Abstract: The effect of a floatingleaved macrophyte Trapa quadrispinosa Roxb on nitrogen resuspension from sediment was studied with sediment traps placed within (inner zone) and outside (outer zone) of the macrophyte stand in Lake Taihu. During the study period, the average sediment resuspension rate was 658.13 g dw m-2 day-1 in outer zone and 218.46 g dw m-2 day -1 in inner zone; With the resuspended sediment, 1 560.96 and 718.06 mg N m -2 day -1 was brought to the water column in outer zone and in inner zone respectively, suggesting that the nutrient loading due to sediment resuspension was considerable high in Lake Taihu. The results also revealed that the total nitrogen concentration of the upper sediment had a negative relationship to the sediment resuspesion rate. Thus it could be concluded that floatingleaved macrophyes are able to reduce nutrient resuspentsion significantly from sediment.

Key words: Lake Taihu, nitrogen resuspension, floatingleaved macrophyte
