一、前言本区指以天津新港为中心,沿岸向东至南堡,往南到后唐铺。我们于一九八三年六至九月对本区潮间带和岸线以下零至-15米进行了历时三个月的野外动力地貌调查、底质表层取洋及沉积物样品的颗粒分析工作。本文主要根据沉积物的粒度、岸滩动力地貌和海洋水动力要素等资料,分析了渤海湾西部海区现代沉积特征和泥沙来源。 I. Preface The district refers to Tianjin Xingang as the center, coast to the east of Nanpu, south to Tang shop. We conducted a three-month field dynamical geomorphological survey from zero to -15 meters below the tidal zone and shoreline in this area between June and September 1983, taking sediment samples from the sediments and particle analysis of sediment samples . In this paper, the sedimentary characteristics and sediment source of the western Bohai Bay are analyzed based on the sediment particle size, the dynamic characteristics of shore and the hydrodynamic factors of the ocean.
