준설, 매립 등의 해상공사가 해양환경에 영향을 미치는 주 요인은 공사중 발생하는 부유토사이다. 이러한 부유토사는 주변 해역으로 확산되어 여러 방식으로 해양생태계에 피해를 유발할 수 있으며, 발생 가능한 피해의 범위와 정도는 부유토사 발생율과 해저 죄적물 입도분포 및 주변 유속에 따라 결정된다. (중략)

우리나라의 연안역은 지금까지 선진국으로의 도약을 위한 경제개발 수행과정에서 임해공업단지 및 발전소 건설, 간척 ·매립사업의 추진 등 연안해역에서의 사회, 경제적 활동의 증가에 따른 해양오염과 생태계 파괴가 가중되고 있다. 이러한 문제를 해결하기 위해서 일반적으로 현장관측, 수리실험, 컴퓨터를 이용한 수치모델이 이용되고 있는데 경제적인 이유와 편리함 때문에 국내에서는 주로 수치모델에 의존하고있다. (중략)

21C 현대 문명사회에서는 도시의 고밀도 및 팽창으로 인하여 도시 내 생태계가 파괴되면서 생물서식처의 환경 악화 및 엄청난 감소가 초래되었으며, 그 결과로 인하여 인간과 생물이 접촉할 수 있는 공간이 현저하게 줄어들고 있다. 또한 도시 영역의 확장을 위하여 산림 및 녹지의 감소, 녹지의 분절 및 단절화, 해안 매립 등이 계획 없이 무분별하게 진행됨으로써, 각종 동식물의 개체 수 감소 및 토양의 건조화 등이 발생하고 있으며, 그 영향으로 생물종의 다양성이 떨어지고, 도시 생태계의 교란이 심해지고 있다. 이러한 도시 생태계의 교란은 도시에 거주하고 있는 시민들의 생활의 질이 떨어지게 하고 많은 환경 문제들의 주원인이 되고 있다. 지속적이면서도 자연친화적인 도시발전을 위해서는 도시 내 자연생태계를 회복하고 생물서식공간을 종합적으로 보전하면서 복원해야 한다는 요구가 높아지고 있지만, 이를 체계적으로 이루기 위한 방법론의 부재에 시달리고 있었다. 이러한 가운데 유럽을 중심으로 생겨난 비오톱(Biotope)과 비오톱 지도화 방법이 생태계를 보전하며, 시민들에게 다양한 자연체험과 휴양 기회를 제공하고 친환경적인 도시계획을 위한 핵심적인 역할을 하는 것으로 인식되고 있다. 하지만, 기존의 비오톱 지도는 이미지 기반의 2차원 지도로 제공되고 있어, 거리 및 공간 분석에 취약하고 정보전달력이 부족하여, 익숙한 전문가가 아닌 경우 비오톱을 이해하는데 상당한 정도의 시간이 필요하였다. 이에 본 논문에서는 공간정보가 결여된 2차원 형태의 GIS 데이터를 기반으로 3차원 공간 데이터를 자동으로 생성하고, 위성영상과 DEM(Digital Elevation Model)을 이용하여 3차원 지형을 만들어 각 주제도별로 입체적인 분석이 가능하도록 하였다. 또한 동영상 녹화 기능과 3차원 객체 추가 기능을 이용하여, 자연생태계를 고려한 도시의 설계를 진행하는 경우 3차원적인 모델링을 제공함으로써 효과적이면서도 사용자의 이해도를 향상 시킬 수 있는 정보 전달력을 가질 수 있도록 설계 및 구현하였다.

The coastal area is the place where two conflicting values provide opportunities for recreation, tourism and conservation of the natural environment. Most of these coastal areas have been disregarded in terms of tourism because of the high value placed on natural resources. Management strategy has usually been first on the priority list of natural. resources. However, due to the significant number of visitors, the Important-Satisfaction Analysis(ISA) was applied as a mean of complement since the 1970s. This study analyzed the difference between visitor satisfaction and the importance of the main management strategy targeting visitors to Sun-cheon Bay Ecological Park on weekdays and weekends. Results show that Sun-cheon Bay Ecological Park and the city government have paid a lot of attention and invested a lot of money, but efficiency of publicity didn't come up to their afford. Therefore, we should prepare information facilities, public education facilities and human power. Also needed are visitors' temporal-spacial control to set specific programs and a guide for information education control. It means visitors' company forms change depends on weekday and weekend. In addition, a breeding space for birds should be built for observation, education and exhibition to help meet visitor expectations. Visitors' positive satisfaction might be provided in establishing strategy as a very important measure in limited area. In conclusion, this study might be provided as preliminary data when the management strategy and related guidelines are established through the management priority of coastal regions where importance and satisfaction conflict.

