摘　　要：从纳潮量、潮流场、余流和波浪4个因素分析防城港钢铁项目的围填海工程对附近海域水动力环境的影响。认为围填海工程所引起的海流、波浪、纳潮量等因素的变化均较小,纳潮量最大减小8%,海流的流速流向只在工程附近发生变化,波浪在SE向有所减弱。这些变化对当地的海洋生态环境、船舶航行和生产活动等还不会构成威胁。The effect of coast reclamation works on hydraulic condition in nearby sea area of Fangchenggang have been analyzed through volume of tidal prism, tidal current field, residual current and waves. Analysis result showed that variations of four factors are less. The max decrease of volume of tidal prism is 8~/oo. Velocity and direction of ocean current changes only around the project place. Waves at SE direction is weaken. However, all these changes won＇t threaten ocean ecology environment, navigation of ship, procreation and activity.
