-chon. The results are summarized as follows: The degree of the satisfaction on the natural environment is in the order of Tae-an, Kang-hwa and Seo-chon. This order is accorded with the order of the goodness of natural environment. The order for the degree of the satisfaction on the living environment is same as the order for the satisfaction degree on the natural environment. Especially, residents of Seo-chon are not satisfied with the living environment. The residents of all regions are not satisfied with the socio $.$ economic environment. The local resident of Kang-hwa and Tae-an, where natural environment is well-conserved, prefer conservation to development of the region. On the other hand, the local residents of Seo-chon have relatively low preference for conservation of the region. These results show the following consideration for the ideal method of management for the conservation and sustainable development of coastal wetlands. In case of Kang-hwa island, where the, condition the natural environment is well conserved, should be managed with the minimum development with maintenance of the current state must be driven.

  • The growth in human has a close relationship with circumstances and there are two different types of form as a method. One of them Is a great influence of which the environment has a certain effect to human and that is called environmental effect. The other one Is a great reaction of human against the environment which is environmental experience. Human's being loved nature and conservation of nature as a living condition have already processed out for a long time. However, in these days, it is different that a special emphasis on the conservation of nature is being destroyed and it Is perceived the principal of the destruction is human itself. The Museum of Natural Environment has no doubt in a relation with conservation of nature. The main subject of this thesis Is to restore the disappearing beauty in natural environment, an importance of resources in general needs and a change in futuristic perceptions against preservation of the species. Therefore, to produce a complexity in a combination with education and entertainment to a water resource as a main theme is now relieved from its original deteriorated public information center with its simpleness. It Is purposed to secure a cultural space for a community activity and regional peculiarities, dams and lakes, localities of rivers as a main theme to specify their details, to maximize its educational space furtherance with a value as a tourist resource in particular.

  • The habitat characteristics of Aconitum austrokoreense Koidz. were investigated to provide basic data for conservation and restoration. The altitude ranged from 260m to 728m with inclinations of $4-39^{\circ}$. As a result of vegetation survey within natural populations, a total of 147 taxa were identified inside 20 quadrates in 7 natural habitats. The importance value of Aconitum austrokoreense was 23.0% based on the coverage and frequency of the herbaceous layer and sat is more dominant. Species diversity was 1.23, and dominace and evenness were found to be 0.22 and 0.77, respectively. The soil type were silty loam (four sites), sandy loam (two sites) and loam (one site). The average field organic matter was 7.83% and the total nitrogen and pH were 0.35, and 5.69. Correlation analysis between environmental factors and population characteristic showed the correlations between chlorophyll content and slope, flowering rate and soil humidity. Conservation on habitats conditions is important for stable maintenance the flora and the surrounding area including habitats has to be designated a protection area for habitats conservation.

  • This study was conducted to prioritize land purchase in Hwapocheon wetland protection area by reflecting the conservation value of wetlands considering HSI(Habitat Suitability Index) for flagship species. As a result of this study, the flagship species, Oriental White Stork and Been Goose, which can represent the Hwapocheon wetland protection area, were selected through selection criteria and expert feedback. Based on the habitat requirements of the selected flagship species, SI(Suitability Index) for the flagship species was reviewed and the conservation value of wetlands was assessed. The conservation value of the wetlands was divided into five grades from very high to very low. The areas with high conservation value were mainly distributed around wetlands and waters in upstream and downstream of Hwapocheon wetland protection area. The land purchase priorities were divided into five grades by overlapping the thematic maps of the conservation value of wetlands, the economics, and the urgency of restoration. The arable lands which can disrupt wetland ecosystems are analyzed as priority areas where priority purchasing is required. Relatively well-preserved wetlands and areas have low land purchase priorities. This study is meaningful in that biodiversity is considered in land purchase priorities.

  • Conservation of wetlands are important because wetlands are hatcheries for fishes and habitat for migratory birds and mammals. Wetlands also function as a filter for polluted water and material and transition zone for harboring numerous species of plants and animals. This paper reviewed the importance of wetland conservation and policy on management of wetlands in Korea. Wetland Conservation Act(1999) and Maritime Management Act(1999) are two legislation for conservation of wetlands. Wetland Conservation Act is issued by both Ministry of Environment and Ministry of Maritime Affairs and Fisheries. The definition of wetlands are so diverse, but this paper categorized wetlands as both natural and man-made lakes, mud flat areas and inland wetlands. Management application was considered for each wetland categories.

  • As the water shortage has become a noticeable issue due to climate change, forests play an importance role as the provider of water supply service. There is, however, little information about the relationships between the factors used in the estimation of water supply service and coarse pore fraction of forest soil which determines the potential of water supply. To find out whether there would be an amelioration in the scoring system of water supply service estimation, we examined all factors except meteorological one and additionally, analyzed 4 extra factors that might be related with coarse pore fraction of soil. A total of 2,214 soil samples were collected throughout South Korea to measure coarse pore fractions from 2015 to 2020. First, the result of average coarse pore fraction of all samples showed 32.98±6.59% which was consistent with previous studies. And the results of non-parametric analysis of variance indicated that only two of eleven factors that was used in the scoring system matched the results of coarse pore fraction of forest soils. Tree canopy coverage showed no difference among categories, and slope also showed no significance at level of 0.05 in the linear regression analysis. Additionally, the applicability of 4 extra factors were confirmed, as the result of coarse pore fractions of soil samples were different for various categories of each factor. Therefore, the scoring system of water supply service of forest should be revised to improve accuracy.

  • This study focused on the Gaya mural tomb located in Goa-ri, Goryeong-gun, North Gyeongsang Province, Republic of Korea. Environmental factors such as ambient temperature, relative humidity and surface temperature, and microbial distribution on mural tombs were monitored for one year to gather data on the conservation environment of the mural tombs. The average internal temperature difference with reference to the ambient outer temperature was observed to be $11.7^{\circ}C$ for the monitoring period and the internal temperature of the tomb was found to change periodically every one or two months in response to the outer temperature. The highest temperature was observed in September and the lowest in March. The relative humidity in the mural tomb remained constant at 100%. Between December and April, condensation occurred on the ceiling of the main room of the tomb, where the murals are located. On the ceiling of the aisle, the condensation occurred throughout the year. The inside and surface wall were isolated from microorganisms, which could grow when a suitable growth environment suitable is established. Based on microbial growth temperature conditions, risk periods of microbial hazards were established, where in the period from August to October was identified as the most dangerous.
