A 10km long section composed of 39 drilling holes in the central Jiangsu is examined to reconstruct the history of the coastaldevelopment and environmental evolution. There appears some evidences that modern tidal flat in central Jiangsu developed fromHolocene tidal sand ridges in the past centuries. A hiatus of sedimentation occurred between 20 and 10 ka BP. because of the lowerstand of sea level. Tidal flat occured in the modern coastal zone or nearshore during 30-20 ka BP.
