본 연구는 국내 하천에서 방치되고 있는 구하도 구간의 물리적 상태를 파악함으로써 이를 보전 또는 관리하기위한 기초자료로써 활용하고자 한다. 국내의 구하도 구간은 자연적인 발생보다는 하천의 직강화, 하천부지 이용의 고도화 등 인위적인 교란으로 인해 형성된 것이 대부분이다. 이와 같이 사행구간의 하도가 절단(Cutoff)됨으로써 형성된 구하도는 우각호 형상의 습지형 구하도와 이미 육역화되어 농경지나 나대지로 이용되는 육화형 구하도로 구분할 수 있다. 특히 폐천(Abandoned Channel)화가 진행된 대부분의 습지형 구하도는 수질, 생태계, 육역화, 농업용수 이용 등 다양한 문제점 및 현안을 가지고 있기 때문에 이에 대한 보전 또는 관리가 필요하다. 이를 위해서는 우선적으로 습지형 구하도의 현재를 진단하고 평가하기 위한 연구가 선행되어야 한다. 따라서 본 연구에서는 습지형 구하도를 평가하기 위한 평가지표를 제안하고 이를 만경강 습지형 구하도 5개소에 적용하였다. 평가지표는 국내외에서 제안된 하천환경 평가지표와 RAM(일반기능평가기법)을 토대로 작성하였다. 이 평가지표는 단절된 습지구간에 적정한 지표, 자료 획득의 용이성, 즉시 적용 가능한 것을 우선순위로 선정하였다. 평가지표는 자연도, 서식처, 친수, 수질 등 4개 지표를 세분화한 총 25개 항목으로 제안하였다. 만경강에 대한 물리적 평가결과 습지형 구하도의 경우 서식처, 자연도 부분이 높은 점수를 획득한 반면 수질과 친수 지표는 상대적으로 취약한 것으로 평가 되었다. 이와 같은 결과는 향후 만경강 습지형 구하도에 대한 보전 및 관리계획을 수립함에 있어 주요 고려사항이 될 수 있을 것이다.

The Ministry of Environment of the Republic of Korea set up 'the $2^{nd}$ Fundamental Plan for Wetlands Conservation' to facilitate systematic surveys and management of various national wetlands and to promote sustainable conservation and use of those wetlands. The mid-term fundamental plan was established in accordance with the Article 5 of the Wetland Conservation Act, which spans 5 years from 2013 to 2017 and covers national wetlands including inland wetlands and coastal wetlands stated in the Act. The fundamental plan aims to promote the wise use of wetlands through establishing policies for sustainable conservation based on the assessment of implementation of the $1^{st}$ Fundamental Plan, setting up a scientific framework for establishment and implementation of national wetland policies by improving wetland survey systems and enhancing basis wetland data, improving the ecological health of wetlands and securing biodiversity conservation of wetlands by strengthening conservation and management system of national wetlands, and through raising public awareness and diversify education and promotion tools. The main objectives of the $2^{nd}$ Fundamental Plan is to revise the entire Wetland Conservation Act, to create a new monitoring system of national inland wetlands, to upgrade the national wetlands inventory, to reflect the 'Ecological Map' for promoting precautionary management of wetlands, to improve the 'Wetland Restoration and Management' system to build wetlands resilience, and to systematize the wise use of wetlands that benefits local people. As the Ministry of Environment plans to establish its other master plan for wetland conservation based on the $2^{nd}$ Fundamental Plan, this document introduces the $2^{nd}$ Fundamental Plan to stakeholder and wetland professions.

기존의 댐에 대한 연구는 이 치수 및 전력생산, 환경문제와 같은 댐의 전통적인 기능과 그 파급효과에 대한 연구가 주로 진행되어 왔으나 댐의 친환경적 활용방안 및 댐에 서식하고 있는 동 식물 및 생태계에 대한 연구는 상당히 미흡한 실정이다. 특히, 댐 상류지역 및 주변지역에 위치하고 있는 습지는 댐의 수질개선, 희귀 동 식물의 서식처 확보 등과 같은 생태보존, 위락 경관 생태공원 등의 기능을 제공할 수 있다. 이로 인해 댐유역에 위치하고 있는 자연습지의 보전뿐만 아니라 훼손에 따른 대체습지(인공습지)의 필요성이 점증되고 있는 실정이다. 따라서 본 연구에서는 현재 운영되고 있는 댐을 대상으로 댐이 지니고 있는 습지의 역할을 검토하고자 수문지형학적 방법인 HGM 방법을 이용하여 댐습지의 기능을 평가하였다. HGM 방법을 이용하여 댐습지의 기능평가를 수행하기 위해서는 대상습지와 기준습지가 필요하며, 본 연구에서의 대상지역은 댐 유역내 습지지역이 조성되어 있는 보령댐으로 선정하였으며, 기준지역은 보전이 잘 되어 있고 람사르 협약에 등록된 우포늪으로 선정하였다. HGM 방법에서의 기능 평가는 수문학적, 생지화학적, 식물 서식처 그리고 동물 서식처 측면으로 구분하여 대상지역과 기준지역을 비교하는 방식으로 이루어진다. 그 결과, 댐습지가 지니고 있는 습지의 기능이 자연습지에 비해 평균적으로 약 50%정도의 역할을 하는 것으로 나타났다. 이는 댐습지가 습지로서의 역할을 기능적으로 100% 수행을 못하고 있지만, 댐이 습지의 기능을 어느 정도의 수준까지는 수행을 하고 있음을 알 수 있다.

