摘    要:通过对研究区潮间带36个表层沉积物的定位采样,采用综合法对样品进行粒度分析。结果表明,研究区潮间带表层沉积物由-粉砂质极细砂、极细砂-粉砂-粘土、粉砂-粘土-极细砂、极细砂质粉砂、极细砂-粉砂、粉砂和极细砂组成,从岸边向潮下带方向表层沉积物由细变粗;由于修建海滨浴场,改变了岸线的轮廓使水流发生变化,从驴驹河-独流减河潮间带表层沉积物粒度由粗变细;垂向上,由于修建海防公路造成岸线后退,沉积物表现为下粗上细,这些特征与本地区的人类活动和水动力条件变化密切相关。

关 键 词:天津  潮间带  沉积物  粒度

Abstract:Thirty-six surface sediments in the tidal zone have been positioned and sampled, and the samples have been analyzed by the integrated method. The results show that the surface sediments in the tidal zone consist of muddy silt and fine sand, and they gradually become coarse grain from the shore to the subtidal zone. The surface sediment grains change from coarse to fine between Luju River and Duliujian River. The reason is that the outline of the shore changes the water current as a result of building the shore bathing beach. Vertically, the sediments are coarse at the bottom and fine at the upper part, because the coastal defense road has been built and the coastal line has retreated to the sea. These characters are closely related to the human activity and the change of hydrodynamic conditions.
Keywords:Tianjin  Tidal zone  Sediment  Granularity
