  • 연안습지에서는 생태적으로 많은 생산물이 만들어진다고 평가되어 왔다. 이런 점들을 이용하여 연안습지를 연안환경관리에 적용하면 수질정화 등 다양한 효과를 볼 수 있다. 생태계 기능중 에너지흐름과 유기물, 영양염류가 연안습지의 수질정화에 중요하게 관계된다. 연안습지는 수생식물이 식재된 공간을 거치면서 처리되고, 토사나 오염물질의 유입을 방지하기 위한 공간의 조성과 바닥에서 영양염의 흡수 및 식물플랑크톤을 억제하는 방법이 적용될 수 있다.

  • 한국은 삼면이 바다로 되어 있어 염습지와 이에 인접한 해안사구가 발달되어 있다. 본 연구는 한국 서·남해안의 염습지와 사구에서 나타나는 염생식물의 군집과 식물상의 특성을 48개 지소의 571 식분에서 조사하고, 분석하여 연안 생태계의 특성을 밝히고자 시도하였다. 그 결과, 염습지에 분포하는 식물군락은 39개이었으며, 갈대군락의 분포면적이 가장 넓었고, 버들명아주군락이 가장 좁았다. 나문재군락이 해안선으로부터 가장 근접하여 분포하였고, 해홍나물군락이 해양쪽으로 가장 멀리까지 분포하였다. 해안사구에 분포하는 식물군락은 29개이었으며, 갯그령군락의 분포면적이 가장 넓었고, 수송나물군락이 가장 좁았고, 갯메꽃군락이 해안선으로부터 가장 근접하여 분포하였고, 해당화군락이 내륙쪽으로 가장 멀리까지 분포하였다. 염습지의 식물상은 6과 14속 17종 1변종 18분류군 이였으며(식물구계학적 점수; 16점), 해안사구는 11과 18속 20종 1변종 21분류군(식물구계학적 점수; 34점)으로 해안사구가 염습지 보다 약간 높게 나타났다. 이러한 결과는 한국 서남해의 연안에서는 해안사구가 염습지보다 해수의 영향을 간접적으로 받기 때문에 염도에 약한 식물도 생육할 수 있기 때문으로 해석된다.

  • Background: Organic carbon stored in coastal wetlands, which comprises the major part of oceanic "blue carbon," is a subject of growing interest and concern. In this study, organic carbon storage in coastal wetlands and its economic value were estimated using the raw data of 25 studies related to soil carbon storage. Data were collected from three tidal flats (one protected and two developed areas) and two estuarine salt marshes (one protected and one restored area). Bulk density, soil organic matter content, and standing biomass of vegetation were all considered, with Monte Carlo simulation applied to estimate the uncertainty. Results: Mean carbon storage in two salt marshes ranged between 14.6 and $25.5kg\;C\;m^{-2}$. Mean carbon storage in tidal flats ranged from 18.2 to $28.6kg\;C\;m^{-2}$, with variability possibly related to soil texture. The economic value of stored carbon was estimated by comparison with the price of carbon in the emission trading market. The value of US $ $6600\;ha^{-1}$ is ~ 45% of previously estimated ecosystem services from fishery production and water purification functions in coastal areas. Conclusions: Although our study sites do not cover all types of large marine ecosystem, this study highlights the substantial contribution of coastal wetlands as carbon sinks and the importance of conserving these habitats to maximize their ecosystem services.

  • Three brackish-water harpacticoid species belonging to the family Cletodidae are reported from the salt marshes in South Korea: Limnocletodes behningi Borutzky, 1926, L. angustodes Shen and Tai, 1963 and Kollerua longum (Shen and Tai 1979). Two genera, Limnocletodes and Kollerua, and the three species are newly added to Korean fauna. This paper deals with the redescription and systematic accounts of them, with detailed illustrations.

  • 본 연구는 2006년 7월부터 2008년 4월까지 한국 서남해안의 대표적인 18개 해안 염습지에서 생육지와 토양특성을 조사하여 서남해안 염습지 식생복원을 위한 기초자료를 제시하였다. 조사지역은 염습지의 생육지 유형에 따라 1차적으로 해안성 염습지와 하구성 염습지로 구분하고, 2차적으로 해안성 염습지는 점토성 염습지, 사질성 염습지, 사구성 염습지, 하구성 염습지는 염소택지와 기수성 염습지로 구분하였다. 생육지 유형별 주요 식물군락은 점토성 염습지에서는 갈대군락, 천일사초군락, 칠면초군락, 사질성 염습지에서는 갈대군락, 갯잔디군락, 천일사초군락, 퉁퉁마디군락, 큰비쑥군락, 해홍나물군락, 사구성 염습지에서는 갯그령군락, 통보리사초군락, 순비기나무군락, 염소택지에서는 갈대군락, 갯잔디군락, 해홍나물군락, 천일사초군락, 하구 염습지에서는 칠면초군락, 갈대군락, 천일사초군락, 나문재군락으로 나타났다. 염생식물 군락분포지역의 토양 환경은 염생식물의 생육지 특성에 따른 염생식물군락과 토양의 차이가 나타났다. 따라서 해안 염습지를 복원할 경우, 염습지를 대상으로 생육지 토양의 물리적 특성, 이화학적특성을 파악하여 생육지 조건에 맞는 염생식물을 선정하고, 이식한 후 자연식생이 형성된 지역을 중심으로 점차 확장시킴으로써 염생식물이 안정적으로 정착, 발아, 생장하는데 유리할 것이다.

