摘　　要：本文简要地介绍了厦门西港表层沉积物中各形态的磷:总磷(TP)、有机磷(OP)、无机磷(IP)、水可溶解磷[P(sol)]、铁铝结合态磷[P(Al+Fe)]和钙结合态磷[P(Ca)]的含量与分布。结果表明,沉积物中TP的质量分数为(473～738)×10^(-6),平均值为560×10^(-6);TP中主要是IP,IP/TP值为60%,其他形态磷与总磷的比值是:P(sol)为1.5%,P(Al+Fe)为14%,P(Ca)为45%,OP为40%。Phosphorus in Western Xiamen Harbour surface sediments is differentited into total phosphorus (TP), organic phosphorus(OP). inorganic phosphorus(IP), loosely bound phosphorus P(sol), iron-and aluminum-bound phosphorus P(Fe+Al), and calcium-bound phosphorus P(Ca), and their special distribution is studied. The results show that the TP content in Western Xiamen Harbour ranges from 473.3×10^(-6)～737.8×10^(-6), with a mean of 560.1×10^(-6), and ratio of IP/TP, P(sol)/TP, P(Fe+Al)/TP, P(Ca)/TP and OP/TP is 60%, 1.5%, 14%, 45% and 40% respectively.Positive linear correlation coefficients are found between P(Ca) and IP, P(Ca) and TP, IP and TP, and a negative linear correlation coefficient between OP and P(Fe+Al).
