Korean society has been recently promoting the restoration of coastal wetlands. These efforts might become the basis of a policy framework that compensates for the limitations of a regulation-oriented policy such as the designation of Marine Protected Areas (MPAs). The shift in government policy could contribute to strengthening the socioeconomic infrastructure of coastal development through the accumulation of ecological capital. Although our scientific efforts and social demands in regard to the ecological restoration of the coastal wetlands have increased during the past years, the bases for restoration in Korea requires that scientific, technological, financial, social and legal aspects be enhanced. The present study re-examined the concept and attitudes behind coastal wetland restoration in the light of changing circumstances in Korea. Herein, we first defined coastal wetland restoration as "An act of recovering the functions of the ecosystem of coastal wetlands to a state that resembles conditions prior to being damaged." Next, this study discussed the limitations and future directions of such restoration efforts based on the descriptive analyses of recent restoration practices from social, economic, and technological aspects. Finally, we suggest future policy directions regarding coastal wetland restoration on the basis of a PFST (Policy, Financial, Social, and Technological) analysis; 1) re-arranging legal mechanisms, 2) setting multi-dimensional restoration goals, 3) establishing a multi-discipline- and convergence based R&D system, 4) linking spatial management and local development to the restoration, 5) building restoration governance at the local level, 6) implementing an ecosystem service payment system, and 7) applying test-bed projects in accordance with proper directions.

The purpose of this study is to suggest the visual landscape plan for Shinan province with ecological landscape resources, which is comprised of more than 1,000 islands. The plan was done by the order of image plan, landscape structure plan and detained landscape plan. The image of Shinan province was elicited as 'nature', 'complexity' and 'connectivity', by the aspects of planning, cognitive and strategic sides. The landscape zones are planned, such as leisure zone, rural & marine ecological zone and marine tourism zone, and the landscape axes are also set, such as marine axis, ecological axis and circular axis. Especially to conserve the ecological resources, some conservation zones are proposed and design guidelines for each landscape type are also provided, which are not commonly included in the urban landscape plan. Consequently, the landscape plan and ecological environmental plan were complementary to each other. In the detailed landscape plan, more specific plans and design guidelines are suggested for coastal scenery, village and forest scenery, historical and cultural landscape management and promotion. To improve the visual landscape in terms of planning and administrative aspects, the visual landscape plan has become increasingly important for the local governments. The establishment of visual landscape plan may hopefully help to make Shinan province more beautiful and attractive. The landscape plan and ecological environment plan should be integrated, and the further discussion and research are necessary.

This study was surveyed from January to september, 2007 in order to evaluate the function of coastal wetland as a ecological axis in korea peninsula. Assessment was done by RAM (Rapid Assessment Method). RAM is consisted of total 8 contents and divided into high, moderate, low. The preservation grade of RAM is divided into 4 grades; absolute preservation, preservation, improvement and improvement or restoration. Throughout survey on total 14 wetlands of marine, estuary wetland and back marsh which are distributed in west coast in chung-nam province, their function was assessed. As result, total all the 14 wetlands were judged as preservation grade by assessment of 8 functional contents. The function of wetlands assessed as preservation grade showed high in water quality protection and improvement. Also, showed high in vegetation diversity, wildlife habitat and aesthetic recreation. Meanwhile, showed low in ground water recharge, Shoreline/Stream Bank Protection, Flood/Stormwater storage and Flood flow alteration. Of wetlands evaluated as preservation grade, Dae-ho, Sinduri, Bu-Nam lake, Sowhang dune and keum river estuary were assessed as absolute preservative area owing to habitation of international protection species and endangered species. These wetlands are essential to be managed continuously as a area having high ecological value. Farther, this wetlands will be done as a axis of ecological network related to land ecosystem.

This study aims to establish the national strategy for biodiversity conservation by analyzing the current status of ecodiversity as the foundation of biodiversity conservation. Furthermore, this study has another purpose of preparing the measures for conservation and restoration of biodiversity. Ecodiversity was discussed as the basis for conserving biodiversity. Five climate zones and 14 climatic regions, eight plant geographic regions, three massifs and major geologic series, horizontal and vertical topographic conditions, 16 ecoregions, major ecosystems including forest, river and streams, wetlands, coast and marine, agriculture, and urban esosystems, and land use types were discussed as the element of the ecodiversity. In terms of biodiversity conservation, the actual conditions of each ecological unit were reviewed and measures were proposed to reduce biodiversity loss. Destruction and fragmentation of habitat, poor ecosystem management due to socioeconomic changes, the effects of exotic species and chemicals, and climate change were discussed as the major factors causing biodiversity loss. Systematic monitoring based on scientific principles and ecological restoration based on those monitoring results were recommended as measures for biodiversity conservation.