  • Occurrence and distribution of the celluar slime molds in relation to the coastal plant communities of svven islands near inch'on wereinvestigated. as a results, total seven species were isolated from the soils of the coastal plant communities. These are dictyostelium mucoroides, polysphodylium pallidum, dictystelium polycephalum. d. mucoroides was the most commonly found in the coastal plant communities investigated, and was dominant pecularly in the coastal mixed forests, the coastal broad-leaved forests and salt marshes. In the coastal coniferous forest and the coastal dune sand plants, hoeever, p. violaceum was the dominant species. species diversity was relatively was relatively high in the coastal coniferous ferests and the coastal mixed forests. However, agerage number of species isolated from all plant communities was very low,2.8.

  • The coastal waters and the adjacent coastal lands strongly influenced by each other and includes islands, transitional and intertidal ares, salt marshes wetlands and beaches. We focus on the coastal zone because of its unique geographical characteristics, Its ecological and economic importance, and the increasing pressures on its integrity. Our coastal zone have been controlled individually about 50 of a different kind of laws, as a result, to reach an individual purpose of the laws, people have developed the coastal zone without considering environmental condition, which brought about ecological destruction, pollution and devastation of the coastal areas. Finally, In 1999, the Coastal Management Act and the Wetlands Conservation Act were established and hereafter the environmental concern has been increased. They will be an important role to preserve our environment of coastal zone. Here I will examine the Laws concerned with environmental management of coastal zone and indicate immanent problems of it. So, I expect that problems will be improved one by one through this paper.

  • A study on vegetation in the Mangyeong River and Dongjin River basins and the surrounding regions of the Saemangeum Reclaimed Land was conducted in a series of efforts to determine the expected ecological changes in the salt marshes, to restore their vegetation, to explore the restoring force of halophyte, to examine the community mechanism and, ultimately, to rehabilitate marshy land vegetation along the lakeside, coastal dune and salt marshes of the Saemangeum Project Area. The findings of the study may be summed up as follows: Five species such as Suaeda japonica, Salicornia herbacea, Atriplex gmelini, Aster tripolium and Suaeda asparagoides that are mostly distributed in the estuary of the Saemangeum Reclaimed Land were analyzed to examine the mechanism of halophyte to maintain their community. To find out the strategies of plants for survival and the cause of forming community structure, a research was made as for appearance ratio of young sapling. From the results of laboratory analysis into dynamics of the saplings of halophyte, it was revealed that the germination ratio of the dry area and submerged area decreases in the order of Suaeda asparagoides, Suaeda japonica, Salicornia herbacea, Atriplex gmelini and Aster tripolium.

  • To test whether the Grime's model on relationship between maximum standing crop plus litter (350~750g/$m^2$) and species density (10~30/0.25$m^2$) fit well or not, a total of 52 samples, with 4 replicate plots (0.5m$\times$0.5m each) per sample, was collected from various forests, grass lands and coastal salt marshes in midwestern part of central Korean peninsula from September to October in 1982. The result agrees well with the model for grass lands salt marshes, that is, shape of curve for the maximum standing crop (minus litter) against species density indicates normal distribution. The number of species was 11 for the grassland and 7 for the salt marshes within the range of 300g to 700g per square meter for the maximum standing crop. In forest stands, however, as the maximum standing crop of herbs increased the species density decreased. The Grime's model does not seem to fit with the resutls on forest stands of this study. It is examined further the relationships among the maximum standing crop, species density and eleven soil properties, and the possible cause of this discrepancy was disscused.

  • To describe the major environmental factors operating in coastal wetland and to characterize the distribution of the plant species over the wetland in relation to the major environmental gradients, 12 soil physical and chemical properties were determined. The gradient of water and osmotic potential of soil, electrical conductivity, sodium and chloride content and soil texture alsong the three habitat types of salt marshes, salt swamp and sand dune were occurred. The 24 coastal plant communities from principal component analysis (PCA) on the 12 variables were at designated as a gradient for soil texture and water potential related with salinity by Axis I and as a gradient for soil moisture and total nitrogen gradient by Axis II On Axis I were divided into 3 groups (1) 9 salt marsh communities including Salicornia herbacea communities (2) 5 salt swamp communities including Scirpus fluviatilis communities and (3) 10 sand dune communities including Jmperata cylindrica communities on Axis II were divided into 2 groups (1) salt marsh and sand dune communities, and (2) 3 salt swamp communities. The results could account for the zonation of plant communities on coastal wetland observed alsong envionmental gradients.
