摘要
对2001年7月至2002年7月间采集的柘林湾水域痕量元素溶解铁(Fe)的含量进行详细的周年调查.结果表明,调查期间柘林湾水域Fe含量的周年平均值为0.165mg/L,高于国内其他河口或海湾,柘林湾所在饶平地区有铁矿可能是Fe含量高的主要原因.柘林湾Fe的平面分布表现为湾外的含量高于湾内的规律,这与沉积物再悬浮有很大关系.本年度Fe含量高于上一年度与浮游植物对Fe的吸收减少以及降雨等气候条件有关.
Water samples were collected in July 2001 and July 2002 in Zhelin Bay. The content of dissolved iron（Fe） in samples was analyzed. The results indicated that the annual average of Fe（0.165 mg/L） was much higher than those other estuaries in China. Irons are located near Zhelin Bay. Dissolved iron in Huanggang River and outside of the bay was higher than that inside of the bay, which might be affected by resuspending of sediments. The content of total suspended materials （TSM） outside of the bay was also higher than inside of the bay. The rainfall and the lower phytoplankton density consumed the less absorbed amount of iron, so the content of iron this year maintained is higher than the content of last year.
