摘要: 探讨了甲藻赤潮与浮游植物演替的关系。多次国隔生态系实验结果表明,在水体相对稳定的生态系中,富营养后总是先发生硅藻的水华或赤潮。随后浮游植物会演替成占优势的甲藻,甚至形成甲藻赤潮。维生素B12的异常增多可能加速这种演替的进程。但这种稳定水体若受到扰动,将干扰演替,使硅藻水华持续不断地发展,阻碍甲藻形成优势。这可以防止甲藻赤潮的生成。

Abstract: The relationship between phytoplankton succession and dinoflagellate red tide is discussed in this paper. Aseries of marine enclosed experiments in different seasons and years show that in an ecosystem of relatively stable water body enriched with nutrients, a dinoflagellate red tide always appeares following the diatom bloom or its red tide in phytoplankton succession. The abnormal increase of vitamin B12 may promote the succession processes. The succession in stable water column could be interfered by stirring. Under this condition, the diatom bloom would develop continuously. block the formation of dinoflagellate dominance and prevent its red tide formation. The experimental results have practical meaning as they may be used to predict possible dinoflagellate red tide occurrence in enclosed or semi-enclosed waters.
