外文摘要：In order to research the change and distribution characters of heavy metals in the sediment of estuary, sediment grain size, organic carbon and nitrogen, Acid volatile sulfide (AVS) and acid extracted metals(including Fe, Mn, Sr, Ba, Cr, V, and Co) were analyzed in six sediment short column cores collected from Licun estuary of Jiaozhou Bay. Under the background of intense sulfate reduction reaction induced by high flux of organic material inputtment, the cycle of Carbon, sulfur and metals is active the Licun Estuary of Jiaozhou Bay where influenced by continental material inputtment. Contents of heavy metal extracted by acid (6 mol/L HCI) present in an order as Fe > Mn > Sr > Ba > Cr > V > Co. In JZB1 and JZB2 near the estuary, the metals extracted by acid have good relativity among them and are influenced by sulfide distribution. It indicates that those metals have similar geochemistry behavior in the process of sulfur cycle under condition of high intensive sulfur cycle with plenteous organic carbon suppliment. Grain size effect is obviouse in JZB6 far away from estuary. It indicates that the source of material mainly is sdiment preservation in normal marine environment while the dissolved material play an important role in seidment geochemisty process at the area near the estuary.
