The ^210Pb activity was measured in cores B3, C2, C4, B6, D4 and D6 of the Jiaozhou Bay and the elements of Ca, K, Li, Mg, Na, Rb, Sr and V were measured in corresponding sediment layers. The results show that the model of ^210Pb distribution reflects the sedimentation rate and sedimentation environment in different region for Jiaozhou Bay. The vertical distributions of Ca, K, Li, Mg, Na, Rb, Sr and V in Jiaozhou Bay core sediments has obvious variety in different regions and at different stratigraphic time. The obvious change of accumulation rate which occurred in sedimentary course at present and foretime reveals the matter source and sedimentation environment of sampling stations, and reflects the influence of industrial and agricultural activity on Jiaozhou bay environment in recent 100 years.
