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.

최근 우리나라의 많은 하천에서 자연 친화적 하천정비가 이루어지고 있으며, 이를 위한 하천정비기법들 역시 다양하게 소개되고 있다. 다양한 기법들은 대상하천이 가지고 있는 특성을 충분히 고려하여 자연 친화적 하천정비를 추진하자는 데 그 근거를 두고 있다. 이에 따라 하천을 구성하고 있는 지형학적 요소와 그 구조 안에서 흐름이 갖는 수리학적 특성, 그리고 하천에서 서식하는 생태학적 조건과 현상들에 대한 분석을 통한 연구가 친자연적인 하천을 조성하기 위한 토대로서 활발하게 진행되고 있다. 본 연구에서는 제방 또는 하안을 유수에 의한 파괴와 침식으로부터 보호하는 역할을 하는 호안에 대한 평가기법을 수리학적, 생태학적 관점에서 연구하였다. 호안은 제방 및 하안의 수리적 안정성을 담보하기 위해 시공되는 하천구조물이며, 그로 인해 자연 생태계와의 조화로부터 이탈될 수 있는 가능성이 높은 구조물이다. 그러므로 자연 친화적 하천정비를 위한 호안의 평가는 반드시 생태적 요소들을 고려하여야 한다. 따라서 본 연구는 자연 친화적 하천정비를 위한 호안의 평가지표 및 기법의 개발에 대한 선행연구로서 현장조사지점 선정과 선정된 조사지점의 세부조사항목들을 활용한 평가방법을 모색하였다. 이는 향후 하천의 호안설계 및 시공을 위한 가이드라인 제시를 위한 초석으로 활용될 수 있을 것으로 기대된다.

The paradigm of the use and management of natural resources is changing. Wise use of natural resources can be achieved by enhancing their conservation value and, at the same time, taking them as an opportunity for regional development. It leads to an idea of pursuing regional development by making good use of natural resources. In this paper, natural resources were classified as living species resources, ecosystem and landscape resources, and non-living resources. The resources were divided into 27 detailed analysis indices. The administrative boundaries of 165 municipalities in Korea were defined as spatial analysis units. Finally, a spatial database of natural resources was built. To classify the regional types, we conducted factor analyses with a detailed index of natural resources and a cluster analysis with the factor value. As the result of the factor analysis, six factors have been deduced as follows: forest resources, landscape resources, coastal ecology resources, inland water resources, landform resources, and ecology visit resources. In addition, the cluster analyses were conducted for the points of the factors drawn. The final classification consists of nine groups, and appropriate methods for each regional development have been suggested. Results of this study will contribute to providing fundamental materials for site selection and objective-setting for regional development policies and planning in consideration of natural resources.

This study attempted an eco-ethical approach to the sporting body, focusing on Toegye's Gyeong. A causes for the conflict between man and nature is a wrong view of nature derived from human desire. Toegye thought that the problem of desire could be overcome through Gyeong. Eco-ethical approaches of Toegye's gyeong thought are possible for the following reasons: First, because Toegye's gyeong is completed in nature. Second, because Toegye's gyeong emphasize human responsibility (consideration) for nature. Third, because gyeong is related to the ability to practice morality. Meanwhile, Toegye understood 'preserving the body well' as self-preservation and at the same time, as the meaning of a natural principle of following the laws of nature. From this perspective, the sporting body has meanings of physical fitness and mental health and at the same time, an aspect of ecological values of understanding man and nature as a single network and following the order of nature. Acquisition of Gyeong through the sporting body suggests the practice of 'gyeongsin (respect for the body)' and 'hwalgyeong (preservation of the ecological environment).' When human beings do physical exercise with nature, they proceed to the stage of building up the virtue of yosan yosu (finding happiness in mountains and water) through nature preserving the ecological environment (hwalgyeong) beyond staying at the stage of gyeongsin.

Wetland is the ecotone between aquatic ecosystem and land ecosystem, and is much valuable in terms of ecology and economic. The stream wetland among inland fresh wetlands occupies the largest area but has been recognized as only a channel not a habitat. The purposes of this paper are to consider the characteristics of natural wetlands formed in the tributary flowing into the downstream reach of Nakdong River and to find its optimal management policy. Natural wetlands in the middle-size streams (2nd${\sim}$3rd order) are large marshlands, and were formed at the places from the mainstream away, because natural wetlands were formed in the reach of longitudinal profiles during the last glacial and the post-glacial period meet in disharmony. In order to conserve these natural wetlands effectively, we should compile the inventories of wetlands and make precise distribution maps. And we should do 'reverse-reclamation' which means the alteration of some farmlands reclaimed from natural wetland into natural wetland ecosystem, and develop the place or the space for wildlife education and ecotourism.

