In South Korea, the conflict between development and conservation policy still exist among government ministries, and conventional development plan often has priority over conservation policy. Establishment of sustainable development and comprehensive management policy employing the results of ecosystem service studies are highly warranted, but researchers in South Korea are still limited and often misuse the concept of ecosystem services. Thus, we aimed to introduce the concept of Ecosystem Service (ES) and related terminologies such as Social-Ecological Systems (SESs), ecosystem function, trade-off, and human well-being in this paper. Additionally, this article reviewed and arranged key approaches in ES studies as follows: 1) field works, 2) mapping ecosystem services, 3) valuing ES, 4) quantifying trade-offs between ES and 5) understanding SESs. Based on those results, we suggest that field works for basic information have the first priority to be conducted among ES studies. Once basic information is sufficiently accumulated, researchers can perform applied ES research with accuracy. Finally, results of ES studies conducted by five approaches allow decision makers to consider both natural system and society simultaneously, and hence the results can be utilized for sustainable development and conservation policy based on ecosystem-based management.

The purpose of this study is to evaluate the applicability of Ecosystem Service Matrix method in Songnisan and Hannamgeumbukjeongmaek Boeun-gun area. The assessment was carried out with 25 land cover types by 7 ecosystem values. The research area was divided by 30m x 30m cell unit and the each cell value was classified into 5 grades. The total number of cell under the investigation was 433,910 units in Songnisan and 84,975 in Boeun-gun. Class I and II area were widely spread and Class V area is narrowly distributed inside of Class III area in Songnisan. I area, II area and separately managed zone belong to Ecological Zoning map and Environmental Conservation Value Assessment Map(Environment + Ecology) were assessed Class I in Ecosystem service matrix. In conclusion, Ecosystem Service Matrix assessment based on land cover map is a rapid assessment methodology which reflecting ecosystem functions in a larger area. If it is supported with more ecosystem functions, the more precise nature value can be calculated.

This study examined the effective uses of an ecosystem service value assessment in the fields of rural planning and development through archiving and reviewing/analyzing existing concepts, evaluation methods and prior examples of Ecosystem services. Based on land cover analysis, this study evaluated the usability changes in the ecosystem service value for a period spanning 1975 to 2000. The results from the countrywide data survey (with an exception of Jeju island) showed a 33.15% decrease in ESV by 2000. The total ESV represented 5,385 million USD in 1975, and 3,600 million USD in 2000 of the study area. In addition, the ecosystem service value with a scale of metro cities and provinces was also examined. The ESV of most regions decreased by 2000, but Daejeon and Kyeongnam, and Kyeongbuk provinces increased. The trends of year to year changes in the ESV were very diverse throughout the country. Jeonnam showed the smallest decrease, 747 million USD, which is 59% of the ESV in 1975. Nevertheless, the despite the regional differences in available natural resources, the natural resource assets value is ultimately determined by rural development policies and regional economic attributes. Therefore, an ecosystem service must be considered as an important criterion for rural planning and development policy.

최근, 새천년생태계평가(MA: Millenium Ecosystem Assessment), 생태계와 생물다양성의 경제학(TEEB: The Economics of Ecosystems and Biodiversity) 등의 체계에 따라 생태계서비스를 평가하는 연구가 활발히 이루어지고 있다. 그러나 기존 대부분의 연구에서는 생태계기능 평가량에 화폐적 가치를 곱하여 생태계서비스를 평가하고 있어 생태계서비스와 관련된 환경 및 사회경제적 조건을 반영하지 못하고 있다. 본 연구에서는 자연 및 사회경제적 요소를 반영한 생태계서비스 평가방안을 제시하고자 하였다. 우선, 수원함양기능을 InVEST의 Water Yield 모형을 통해 평가하였고 수원함양기능에 강수량과 인구를 반영하여 수원함양의 생태계서비스를 평가하였다. 평가결과, 토지피복, 토양 등의 자연조건을 반영한 수원함양기능과 강수량 및 인구 등의 기후 및 사회경제적 인자를 추가적으로 고려한 생태계서비스의 공간분포는 서로 다른 양상을 보였다. 즉, 같은 수원함양기능을 보인 지역이라도 강수량이 적고 인구가 많은 지역에서 수원함양의 생태계서비스가 높은 것으로 나타났다. 본 연구를 통해 수원함양의 생태계서비스는 수원함양기능에 추가적으로 기상 및 사회경제적 인자를 고려하여 평가되어야 한다는 것을 제시하였으며, 평가과정은 다른 분야의 생태계서비스평가에 유용하게 활용될 것으로 기대된다.

