本文根据实测和历史资料对碣石潟湖口动力地貌演变进行综合研究,揭示了潟湖泥沙来源主要为SE—NW方向的沿岸漂沙,指出潮汐通道淤塞、弯曲和位移是由于潟湖在自然淤积和人为围筑的影响下,纳潮量减退,导致通道潮汐力减弱和波浪力成为控制因素的结果。最后对口门整治,如增大潟湖纳潮量、均衡通道过水断面积和防沙堤设置等问题提出意见。 Based on the measured and historical data, the dynamic geomorphological evolution of the Tieshi Lagoon Estuary is studied. The results show that the main source of sediment in the lagoon is the sand drifting along the coast of SE-NW. It is pointed out that the tidal channel is blocked and the bending and displacement are caused by natural sedimentation and man- Under the influence of enclosures, the amount of Nadu decreases, resulting in the channel tidal force weakened and the wave force as a result of control factors. Finally, rehabilitate the port, such as increasing the amount of lag lakes, crossing the cross-section of waterways and anti-dike set issues such as advice.
