摘　　要：对 1995年、1999年发生在辽东湾的夜光藻赤潮及 1998年发生的叉状角藻赤潮的成因进行了初步分析和研究。结果表明 :夜光藻与叉状角藻都具有鞭毛 ,夜光藻完全异养 ,叉状角藻则以自养为主 ,同时兼有异养。同样条件下这两种甲藻由于其运动特性 ,可以选择光照适宜和营养丰富的水层 ,更有利于生长繁殖 ,比其他硅藻类更易形成赤潮。同时外部的环境条件 ,包括生物的。Based on the monitoring and investigation of three times red tides caused by Noctiluca scientillans and Ceratium furca in Liaodong Wan Bay,in this paper the characters of red tides organisms and the relationship between red tides and weather conditions are described and analyzed.Both Noctiluca scientillans and Ceratium furca belong to dinoflagellate. Noctiluca scientillans is a heterotrophic organism, Ceratium furca has the two characters of autotrophic and heterotrophic organism.These two red tides organisms all have flagellum.The motility allows them have the option of seeking deeper nutrient rich waters.In the same conditions,the red tide is more often caused by dinoflagellate than by diatom.The characters of Noctiluca scientillans and Ceratium furca ,the effects of the environmental conditions of the seawater and the weather conditions are the imperative factors for red tide formation.
