摘要
Core BF10 is nearby Bingfang middle school in Dayu Town of Rudong County, Nantong area of the north flank of Changjiang Delta. The analysis of Core BF10 is helping to understand the interaction between river and sea, between land and sea, between human and environments, and is conducive to recognize the environment evolution of Nantong area. Combined with the existing literatures and dating data, Core BF10 is divided into 5 parts from bottom to up: shallow marine I,shallow marine II, littoral, gulf and tidal flat. Shallow marine I sediments, which mainly consist of silt and sand, 96% and more of beyond medium sorting coefficient, show 3 parts in probability accumulation curves. The transport is mainly of scrolling and saltation, with C-M figure showing contain gradients and uniform suspension, medium strength of hydrodynamic.
