| 摘 要： | 对大纵湖底泥疏浚的短期效应进行模拟实验,分析了上覆水体的Eh、pH和磷质量浓度随时间的变化规律,以及沉积物中总磷、无机磷、有机磷、铁/铝磷、钙磷等5种形态磷质量比的垂向变化规律。结果表明:底泥疏浚30 cm对上覆水体Eh、pH以及磷浓度控制效果不显著,且沉积物磷形态不是影响沉积物释磷的主要因素。

| Abstract: | The short-term effect of sediment dredging on endogenous phosphorus release of the Dazong Lake was studied.The variation of Eh,pH and phosphorus content of overlying water with time,and the vertical change of mass ratio of TP,IP,OP,NAIP and AP in sediment phosphorus were analyzed,The results showed that the sediment dredging of 30 cm had no significant effect on the Eh,pH and phosphorus content of overlying water,and the form of phosphorus was not the significant influencing factor of phosphorus release in ... |
