해수 온도의 상승과 해양 오염의 증가로 근래 국내 해안에서도 갯녹음이 확산되면서 바다숲이 축소되고 있다. 특히, 온난류의 유입에 의한 무절 석회조류의 난입과 해수에 함유 농도가 증가한 칼슘이 석출되고 해저 암반을 뒤덮어 해조류의 포자 활착 공간을 없애는 백화현상이 확산되면서 바다의 사막화 현상이 가속화되고 있다. 본 연구에서는 해조류의 포자가 빠르게 활착하여 안전하게 생장할 수 있는 공간을 제공하기 위한 새로운 방안으로, 먼저 육상에서 모판의 기능을 제공하여 해조류의 포자를 착상하여 성장시킨 후 해저로 이식하는 것으로 바다숲과 해안의 환경을 효과적으로 복원하기 위한 방안으로 다공성 기질 생태 플랫폼을 디자인하고 이의 특성 및 활용 방안을 제시하였다.

As marine desertification and chlorosis in Korean coast have been intensified over time, Korean government is promoting marine afforestation projects. However, marine afforestation location is mainly decided by administrative convenience. Also, there is limited literature on location suitability about the marine afforestation. This study aims to assess location suitability of marine afforestation considering 3 significant criteria: ecological, submarine topographical, and human-social environment. Jeju, the study area of this study, first observed chlorosis in Korean coast at the small fishery town in Seogwipo. Jeju is currently suffering from chlorosis all around the island. Habitat Evaluation Procedure (HEP), 3D kriging, Analytic Hierarchy Process (AHP) is applied as analysis methods. Especially, 3D kriging is utilized for modeling 3D ocean space reflecting ocean environment appropriately. The result shows that Jocheon coast has better location suitability than Seogwipo Pyoseon coast. Jocheon coast has the maximum 61% suitability as the habitat of Ecklonia cava Kjellman, and is highly evaluated in other criteria. The results of this study are expected to find optimal marine afforestation location, and to contribute to the restoration of the Jeju coastal ecosystem and the revitalization of Jeju fishing village societies.

In this study, we located concrete substratum covered by oyster shells in the coastal area of Gijang-gun, Busan, South Korea, and monitored changes in coverage of macroalgae for approximately a year from January 2020 to determine the potential for sea forest restoration and resourceization of the oyster shells. At the start of monitoring, we observed that macroalgae coverage of the oyster-shell-covered concrete substratum (treatment) was 10 - 80 %, whereas no macroalgae were attached to the normal concrete substratum (control). By November, macroalgae coverage of the treatment had increased by 49 % compared to that of the control. We concluded that covering oyster shell on a sea forest reef can promote macroalgae establishment and the possibility of sea forest restoration by the resourceization of oyster shells.
