| 摘要: |
| 海底沙体是海洋资源开发利用、环境保护、灾害防治和军事行动等必须密切关注的底质类型。台湾海峡沙体面积分布广泛，主要有台湾浅滩、台中浅滩及海峡内受中小型山溪性河流影响的沙体。近年来，台湾浅滩沙体空间分布、大型沙波与小型沙波形态特征及剖面结构研究等领域取得了许多新进展；台中浅滩不同区域的沙体演化对应了地貌发育的不同阶段；而海峡西侧陆架上残留的中小河流沙体地貌也获得了一些新发现。本文归纳了台湾海峡窄陆架上不同沙体的平面分布特征、剖面结构及成因。今后工作的重点应聚焦于进一步获取不同区域高分辨率的地层、地貌证据，并进行对比研究。这些工作能深化对末次盛冰期以来台湾海峡不同地区沙体成因、关联及演化的认识，并有助于了解人类海洋活动与海底沙体演化的响应关系，丰富海底沙体发育和演化理论。 |

| Abstract: |
| Submarine sand has an important significance in the marine resources, environment, disasters and military. And it widely distributes in Taiwan Strait, such as Taiwan Shoal, Taizhong Shoal and nearshore area affected by small mountain rivers. In recent years, there is some progress in spatial distribution and characteristics of submarine sand, as well as the stratum profile in Taiwan Shoal; diverse characteristics of submarine sands in Taizhong Shoal are corresponding to different evolution stages. Some residual sand ridges formed by small mountain rivers on the west side of Taiwan Strait have been recently discovered. The space distribution, profile stratum and formation of submarine sand have been reviewed and summarized on the narrow continental shelf of Taiwan Strait. High-resolution stratigraphic and geomorphic evidences in different regions and synthetic study are suggested in the future study. It will be helpful for understanding the origin, correlation and evolution of submarine sand in different region of the Taiwan Strait since the last glacial maximum. This work contributes to the study of the response between marine activities and evolution of submarine sand, as well as the development and evolution theory of submarine sand. |
