The remediation performances of heavy metals contaminaged sediment by hydrophytes including Alternanthera Philoxeroides, Canna indica L., Nymphaea tetragona, Typha orientalis, Phragmites australis, Phragmites australis, Hydrilla verticillata, Cyperus alternifolius L., Eichhornia crassipes, Acorus tatarinowii, Digitaria sanguinalis (L.) Scop were investigated through batch pot experiments. The results showed that the enrichment effect of Pb was better in Alternanthera Philoxeroides and Acorus tatarinowii with the BCFs of 4.42 and 1.22, and the TFs of 7.84 and 4.23, respectively. The Cr enrichment effects by Nymphaea tetragona, Hydrilla verticillata and Eichhornia crassipes (Mart.) Solms were better, which BCFs were 2.69, 1.91 and 3.71, and which TFs were 7.93, 2.07 and 2.18, respectively.
