Benthic foraminifer fauna, ams14c dating and acoustic sub - bottom profile was analyzed in the core ey02 - 2 and ey02 - 1 drilled from the muddy deposit in the middle southern yellow sea and the mid - shelf of north east china sea. considering the results of core qc2 ? dz4 and the standard oxygen isotope curves, we discussed the late - quaterenary paleo - environment evolution, benthic foraminifer fauna, paleo - climate, the climate events and water mass in postglacial period, average sedimentation rates, paleo - water depth, origin of sediments, average sea level rise rate in the shelf of south yellow sea and east china sea. at last we discussed the condition of sea level rise in the east china, green house effect and the protection of coastal zone
