| 摘要: |
| 文章基于2022年春、秋季开展的龙岐湾沙滩资源调查数据，分析较场尾沙滩、大塘角沙滩、黄泥湾沙滩和桔钓沙沙滩的剖面特征、沉积物粒径和裂流发生情况。研究结果表明：4处沙滩剖面的坡度秋缓春陡，剖面受风浪和潮汐直接作用时坡度变化大，受遮蔽时坡度变化小，整体呈冬春淤积、夏秋侵蚀；沙滩沉积物以中砂、粗砂和砾石为主，粒径变化不大；沙滩均无明显裂流发生，为低风险等级。建议开发沙滩旅游应考虑季节性的补沙方案，开展围垦养殖和海岸工程应注意削弱ESE向和SE向的波浪作用。 |

| Abstract: |
| Based on the data from the Longqi Bay beach resource survey conducted in the spring and autumn of 2022, the profile characteristics, sediment grain size, and rip current occurrence of Jiaochangwei, Datangjiao, Huangni Bay, and Judiaosha beaches were analyzed. The results demonstrated that the slopes of four beach profiles were smaller in autumn and larger in spring, and the slopes of the profiles varied greatly when they were directly affected by wave and tide, and less when they were sheltered. The beach as a whole showed siltation in winter and spring, and erosion in summer and autumn. The beach sediment was mainly medium sand, coarse sand, and gravel, with little change in grain size. No obvious rip current occurred on the four beaches, which were evaluated as low hazard levels. It was suggested that seasonal beach nourishment should be considered in the development of beach tourism , and the ESE and SE waves should be weakened in the development of reclamation and aquaculture, and coastal engineering. |
