Vegetation is the basis for biodiversity conservation and sustainable development. In the Environmental Impact Assessment (EIA), which is the most direct and efficient policy measure to prevent degradation of nature, vegetation-related assessment has limitations as it is not based on quantitative and scientific methods. In addition, it focuses on the presence of protected species; hence, it does not take into account the role of vegetation as a habitat on a wide-area scale. As a way to overcome these limitations, this study aims to contribute to the quantification and advancement of future EIA on vegetation. Through the review of previous studies, core areas, connectivity, and vegetation condition were derived as the items to be dealt within the macroscopic aspect of vegetation impact assessment. Each item was spatially constructed using land cover maps and satellite imageries, and time series change analysis was performed. As a result, it was found that vegetation has been continuously deteriorating due to development in all aspects, and in particular, development adversely affects not only the inside of the project site but also the surrounding area. Although this study suggested the direction for improvement of the EIA in the vegetation sector based on data analysis, a more specific methodology needs to be established in order to apply it to the actual EIA process. By actively utilizing various environmental spatial data, the impact of the development on the natural ecosystem can be minimized.

고수동굴은 1976년 9월 2일자로 우리나라 천연기념물 제 255호로 지정 받았으며, 학교법인 유신학운 박창원 이사장에 의하여 관광동굴로 개발되어 일반인에게 공개되기 시작했다. 이 동굴의 환경 변화는 동굴이 생성되면서부터 시작되는 것으로 자연적인 동굴의 성장과정에서 겪어야 하는 자연환경이 변화 때문에 동굴의 형성되기 시작한 초부터 변화되고 생태도 달라지기 때문에 동굴환경 이 파괴되기도 하고 변화하기도 한다. 그러나 근본적인 환경 변화는 동굴이 개발되어 공개된 이후부터 급격하게 일어나게 되는데, 특히 동굴의 파괴와 훼손현상은 동굴의 생태 변화를 촉진시키게 되는 것이다.(중략)

Nature-friendly river project has became common practice in Japan. In order to make it available for the conservation and rehabilitation of desirable water environment, water criteria for water environmental assessment must be established. Especially, the criteria estimating the effects on ecosystem in and around river should be constructed. In this paper, classification method for water quality has been developed using biological indices and applied to observed data in Honmyo River, Nagasaki, Japan. Modified PI method (BI') has been suggested and those of three most abundant species resulted effective estimate for an overall water quality with comparatively simple procedure. Extensive database management code was prepared for the comprehensive ecological monitoring of river basin, which includes various biota. That system enables easy access of all the ecological data for a dissemination of a sound and sustainable water environment. The result of this study could improve knowledge base, serve making consensus for citizens, and help river management plans. In Japan, citizen's realization and action are the most critical factor for nature-friendly river restoration project.

The criteria which have been used for the assessment of wildlife conservation values and particularly botanical values during the last decade, 1969~1986, were reviewed in order to select an appropriate set of criteria applicable for Korea. Fifteen studies, including studies of particular sites reviews of ecological evaluation are reviewed. Four criteria, rarity, diversity, size & extent and naturalness were used in more than half of these studies reviewed. The sixteen components were arranged with the scale of the sites, in view of the Korean situation. The human Interference, ecological fragility. as well as rarity, etc. were major components to be considered at small scale sites. In the contrary, area, diversity position in ecological and geographical unit, and naturalness, etc. considered the major components at larger scale sites. The components such as uniqueness, typicalness, research and educational, etc. were considered both applicable. Although this criteria should be tested by applications in the field and amended there after, It will be one of the first-step to evaluate of the protected areas, as well as specific plant species in the future.

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.

하천에서의 친수활동은 하천의 경관, 생태계, 물 등을 이용하여 이루어지는 인간활동과 심리적 만족감으로 하천어메니티의 한 요소로서 매우 중요하다. 그중 도시하천은 이용에 대한 요구와 자연환경보전이란 관심이 고조되고 있어 본 연구에서는 설문지 조사를 통한 전문가 의견을 토대로 다기준의사결정 기법을 이용하여 하천이용지수를 개발하였다.

Integration system of conservation ecology, ecosystem management and land planing in landscape scale is major principle strategy for national management system of environmental resource and biodiversity. Current conservation strategy is concerned with not only population and habitat level but also ecosystem and landscape level. In especially, ecological networking to link core areas or major habitat patches is most eminent and emerging issue in European Union (EU) and North America. Moreover, the promotion of national ecological network system in EU is focused on national cooperation to construct ecological corridor for key habitat that distributed in many countries. Integrating landscape ecology into conservation ecology and restoration have important role to stimulate the network system in regional and national level. In this review paper, comprehensive and necessary considerations arisen from the view of landscape ecology were discussed for the present situations of wildlife conservation and management in Korea compared with other countries. Especially, the conservation strategy and policy of biodiversity were addressed in broad sense including habitat protection, legal approaches, and ecological network programs. Finally, a national ecological network system was suggested for environmental policy in Korea in global consideration after the Korean Unification.

우리 남한지역에는 약 1,000여 개의 석회동굴이 있다. 이들 석회동굴들은 그 모두가 한반도 육지부에 있다. 물론 북한지역에 있는 석회동굴도 무려 1,000여 개가 추정된다고 하니까 남북한 모두 합친다면 2,000여 개의 석회동굴이 분포되고 있는 셈이다. 본 연구는 이들 석회동굴들의 형성과 발달이 어떠한 환경에서 이루어지고 있으며 이들이 자연 또는 인간의 개발이용에 의하여 어떻게 환경이 변하고 있으며 나아가서는 이들 동굴들이 환경보전을 어떻게 하여야 하겠느냐에 대한 소견을 피력하고자 하는 바이다.(중략)
