  • Forest ecosystem provides variety goods and services for human being. Unlike goods, forest ecosystem services could not be easily priced by market mechanism. This uncertainty has been caused to conflict in decision-making related forest ecosystem services. Quantification of forest ecosystem services is required to understand the importance of ecosystem services and their contribution to decision-making. As a growing concern of climate change, it is necessary to quantify and calculate carbon storage and sequestration in forest. In this study, for quantifying carbon storage and sequestration, we compared scale, output, input data availability of the models and analyzed the applicability of the models to Korea. The results of this study show that most models are applicable for quantifying carbon storage and sequestration. However, relatively few models are applicable for other regulating services (air quality regulation, flood mitigation, erosion control, water quality, etc.) of forest. This study would be helpful for quantifying regulating services of forest ecosystem research.

  • The ecological crisis today can be seen as a result of modernity which has been developed on the Cartesian dualism of subject/object, and of human being/nature, and thereby has huts objectified and subjugated nature through science and technology New environmental ethics hence should be developed urgently against modernity and to overcome the present ecological crisis. This paper aims to consider some implications for ecology and environmental ethics in the post-structurists'arguments struggling against modernity to formulate new frameworks of discourse and politics, and to examine a possibility to theorize environmental justice on the basis of postmodem ecology. For this purpose, this paper first looks on ecological arguments and implications for environmental ethics in post-structuralism, then tries to gain prominent ecological insights, focusing on ethology and 'rhizomatic naturalism'in the philosophy of Deleuze, and finally interprets both bioregionalism as a theory of 'difference' from postmodern point of view and Deleuze's ecology in terms of symbiosis and difference, in order to conceptualize environmental justice.

  • Many ecosystems in Korea are currently managed by government organizations. Thus, public managers' decision-making has great influence on the management of ecosystems in Korea, and their decision-making could influence the matter of whether the ecosystems of Korea are managed effectively. This paper regards the goal of management of ecosystems as securing the sustainablilty of target ecosystems, and investigates public managers' decision-making and their psychological attitude on the management of ecosystems. Basically, managerial activities on ecosystems have uncertainties and usually public managers utilize the knowledge of law, science, intergovernmental relations, and local governance as their references for decision-making. To elucidate public managers' managerial decision-making on ecosystems, this paper adopts some psychological theories in explaining the judgment of human beings under uncertainties. Effective ecosystem management by public managers can be judged by how public managers adopt and utilize all of the above mentioned four kinds of knowledge on ecosystem management. An important factor in order to let them utilize the four kinds of knowledge is policy support. Therefore, as conclusion, this paper recommends some relevant policy measures that can support the ecosystem management of public managers.

  • The disposition of ecotourism was surveyed form October 5 to 22 in 1996. 600 persons were participated from 5 big cities including Seoul in Korea. Of those individuals, 48% were males, 52% were females, 50% of respondents reported that they had gone as far as college, and 38% were 20 years of age. Most percentage of respondents (72%) were not satisfied from their leisure behavior in their daily life, 60% of respondents had a chance to visit outdoor recreation areas per month. The most respondents(75%) didn't hear the concept of ecotourism, but they recognized necessity of the ecotourism development. There was a tendency in the sample for high disposition of ecotourism subjects to be more likely to intend to interest in environmental problems, and participate to environment movement. They were very interested in ecotourism. The differences existed in ecotourists' dispositions of ecotourism, according to their scio-economic characteristics. The potentional ecotourists' intentions of visiting eco-park had strong relationships with the disposition of ecotourism.

  • This study aimed to find out the formation of ecologically educational place identity of nature trails in national parks, which elementary school students to adults can understand, by analyzing the connectivity between characteristics (signs) of nature trails and elementary science environment-related key concepts and the domain of ecological education in the course of environment and by developing a semiotic interpretation model of place identity based on Barthes's semiotic theory. When analyzing correlations between the interpretation board-focused surrounding environment of nature trails and the content system of ecological education, this study found out that it showed the highest connectivity with the domain of 'System of Ecological Environment'. When analyzing the formation of place identity of nature trails in terms of semiotics, this study discovered that geographical locations or landscapes, artificial environments and physical elements as characteristics of surrounding environments mostly acted on the formation of placeness. Besides, it was found that both knowledge and attachment elements equally could act on the formation of a sense of place. Being likely to develop through interaction between placeness and a sense of place, place identity was mostly composed of behavioral internal stages and sympathetic internal stages. To diversify the formation of place identity, however, this study found it necessary to develop environment education projects and create surrounding environments and interpretation boards with the environmental uniqueness of nature trails reflected much more.