Since the Millennium Ecosystem Assessment Report was published in 2005, the conflict between development and the preservation of the ecological environment has turned to paying attention to value assessments in rational decision-making. In recent years, the concept of ecosystem services has been recognized as a viable one for making significant decisions. However, a trade-off between increase and decrease occurs between the ecosystem services sub-categories (cultural service, regulating service, supporting service, and provisioning service), for which research centering on target sites is needed. To this end, the present study aims to investigate the trade-off relationship between service categories to search for reasonable decision-making strategies. As the research method, a survey was conducted using the translated version of SoIVES(Social Value for Ecosystem Services) 3.0 questionnaire of the United States Geological Survey. The research findings demonstrate the economic value, based on the derived monetary value of each service category, the economic value of the target site was compared among landscape aesthetic value 8,050,000 won, recreation value 6,750,000 won, biodiversity value 4,610,000 won, healing value 3,970,000 won, life-sustaining value 2,090,000 won, and productive value 220,000 won. And then the primarily recognized value criteria of the Tancheon ecosystem services illustrate landscape aesthetic and recreation value. Besides, this study illustrates visualized trade-off relationships based on user perception, and the derived relations illustrate the trade-off relationship between the cultural service, regulating service, supporting service, and provisioning service, as well as relationships between the components of the sub-categories.

We first develop a value ecosystem framework to model the SDP(Service Delivery Process) of web services. Since the web service has been evolving from the basic web architecture (e.g., traditional world wide web) to a prosuming platform based on virtualization technologies, the proposed framework of the value ecosystem focuses on capturing the key characteristics of SDP in each type of web services. Even though they share the basic elements such as PP(Platform Provider), CA(Customization Agency) and user group, the SDP in the traditional web services (so-called Web1.0 in this paper) is quite different from the most recent one (so-called Web2.0). In our value ecosystem, users are uniformly distributed over (0, ${\Delta}$), where ${\Delta}$��represents the variety level of users' preference on the web service level. PP and CA provide a standard level of web service(s) and prosuming service package, respectively. CA in Web1.0 presents a standard customization package($s_a$) at flat rate c, whereas PP and CA collaborate and provide customization service with a usage-based scheme. We employ a multi-stage game model to analyze and compare the SDPs in Web1.0 and Web2.0. Our findings through analysis and numerical simulations are as follows. First, the user group is consecutively segmented, and the pattern of the segmentations varies across Web1.0 and Web2.0. The standardized service level s (from PP) is higher in Web1.0, whereas the amount of information created in the value ecosystem is bigger in Web2.0. This indicates the role of CA would be increasingly critical in Web2.0: in particular, for fulfilling the needs of prosuming and service customization.

본 연구에서는 생태계서비스 중 수질조절 서비스 가치 평가를 수행하기 위해 생태계서비스 수질조절 서비스의 물리량을 정량적으로 평가하였고 이를 이용하여 경제적 가치를 평가하는 방안을 마련하였다. 과거에 비해 수질이 개선되고, 어류 등 수생생물의 종과 수가 늘었더라도, 그 요인은 생태계의 수질조절 서비스와 수질개선를 위한 환경기초시설의 확충, 수질환경규제 등 복합적인 요인에 기인된다. 그 중 생태계 조절서비스 가치에 대해 정량적으로 산정할 수 있는 방법을 모색하는 것을 연구의 목적으로 설정하였다. 본 연구에서 생태계의 수질조절 서비스를 정량적 가치를 규명하기 위해 수질오염총량을 활용하는 방법에 대해 제안하였다. 이와 함께 생태계의 수질조절 서비스의 산정된 물리적 수질조절량에 처리단가를 곱함으로써 경제적 가치 평가 방안을 제시하였다. 마지막으로 개발된 평가기법을 이용하여 낙동강 수계에 BOD, T-P 항목에 대해서 생태계 수질가치를 평가하였다.

The interest on rural ecological landscape has recently grown on the part of policy makers for rural development. While considerable efforts and resources have been invested to preserve and utilize rural landscape, we still lack a systematic means to quantify and evaluate ecosystem service value of the rural landscape and management status. So this study suggests rural ecological landscape management indicator considering ecosystem service value. It consists of 28 criteria and 107 subcategories, which can be applied to rural village. And We have applied ecosystem service value assessment and resident's management status on three villages, Moondang village, Yonggye village, and Sesim village.
