A phytosociological study on the hierarchical classification system of the Rosetalia rugosae, developed at the coastal dunes in the cool-temperate region of Northeast Asia, was carried out. Currently, the Rosetalia rugosae is subordinated to the Rosetea multiflorae which is the highest rank of the mantle vegetation in Northeast Asia, however its hierarchical system is somewhat ambiguous. This study was accomplished by using the syntaxa and hierarchical system of the Rosetalia rugosae and Rosetea multiflorae, and by also using 197 homogeneous relevns of the Rosetalia rugosae in South Korea and Japan in terms of the Zbrich-Montpellier School. For the hierarchical analysis of the Rosetalia rugosae, the constancy, the frequency and the net contribution degree were evaluated. It is estimated that the Rosetalia rugosae and the Rosetea multiflorae are hardly related to reciprocally. Thus, the subordination of the Rosetalia rugosae to the Rosetea multiflorae is comparatively irrational. Accordingly, the syntaxonomical hierarchy of the Rosetalia rugosae must be reconsidered that is correspond to the Viticetea rotundifoliae of the warm-temperate coastal dune shrub vegetation.

제주도 북제주군 한림읍 협재리에는 대부분 탄산염퇴적물로 이루어진 해안사구가 분포하고 있다. 사구를 이루는 탄산염퇴적물은 연체동물과 홍조류의 조각이 약 80% 이상을 차지하며 그 외에 저서성 유공충, 성게류와 태선동물의 조각, 그리고 화산암편으로 이루어져 있어, 제주도에 분포하는 여러 탄산염 해빈퇴적물의 입자조성과 매우 유사한 경향을 나타낸다. 이러한 탄산염 입자들은 천해에 서식하던 해양생물들에 의해 생성되며, 그 각질이 해빈으로 운반되고 바람에 의해 재동되어 사구를 형성하였다. 특히 이 연구지역의 사구가 분포하는 지점에서 북쪽으로 약 1km 떨어져 있는 협재 해수욕장에는 현재에도 천해에서 생성된 많은 양의 탄산염 해빈퇴적물이 퇴적되어 있으며, 제주도의 타 지역에 비해 매우 빠른 북동${\sim}$북서방향의 바람이 불고 있어, 퇴적물을 해빈에서부터 사구형성지점으로 운반시키는 데 효과적인 역할을 했을 것으로 판단된다. 사구를 절개하여 그 단면을 관찰한 결과, 전반적으로 희미한 수평층리와 사층리가 발달하고 있으며, 그 외의 다른 뚜렷한 퇴적구조는 관찰되지 않는다. 퇴적물의 입자들은 주로 직경이 $0.27{\sim}0.40mm$로 중립질 모래에 해당한다. 이 크기의 입자들은 가장 침식이 잘 될 수 있는 입자크기에 해당하는 것으로 알려져 있으며, 따라서 해빈으로부터 퇴적물이 운반될 때에 특히 이 크기의 입자들이 차별적으로 더 많이 운반되었을 것이라고 생각된다. 또한 퇴적물 입자의 크기와 구성성분의 함량은 각 사구의 전 층준에서 크게 변화하지 않는 것으로 나타나며, 이는 사구가 형성되는 기간 동안 탄산염퇴적물을 운반한 바람의 세기가 어느 정도 일정하였음을 지시한다. 해안사구의 형성시기를 알아보기 위하여 사구의 기반을 이루는 고토양층과 사구 최하부와 최상부의 탄산염퇴적물에 대해 방사성탄소연대측정을 실시하였다. 그 결과, 사구의 형성시기를 지시하는 고토양의 연령은 $680{\sim}720\;BP\;(1,200{\sim}1,300\;AD)$로 측정되었으며, 사구를 이루는 탄산염퇴적물의 연령은 전 층준에서 모두 약 3,500 BP로 측정되었다. 따라서 약 3,500 BP에 천해에서 생성된 탄산염퇴적물이 해빈에 분포하다가 $1,200{\sim}1,300\;AD$에 바람에 의해 재동되고 현재의 위치에 쌓여 사구를 형성한 것이라고 해석할 수 있다. 사구가 형성되기 시작하던 시기는 전세계적으로 춥고 바람이 세었던 Little Ice Age ($1,300{\sim}1,820\;AD$)에 해당하며, 따라서 해빈에 분포하던 많은 양의 탄산염퇴적물이 이 시기에 집중적으로 운반된 것으로 사료된다.

