| 摘 要： | 竺山湖底泥疏浚表层50 cm模拟试验表明,疏浚与对照柱间隙水PO43--P浓度分别为3.6～40.8和9.2～715.6μg/L,沉积物-水界面PO34--P通量分别为-234.5～26.7μg/（m2.d）和-214.9～2 885.6μg/（m2.d）,疏浚间隙水PO34--P浓度和沉积物-水界面PO43--P通量与未疏浚相比下降明显,说明底泥疏浚对竺山湖内源磷释放具有极好的控制作用。

| Abstract: | As found in the simulation experiment on the 50cm surface layer of sediment dredging in Zhushan Lake,the PO3-4-P concentration of the dredged and the undredged interstitial water were 3.6-40.8 μg/L and 9.2-715.6 μg/L respectively,and the PO3-4-P flux of the sediment-water interface was-234.5-26.7 μg/(m2·d) and-214.9-2 885.6 μg/(m2·d) respectively.The PO3-4-P concentration of the dredged interstitial water and the PO3-4-P flux of the sediment-water interface were all lower than that of the undredged control,which indicated that the sediment dredging could better control the release of internal phosphorous in Zhushan Lake. |
