基于FVCOM模型,建立磨刀门海域枯水期三维盐度扩散数学模型,研究磨刀门海域咸潮上溯规律,并在分析磨刀门海域三维盐度扩散特征的基础上,考虑磨刀门水道航道疏浚工程,研究工程对该海域咸潮上溯的影响。结果表明,航道疏浚工程后,咸潮上溯的距离有所增大,但对非工程区域影响不大,不是影响磨刀门海域咸潮上溯的主要原因。
Based on the FVCOM model, a mathematical model of three-dimensional salinity diffusion in dry season of Shaodonghai seawater area is established to study the upstream traps of salt water in Shaodaomen sea area. Based on the analysis of the three-dimensional salinity diffusion characteristics in Shaodaomen sea area, Impact of Engineering and Research Projects on Upstream Traces of Saltwater in the Sea. The results show that after the channel dredging project, the distance of salt water upstream increases slightly, but it has little effect on the non-engineering area, which is not the main reason that affects the upstream of salt water in the Shaodaomen sea area.
