This study was carried out for the purpose of presenting basic data bases for conservation and management measures of Ecological and Scenery Conservation Area in Bongsan. The analysis results of the actual vegetation showed that rate of vegetation cover were composed of 72.3% of Robinia pseudo-acacia Forest, 10.7% of Sorbus alnifoila Forest, and Sorbus alnifoila was founded as a dominant woody plant species in the Core Zone of Bongsan Ecological and Scenery Conservation Area. To investigate the vegetation structure of Sorbus alnifolia Community in Bongsan Ecological and Scenery Conservation Area, twelve $100m^2$ sized plots were set up in Bongsan. According to the classification by TWINSPAN, the communities were divided into the three groups of Sorbus alnifolia Community, Pinus koraiensis Community and Robinia pseudo-acacia Community, To analyze annual diameter growth rate for major tree species, nine sample trees from research plots were measured. Expected ages of Sorbus alnifoila trees were 27~37years, Robinia pseudo-acacia trees were 17~26 years, Pinus koraiensis, Pinus rigida, Prunus sargentii, and Quercus mongolica trees were 27~38 years. As a result, annual diameter growth rates of Robinia pseudo-acacia and Pinus rigida tended to remarkably decreased, Sorbus alnifoila had the wood on inter-specific competition of the woody plant species. Importance values of Sorbus alnifoila in the three layers of Sorbus alnifoila communities were evenly high.

This study aims to evaluate the potential of pro-environmental application(PEP) in streams conceptualized ecological conservation and recreational use to be in harmony with. The main content of research are to clarify the PEP, to establish the evaluation model, and to evaluate 3 streams(Dongchon, Seokhyunchon, Okchon) in Sunchon city. Researchers introduced 12 evaluation items(water quality, water quantity, vegetation-water area, vegetation conservation, streamscape, neighborhood landscape, stream width, optimum area, nearby landuse, facility in stream, distance from user, obstacle to acces) by 5 scales to evaluate the characteristics of natural and artificial factors in stream area and nearby area. Also to decide the weight of items, researchers surveyed the opinion of 22 landscape architects experienced stream-plan through delphi method. Lastly the pro-environmental potential on streams were calculated by the ecological potential and recreational potential indices to be standardized and indicidual sections in streams were divided 5 grades on the basis of PEP. The result of this study are as follows; 1) The evaluation model of PEP was constructed by 4 steps, such as the decision of weight, the measurement of scale, the calculation of potential indices, the gradation of individual sections in streams. 2) The ecological potential were highly influenced by natural factor such as water quality, vegetation conservation, vegetation-water area, but on the other hand the recreational potential were influenced by optimum area, distance from user, water quantity, obstacle to access. 3) The factors such as vegetation conservation, optimum area, nearby landuse, distance from user were function as discernment factors to evaluate relatively ecological and recreational potential. and water quality, water quantity, vegetation -water area, neighborhood landscape were acted as important items to decide PEP.

Cultural heritages are damaged by surrounding several environmental factors. Main factors are temperature, humidity, light, atmosphere and indoor pollutant, organism, etc. Therefore, to prevent damage of cultural heritage from such environmental factor, conservation environment monitoring becomes more important. Indicator is one of the simple method for environment monitoring. It can be used without expensive and complex equipments. However, it should be performed scientific examination for application to cultural heritage. In this study, some Temperature Indicators were chosen and reliability assessment was carried out for application to cultural heritage. Brightness($L^*$) is selected for reliability assessment factor. As a result of lab test, Temperature Indicators were not influenced greatly in humidity change. When they were exposed to setting temperature, the color was changed in setting temperature area and ${\pm}2^{\circ}C$ part of setting temperature. Especially brightness value was high in setting temperature area. Also, Temperature Indicators were stabilized after about 16 minutes when were exposed to temperature difference of $10^{\circ}C$ and when temperature difference with exposure environment is smaller, stabilization time shortened. Therefore, it is a possible to confirm that selected Temperature Indicator is reliable product through measurement of color difference value and naked eye observation.

