摘要

摘要: 闽浙沿岸海域是我国赤潮多发区之一,为研究浮游植物对铝的清除提供了良好的场所。于2007年5月和2008年5月对该区域溶解态铝的分布进行了调查分析,讨论了水团混合、悬浮颗粒物以及浮游植物水华对溶解态铝分布的影响,结果表明,溶解态铝的分布表现为近岸高、远岸低、表层浓度低于底层的特点,统计分析显示两年观测的结果无显著差异。影响溶解态铝分布的因素主要有水团混合和底沉积物的再悬浮,此外浮游植物水华对溶解态铝也具有一定的清除作用。

Abstract: The coastal area of Zhejiang and Fujian is one of the red tide-prone areas in China which is a good place for the study of the scavenging of aluminum by the phytoplankton from seawater. Two cruises were carried out in the coastal area of Zhejiang and Fujian in May 2007 and May 2008, respectively. The distribution of dissolved aluminum concentration is investigated, and the influencing factors including the water mass mixing, suspended particles and phytoplankton bloom are discussed. The distribution of dissolved aluminum concentration showed higher in the near coastal area and the near-bottom layer, and there is no significant interannual variation through statistical analysis. The water mass mixing and the sediment re-suspension are the main influencing factors of the distribution of dissolved aluminum concentration. In addition, the phytoplankton bloom also has a scavenging effect on the dissolved aluminum concentration.
