This study aimed to suggest the directions for the landscape protection of Sindu-ri coastal dune based on its ecological system. The study investigated ecological systems of the coastal dune followed by damage causes of coastal dune according to the land use change, and landscape value of coastal dune in the study area. In order to construct causal-effect feedback loop, systems thinking was performed. Result of this study showed that the area of coastal dune and the amount of sand are maintained by the interaction with sand beach while they are affected by wind direction, wind speed, and dune plants. It was also found that the changes of land use pattern, increasing commercial area, and planted windbreak forest damaged to the coastal dune. In addition, size of coastal dune and growing number of dune plants increased landscape value of coastal dune and tourist draw. However increasing tourists have constantly affected land use changes and have damaged to coastal dune area. In sum, planning for land use regulation, rest-year system areas, promotion and education for coastal dune, dune plants protection, and windbreak management should be taken into account for landscape protection in coastal dune.

본 연구는 마을숲 연구에서 심도있게 다루어지지 않았던 해안 마을숲의 문화경관 특성을 파악하고, 그 가치와 정체성을 규명하고자 하였다. 경상남도 소재의 남해안 마을숲 10개소를 연구 대상으로 진행하였으며, 문헌연구, 현장조사, 인터뷰를 통해서 남해안 마을숲을 고찰하였다. 연구를 통하여 밝혀진 남해안 마을숲의 문화경관 특성은 문화적 특성, 실용적 특성, 경관적 특성으로 요약할 수 있다. 첫째, 내륙 마을숲이 유교적 배경이 강한데 비해 민촌에 조성된 해안 마을숲은 민간신앙의 영향이 두드러진 마을 공동체의 정신적 공간이다. 둘째, 남해안 마을숲은 해안마을이 접한 현실적 문제 해결과 경제적 효율을 우위에 둔 사고와 문화를 반영한 실용적 공간이다. 셋째, 남해안 마을숲은 단순히 수목으로 구성된 숲에 국한하는 것이 아니라, 주변 토지이용을 구성하는 바다부터 마을과 배후 산까지 광역적 범위에서 경관적 정체성이 이해되어야 한다. 본 연구는 그동안 주목받지 못했던 남해안 마을숲의 기초 자료를 구축하고, 내륙 마을숲과 차별화되는 해안 마을숲의 가치를 제고하였음에 의의를 지닌다. 나아가 동해안과 서해안 마을숲으로 연구의 대상을 확장함으로써 각 해안 마을숲의 특성과 차이점을 밝히는 연구가 후속되어야 할 것이다.

본 연구는 한반도 해안림의 가치와 중요성을 인식하기 위하여 우리나라 해안림의 조성과 관리에 대한 역사, 목적, 주체, 대상지, 규모, 조성방법, 식재수종, 식재지반, 층위구조, 관리제도 등에 대하여 이론적 고찰을 하였다. 해안가의 주민들은 삶의 터인 정주지에 당면한 바닷가의 잦은 자연재해로부터 안전과 풍수지리학적 경관의 비보를 위하여 해안림을 조성하였고, 관청은 자연재해나 군사목적으로 조성하고 관리하였다. 한반도의 해안림은 기록상으로 고려시대와 이조시대에는 민간과 관청이 주도적으로 조성하고 관리하였으나 1970년대 후부터는 민간, 관청, NGO단체, 종교단체, 기업 등이 참여하고 있다. 해안림의 조성과 관리는 기본적으로 해안가의 재난방지, 풍수적 비보, 군사적 이용, 목재생산을 위하여 조성되었지만, 부대적으로 신앙의 장소, 질병감소, 화재의 감소, 임산물 생산성의 증가, 어류의 증가, 풍치 경관 쾌적성의 향상, 관광객과 이주자의 증가, 문화예술의 동기부여, 휴식, 심신단련의 장, 공동체 결속, 전통문화의 계승, 교육, 생물의 서식처, 생물이동통로, 생물다양성 등의 효과가 있는 것으로 파악되었다. 해안가로부터 재난의 경험이 많은 사람들은 해안림 보전에 대한 인식이 강하고, 해안림을 자자손손 대대로 물려주어야 할 유산으로 생각하고 있다. 해안림은 학술적 측면에서 인문, 사회, 문화, 생물, 생태, 풍치적 이용 등에 대한 학술적 가치가 매우 높다. 한반도 해안림은 한번 훼손되면 다시 회복되기 어려운 환경압이 높으므로 자자손손 후대에 온전하게 물려주어야 할 사명으로 관리하고 보전해야 함을 시사하고 있다. 본 연구는 한반도 해안림에 대한 이론적 고찰에 국한된 것으로 실상을 면밀하게 파악하는데 한계가 있다. 따라서 향후 우리나라 해안림에 대한 조성과 관리 그리고 민속과 문화 등에 대하여 보다 구체적인 현장조사를 통한 연구가 필요하다.

