| 摘 要： | 基于2006年6、8、10月对长江口邻近海域的大面调查资料,分析了溶解态Al的分布及季节变化,讨论了水团混合、悬浮颗粒物及浮游植物水华对溶解态铝分布的影响。结果表明,3个航次溶解态铝的水平分布规律相似,都是近岸浓度最高,随着离岸距离的增加浓度降低,6、8、10月溶解态Al的平均浓度分别为(119±77)、(109±80)和(138±73)nmol/L,统计结果表明该海域的溶解态铝具有明显的季节变化。影响溶解态铝分布的主要因素有水团混合、底沉积物的再悬浮以及浮游植物的调节作用。

| Abstract: | Three cruises were carried out in the Changjiang Estuary and its adjacent area in June,August and October of 2006.The distributions and seasonal variations of dissolved Al were presented,and the influencing factors include the water masse mixing,suspended particles and phytoplankton bloom were discussed.The distributions of dissolved aluminum were higher in the coastal area and decreased gradually from the coastal area to the central East China Sea shelf.The average concentrations of dissolved Al in June,Au... |
