To evaluate existence value of green area through industrial area worker＇s consciousness estimation, result that achieve is as following. According as green area amount of green area decreases, assessment about existence value of green area decreased. Environment that industrial complex worker can work in agreeable psychology need to increase green area in some form to be formed. Existence of green area enhances conscious value about visual improvement effect such as good environment, seasons change, and green quantity, and is judged that green area is exerting positive effect to consciousness regarding environment improvement effect such as cooling sensation, wind control, and noise decrease.

Fine particulate matter (PM2.5) has been the biggest environmental problem in Korea since the 2010s. The present study considers the value of urban forests and green infrastructure as an ecosystem service (ES) concept for PM2.5 reduction based on satellite and spatial data, with a focus on Seoul, Korea A method for the spatial ES assessment that considers social demand variables such as population and land price is suggested. First, an ES assessment based on natural environment information confirms that, while the vitality of vegetation is relatively low, the ES is high in the city center and residential areas, where the concentration of PM2.5 is high. Then, the ES assessment considering social demand (i.e., the ESS) confirms the existence of higher PM2.5 values in residential areas with high population density, and in main downtown areas. This is because the ESS of urban green infrastructure is high in areas with high land prices, high population density, and above-average PM2.5 concentrations. Further, when a future green infrastructure improvement scenario that considers the urban forest management plan is applied, the area of very high ESS is increased by 74% when the vegetation greenness of the green infrastructure in the residential area is increased by only 20%. This result suggests that green infrastructure and urban forests in the residential area should be continuously expanded and managed in order to maximize the PM2.5 reduction ES.

The purpose of this paper is to estimate economic value of multi-functionality roles including landscape and so on, which grassland in Jeju possesses, using Dichotomous Choice Contingent Valuation Method (DC-CVM). Grassland is life cultural heritance of regional residents in Jeju. It has functions like development of favorable landscapes, maintenance of cultural heritage, and recreation/relaxation. Expectation from regional visitors shows that the existence and inheritance value of grassland is higher than we expected. According to the research that we had done from the people that had agreed to contribute grassland. moreover the public commercial value of grassland was not only $397{\sim}419$ billion won but also it will increase an economic gain in every year in Jeju. Therefore, preserving grassland that has multi-functional roles and values can lead to huge economic value in the future in Jeju. Moreover, farm households which are located in the grassland conservation area would be supported $15{\sim}31$ billion won in every year for grassland conservation but it is only $4{\sim}8%$ of the economic value of grassland i.e. $3,971{\sim}4190$ billion won. Thus, grassland preservation policy and plan can raise green-tour commercial value of Jeju area as a long-term inside measurement. Those will have to be propelled continuously.

The purpose of this paper is to estimate the economic value of Multi-functionality Roles including landscape and so on, which traditional stone fences in Korea possess, using Dichotomous Choice Contingent Valuation Method (DC-CVM). The stone fences is life cultural heritance of regional residents. It has functions like Development of Favorable Landscapes, Maintenance of Cultural Heritage, and Recreation/Relaxation. Expectation from regional visitors shows that the existence and inheritance value of the stone wall is higher then we expected. According to the research that we had done from the people that had agreed to contribute the stone wall. moreover the public commercial value of regional tradition stone was not only 2,900 billion won but also it will increase an economic gain in every year. Therefore, preserving the stone wall that has Multi-functional Roles and values can lead to huge economic value in the future. But farmhouses in the stone wall conservation area are being supported 9 billion won in every year. This is only 0.03% of the income that farmhouse earns per year. Thus, stone wall preservation policy and plan can raise green-tour commercial value of inland area as a long-term inside measurement. Those will have to be propelled continuously.

The purpose of this paper is to estimate the economic value of Multi-functionality Roles including landscape and so on, which the stone fences in Jejudo possess, using Dichotomous Choice Contingent Valuation Method(DC-CVM). The stone wall is life cultural heritance of Cheju islanders. It has functions like Development of Favorable Landscapes, Maintenance of Cultural Heritage, and Recreation/Relaxation. Expectation from Cheju visitors shows that the existence and inheritance value of the stone wall is higher then we expected. According to the research that we had done from the people that had agreed to contribute the stone wall, the result was that the public commercial value of Cheju tradition stone will increase every yew(2006: 367 billion won, 2011: 437.1 billion won). Therefore, preserving the stone wall that has Multi-functional Roles and values can lead to huge economic value in the future. But farmhouses in the stone wall conservation area are being supported 6 million won every year. This is only 10% of the income that farmhouse ems per year. Thus, stone wall preservation policy and plan that can raise green-tour commercial value of Cheju Island of long-term inside measurement will have to be propelled continuously.

본 연구는 한국 남해안 동부해역의 해조군집 특성을 정량적으로 분석하고, 그 변동을 파악하기 위하여 일차적으로 이 해역을 대표 할 수 있다고 보여지는 경남 통영군 욕지면 연화도에 선정한 8개 지점에서 1984년 12월부터 1986년 1월사이에 수행되었고, 그 결과는 다음과 같았다. 1. 출현 해조류는 남조류 2종($1.8\%$), 녹조류 18종($15.8\%$), 갈조류 25종($21.9\%$) 그리고 홍조류 69종($60.5\%$)으로 모두 114종이었다. 2. 홍조류 종수에 대한 갈조류 종수의 비 (R/P 값)은 2.8로 남해안 연안쪽보다 높게 나타났다. 3. 해조류의 기능형군별 구성비는 계절적으로는 봄 겨울에는 사상형과 막상형이 우세하고, 여름과 가을에는 직립분기형과 다육질형이 우세하였다. 그리고 지점별로는 파도가 적은 내만쪽에서 막상형과 각상형이 우세하고, 파도가 강한 쪽에서 직립분기형과 다육질형이 우세하였다. 4. 군집의 유사도 분석 결과, 유사도 $30\%$ 수준에서 봄에는 5개군, 여름, 가을 및 겨울에는 3개군으로 나타났고, 이들은 파도의 강약, 계절풍의 영향정도에 따른 특성을 갖는 것으로 추정되었다. 5. 전 조사기간을 통하여 전 지점에서 중요도 10이상인 종은 Porphyra suborbiculata (30.1), Corallina pilulifera (27.8), Hizikia fusiforme (27.7), Sargassum thunbergii, (27.5), Undaria pinnatifida (22), Ishige okamurai (20.6), Chondria crassicaulis (20), Ulva pertusa (16), Pseudulvella consociata (15.7), Urospora penicilliformis (15), Sargassum sagamianum (14.9), Caulacanthus okamurai (12.8), Gloiopeltis furcata (12.7), Sargassum micracanthum (11.7), Myelophycus simplex (11.2) 이었고, Melobesioideae가 25.7이었다. 6. 무절석회조 순군집의 빈도 및 피도는 각각 $44.6\%$ 및 $75\%$였고, 무절석회조와 다른 해조가 혼생하는 군집의 빈도 및 피도는 각각 $55.4\%$ 및 $65.8\%$로서 혼생하는 군집의 피도가 약간 낮았다. 7. 무절석회조와 다른 해조류가 혼생하는 군집의 출현빈도나 피도가 높은 종은 Corallina pilulifera, Gelidium amansii, Sargassum sagamianum, S. thunbergii, Hizikia fusiforme, Laurencia spp. 등으로 기능형으로는 주로 직립분기형이나 다육질형이었다. 8. 점심대지역에서의 무절석회조의 높은 피도율은 명확하지는 않으나 식해의 영향 때문인 것으로 추정되었다.
