摘　　要：通过监视监测2011年7月26日-8月7日发生在厦门同安湾的赤潮,对赤潮发生时的水文气象、化学、生物因子等进行分析。结果表明,本次赤潮为三相混合型赤潮,赤潮生物为中肋骨条藻(Skeletonema costatum)、血红哈卡藻(Akashiwo sanguinea)和角毛藻(Chaetoceros sp.),赤潮最大面积为105km2。水体的富营养化、持续的高温天气和小潮期水体的相对稳定是本次赤潮发生的基本条件,"洛坦"台风的气压影响以及降雨导致的盐度急剧下降是此次赤潮的诱因。A red tide in Tong＇an Bay of Xiamen Seas during July 26th to August 7th in 2011 was reported in this paper. Hydrological meteorological, chemistry and biological factors were analyzed in the occurrence of red tide. The results showed that this red tide with the area of 105 km2 was a hybrid triphase red tide, and the red tide species included Skeletonema costatum, Akashiwo sanguinea, Chaetoceros sp. The basic conditions of this tide were eutrophication, continuous high air temperature and the stable water body of neap tide, the air pressure due to ＂Luotan＂ typhoon and sharp decline of salinity due to rainfall also contributed to this red tide.