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.

Topographic changes in the foredune in Sohwang-ri, Boryeong, Chungnam Province was analyzed over the last two years. Seven cross-sections and one permanent plot ($20m{\times}50m$) were periodically studied based on erosion and deposition measurement, in addition to vegetation monitoring and measurement of wind using an automatic weather station. The sand dunes usually grew from late winter to spring and the growth occurred in a period of strong northwesterly winds. From March to April, heavy sedimentation was observed on the front section of the foredune and sand piled up to ca. 30cm to the ca. 25m landward from the high tide line. It is likely that increased wind force and growth of vegetation played a major role in transportation and sedimentation of sand. Meanwhile, the lower part of the sand dunes was eroded when typhoon and spring tide caused a rise in sea level. The transition zone of beach and dune was usually affected by sea water but some frontal slopes were entirely influenced, resulting in dune scarps. The eroded scarps were naturally restored to their original state as time passed.

There have been growing concerns for the sea level rise due to global warming in recent years. Sea level rise is a serious problem to densely populated coastal areas, because it may affect the coastal landforms to be damaged. Especially coastal sand deposits like coastal dunes are more sensitive than the other coastal landforms. In this paper, Ground Penetrating Radar (GPR) and Optically Stimulated Luminescence (OSL) dating method were used to identify the Holocene geomorphic changes of coastal dune field in Shinduri located at the western coast. The main results in this study that are the dunefield in the study area may have begun to form at around 6.8 ka and it has grown seaward thereafter. Then, dunefield appears to have extensively developed since 3.7 ka. This result, together with previous works on the sea level and climatic changes in the western coast of Korea suggest that the dunefield has been affected by the sea level regression since the Holocene high stand in the Holocene at around 6 ka and climatic change from warm and humid to cold and dry conditions occurred at 4.5 ka.

전통적으로, 토양은 식생의 분포를 결정짓는 중요한 변수로서, 생태 시스템의 보존과 관리를 위해서는 토양의 성질과 그 공간적 분포에 대한 이해가 선행되어야 한다고 알려져 왔다. 특히, 기질(substrate)이 사질 입자로 구성된 해안사구 생태 시스템은 영양소의 자체적인 생산이 충분하지 못하므로, 외부로부터 유입되는 영양소가 식생의 진입과 서식을 위한 필수적인 요소이다. (중략)

This study conducted surveys to identify the distribution of communities and flora according to vegetation in the coastal sand dunes of Sagye in Jeju Special Self-Governing Province, located at the southernmost tip of Korea. The survey was conducted over 20 sessions from April 2020 to October 2021. As a result of the study, physiognomy was classified into six correlated vegetation types: plant communities on the salt marsh, annual communities on a coastal drift-line, herb communities on a dune, shrub communities on a coastal dune, forest-edge communities on a dune, and artificial afforestation vegetation. The survey identified 43 communities, and a total of 212 taxa were found to be distributed among 62 families, 166 genera, 191 species, 15 varieties, 3 subspecies, and 3 forma. It was found that there were five rare plant taxa distributed in the area, including the Cymbidium macrorrhizum which was classified as an endangered Class II plant by the Ministry of Environment. Floristic target species identified by the surveys included 2 taxa for grade V, 5 taxa for grade IV, 15 taxa for grade III, 14 taxa for grade II, and 19 taxa for grade I. Climate-sensitive biological indicator species included 11 indicator and 2 candidate species, representing a high ratio of 33.3% of all indicator species and 15.4% of candidate species. Naturalized plants included 16 families, 43 genera, and 52 taxa, with a naturalization rate of 21.1% and an urbanization index of 24.5%. It is expected that these results will be widely used as data needed to prepare conservation and management measures for biodiversity in response to climate change in coastal dunes in the future.
