中文摘要：

浅海人工岛建设改变了周边海洋环境动力边界条件,引起周边海域泥沙冲淤变化。对卫星遥感数据和地形测量数据进行了对比分析,结合研究区风浪、潮流、悬浮泥沙分析了海底地形变化原因,研究了周边海域的泥沙冲淤规律,并对淤积和侵蚀的程度进行了量化评价,提出可以对护岛潜堤进行优化设计,此研究对类似浅海人工岛建设具有指导作用。

英文摘要：

The construction of artificial island is an effective factor in modification of the dynamic boundary conditions of an engineering area. Upon the comparison of the satellite remote sensing data and the topographic survey data, we discussed the submarine topography change o~ the study area in combination of the data of wave, tide, suspended sediments of the region. Depositional and erosional pattern was discussed quantitatively. Submerged breakwaters were suggested for protection of the ar- tificial island. The countermeasure could be adopted for other areas with similar boundary conditions.
