The purpose of this study was to investigate the effect of the value perception of ecotourism on the behavioral intention and satisfaction of university students. The results of the study are as follows. First, it was found that all ecotourism value recognition factors, such as cognitive value, emotional value, and functional value, had a positive(+) effect on satisfaction. Second, it was found that all ecotourism recognition factors, such as cognitive value, emotional value, and functional value, had a positive(+) effect on behavioral intention. These results show that the higher the awareness of ecotourism is, the higher the satisfaction and behavioral intentions of ecotourism are, but the functional value made up of services, quality, and programs has relatively less influence than other factors. Therefore, various marketing strategies and educational programs such as the development of accessible weekend products and development of sustainable light-emitting products that can respond to each ecotourism value recognition factor that affects the ecotourism product satisfaction and behavior intention should be developed.

강 하구의 민물과 바닷물이 만나 형성되는 기수역 생태계는 독특한 환경적 가치를 지니고 있다. 낙동강 하구는 우리나라의 대표적인 철새 도래지로 풍부한 생태자원을 지닌 곳이지만, 하굿둑 건설로 기수역이 사라진 이후 기수역 생태계가 갖고 있는 고유의 생태적인 특성이 감소하였다. 한편, 낙동강 하굿둑 건설은 염해피해 방지 및 부산, 울산, 창원 등의 지역에 추가적인 용수공급을 가능하게 도왔다. 이에 낙동강 기수역 생태계 복원을 위한 하굿둑 개방과 용수공급 및 염해피해 방지 등을 위한 하굿둑 운영에 대한 논의가 지속되어 왔다. 낙동강 하구관리에 대한 합리적인 의사결정을 위해서는 하굿둑 건설 및 운영에 따른 편익과 동시에 낙동강 하구 기수역의 생태 환경적 가치도 함께 고려해야한다. 이에 본 논문에서는 낙동강 하구의 기수역 생태 복원에 초점을 맞추어 이와 관련된 환경적 가치를 조건부 가치측정법이라는 경제학적 기법을 적용하여 추정하고자한다. 전국 800가구를 무작위로 추출하여 일대일 개별면접을 통해 낙동강 기수역의 생태복원에 대한 지불의사액을 조사하였다. 이 정보는 낙동강 하구관리에 대한 의사결정시 활용할 수 있다.

The goal of current study is to carry out comparative analysis on the relationship between nature perspectives and their corresponding utilities by taking integrated approach combining economic values with environmental ones. The results are as follows. First, empirical evidence shows that the structures of happiness function differ according to nature perspectives. The anthropocentric-nature perspective is centered on economic value. Whilst, environment and social trust play an statistically insignificant role in deciding happiness levels. Secondly, the eco-centric perspective possesses a multi-facted structure of happiness function composing of income, environment, and social trust. In this vein, it is no reasonable behavior, from happiness maximization view, to focus on economic value vis-a-vis use value.

In this study, we developed a method to assess quantitatively the amount and the economic value of water quality regulating service of ecosystem services. Numbers of species and aquatic organisms such as fish increased because of the improved water, but it was due to complex factors such as water quality regulation services of ecosystems, installation of environmental facilities for water quality treatment, and water quality regulation. Therefore we sought ways to quantitatively estimate the value of ecosystem regulation services. In this study, we propose a method to estimate the quantitative value of water quality regulation service of ecosystem by utilizing the total amount of water pollution. In addition, the economic value evaluation method was proposed by multiplying the estimated the quantitative value of water quality regulation service of ecosystem by the unit cost per unit capacity. Finally, the ecosystem water quality regulation service was estimated by using the evaluation method for BOD and T-P in Nakdong river watershed.

More than half of all the tidal flats and islands in South Korea are located in Jeonnam. Shinangun accounts for a large amount of these tidal flats and island. This study assessed the value of ecosystem services for 14 administrative units (2 'eup' and 12 'myeon') that have around 1,000 islands in Shinangun, using the method described by Costanza et al. (1997). The assessment involved examining the land use types in Shinangun in relation to ecosystem services value. The finding showed that the tidal flat areas had the highest value of ecosystem services in most of the islands of Shinangun, in particular in Aphae-eup and Jido-eup. The study illustrates how quantitative analysis of land use patterns can help local governments like Shinangun to formulate policy for conservation and sustainaable use of ecosystem services. Especially, tidal flat areas are unique and fragile ecosystem, so it is very importat to make strategies for sustainable development in bioculturally diverse areas. Some suggestions regarding landscape planning in Shinangun are provided.

