///The distribution characteristics and influencing mechanism of dissolved Cu, Pb, Zn, Cd, Cr in the Doliaohe estuary were analyzed and discussed, based on the surface water samples collected in July 2009 and April 2010, respectively. The results showed that the other concentrations of the heavy metals were ranged in the first-rate classification of the Daliaohe estuary except for Cu in April 2010. The concentrations of dissolved Cu, Pb, Zn, Cr in April 2010 were higher than those in July 2009. Concentrations of Cu, Cd and Cr increased gradually from the estuary to the sea in July 2009 and April 2010. The concentrations of Pb, Zn were higher in the Doliaohe estuary than marine area. The content and distribution of heavy metals were mainly controlled by the discharge of upstream water, tides and wind-wave.
