2010年3月在厦门湾采集表层沉积物，应用改进的化学试剂连续分级浸取法(SEDEX)法对其中的弱吸附态磷(Ads-P)、铁结合态磷(Fe-P)、自生磷灰石及钙结合态磷(Ca-P)、碎屑态磷(De-P)和有机态磷(OP)的含量进行了分析测定，结合沉积物的环境参数，讨论了各种形态磷的地球化学行为。Ads-P、Fe-P、Ca-P、De-P、OP和总磷(TP)平均含量分别为9.80μg?g-1、148.69μg?g-1、14.07μg?g-1、136.89μg?g-1、91.97μg?g-1和401.41μg?g-1。研究表明，沉积物中的TP受陆源输入影响较小；Ads-P和Ca-P含量主要源于海区内部生物地球化学过程；De-P、OP和Fe-P主要受陆源输入影响；Ca-P、De-P和OP与重金属(Cu、Pb、Cd和As)具有化学耦合作用，在沉积过程中，可能具有相似地球化学行为。

Surface sediments were collected from the Xiamen Gulf in March 2010. The sediments were analyzed with modified SEDEX (sequential extraction and separation analysis method) to obtain Ads-P (absorbed phosphorus), Fe-P (iron-bound phosphorus), Ca-P (phosphate bound onto CaCO3), De-P (detritus phosphorus), and OP (organic phosphorus). Along with environmental parameters of sediments, the geochemistry characters of phosphorus were discussed.The mean contents of Ads-P, Fe-P, De-P, Ca-P, OP, and TP (total phosphorus) were 9.80, 48.69, 14.07, 136.89, 91.97, and 401.41μg?g-1, respectively. The results showed that TP was weakly influenced by terrestrial input, and De-P, OP and Fe-P were mainly influenced by terrestrial input. Ads-P and Ca-P were mainly from biogeochemical processes of the sea area. Ca-P, De-P and OP with heavy metals (Cu, Pb, Cd, and As) possessed chemical coupling, and might have similar geochemical behavior in the deposition process.
