摘要

摘要:
以长江口及邻近海域为研究区域，采用改进后的SEDEX法对沉积物中各形态磷的含量进行了分析，并通过模拟实验探讨了沉积物再悬浮对上覆水体磷酸盐浓度的影响。结果表明：碎屑磷（De-P）是沉积物磷的主要赋存形态，占总磷（TP）的50%以上；其次是可提取态有机磷（Or-P）和非活性有机磷（Re-P）；生物可利用磷（BAP）占总磷的比例约为21%，可提取态有机磷（Or-P）是生物可利用磷（BAP）的主要存在形态。沉积物再悬浮时，水体磷酸盐的浓度显著升高，说明沉积物再悬浮会引起沉积物中磷的释放；水体磷酸盐浓度升高主要源于沉积物中磷的释放，而间隙水的贡献较低。沉积物发生再悬浮时，厌氧条件相对于好氧条件，更有利于沉积物磷的释放。

Abstract:
Two core sediment were collected in the Changjiang Estuary and its adjacent area as study areas. The SEDEX method was applied to determined the forms of phosphorus in the sediments. Effects of sediment resuspension on the phosphate in the water column was studied. The results indicated that Detrital P was the highest form, which accounted for above 50% of TP. The contents of organic P and refractory P were also higher than other forms. Bioavailable P was accounted for 21% of TP. Organic P was the major part of bioavailable P. The concentrations of phosphate in overlying water was significantly higher when sediment resuspension occurred. It shows that sediment resuspension can cause the phosphourus in sediment to release. The increase of phosphate concentration in water mainly comes from the release of phosphorus in sediments. And the contribution of phosphate interstitial water is less than sediments. In addition, It is more favorable to the release of phosphorus in sediment resuspension in the anaerobic condition than that in the aerobic condition.
