Abstract The growth paramerers of 11 wetland emerged plnts and their effects on water pollution purification were studied.The results showed that:(1) wetland emerged plants could purify the urban rivulet water pollution to some extent,Thalia dealbata,Alocasia Macrorrhizos,Canna generalis and Arundo donax had the most powerful capacity.(2) Waste water treatment could decrease the leaf area,growth height and total biomass of Iris pseudacorus and Scirpus tabernaemontani,therefore weakening their growth behavior.However,in the case of Alocasia macrorrhizos,Canna generalis,Vetiveria zizanioides and Ruellia brittoniana,the growth capacity increased at different extents.Thalia dealbata,Alocasia macrorrhizos,Canna generalis,Ruellia brittoniana,Cyperus alternifolius and Acorus calamus were suggested to be appropriate water pollution purification and landscape materials in Guangzhou urban rivulets.
