This paper mainly studies the purification effect of aquatic plant combination on eutrophic water body.In the experiment,Vallisneria natans(Lour.)H.Hara,Hydrilla verticillate,Lris hybrids'Louisiana'and Acorus calamus L.are selected as the research objects to construct a combination of submerged and emergent aquatic plants.By monitoring the four water quality indexes of total nitrogen,total phosphorus,chemical oxygen demand and dissolved oxygen,different experimental data were comprehensively evaluated and analyzed to study the purification effect of different aquatic plant communities on eutrophication water under indoor still water conditions.The results show that the purification efficiency of the combination of emergent plants and submerged plants is greater than that of the combination of single emergent plants or submerged plants,so the reasonable combination of submerged plants and emergent plants can effectively improve the purification efficiency of eutrophication and reduce water pollution.
