Abstract�� The purification by Eichhornia crassipe in ecological watercourse was examined in indoor laboratory.Circles in three different forms were used to enclose the Eichhornia crassipe.Water purifying efficiencies of Eichhornia crassipe were analyzed in different conditions.The results indicated that the water purifying efficiency Eichhornia crassipe was great and it was a viable hydrophyte in ecological watercourse,but the nutrition should be considered.If the nutrition was not enough for water hyacinth's absorption,the Eichhornis crassipe would perish after some days.From the analysis of hydrodynamics,when the frames were disposed and Eichhornia crassipe were planted in channel,flow in this channel was influenced.Model C had the most influence on flow's configuration.Model A and B had a little affection,which were suitable for water purifying.
