【摘要】 1999年 5月在广东省惠阳大亚湾发生一起Peridinium quinquecorne赤潮。利用光镜和电镜对赤潮生物进行形态学观察。赤潮期间 ,赤潮生物最高密度可达 11.8× 10 6L-1,随着气温骤降 ,赤潮消退。P .quin quecorne是一喜生活在富营养化的浅湾内兼具附着、浮游习性的种类 ,针对赤潮发生区域的营养盐与该种赤潮发生的关系作了探讨。更多还原

【Abstract】 A bloom of the dinoflagellate Peridinium quinquecorne Abe firstly occurred in a eutrophic shallow waters in South China Sea in May 1999. The morphology and structure of the organism were studied through LM and SEM. The highest population density(11.8×10 6 L -1 ) was in the intensively stained waters(Ya qian Bay). The bloom lasted for more than 10 days and disappeared when the temperature turned down sharply. The relationship between nutrient and occurrence of the red tide was discussed.更多还原
