摘要/Abstract

摘要： 摘要本文通过2011年7月26日～8月7日厦门同安湾发生的赤潮进行监视监测，对赤潮发生时水文气象、化学、生物因子进行了分析。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产生的盐度的急剧下降是此次赤潮的诱因。

Abstract: Abstract： A red tide in Tong’an bay， Xiamen Seas during July 26 to August 7 2011 was reported in this paper, and the in situ hydrological, meteorological, chemical and biological factors were analyzed. It was indicated that this red tide with the area of 105 km2 was a hybrid triphase red tide in which the red tide species include Skeletonema costatum, Akashiwo sanguinea, Chaetoceros sp.. The major causes were eutrophication, continuous high air temperature and the water body stability of neap tide, and the air pressure due to “Luotan” typhoon and sharp decline of salinity due to rainfall also contributed to this red tide
