根据冬、夏两季的潮滩沉积地貌现场观测，大小潮的悬沙含量、悬沙沉降量、沉积物活动层等测定，以及以往的海岸带调查资料，本文着重讨论了自岸向海高潮滩砂质、高潮滩砂泥混合质、中潮滩砂质、中潮滩砂泥混合质和低潮滩泥质５个沉积带的沉积动力作用，从而说明了十余年来潮滩沉积物以砂和粗粉砂级组分向岸、极细粉砂和粘土级组分向海为主的搬运过程。
According to the on-the-spot observation of the tidal flat sedimentary landscape in winter and summer, the suspended sediment content of large and small tides, the sedimentation of suspended sediment, the determination of the sediment activity layer, and the previous coastal survey data, Sediment dynamics of 5 sedimentary belts of beach sandy, tidal flat sandy mud and muddy, tidal flat sandy, tidal flat sand mud mixed and low tide beach mud show that sediments of tidal flat with sand and coarse Silt-grade components to the shore, very fine silt and clay-based components to the sea-based handling process.