The study is conducted to establish the National Protected Areas Integrated System(NPAIS) which includes National Protected Areas(NPAs) and other conservation measures in terms of effective ways for biodiversity conservation. Additionally, it is carried out to evaluate progress toward quantitative expansion goals in Aichi biodiversity Target 11. The NPAIS consists of NPAs and other effective area-based conservation measures(OECMs). There are two different types of OECMs. OECMs type I, including water-source protection Areas(WPA), riparian zones(RZ), fishery-resource protection zones (FPZ), and urban natural park zones(UNPZ), is a potential protected area which is recommended to be incorporated into the NPAs for effective management. OECMs type II means development restriction zones(DRZ), natural recreation forests(NRF), and buffer zones for Korea national arboretum(BKNA). As a result of evaluating the quantitative expansion goals of the NPAIS, terrestrial and inland water protected areas exceed 17% of the quantitative goal in Aichi biodiversity Target 11. The larger the area of individual OECMs and the lower the degree of overlap with NPAs, the higher the contribution of them to the terrestrial and inland water protected areas. DRZ contributes to enlarge more than 3% of quantitative expansion. And RZ and NRF contribute more than 1%. The marine protected areas are expanded by $1,425km^2$ through FPZ, but the expanded area is very small as comparing with the total marine area. It adds only 0.321% to the quantitative expansion. The rest of OECMs also has very poor quantitative expansion contributions in the marine area. Consequently, the NPAIS is effective for quantitative expansion of land areas, but not for marine areas.

In order to analyze the effect of environmental protection on wind energy dissemination quantitatively, the onshore wind resource potential is estimated using Environmental Conservation Value Assessment Map and Korea Wind Resource Map. The onshore wind resource potential of 11 GW is calculated if wind farm development is prohibited within Class 1 area of Environmental Conservation Value Assessment plus 500 m buffer area. Therefore it is worried that environmental protection would be a practical barrier of accomplishing 4,155 thousand TOE target of wind energy dissemination until 2030.

For both a healthy environment and sustainable development, we frame a habitat assessment method, concerning biodiversity and physical characteristics. With the method, we set up and extract conservation areas from Peace Valley Resort Development Areas which can function as habitats. Absolute and relative assessment items which are the size of area, habitation of species with conservation value, distribution of communities, functions of habitats, ratio of non-native plants, connectivity of habitats, vegetation layers of forests and age of forests, and water systems are considered on newly extracted conservation areas, and the habitat value assessment was calculated on the items in a 3-point scale. By comparing and examining 3 existing proposals for extracted conservation areas, we assess existing proposals, make an alternative proposal, and try to verify the possibility of applicability to extracted conservation areas. Proposal A and C must not be adopted since almost all conservation areas would be developed in the proposals. Proposal B, consisting of 53% development areas and 47% non-development areas, does not have enough development areas, so high density building arrangements should be encouraged in order to preserve conservation areas. Therefore, proposal B would be the best in ecological terms among the 3 proposals, if 3 conditions are considered : 1) new extracted conservation areas should be conserved; 2) 10~15m wide green-zones on both sides of the water system, which can play a role as ecological corridors, should be considered in development areas; 3) building arrangement should not interrupt the ecological corridors.

Heritage resources have become important social assets as the global interests in heritage tourism increased. Utilization of heritage as unique tourist destination has positive effects on regional economy, which in turn plays an important role in heritage conservation. However, it was found that the essential quality of heritage resources has been degraded and even destroyed when excessive use was permitted. This undesirable side-effects of heritage tourism have led to the growing concern for sustainable tourism that can contribute to both utilization and conservation of heritage. In order for sustainable tourism to be effectively implemented, it is crucial for visitors to be aware of the need for heritage conservation because they are the most important consumers of the heritage. The purpose of this study was to suggest some basic information for sustainable tourism by investigating visitors' evaluation of conservation and use values of heritage resources. The study sites were the two Korean traditional temples(Sokrisan Bubjusa and Naejangsan Naejangsa) and contingent valuation method was used. 390 visitors in Bubjusa and 308 visitors in Naejangsa participated in the questionnaire survey. From the results, sustainable tourism is possible in such heritage areas as traditional temples because the participants had relatively balanced values for heritage conservation and use. The WTP for natural conservation value was found to be highest in both temples; visitors may be more agreeable with the heritage conservation plan if the sustainability of natural resource is emphasized. Also, the use value of heritage could be influenced by the tourism utilization of the area where the heritage was located. If there are no other famous tourist destinations except the heritage in the area, additional plans to develop alternative destinations should be prepared in order to formulate the agreement on the need to protect the heritage among visitors, local communities, and government.

Biotop map can be utilized for nature conservation and assessment of environmental impact for human activities in urban area. High resolution satellite images such as IKONOS and KOMPSAT1-EOC were interpreted to classify land use, hydrology, impermeable pavement ratio and vegetation for biotop mapping. Wildlife habitat map and detailed vegetation map obtained from former study results were used as ground truth data. Vegetation was investigated directly for the area where the detailed vegetation map is not available. All these maps were combined and the boundaries were delineated to produce the biotop map. Within the boundary, the characteristics of each polygon were identified, and named. This study investigates the possibility of biotop mapping using high resolution satellite remote sensing data together with field data with the goal of contributing to nature conservation in urban area.