The ecosystem and landscape conservation areas of Seoul were designated according to the Natural Environment Conservation Act and the Natural Environment Conservation Ordinance. With the adoption of the "Rapid Assessment of Wetland Ecosystem Service (RAWES)" approach and the "wetland ecosystem service" for the Ramsar Wetland City Accreditation at the 13th Meeting of the Conference of the Contracting Parties to the Ramsar Convention on Wetlands in 2018, the need for data evaluating wetland ecosystem services has become a necessity. Therefore, in this study, we selected five wetlands from the ecosystem and landscape conservation areas in Seoul, having high ecological conservation values, and evaluated their carbon sequestration and economic value assessment using the InVEST model, which is an ecosystem service evaluation technique. The evaluation results for carbon storage in each wetland are as follows: Tancheon Wetland: 3,674.62 Mg; Bamseom Island in the Hangang River: 1,511.57 Mg; Godeok-dong Wetland: 5,007.21 Mg; Amsa-dong Wetland: 7,108.47 Mg; and Yeouido Wetland: 290.27 Mg. Particularly, the Tancheon Wetland showed the lowest carbon sequestration of 1,130.37 Mg, as compared to the results acquired in 2013, of 4,804.99 Mg. When the average effective carbon rate of $16.06 (US) was applied to the decreased carbon sequestration value, a loss of $15,910.58(US) was calculated. Furthermore, if the average social cost of carbon ($204 (US)) is considered, which includes the impact of climate change on productivity and ecosystems, the total loss is equivalent to $202,101.97 (US). This study aims to examine the natural resource value of urban wetlands by evaluating selected major wetlands in Seoul. This study can be utilized as basic data to plan for the protection and management of the ecosystem and landscape conservation areas. Additionally, because wetland value assessment is considered essential, the results of this study can be used in future research to provide measures for evaluating ecosystem services in the Ramsar Wetland City Certification System. Moreover, this study can be utilized for selecting important wetlands as Ramsar sites, and to raise awareness about the significance of conserving urban wetlands, and for expanding international exchange among the Ramsar Wetland sites.

최근 환경에 대한 관심이 증대하면서 생물다양성, 홍수조절, 온실가스 저감 등 다양한 기능을 수행하는 습지에 대한 보전 및 복원을 위한 많은 노력들이 진행되고 있다. 습지 보전 및 복원을 위한 다양한 방안 중 하나가 댐 및 주변지역을 습지로 조성하여 활용하는 방안이라고 할 수 있으며, 이를 위해서는 댐 및 주변지역의 습지로서의 활용을 위한 특성 파악이 우선적으로 이루어져야 한다. 따라서 본 연구에서는 댐 주변지역에 조성된 습지와 댐 저수지 자체를 모두 포함하여 댐습지라고 정의하고, 댐습지가 지니고 있는 습지의 기능 및 경제적 가치를 추정하고자 하였다. 본 연구의 대상지역은 기준습지와 대상습지로 구분되며, 기준습지는 우포늪과 보령댐, 대상습지는 용담댐이다. 댐습지의 기능평가는 수문지형학적 특성을 고려하는 HGM(Hydrogeomorphic Method)을 이용하였으며, 가치평가는 조건부가치측정법(CVM)을 이용하였다. 기능평가 결과는 우포늪과 보령댐을 각각 기준지역으로 선정하였을 경우로 구분하여 나타낼 수 있다. 자연습지인 우포늪을 기준지역으로 선정하였을 경우에는 댐의 주목적과 관련이 있는 수문학적 기능이 높게 평가되었으나 습지 내에서 진행되는 생지화학적 기능과 다양한 식물 종에 대한 서식처로써의 기능은 다소 미흡한 것으로 평가되었다. 보령댐을 기준지역을 선정하였을 경우에는 일부 기능을 제외하고 대부분의 기능이 유사한 것으로 평가되었다. 조건부가치측정법을 이용한 용담댐의 경제적 가치평가는 댐습지 생태공원조성에 따른 훼손된 습지의 보호, 희귀생물종의 보호, 휴양 및 여가기능 제공을 주요인으로 설정하고 설문조사를 수행하여 가치를 추정하였다. 그 결과 용담댐의 총 가치는 우포늪의 가치와 비교하였을 때 우포늪의 35~41%에 해당하는 것으로 추정되었다. 본 연구에서 수행된 댐습지의 기능 및 가치평가 결과는 댐이 단순히 이 치수 측면으로만 이용되는 것이 아니라 생태학적으로도 활용성이 있다는 사실을 나타내고 있다. 이를 통해서 향후 댐의 친환경적 활용 방안 및 댐습지 관리 방안에 중요한 기초자료로 활용될 수 있을 것으로 판단되며, 댐에 대한 긍정적인 인식 증진에도 많은 도움이 될 것으로 판단된다.

