| 摘 要： | 采用筛析法分析了套子湾中滩面上66个表层样品的粒度。结果表明:套子湾海滩沉积物为中、细砂,为典型海滩砂。标准偏差较小,分选较好至好;频率曲线呈近正态分布,稍呈负偏;峰度中等至较窄。平均粒径和标准偏差由夹河口向东西两侧海滩变小,由于突堤的阻挡,海滩沿岸沉积物在突堤东侧产生堆积,西侧侵蚀。粒度特征和海滩地貌变化显示:套子湾海滩沉积物是由夹河口向东西两侧发生沿岸运移。为烟台开发区海水浴场的海滩养护以及芝罘岛连岛沙坝海岸的合理利用提供科学依据。

| Abstract: | Sieve analysis method has been adopted to get the grain-size characters of 66 samples which picked from the surface layer on the beach of Taozi Bay,and the result indicates: The sediments on the beach of Taozi Bay are mediumfine sands,standard deviations are small,they normally have a good sorting,and are symmetrical or a little negatively skewed and the single modal of grain-size distribution was built.The sediments are typical beach sands.Grain-size diameters and standard deviations decrease normally from the mouth of the Jiahe River towards East and West along the Taozi Bay beach.Owing to the jetty interrupt,sediments along the beach deposit in the eastern and make erosion in the western of the jetty.The characteristics of grain-size and the beach topography reveal that the sediment transport direction along the Taozi Bay beach is from the mouth of the Jiahe River towards respectively east and west sides.This research is the scientific basis of how to protect the beach at the bathing-beach of Development Zone in Yantai,and also the basis of how to utilize the coast of Zhifu Island tombolo in reason. |
