摘　　要：1999年 3月至 2 0 0 0年 6月广东大亚湾澳头先后发生拟菱形藻赤潮、日本星杆藻赤潮、原变型翼根管藻赤潮、五角多甲藻赤潮、脆根管藻赤潮。本文分析了赤潮期间TOC浓度的动态变化过程 ,并分析了TOC浓度在赤潮形成和消亡过程中与赤潮生物数量之间的变化关系。研究结果显示 :TOC浓度的大幅度波动与赤潮的生消密切相关。不同藻类赤潮过程TOC浓度的变化趋势不完全相同。Concentrations of total organic carbon (TOC) in the samples collected were detemined during the investigation of the phytoplankton of Daya Bay in Aotou, Guangdong province. From Mar. 1999 to Jun. 2000, six red tides events have been occurred successively in Daya Bay. The red tide was causative Pseudo-nitzschia sp., Asterionella japonica, Rhizosolenia alata f. genuine, Peridinium quinquecorne and Rhizosolenia fragillissima. The variations of TOC during these red tide and the relationship between the variation of TOC and the quantity of algale were studied. The showed that: The rapid variations of TOC was relative the vanishing of algale red tide. The variations of TOC during differnt algal red tide are not same.
