摘　　要：本文测定了在厦门湾上屿附近海域定点站（“上屿”站）６个航次所采集悬浮颗粒物中Ｆｅ、Ｍｎ、Ａｌ、Ｔｉ、Ｂａ和Ｃａ ６种金属元素的含量，并结合其他相关要素，探讨了该海域悬浮颗粒物的化学组成及其生物地球化学特性。对悬浮颗粒物中Ｆｅ、Ｍｎ、Ａｌ、Ｔｉ、Ｂａ和 Ｃａ等元素的垂直分布与时间变异研究发现，它们多数与悬浮颗粒物关系密切，沉积物再悬浮作用是控制水体尤其是底层水悬浮颗粒物时空变化的主要因素。与厦门西港和九龙江口相比，上屿海域属于厦门湾海区，中受陆源输入影响较小的海域。The contents of Fe, Mn, Al, Ti, Ba and Ca in suspended particulate matter were deter mined at Station“Shangyu” in Xiamen Bay during six cruises in 1996. The spatial and tem poral variations of these elements in suspended particulate matter were studied along with other related chemical and biological parameters. Most of them are correlated with TSM. The results suggest that TSM is mainly influenced by sediment resuspension, especially in bottom waters. As compared to Western Xiamen Harbour and Jiulongjiang Estuary, sea area around Shangyu Island is influenced less by the terrigenous input.
