This study examined ecological grade of tidal flats at 59 sites along the west and east coast of Korea from January 1998 to December 2002. Assessment of ecological grade based on 7 headings includes biological and human geographical factors, such as species diversity and richness, utility value of species, possibility of damage and reservation conditions of coastline. Total of 181 species with 37 families of 14 orders were listed in this study. The highest scores (ecological grade I) showed at these five sites, Hagampo in Chungnam, Ui-do and Geomun-do in Jeonnam, Bijin-do and Maemul-do in Gyungnam. Half of thestudy sites belong to ecological grade II and 19 sites showed ecological grade III. Singyeong in Gyeonggi, Janghang in Chungnam, Gyehwado and Gomso in Jeonbuk, Dadepo in Busan were assessed as ecological grade IV. Grade V (the worst) was not found in this study.

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.

The purpose of this study was to explore the ecological aesthetic features and the implications for ecological landscape design by analyzing the design philosophy and ecological artworks of Patricia Johanson, an ecological artist. Literature review and a field visit were conducted to investigate Johanson's four art projects that express the functional purpose, artistry, and locality of symbiosis with nature and restoration of ecosystem habitats. As the results of analysis, first, Johanson's work created 'functional art work' and 'artistic infrastructure'. Second, the historical and regional characteristics were expressed artistically and symbolically. Third, Johanson is characterized by connecting humans and nature through the publicity of works of art, and raising the awareness of preservation of nature and environment among the community and children. Johanson's innovative works can provide inspiration for landscape architects pursuing functional and sustainable landscape design.

The Impact Mitigation Regulation was first introduced in Germany with an intention to avoid or reduce the natural ecology and landscape infringement as much as possible according to the development project. The system has is an advantage of being able to efficiently operate the linkage policy of land planning and environment planning to prevent the excessive development of the national land and to continue to manage it. This study applied the German natural impact mitigation system by revising and supplementing it according to the domestic situation with a biotope map of Juam-dong, Gwacheon City, as a case study area. Spatial analysis was conducted of biotope maps, landscape maps, and NDVI maps to suggest a plan to derive and preserve the areas excellent in an ecological and environmental value. It was confirmed the Impact Mitigation Regulation could be used as a policy link of the land-environment policy that minimizes the degree of the damage that cannot help occurring necessarily in the development of the national land and to manage that damage from the planning stage.

The Ecosystem and Nature Map (ENM) is basic map for current status of natural resources. The map has been offered information to ecological conservation and restoration, as well as to land use planning and policy making. The map composed of 794 sheets in 1:25,000 scale classifies total areas into three grade zones (1st, 2nd and 3rd grade zones) and separately managed zone. In 2005, the first draft Ecosystem and Nature Map was prepared by the second National Ecosystem Survey. It was opened for the people to search and appeal. So 1,419 cases of public appeals on the first draft Ecosystem and Nature Map were submitted in 2005. After partial revision, the first Ecosystem and Nature Map was announced in 2007. The second draft Ecosystem and Nature Map was prepared by the third National Ecosystem Survey and opened to public in 2012. As a result, 1,263 cases of public appeals were submitted in 2012. Since the first announcement of the Ecosystem and Nature Map in April 2007, 182 cases of public appeals on the Map were submitted until December 2013. Among them, 159 cases were announced with revision. According to the first Ecosystem and Nature Map announced in 2007, graded areas covered 7.5% in the 1st grade zone, 39.2% in the 2nd grade zone and 44.7% in the 3rd grade zone of the national land area, respectively. In the second draft Ecosystem and Nature Map in 2012, areas of the 1st grade zone and the 2nd grade zone were 9.2% increased 1.7 percentage points and 45.5% increased 6.3 percentage points, and areas of the 3rd grade zone were 36.6% decreased 8.1 percentage points. Among areas of the 1st grade zone, Gangwondo occupies 54.3% in 2007 and 47.6% in 2012. Gangwondo consists of the highest percentage of the 1st grade zone and the smallest of the 3rd grade zone. Seoul has the highest percentage of the 3rd grade zone. There were the highest increase of the 1st grade zone in Gyeongsangbukdo and the highest decrease in Jeollabukdo and Seoul. Vegetation is the most important evaluation factor to determine the grade of the Ecosystem and Nature Map.

