Set 5 sample sections in a certain gully area in the tributary of Iton River from upstream to downstream of Changchun city, which locates in the northern part of China, then respectively collect sediments and soils which are proximal and distal away from the river bank, test the heavy metal content of Zn, Cu, Cd, Pb and conduct pollution assessment. The result shows that: the content of Zn in sediment is in the state of light pollution, Cu has an obvious accumulated tendency, Pb,Cd are basically in a state of local background value. Therefore, the pollution index of sediment is in a state of slightly pollution, the proximal bank-side is in the safe state, while the distal bank-side is in a state of alert. The main reasons that cause heavy metals pollution and accumulation are traffic and agricultural pollutions.
