海洋表层沉积的孢粉、藻类研究是海洋孢粉学中最重要的基础研究之一,为了探讨渤海西部表层沉积物中孢粉、藻类的分布规律,并以此为垂向剖面研究提供依据,笔者分析了滦河口两条剖面的14个样品(图1).滦河口第Ⅱ号剖面位于滦河口外,方位为南东51°;滦河口第Ⅳ号剖面位于乐亭县正南、大清河口外海区,方位南东19°.样品岩性为灰褐色、黄褐色细砂、粗粉砂和细粉砂,由岸向海沉积物粒径由大变小.
Pollen and algae deposited on the ocean surface are one of the most important basic studies in marine sporopollenology. In order to investigate the distribution of pollen and algae in the surface sediments of western Bohai Sea, and to provide the basis for vertical profile studies, The author analyzed 14 samples from two sections of Luanhekou (Figure 1). Section II of Luanhe Estuary is located outside Luanhe Estuary with a southeasterm of 51 ° South; section IV of Luanhe Estuary is located in the south of Laoting County, Occidental sea area, the location of the south-east 19 °. Samples of lithology as brown, yellowish brown sand, coarse silt and fine silt, sediment from the shore to the sea from the larger particle size.
