| Abstract: | In view of the problem that water purification effect of Potamogeton crispus,the main submerged plant in Lianshi Lake of Yongding River,in Beijing,was reduced due to succession in summer,Elodea canadensis Michx,Hydrilla verticillata,Vallisneria natans and Myriophyllum verticillatum L.were selected and its combinations study on purification effect of TN,TP,NH3-N,chlorophyll,DO and other water quality indicators.According to test results,combinations suitable for the succession of Potamogeton crispus in Lianshi Lake was selected.Results showed that four submerged plants and their combinations had better removal effect on TN,TP and NH3-N,and had obvious inhibition on chlorophyll.The best treatment capacity for TP was the combinations of Vallisneria natans+Hydrilla verticillata+Myriophyllum verticillatum L.,with an average treatment capacity of 11.11 mg per plant.The best treatment capacity for TN was the combinations of Elodea canadensis Michx+Hydrilla verticillata+Myriophyllum verticillatum L.,with an average treatment capacity of 141.36 mg per plant.The best treatment capacity for NH3-N was the combinations of Vallisneria natans+Hydrilla verticillata+Myriophyllum verticillatum L.,with an average treatment capacity of 96.12 mg per plant.Based on above situation,combined with the growth and characteristics of each plant,the combinations of Vallisneria natans+Hydrilla verticillata+Myriophyllum verticillatum L.was selected as the succession plan of Potamogeton crispus in summer in Lianshi Lake. |
