摘　　要：挖入式港池口门的束窄减小了港池水体进出的通道,使得内外水体交换率降低,导致港池内污染蓄积,问题日益突出。以江苏吕四边滩挖入式港池为例,采用对流扩散模型对该问题进行模拟研究,重点研究边滩挖入式港池水体交换特征以及平面布局上导流堤长度对港池水体交换的的影响。The narrow entrance of harbor basin reduces the rate of water exchange, which further results in severe environmental prob- lems in the harbor. The paper uses the convection - diffusion numerical model to investigate the water environment of a dredged harbor basin on radial sand ridges point bar, studies the characteristics of water exchange and the influence on water exchange by dyke outside basin.
