摘要: 通过晋江感潮河段表层沉积物中磷的总量测定、形态分级提取,探讨了该区域磷的分布、赋存形态特征以及环境意义.14个采样点表层沉积物中总磷的含量范围为459.6—986.2 μg·g-1.该地区与国内典型的河口感潮河段比较,总磷处于相对较高水平.空间分布特征总体表现为晋江感潮河段的中游>下游>上游.总磷中87.4%以无机磷形式存在,钙磷、闭蓄态磷、有机结合态磷和铁铝结合态磷是沉积物中磷的主要赋存形态,分别占总磷的31.2%、28.1%、12.6%和26.6%.沉积物中潜在生物有效磷(BAP)含量为90.5—424.94 μg·g-1,平均含量为269 μg·g-1.钙磷的分布受到水体中盐度变化的影响,自晋江感潮河段向泉州湾外海方向呈增大趋势;铁铝结合态磷则相反,分布朝泉州湾方向逐步递减.

Abstract: In this paper, the total phosphorus in tidal-beach surface sediments of Jinjiang River was determined,and the phosphorus speciation was further analysed. On the basis of this, the distribution, speciation characteristics, and the environmental impact of phosphorus in this area were discussed. The results showed that the content of total phosphorus ranged in 459.6—986.2 μg·g-1 among the 14 sampling points along Jinjiang tidal beach. Comparing with other typical domestic tidal beaches, the content of total phosphorus is relatively high in this area. The general spacial distribution is middle stream>down stream>up stream.The results of phosphorus speciation analysis indicated that inorganic phosphorus accounted for 87.4% of TP, and the main forms of phosphorus were calcium-bound phosphorus (Ca-P), residual inorganic phosphorus (Re-P), organic phosphorus (OP), and Al and Fe-bound phosphorus ((Al+Fe)-P), which accounted for 31.2%, 28.1%, 12.6% and 26.6%, respectively.The content of potential bio-available phosphorus(BAP) in sediments ranged in 90.5—424.94 μg·g-1, the average content is 269 μg·g-1.The distribution of calcium-bound phosphorus(Ca-P) was influnced by the salinity of water,its content obviously rises from Jinjiang tidal beach towards open sea in Quanzhou bay;but Al and Fe-bound phosphorus((Al+Fe)-P) is opposite, its content decreased gradually towards Quanzhou bay.