Recently, wetland and paddy wetland are being highlighted as the international environmental issues. However, research system which can assess paddy wetland is lacking. Thus, the purpose of this study is to assess the value of paddy wetland by applying RAM to paddy wetland. In addition, we would like to use this study as the data to establish assessment method for paddy wetland. 16 sites were selected as research targets based on altitude and soil. As the results of wetland assessment, 16 research target sites had total score of 212~227 and the average of 2.17~2.50. It was similar to those of Lacustrine Wetlands, Palustrine Wetland and Riverine Wetland which were sites in previous studies. The value could be recognized as the wetland. However, there was no difference in assessment results based on altitude and soil. It was found that all conservation values were the same. The factor the most closely affecting conservation value was the area. However, there was limitation to apply existing wetland assessment system to paddy wetland. In order to assess paddy wetland, factors such as rice farming methods, topography, vegetation, growth environment and biodiversity should be added. It was thought to supplement wetland assessment system through various further studies.

This study aims to provide basic data for the decision-making process in selecting sites for wetland restoration projects. To this end, the current list of demaged wetlands was identified based on the findings from the nationwide monitoring project in 2016 targeted at wetlands in inland areas. Then, to determine the necessity of restoration for these demaged sites, the cause of demage was investigated, and their conservation value was examined from an ecological and legal perspective. The 2016 monitoring project identified a total of 20 demaged wetlands, of which one site was deemed to have high conservation value through analysis of its ecological and legal values and on-site reviews. The results of this study are expected to support policymakers' decision-making in selecting wetlands for restoration projects since it identifies priority sites among demaged wetlands that require immediate restoration efforts. It should also be pointed out that wetlands in South Korea cannot benefit from legal protection despite their high conservation value unless they have a designated status as protected areas.

This study reports newly discovered seven forest wetlands in the western part of the Korean Demilitarized Zone-Civilian Control Zone ecoregion. The wetland assessment criteria proposed by National Arboretum were adopted to evaluate four fields: vegetation and landscape, biogeochemical cycle, hydraulics and hydrology, and social-cultural-historical landscape and disturbances. Among seven wetlands located in Gimpo and Paju, five were of the fallow field type and two were of the natural type. A total of 474 plant species were recorded, including nine rare plants, such as the Carex capricornis Meinsh. ex Maxim. Three forest wetlands were sorted into A-grade, three into B-grade, and one into C-grade. Monitoring forest wetlands scattered across the border area ruled by military regulations can be challenging; still, as forest wetlands with high conservation value turned out, further investigations through remote sensing and cooperation by the relevant agencies will be required.

This study was conducted to identify the distribution characteristics of small village wetlands in Geumsan County, an inland mountain zone, and comparing with Seocheon County, a coastal plain area with different ecological environment characteristics. Using Arc-GIS (v10.1) the village wetland code was extracted to derive the possible location of the village wetland, and the final distribution of the village was obtained by performing indoor judging work based on satellite images, aerial photographs, topographical maps, Korea Land Information System (KLIS), land use level, land cover degree (division), and land use status by local surveying and indoor analyzing. Although Geumsan County (576.66km2) is more than 60% larger than Seocheon County (358.04km2), 607 villages in Geumsan County and 570 villages in Seocheon County are capable of making similar levels of 106.5% of wetlands, but only a fraction of those in Seocheon County were found to be 67.6%. The density of the village wetlands was much lower than that of Seocheon County, a coastal plain area, because there were many mountainous areas in Geumsan County, and most of the wetlands temporarily created for water supply were removed during the analysis phase of the Jeongsa Image, so the actual wetlands of the village were judged to be only two-thirds different from those of Seocheon County.
