摘要
本文评述了１９９２年秋冬季在厦门进行的一次海洋围隔生态系实验的结果。实验重现了围隔水体连续富营养引发了甲藻赤潮的现象。间歇性的供给无机氮，不会影响浮游植物演替的顺序，但会导致甲藻赤潮出现时间长短和优势种的差异。实验结果还表明，演替过程对甲藻赤潮的形成起着重要的作用。而不同种属甲藻的生活习性和它们的自养能力使它们的生存能力存在差异。这是形成甲藻赤潮优势种的一个主要因素。甲藻赤潮的发生并不完全依靠水体中营养盐浓度的大小。
he results of a marine enclosed ecosystems experiment in Xiamen in fall and winter of1992 were reported.The results showed again that an enclosed water column could induce adinoflagellate red tide through a continual nutrient enrichment.Intermitted inorganic nitro-gen supply did not affect the order of phytoplankton succession,but affect the duration of di-noflagellate red tide and its’dominated species.The results also showed that the successionwas important in forming a dinoflagellate red tide. Different species of dinoflagellates has dif-ferent subsistence capability conducted by their behavior and autotrophic capability influen-cing the dominated species to be formed.The forming of dinoflagellate red tide was not nec-cessary relative to the nutrient concentration in water column.
