Abstract: The vertical distribution of total phosphorus (TP),the dissolved total phosphorus (DTP),the soluble reactive phosphorus (SRP),the suspended solid (SS) and its loss on ignition (LOI) in Taihu lake,a large,shallow,eutrophic lake,was observed in a strong wind course (with the wind speed of 12 m/s) and a light breeze course (with the wind speed of 3 m/s).The water depth of the observed site was 1.9 m.The concentrations of TP,DTP,SRP and SS at 10,90,140,and 190 cm below the water surface were monitored.The water-column mean concentration of SS in strong wind period was 468.8 mg/L±302.1 mg/L,which is 10 times higher than that in light breeze period,and the concentration of TP was 0.296 mg/L±0.081 mg/L,which is 3.6 times higher than that in light breeze period.However,the difference of the concentrations of DTP and SRP between strong wind period and light breeze period was insignificant 1 Additionally,both in the strong wind period and in the light breeze period,concentrations of SS and TP were insignificantly different among those in the upper three layers,and lower than those in the bottom layer.However,the concentrations of SRP were insignificantly different in the whole water column.The results indicate that,wind-induced wave not only cause the drastic sediment resuspension and the nutrient releasing,but also result in the absorption of dissolved reactive phosphorus.The sediment resuspension may not increase,but decrease the amount of the bio-available phosphorus in the water column.