Experimental design for ecological restoration approach was investigated from the P' company's slag dumping area with higher pH value. The degree of pH recovery was measured by the injection of carbon dioxide from the LNG exhaust gas, and the residual carbon, for example, calcium and carbonate which can be controlled by artificial seaweed beds. The degree of adaptability from 3 algaes (Undaria pinnatifida, Sargassum horneri and Ecklonia stolonifera) and uptake nutrient function of Ecklonia stolonifera chosen in the first treatment were measured in the laboratory to determine the transplanting algae in artificial seaweed beds. The higher value of pH was decreased to 7.0~8.5 by injection of LNG exhaust gas with flow rate $20\;m^3/min$. In the experiment design at laboratory, the upper part of frond of Undaria pinnatifida and Sargassum horneri began to decay, and the color changed after 10 days. However, those of Ecklonia stolonifera were after 14~20 days. The uptake rate of nutrient from Ecklonia stolonifera was higher than those of other algaes, and those was similar pattern in the control (e.g. seawater); The DIN concentration uptake of Ecklonia stolonifera was $1.88\;{\mu}g/L/hr$ avg. in leachate, but $2.19\;{\mu}g/L/hr$ avg. in seawater. However, the ${PO_4}^3$-P concentration uptake was $0.18\;{\mu}g/L/hr$ avg. in leachate, but $0.31\;{\mu}g/L/hr$ avg. in seawater. These result indicated Ecklonia stolonifera uptaked these nutrients in the leachate as well as in seawater, and it may suggested for this species to transplant for constructing artificial seaweed beds.

본 연구는 우리나라 제주 해역의 여름철 해조 군집 특성과 갯녹음 현황을 파악하고자 수행하였다. 연구는 2017년 7월부터 9월까지 스쿠버 다이빙(SCUBA Diving)을 이용하여 정량 조사 및 정성 조사를 시행하였다. 연구 결과 녹조류 11종(9.1 %), 갈조류 24종(19.8 %), 홍조류 86종(71.1 %) 등 총 121종의 해조류가 확인되었다. 지역별로는 형제섬이 60종으로 출현종수가 가장 많았으며, 하례가 18종으로 가장 적었다. 연구 지역의 평균 생물량은 $1,503.0g{\cdot}m^{-2}$이며, 주변 도서의 평균 생물량($3,268.7g{\cdot}m^{-2}$)이 본섬의 평균 생물량($914.7g{\cdot}m^{-2}$)보다 높았다. 우점종은 주변 도서에서 Sargassum macrocarpum, 본섬에서 Ecklonia cava로 나타나 생물량뿐만 아니라 종 조성에서도 차이를 보였다. 해조 군집 특성(종 조성, 생물량, 대형 갈조류의 생물량 비율), 무절산호말류의 피복도, 조식동물의 밀도 등을 토대로 연구 지역의 여름철 해조 군집 상태를 평가한 결과, 형제섬과 마라도 두 지역은 우수한 해조 군집을 유지하고 있는 것으로 판단되어 보전 및 지속적인 관리가 요구되며, 다른 6개 지역은 각 지역별로 해조 군집의 조성 내지 복원이 필요한 실정이다. 갯녹음 현상이 가속화됨에 따라 모니터링뿐만 아니라 현재 해조 군집의 현황 파악이 제대로 이루어지지 않은 지역을 대상으로 해양 생태계의 실태를 파악하는 일도 시급한 것으로 판단된다.

Sea level rise caused by climate change has become a global issue. Sea level rise seems to be an important factor of the research for coastal areas as it affects topography and vegetation of coasts and especially for the plan of coastal wetlands restoration which needs to be carried out for a long term, it has to be considered sufficiently. The coastal wetlands in Korea was damaged by the land reclamation project but recent concerns on the restoration have increased as its value is evaluated highly. Suncheon Bay had also reclaimed from wetlands to rice field once however this site is very active for restoration nowadays. This study estimated an effect according to sea level rise by 2100, reappearing the none dike condition of Suncheon Bay so that it can be taken account of a future plan of wetland restoration. The Sea Level Affecting Marshes Model(SLAMM) was selected as predicting model. The input data such as DEM(Digital Elevation Model), slope, wetlands category, sea level rise senario, tidal range and accretion rate was applied for the simulation. The results showed a decrease in tidal flat, an increase in sea area and a change of the rice field to transitional salt marsh consistently by 2100. These results of this study could be used as baseline data in the future plan of ecological restoration in Suncheon Bay.
