| 摘 要： | 对13个河口站位的沉积物以及莱州湾两个站位的柱状沉积物中的磷的三种基本结合态进行了测定。结果表明：河口沉积物中总磷量与河流污染程度有关。磷的主要存在形态是以磷灰石结合态磷（PAI）存在的无机结合态磷（PIN）。莱州湾的柱状沉积物磷含量以及存在形态在离岸近和表层站位受到河流一定程度的影响，而在深层和离岸远的站位受河流影响的程度降低，各种形态的磷含量已趋于平衡。

| Abstract: | This paper presents the results of a prelimitary study on the three basic formsof phosphorus in the sediments from the thirteen stations at several river estuaries andphosporus in the column sediments at several river estuaries and phosphorus in the column sediments from two stations in the Laizhou Bay.The results indicate that the total content of phosphorus in the sediment from eachstudied river estuary is closely related to the degree of pollution in the river. The existing form of phosphorus is mainly PAI which belongs to the inorganic PIA. The contentand the existing form of phosphorus in the column sediments from the Laizhou Bay are,to a certain degree, affected by the environment of the river. The closer the station is tothe river bank and river surface, the fewer the influence is, and Vice Verea. In the sediments from the deep river far from the river bank, the content of phosphorus in forms ofphosphorus tends to be in balance. |
