摘要

摘要: 为了解沉积物磷释放对水体磷污染的影响,以嘉兴市北部湖荡区为研究对象,结合薄膜扩散梯度技术(DGT)对湖荡区(汾湖、莲泗荡、北官荡)沉积物磷释放通量进行研究,分析磷释放影响因素,并对沉积物磷释放对上覆水体的影响进行了评估。结果表明:汾湖、莲泗荡和北官荡采样点沉积物-上覆水界面DGT-P(溶解性有效态磷)浓度总体表现为莲泗荡(0.735 mg∕L)>北官荡(0.154 mg∕L)>汾湖(0.077 mg∕L)。垂向分布上,3个湖荡采样点表层沉积物中DGT-P浓度均高于上覆水,但在沉积物-上覆水界面±10 mm范围内表现各不相同,其中汾湖采样点沉积物-上覆水界面DGT-P没有明显的浓度梯度,说明沉积物向上覆水释放磷能力较弱,而莲泗荡采样点呈现明显的浓度梯度,沉积物有较强的释放磷能力,北官荡采样点介于二者之间。各湖荡采样点沉积物-上覆水界面磷释放通量对上覆水体的影响有限,其中莲泗荡采样点磷释放通量最高,为0.490 mg∕(m ²·d),对上覆水体的贡献率也最大(1.93%),表现为磷“源”;其次为北官荡采样点,其磷释放通量为0.047 mg∕(m ²·d),对上覆水体的贡献率为0.24%;汾湖采样点磷释放通量接近0,表现为磷“汇”。相关性分析结果表明,铁氧化物还原溶解对沉积物-上覆水界面磷的迁移转化过程具有重要影响,同时有机质矿化过程对沉积物磷释放的影响也不容忽视。

Abstract: In order to understand the effect of phosphorus release from sediment on water pollution, the diffusive gradients in thin-films technique (DGT) was introduced to clarify phosphorus fluxes and its influencing factors in sediments in Fen Lake, Liansidang Lake and Beiguandang Lake in northern lacustrine areas of Jiaxing City. The effect of phosphorus release from sediment on overlying water was evaluated. The results showed that concentrations of soluble available phosphorus (DGT-P)in sediment water interface (SWI) displayed various trend at three sampling sites and generally showed the following decreasing order: Liansidang Lake (0.735 mg∕L) > Beiguandang Lake (0.154 mg∕L) > Fen Lake (0.077 mg∕L). In terms of vertical distribution, the concentrations of DGT-P in the surface sediments of the three lakes were higher than that of overlying water. But the situation was different within the range of ±10 mm at the SWI; there was no obvious concentration gradient of DGT-P at the SWI of Fen Lake, indicating that the phosphorus release capacity of sediments to overlying water was weak, while that of Liansidang Lake presented an obvious concentration gradient and had a strong phosphorus release capacity, and that of Beiguandang Lake was between the two. From the perspective of the phosphorus release fluxes at the SWI, the phosphorus release flux of each lake sediment had a limited effect on the overlying water. Among them, the phosphorus release flux at the Liansidang Lake SWI was the highest (0.490 mg∕(m ²·d)), and its contribution to overlying water was also the highest (1.93%), which showed the source of phosphorus. The second was Beiguandang Lake, whose phosphorus release flux was 0.047 mg∕(m ²·d), and its contribution to overlying water was 0.24%. The phosphorus release flux at the SWI of Fen Lake was close to 0 and showed a phosphorus sink. Correlation analysis showed that the migration and transformation of phosphorus was significantly affected by the reduction and dissolution of iron oxides in SWI, meanwhile attention should also be paid to the influence of organic matter mineralization on phosphorus release in sediment.
