摘　　要：通过分析泉州湾自然条件,采用数学模型从水动力、流态、冲淤等方面讨论了泉州湾秀涂人工岛建成前后对水沙环境的影响。研究表明:人工岛建成后减少纳潮量约2%,归顺了人工岛周边水流流态,但对局部流场有一定影响;人工岛建成后固化了部分浅滩沙源,宏观冲淤影响幅度可控。可为类似工程的开发与保护提供参考。Based on the analysis of the natural conditions of Quanzhou Bay,this paper studies the impact of Xiutu artificial island on the hydrodynamic and sediment environment before and after its constraction by mathematical model from the aspects of hydrodynamic force,flow pattern,erosion and deposition.The results show that after the completion of the artificial island,the tidal capacity will be reduced by about 2%,which is in line with the flow pattern around the artificial island,but has some impact on the local flow field;some shoal sand sources will be solidified,and the macroscopical scouring and silting effects can be controlled.It can provide reference for the development and protection of similar projects.