영국 리즈대학과 요크대학의 연구팀은 친환경 유기농장을 유지하는 것보다 기존 농장 주변으로 자연 생태계 지역을 완충지로 두는 것이 식량 생산에 더욱 효과적이라는 연구결과를 냈다. 친환경 유기농업은 상대적으로 수확량이 적어 개간 면적이 넓어지기 때문에 결국 생태계에 악영향을 끼치게 될 것이란 분석이다.

The goal of work is to Metaphysics (the science of human nature and natureal laws) and Ecology of Gosangugokga<고산구곡가>. Gosangugokga is the harmony of nature and human. The fundamental idea of Metaphysics and Ecology are each same. Gosangugokga is the works of Yunsijo(연시조) by the Yulgok(율곡) and formulated ten-lines. Yulgok was Korean famous a Confucian scholar. His thought summarized that is Likizimyo(이기지묘) Litongkiguk(이통기국). Kiballiseung (기발이승). Yulgok was an espeaially emphasize to the harmony of nature and human. Gosangugokga is the appearance of Yulgok's thought. And so, it is possible throughout Gosangugokga was the metaphysical recognize of ecology. The works of a recognition of residence, the rotation of four seasons. the company with life were the metaphysical recognize of ecology in Gosangugokga. The contents of a Gosangugokga is the fundamental idea of metaphysics. Then, that is the closely related to the ecology. Therefore this dissertation studied the Gosangugokga by investigating a relationship between metaphysics and ecology.

We reviewed and compared nationwide surveys conducted in advanced countries (i.e., Japan, Germany, USA, and UK) with those in Korea, including the third Nationwide Survey of Natural Environments, which began in 2006 and will proceed until 2010. Based on this comparative analysis, we suggest alternatives to the nationwide survey of natural environments that are suited to Korea. Given the focus on species abundances and distributions in previous nationwide surveys in Korea, surveys of habitats, ecosystems, and ecoregions are required to more effectively protect biological resources in Korea. Furthermore, their spatial distributions should be mapped using periodical satellite images and aerial photographs. In particular, satellite images can be used to survey species, habitats, and ecosystems. Natural resources monitoring and management specialists are needed to collect various data and improve survey results. The participation of community volunteers is also important to develop an awareness in local residents of natural environment conservation. Independent survey institute (i.e., a 'National Ecosystem Institute') should be established to develop a database and survey scheme for species, habitats, and ecosystems throughout Korea. Moreover, the survey institute could develop natural environmental policy through the data analysis to meet the objectives of the Convention on Biological Diversity. The establishment of a survey institute will allow the completion of a natural environment survey that considers various factors, including physical habitat conditions. This will allow us to detect subtle changes in species abundance and spatial distributions and provide accurate and timely information on natural environments.

본 연구는 자연생태하에서 지속가능한 태양에너지와 생태계작용에 의한 수질개선기법을 개발하기 위하여 생태연못을 설치하여 수질부하가 발생함에 따라 생태연못에 에너지를 순환시켜 생태적 수질정화 기능을 강화하는데 목적을 두었다. 본 연구에서 생태연못(Eco-Pond) 시스템의 수질개선 원리는 수중(유입수)의 침전, 유기산 생성, 메탄 발효, 호기성 산화, 광합성 산소배출 및 병원균 제거 등을 촉진시키기 위한 목적으로 축산농가 및 마을단위의 축산 및 생활하수 유입부에서 생태연못을 두어 수질을 개선하는 공법 즉, 산화조(Oxidation Pond)에 SolaBee 시스템을 결합한 모델을 제안하였다. 에너지 순환장치를 이용한 수질개선 방안으로는 태양열 연못 내에 물순환장치를 만들어 수체를 효율적으로 순환시키고 공기를 혼합시켜 부영양화가 진행되는 연못이 수질을 자연친화적으로 개선시키도록 하였다. 따라서 연구결과 태양에너지는 다른 자연에너지(풍력 등)에 비해서 에너지 밀도는 낮지만 지역의존성이 적고 그 양이 방대하여 21세기 중요한 에너지원으로 사용가능성을 확인할 수 있었다. 본 연구에서 제시된 에너지 순환구조를 가진 생태연못 시스템은 우리나라 중소규모의 농촌 및 축산농가에 보급 될 수 있는 수질개선 시스템이다.
