| 摘 要： | 基于现场实测水文泥沙资料和水深测图资料,对秦皇岛海域的水文泥沙特征进行了分析。分析结果表明:研究海区靠近半日潮无潮点,潮差小,潮流动力较弱,水体含沙量低,泥沙来源有限,泥沙运动不活跃,岸滩整体保持稳定。秦皇岛海域水文泥沙环境较好,为海岸带开发利用提供了良好的条件。研究成果可作为本海域海岸开发利用的基础资料和依据。

| Abstract: | In this paper,hydrodynamic and sediment characteristics in Qinhuangdao sea area were analyzed according to in situ hydrologic data,sediment data and bathymetric charts.The study results show that： （1） because of the nearby amphidromie point of semi-diurnal tide, tidal range of the sea area is very small, and tidal current is relatively weak; （2） the sediment sources are limited and the sediment concentration of sea water is very low; （3） the sediment movement along the seabed is not active,and the seabed profile basically keeps stable.Hydrographic and sediment environment is relatively good in Qinhuangdao sea area,which provides favourable conditions for coast development.The present results can be used as the basis data for development and utilization of Qinhuangdao sea area. |
