Abstract: In order to establish relative analysis methods and find out transfer rules and vertical distribution characteristics of heavy metals in sediments of Poyang lake,column form sampler designed by us was used in the experiments,the sediments samples from Wucheng section of the Ganjiang River in Poyang lake area were collected using adjacent water vertical spile method.The sample's concentrations of Cu in different depth were determined by microwave digestion-atomic absorption analysis type of AS-990 analysis system.The results showed that vertical distribution and chronological characteristics were closely related and presented serration change.The parameter of depositional rate could be generalized as the relationship between chronological distribution and the depth of sediment.
