| 摘 要： | 通过对2006-2013年布设在涠洲岛的15条岸滩剖面3次重复测量和数据对比分析,发现涠洲岛岸线整体遭受侵蚀.岸滩剖面长期变化特征表明,涠洲岛东部与西南部海岸侵蚀较为严重,西南部岸段年均下蚀可达0.18 m;正北部岸滩海岸侵蚀程度相对较轻,南湾段海岸整体变化较小,呈现弱侵蚀弱淤积变化.在短期强热带风暴影响下,冬季至夏季岸滩下蚀明显.

| Abstract: | From the data contrast and three repeated measurements of 15 beach profiles laid around the Weizhou Island from 2006 to 2013, it has been found that the coast of the island is, as a whole, subjected to the erosion. The long term changes of the beach profiles have indicated that the erosion of the coast is more serious in the eastern and southwestern parts of the island, with the average annual down-erosion being 0. 18 m along the southwestern coast. The coastal erosion is relatively light in the northern beach. The coast around the South Bay changes slightly, showing a weakly eroding- weakly depositing state. Under the influence of short-term storm, the beaches of the island are eroded down significantly from winter to summer. |