Tidal flat, classified as wetland of coastal zone, is critical transitional zone connecting sea with land, and fulfills a variety of functions necessary for maintaining coastal ecosystem. Although it is critical to protect and strengthen its functions of coastal wetlands, tidal flat has been mainly viewed as areas for development in Korea. Therefore, this study provides with the effective mitigation measures so as to minimize adverse impacts of tidal flat reclamation projects on the proper environmental values. So far, coastal development has not considered as important the fact that development site consists of tidal flat in site selection. Therefore, large scale of tidal flats was abused. Problems were emerged only after tidal flat development was already planned. The original plan had to be revised. To rectify the problem, impacts of development on the environment need to be discussed based on the initial development planning. Particularly, sandy beaches, rocky shores and shallow areas, underwater forest including seagrass beds as well as the tidal flat in good condition should be excluded from development site.

The wetland ecosystem has a key role in climate change and can capture and store carbon long-term as blue carbon. Currently, the Republic of Korea and People's Republic of China are preparing for the UNESCO World Natural Heritage Phase II inscription, and cross-border cooperation among the two Koreas and the People's Republic of China is expected in term of the coastal wetland in the Yellow Sea region. However, there is a lack of research on the importance of coastal wetland in the Yellow Sea region for migratory bird habitats, roosting sites, feeding grounds, and stop-over sites. Thus, this study focused on the coastal wetland of the Yellow Sea region, including the southwestern coastal wetlands in the Republic of Korea, the Yancheng National Nature Reserve in the People's Republic of China designated as UNESCO World Natural Heritage, and the Mundok Migratory Bird Reserve in the Democratic People's Republic of Korea, which is listed on the Tentative List. The cooperation for ecosystem conservation between the two Koreas and China was analyzed. The importance of coastal wetlands in the Yellow Sea region as habitats for migratory birds, roosting sites, feeding grounds, and stop-over sites, significant characteristics of Yellow Sea coastal wetlands, and conditions for cooperation among three countries, were analyzed. The direction of ecosystem conservation cooperation for coastal wetlands in the Yellow Sea region in this study will be developed into Pan-Yellow Sea conservation.

Korea is surrounded by the sea on three sides, salt marshes and coastal sand dunes adjacent to them are developed. This study attempted to reveal the characteristics of the coastal ecosystem by investigating and analyzing the characteristics of plant communities and flora of 571stands of 48 sites in the salt marshes and coastal sand dunes on the western and southern coasts of Korea. As a result, in the salt marshes, 39 vegetation units appeared, with Phragmites australis community having the widest area and Chenopodium virgatum community having the narrowest area. Suaeda glauca community was distributed closest to the coastline, while Suaeda maritima community extended the farthest seaward. In the coastal sand dunes, 29 vegetation units were distributed with Elymus mollis community having the widest area and Salsola komarovii community having the narrowest area. Calystegia soldanella community was showed closest to the coastline, while Rosa rugosa community extended the farthest landward. The flora of the salt marshes consisted of 6 families, 14 genera, 17 species, 1 variant, and 18 taxa (floristic regional indicator score; 16) and the coastal sand dunes consisted of 11 families, 18 genera, 20 species, 1 variant, and 21 taxa (floristic regional indicator score; 34) appeared slightly higher than that of salt marshes. This result is interpreted that halophyte that are sensitive to salinity can grow on the coast of the west-south coast of Korea because coastal sand dunes are more indirectly affected by sea than salt marshes.

In this study we predicted some of the negative effects on the ocean ecosystem and water quality, caused by a coastal reclamation project in semi-closed bay that makes it extremely difficult to be purified by natural process. In order to predict change of water quality triggered by coastal reclamation, the 3D hydrodynamic model and material cycle model are used. And we suggested new ecological park, an artificial beach and eco-friendly revetments on the reclamation area to mitigate the environmental impacts affecting this area using the numerical simulation results and observation data.

The Taeanhaean National Park is located on the middle of the west coast of Korean peninsula. Due to the relatively high wave energy, large tidal range which is about 7m, and extremely complex coastal line, various coastal land-forms such as mud-flats, sand beaches, sand dunes, sea cliffs etc. are well distributed in this area, and thus various coastal ecosystems are well preserved. However, because of reckless sand diggings and construction of artificial structures in the coastal zone, the natural flowing and exchange of coastal deposits were disturbed and the erosion in the beach and the dune has been seriously accelerated. To understand of the causes of these problems, we tried three times periodical measuring with VRS/RTK GPS instrument at the Hakampo and Anmyeon beach. According to seasonal changes of the coast-line, beach area and cross-section of study sites, generally erosion process was dominated in the summer and deposition process was followed after summer.
