摘　　要：作者在国家海洋局第三海洋研究所的陆基水池中 ,应用围隔实验技术 ,排除了水动力、盐度等环境因子的变动性的干扰 ,人工诱发甲藻赤潮 .在这个围隔实验的两个围隔体中 ,分别发生了一种裸甲藻 (Gymnodiniumsp .)和海洋原甲藻 (Prorocen tummicans)的赤潮 .在赤潮发生和发展过程中所监测到的营养盐数据表明 :有些甲藻增殖不一定需要水体中高营养盐 ;In an enclosed experimental system, which was conducted in the land based tanks in Third Institute of Oceanography, SOA, Xiamen, we induced dinoflagellate red tides artificially without the effects of disturbance of salinity and water movement. There occurred red tides of Gymnodinium sp. and Prorocentum micans respectively in two enclosures of this experiment. The nutrient data examined in the forming and development processes of the red tides showed that the multiplication some dinoflagellates species of did not reguire a higher level of nutrient concentration in water column. But nutrient supply would affect the dinoflagellate red tide scale and its dominated species. [WT5F1]
