厦门市潘涂虾池一次简单裸甲藻（Gymnodinium simplex Lohmann）赤潮的调查

对厦门市潘涂虾场一口虾池1995年4月发生的一起简单裸甲藻赤潮进行跟踪调查，报道赤潮期间虾池水环境因子、浮游植物生物量的变化特征以及浮游植物的种类更替。调查显示，赤潮发生前浮游动物大量繁殖，快速消耗浮游植物进而引起池内无机营养盐（特别是活性磷酸盐）的积累是本次赤潮发生的重要原因。赤潮发生期间，赤潮生物的暴发性增殖在抑制多数藻类（主要是硅藻）的同时，也促进了一些裸藻类、甲藻类和蓝藻类的生长繁殖。

A Survey on a Gymnodinium simplex Lohmann red tide in a shrimp pond in Pantu, Xiamen

A red tide of Gymnodinium simplex Lohmann in a shrimp pond in Pantu shrimp cultivation area, Xiamen, was investigated. The variation of the ecological factors of water and the biomass of phytoplankton in shrimp pond, and the species succession of phytoplankton during the red tide were reported. The results suggested that the accumulation of nutrients, especially reactive phosphate, caused by the mass growth of zooplankton consuming phytoplankton rapidly, was the important reason for this red tide. The rapid multiplication of red tide species during red tide restrained the majority of alga, mostly the diatom, while promoting the growth of some species belonging to Euglenophyta, Pyrrophyta and Cyanophyta.
