The objective of this study is to provide thecomparative analysis on sand deposition rate,sand particle sedimentation type, sedimentation amount in two different types of fixed structuresfor a coastal dune. Study site is located on the beach of coastal disaster prevention forest inPohang and the study period was from October 2014 to June 2016. This study compares andanalyzes the sand deposition during the three years. The results indicated that the average heightof sand sediment at the terraced retaining wall was 1.3 times greater than the one at the sandaccumulating fence. At the height of 0.5 m, the effect of wind speed reduction was 43.3% forterraced retaining wall and 32.2% for sand accumulating fence. The results of this study areexpected to be used as basis data for coastal sand dune formation and coastal forest formation. 이 연구는 사구 고정 구조물의 종류에 따라서 모래 퇴적속도, 형태, 퇴적량을 분석하여 해안복원 기초자료로 제공하기 위하여 수행되었다. 연구 대상지는 경상북도 포항시 북구 해안림이 조성된 해변 지역을 선정하였다. 계단식 옹벽과 퇴사울타리 설치 후 3년간(2014-2016) 모래퇴적을 모니터링하여 비교 분석하였다. 각 구조물의 모래퇴적을 분석한 결과, 평균 모래퇴적 높이는 계단식 옹벽이 퇴사울타리 보다 약 1.3배 더 퇴적되었다. 구조물의 풍속저감 효과는 0.5m 높이에서 계단식 옹벽이 43.3%, 퇴사울타리 32.2%로 나타났다. 이 연구의 결과는 앞으로 해안사구 조성 및 해안림 기반 조성의 기초자료로 활용될 것으로 기대된다.

The objective of this study was to select a representative coastal disaster prevention forest type foreach coastal area. In this study, we used cluster analysis with the results obtained from investigation for densityof growing stock, tree height, DBH, and forest width and length of major coastal disaster prevention forestsdistributed in the west, the south, and the east coasts. The results showed that the coastal disaster preventionforests for each coast were classified into two types: a forest type with small DBH and high growing stockdensity (W1) or with high tree height (W2) in the west coast, a forest type with small tree height (S1) or withlarge DBH (S2) in the south coast, and a forest type with small growing stock density (E1) or with small treeheight and low DBH (E2) in the east coast. The coastal disaster prevention forests located in Gurye beach(Hwangchon-ri, Wonbuk-myeon, Taean-gun, Chungcheongnam-do) and in Gohsapo beach (Unsna-ri, Byeonsanmyeon,Buan-gun, Jeollabuk-do) were selected as the representative forests of W1 and W2, respectively. Inaddition, the coastal disaster prevention forests located in Namyang beach (Namyang-ri, Seolcheon-myeon,Namhae-gun, Gyeongsangnam-do) and in Donggo beach (Donggo-ri, Sinji-myeon, Wando-gun, Jeollanam-do)were selected as the representative forests of S1 and S2, respectively. Last, the coastal disaster prevention forestslocated in Bonggil beach (Bonggil-ri, Yangbuk-myeon, Gyeongju-si, Gyeongsangbuk-do) and in Anmeok beach(Gyeonso-dong, Gangneung-si, Gangwon-do) were selected as the representative forests of E1 and E2,respectively. Our finding is expected to be used as baseline data in establishing the most appropriate coastaldisaster prevention forest for each coast.

Recent estimates show that land degradation is rapidly progressing worldwide. Therefore, efforts are being made in Korea toward Land Degradation Neutrality (LDN) to extend the development of green areas. As part of this effort, artificial ecosystems created through landuse changes are restored to forests. We examined grassland created through land-use change, an afforested site planted for forest restoration, and a nearby primary forest according to the LDN indicators. The grassland created about 40 years ago showed higher bulk density and available phosphorus compared to the forest and showed relatively low carbon and nitrogen contents. According to the assessment of LDN indicators, the soil organic carbon stock and productivity calculated from the normalized difference vegetation index of the afforested site for restoring the grassland to forest did not change. The assessment of the restoration effect was not made in the short-term, but in near future, the planted trees are expected to grow, restoring the land to forest. This study shows that the LDN program of Korea should follow carefully established restoration policies and strategies to achieve positive results.