  • 전국 주요 산단 지역에서 현재 유통되고 있는 화학물질의 스크리닝 수준에서의 생태 위해성 평가를 수행하고, 체계적인 위해도 분석 시스템을 구축하기 위한 수생 및 육상 생태계가 통합된 생태 위해성 예측 모형을 개발하였다. 전국 118개 공단 중 시화반월, 전주, 대전, 대구, 청주, 울산, 구미, 여천공단 등 8개 주요 산단 지역을 program 개발을 위한 비교 대상 지역으로 선정하였고 이들 공단에서 사용되고 있는 약 1700여종의 화학물질의 물리 화학적 특성 자료와 생태 독성값의 문헌치, 추정치를 포함한 database를 구축하였다. 구축된 database를 활용하여 산단별, 화학물질별 생태 위해도를 상대적으로 비교한 결과 어류 만성의 위해도는 청주 공단>울산미포>여천 공단의 순이었고, 물벼룩 만성의 위해도는 시화반월>여천>울산미포 공단의 순이었다. 또한 산단별로 위해도 우선순위 물질을 선정하였으며 styrene, xylene 등의 위해도가 높게 나타났다. 이때 화학 물질의 수계 배출량은 TRI 자료와 사용량과의 상관관계로부터 구한 배출 계수를 적용하여 산정하였으며, 선정된 위해도 우선 순위 물질을 대상으로 실제 공단의 하천 시료를 채취, 분석하여 이 모형에 의해 예측된 생태 위해도의 타당성을 검증하고 보완하는 연구를 지속적으로 수행하여 예측 program의 신뢰도를 높이고자 한다.

  • The purpose of this study is to decide the suitability of the land use on eco-city by analysing ecological elements using GIS. Selected ecological elements for suitability analysis were altitude, slope, watershed, biotope, soil productivity, visual sensitivity, vegetation, and green connection. The category of each element was classified into 5 grades, and was given weight according to each element. The maximum value of each element was extracted from overlay analysis process. The result of analysis was classified into 5 grade finally. As a result, land use was proposed to be development, conservation, and preservation area.

  • 주택건설과 대규모 개발사업으로 인해 골재부족이 심화되면서 하천정비공사에서 골재채취가 주요한 사업이 되고 있다. 하지만 무분별한 골재채취는 하천생태계를 파괴시키는 원인이 된다. 본 연구는 하천에서 골재를 채취할 때 수생태계에 미치는 영향과 골재채취를 중지하고 휴식년제를 취할 때의 수생태계에 미치는 영향을 서로 비교${\cdot}$분석함으로서 하천골재 채취가 환경에 미치는 영향을 분석하였다. 연구방법은 수리학적 분석, 수질분석, 생태학적 분석을 이용하였다. 연구대상지역은 영산강의 일부구간으로 현재 이 구간은 골재채취공사가 진행중인 지역이다. 하상변동을 수치해석으로 모의한 결과 하상은 골재채취후 안정적으로 유지될 것으로 분석되었으며 골재채취가 수질에 미치는 영향은 그리 크지 않았고 단지 부유사(SS)가 약간 증가하였다. 생태학적 조사 결과 어류, 포유류, 양서류, 파충류와 조류는 공사로 인한 영향을 많이 받고 있는 것으로 분석되었다. 본 연구의 결과는 골재채취 사업에 따른 환경영향평가 및 사전환경성 검토에 활용될 수 있고, 하천공사와 수공구조물의 설계 및 유지관리 등에도 활용될 수 있을 것이다.

  • 해양에 적조가 발생하면 해수의 산소결핍 현상을 유발하고 동식물의 성장과 생존에 필수적인 태양광을 차단하여 해양 동물뿐 아니라 식물에게까지 치명적 피해를 준다. 또한, 대형 선박의 안정수(ballast water) 유입시 안정수 내에 포함되어 그들의 생활공간을 이동하면서 선박으로부터 다시 유출될 때 신생활공간에 외래 생물체로 침입하여 그곳의 기존 생태계를 파괴시키거나 교란하는 외래침입생물체는 해양생태계 환경파괴의 주범이다. 따라서 이들 두 종류의 해양생물은 부분적으로 상관성을 지니는 해양수산업계의 천적이며, 해양생태환경 파괴의 원인 제공자로써 마땅히 과학적 방법으로 제거되거나 방지되어야 한다. 이 논문은 해양수산업 계에 막대한 피해를 끼치며 해양생태환경 파괴의 주범으로 등장한 적조생물과 외래침입생물체들이 해수로부터 제조한 플라즈마 반응생성물에 처리된 결과를 분석하여 그 응용성을 조사하였다.