This study estimates the willingness-to-pay (WTP) for avoiding the destruction of a first-grade ecological area by means of contingent valuation method. Specifically, we employ the dichotomous choice technique along with the follow-up questionnaires. Our analysis implies the yearly WTP per household for avoiding the destruction of the ecological area of 100,000 pyongs is 8,898 won with the 95% confidence interval of 6,611~11,976 won. We estimate the asset value of that area to be 1,707 billion won with the 95% confidence interval of 1,269 to 2,298 billion won. We also decompose the total value of the area into the value of direct (22%) and indirect (38.8%) use, the option value (19.9%) and the conservation value (21.3%). Although using these data for SEEA (the system of integrated environmental economic accounting) is bound by certain restrictions, one could employ our empirical findings as advisory information for decision making in the process of prior environmental review or for assessing the environmental impact.

환경의 가치, 특히 물의 가치는 시대와 함께 변화하고 있다. 그동안 국내 하천관리는 환경적 측면보다는 이수와 치수에 보다 초점이 맞춰져 있어, 하천 고유의 수생태계 서비스기능 유지에 필요한 용수의 확보에 정책적인 배려가 부족하였다. 그러나 최근 소득수준이 향상되고 환경개선에 대한 관심이 늘어나면서 물관리에 있어 이용뿐만 아니라 환경측면을 고려한 지속가능한 하천관리에 대한 정책적 관심이 높아지고 있다. 이에 하천 수생태에 대한 정책 역시 과거보다 강화되고 있는 추세이며, 최근 물환경보전법 공포를 통해 수생태건강성 유지를 위한 환경생태유량에 대한 법적 근거가 마련된 바 있다. 실질적인 환경생태유량 공급 정책방안 마련을 위해 환경생태유량 공급이 하천 수생태에 주는 효과에 대한 편익 정보를 산정해볼 필요가 있다. 이에 본 연구에서는 환경생태유량 공급효과에 대한 편익을 산정해 보았으며, 이를 위하여 대표적인 비시장재화 가치평가법인 선택실험법을 적용하였다. 한편 환경생태유량 공급효과에 대한 많은 연구에서는 환경생태유량 공급효과를 하천의 주요 어종 관련 지표를 통해 나타내고 있다. 이에 본 연구에서도 환경생태유량 공급에 대한 편익산정시 하천고유어종 변화, 하천 어종 수 변화, 외래어종 변화의 3가지 속성에 대한 한계지불의사액을 추정하였다. 본 연구결과는 환경개선을 위한 정책수행, 특히 수생태계 환경개선을 위한 정책결정시 기초자료로 활용될 수 있을 것으로 판단된다.

This study aims to estimate the values of freshwater ecosystem services from demand and supply perspectives. From demand side, unit-values of ecosystem services are derived from Environmental Valuation Information System (EVIS) and aggregated to 5 main watersheds in Korea. The derived unit-values are based on the willingness to pay estimates per household from stated preference methods. The nation-wide average total values of water quantity supply, water purification, and natural disaster control are estimated as 501.2, 410.4, and 242.4 billion won/year, respectively. From supply side, we examine the direct and indirect public expenditures (or investment) in 2013 to improve freshwater ecosystem services by the government. The total sum of government expenditures corresponds to 8,882 billion won in 2013, where 12.9, 81.3, 0.3 and 5.3% are spent to improve provisioning, regulating, supporting and cultural services, respectively, indicating that most efforts are concentrated in enhancing regulating services.

The riverine wetlands located in the riverside bring about social conflicts through confrontation between flood control value through flood control project and ecological preservation value of riverine wetland. In this study, we identified the importance of both values through analysis of economic feasibility of flood control and ecological values of riverine wetland, and tried to suggest management plans for riverine wetland considering both of flood control safety and ecological preservation through these results. For this, we calculated the expected annual flood damage of Imjin River using the multi-dimensional flood damage analysis(MD-FDA), and calculated the total value of riverine wetland using the contingent valuation method(CVM) to estimate preservation value of riverine wetland. The result of the analysis shows that the Imjin River needs flood control project and the ecological preservation of riverine wetland is also important. Therefore, the establishment of the management plan for protecting riverine wetland is also needed. As a result, the Imjin riverine wetland was classified as the area where sedimentation continues to take place, and the flood water level to rise. On the basis of the analyzed results, it is judged that the Imjin River needs flood control for public safety and ecological consideration for ecosystem preservation in the river improvement project. So, the stepwise river improvement is desirable to protect riverine wetland and minimize ecosystem disturbance. The results is expected to be made good use as the basic study for establishment of institutional river management plans considering flood control project and riverine wetland preservation in the future.