To investigate the structure and the conservation strategy of Nature Ecosystem Preservation Area, 65 plots(10m$\times$10m) set up with random sampling method were surveyed. five group -Larix leptolepis Community, Quercus mongolica-Fraxinus rhynchophylla Community, Fraxinus rhynchophylla-Quercus mongolica community. Quercus mongolica-Acer pseudo-sieboldianum community, Quercus mongolica community were classified by cluster analysis. High positive correlations was proved between Quercus mongolica and Sorbus of alnifolia, Acer Mono, Lonicera praeflorens, Sorbus commixta ; Acer mono and Lonicera praeflorens, Sorbus commixta ; Maackia amurensis and Acer triflorum ; Fraxinus rhynchophylla and Betula davurica ; Lonicera praeflorens and Cornus controversa, Sorbus commixta ; Acer triflorum and Rhamnus toshinoi ; Pyrus ussuriensis and Prunus padus ; Cornuscontroversa, and Sorbus commixta, and high negative corrlations was proved between Quercus mongolica and Larix leptolepis, Carpinus cordata ; Tilia amurensis and Larix leptolepis, Morus bombycis. Species diversity(H' ) of investigated groups were ranged 0.4443~1.2036.

For the zoning of natural ecosystem, Vegetation Index is calculated from the vegetation data surveyed on Baekdudaegan (Pijae-Doraegijae). Five factors -biodiversity, conservation value of the stand, environmental quality, longevity of the stand, site productivity- are considered in the calculation of Vegetation Index. Vegetation Index might be a useful zoning tool for management of Baekdudaegan. For Vegetation Index I, 59 sample plots 52.2% of total 113 sample plots are belong to core area, 34 sample plots 30.l% and 20 sample plots 17.7% are belong to buffer zone and transition area, respectively. For Vegetation Index II, 49 sample plots 43.4% of total 113 sample plots are belong to core area, 38 sample plots 33.6% and 26 sample plots 23.0％ are belong to buffer zone and transition area, respectively.

종래의 개발은 양면성을 가지고 있다. 하나는 개발로 인한 경제적 효율성과 편리성 부분이고, 다른 하나는 그러한 개발로 인한 자연훼손 및 생태계 파괴이다. 이로 인해 개발과 보전은 양립할 수 없는 상반적인 개념으로 받아들여져 왔고, 개발론과 보전론의 대립적 구도가 지속되어 왔다. 우리나라는 국토의 65% 이상이 산지이기 때문에 산지의 부분적 개발은 피할 수 없는 사회적 요구인 동시에, 산지는 자연생태계의 보고로서 생태계 보전이 필수적인 지역이다. 이러한 산지 개발과 보전에 대한 상반적 이해를 통합하여 자연과 인간의 공생체계를 갖추기 위해서는 인간중심의 사고에서 탈피하여 사람과 생태계 그리고 자연을 하나로 보는 총체적인 측면에서 접근하는 새로운 패러다임이 설정되어야 한다. 본 연구에서는 산지의 정량적인 가치를 평가하기 위해 시 공간적으로 다양한 인자들에 대해 시스템적인 관점에서 그 중요성을 고려하고자 하는 에머지 개념을 통해 산지 본래의 가치를 평가하였다. 에머지 개념은 그 동안 생태계가치평가, 개발사업의 편익-비용평가, 환경수용력 평가, 개발대안 평가, 환경계정, 환경훼손 소송관련 비용 평가 등에 적용되었다. 이러한 에머지 개념을 이용한 평가 방법을 통한 의사결정이 이루어지면 산지뿐만이 아닌 생태계의 지속가능한 이용을 실현하기 위한 적절한 정책의 선택과 이의 이행 실효성을 높일 수 있을 것으로 기대되며, 자연환경 가치의 정량적 평가를 통해서 우리는 한층 더 자연환경 및 자원의 다원적 기능에 대한 자각을 할 수 있을 것으로 판단된다.
