210Pb dating has determined modern sedimentation rate for 9 cores from Bohai Bay. It is found that sedimentation rate is relatively high off the Haihe River mouth (generally over 15mm/yr, and even up to 40-50mm/yr near the bay apex), and gradually decreases in anchorage and outer sea area, usually less than 8mm/yr. Radioactive profiles of the sediments have revealed important events in modern sedimentary environments, core column at site 1041 records the time of the Huanghe River flood and channel changes; and 210Pb profile from site 844 reflects the"instant accumulation"caused by human activities. We think that studies of modern sedimentation rate can be able to unco ver both man-made and natural events and this is very significant to ocean development engineering and scientific researches of environment.