To reduce the damage from the coastal disaster such as typhoon and tsunami, a possible option is the eco-friendly approach to minimize the destruction of ecological system. One of feasible idea is the forest for damage prevention artificially arranged along the beach. To understand a precise physics on the flow before and after the forest, we use a CFD method. In this paper, a three-dimensional numerical model has been constructed based on tree cases in a real forest located at Byin-myeon, Seocheon-gun, Chungnam. The CFD computation using a commercial code COMSOL multiphysics is performed for the distribution of real spatial coordinate of each tree. Through this investigation, the CFD techniques are shown to be applied to the research of forest composition plan. The physics in the regime from laminar to turbulent flow is qualitatively explained, and the obtained data are compared one another quantitatively.

South Korea has about 80 permanent GPS stations, being used for a variety of applications such as DGPS, RTK, survey and geodesy. Some of them are installed in or near the coastal area for the purpose of maritime navigation. But, until recently, none of them are used for tide gauge benchmark monitoring. In order to monitor the absolute sea level changes, it is necessary to monitor the land uplift or subsidence occurring at tide gauge sites. It is a common practice to use GPS stations installed at tide gauges to determine absolute sea level. This collaborative efforts coordinated by IGS are called TIGA Pilot Project. Many countries including U.S., Canada, European Union nations, Australia and Japan are participating in TIGA, but South Korea is not a member yet. Recently, we established continuously operating GPS stations at tide gauges located in Incheon and Jeju to monitor the movement of tide gauges sites. This paper will introduce goals and progress of the efforts.

The purpose of this study is to investigate and analyze a conservation state and a sustainable use of coastal wetland in Sindu-ri Tae-an, using the plant community structure analysis and the awareness result of local residents by published paper. To investigate a forest structure in Sindu-ri area, twenty plots were set up and surveyed. The community, is divided by three groups. The divided groups are Robinia pseudoacacia(I), Pinus thunbergii-Robinia pseudoacacia(II), Robinia pseudoacacia(III). Survey site I is simple canopy layer and deteriorative forest. Survey site II is grassland and swamp, where Pinus thunbergii-Robinia pseudoacacia is dominant trees of vegetation. Robinia pseudoacacia is competition species with Pinus thunbergii in survey site II. Survey site III is barren land(sand-hill) where main species is Robinia pseudoacacia. As a result, survey II district is considered as the most suitable for the conservation of species diversity. It is proposed in this paper that the ecological nature trail would be connected in survey site I and II for environmental education. The local residents of Tae-an, where natural environment is well-conserved, prefer conservation to development of the region. In case of Tae-an, where the condition of the natural environment is well conserved and the development potential exists, the development is in harmony with the environmental education program.

Coastal sand dune area is the important ecosystem as an ecotone which located between coastal area and terrestrial area. Moreover, it is very complicate landscape that have geomorphological interaction between erosion and accumulation of sand. Therefore, it is necessary to understand the sand dune ecosystem in view point of landscape scale including background landscape affecting origin of sand dune. Landscape ecological approach in the complicate ecosystem already started in developed countries, and it is applied to land management and biodiversity conservation strategies even in national scale. In this paper, landscape ecological analysis using landscape pattern analysis was carried out on 7 study areas (Yellow Sea : Hakampo and Doksan, South Sea : Namyeol and Balpo, East Sea : Hosan, Hupo and Goraebul) in Korean coastal sand dune ecosystem. Landscape elements were composed by 9 elements in these study areas. Major background landscape elements was the forest land and agricultural field. Namyeol (S06) has larger patch landscape compare to other areas. In patch shape indices, Hupo (E10) shows more complicate patch shapes. The high landscape heterogeneity showed in the Doksan sand dune area and that of Hosan. It shows that these areas were composed by various patch types. However, using landscape indices have to use very carefully because several variables have influence to the result such as scale and spatial pattern of study areas. Although landscape analysis through landscape indices shows sometimes difficult to explain the ecosystem, landscape scale approach on ecosystem assessment still useful to interpret in ecological process in large range of habitat.

North Korea is carrying out reclamation activities in tidal flat areas distributed throughout the west coast. Previousremote sensing research on North Korean tidal flats either failsto reflect recent trends or focuses on identifying and analyzing tidal flats. Thisstudy aimsto quantify the impact of recent reclamation activitiesin North Korea's coastal areas and contribute knowledge useful for determining the best remote sensing methods for coastal areas with limited accessibility, such as those in North Korea. Using Landsat-8 OLI images from 2014-2022, we analyzed land cover changesin an area on the west coast of Pyeonganbuk-do where reclamation activities are underway. Unsupervised classification using the normalized difference water index and the random forest classification technique were each used to divide the study area into classification groups, and changes in their areas over time were analyzed. The resultsshow a clear decrease in the water area and a tendency to increase cultivated area,supporting the evidence that North Korea'sreclamation isfor agricultural land expansion.Along coasts behind seawalls, the water area decreased by nearly half, and the cultivated area increased by over 2,300%, indicating significant changes and highlighting the anthropogenic nature of the cover changes due to reclamation. Both methods demonstrated high accuracy, making them suitable for detecting cover changes caused by reclamation. It is expected that further quality research will be conducted through the use of high-resolution satellite images and by combining data from multiple satellites in the future.
