| 摘 要： | 以地理环境独特的上海滨岸带为研究对象，根据对冬季潮滩悬浮层、表层沉积物的研究，初步探讨了潮滩不同粒径沉积物中各无机形态磷的地球化学特征：DP、(Fe Al)-P在靠近排污口的采样点含量高，同时随粒径变化复杂；沉积物中（Fe Al)-P含量随粒径变大而升高，悬浮层沉积物中（Fe Al)-P更能指示环境的污染状况；一般细粉砂质沉积物中Ca-P含量高。

| Abstract: | Based on the analysis of tidal suspended and surface sediments taken from Shanghai coastal zone in winter, where there is characteristic by the special natural geographical environment as a study subject, this paper presents the geochemical feature of inorganic phosphorous species in tidal sediments of different grain sizes. It shows that the content of DP with (Fe+Al) P is higher in some sampling sites near sewage discharge outlets, and its range is complex with grain size variation. The content of (Fe+Al)-P increases with grain size increasing, while (Fe+Al) P concentration levels in suspended sediments can be used as one of indications for coastal environmental contamination. Generally the content of Ca P is higher in fine silt sediments. |
