【摘要】：对温州近岸海域2007~2016年间发生的赤潮灾害进行综合分析,结果表明:(1)时间分布上,赤潮主要发生在4~9月,高发期为5~6月,平均每次赤潮持续时间为8.6天;(2)空间分布上,赤潮主要发生在南麂海域、苍南海域和洞头海域,其中发生在南麂海域次数最多,占赤潮发生总数的46.0%;(3)引发赤潮的生物有10种,其中硅藻门3种,甲藻门5种,着色鞭毛藻门和原生动物门各1种,引发赤潮次数最多的是东海原甲藻(Prorocentrum donghaiense),其次为米氏凯伦藻(Karenia mikimotoi),引发赤潮的生物种类具有演替规律,不断有新的种类引发赤潮;(4)引发有毒赤潮的藻种主要为米氏凯伦藻(Karenia mikimotoi),通过对近10年温州近岸海域赤潮的全面分析,为温州赤潮的防灾减灾和赤潮预警工作提供科学合理的依据。
[Abstract]:A comprehensive analysis of the red tide disaster occurred in the coastal waters of Wenzhou from 2007 to 2016 shows that the red tide occurred mainly from 4 to September and from 5 to June in the time distribution of the red tide. The mean duration of each red tide was 8.6 days. (2) in spatial distribution, red tide mainly occurred in Nanji sea area, Cangnan sea area and Dongtou sea area. (3) there are 10 species of red tide, including 3 species of diatoms, 5 species of Pyrolima, 1 species of flagellata and 1 species of protozoa. The most frequent red tide was Prorocentrum donghaiensei in the East China Sea, followed by Karenia mikimotoi. The species of organisms causing red tide have succession law, and new species cause red tide. (4) the main species causing the toxic red tide is Karenia mikimotoi. The red tide in the coastal waters of Wenzhou has been comprehensively analyzed in the last 10 years. It provides a scientific and reasonable basis for the prevention and mitigation of red tide and early warning of red tide in Wenzhou.

【正文快照】： 引言赤潮是我国沿海地区主要海洋生态灾害之一,也是当今世界海洋的一大灾害,它的发生对海洋水体生态环境、水产养殖及滨海旅游业等构成了危害,甚至有些赤潮生物所分泌的毒素能随着食物链进入人体,从而危及人类的健康和安全[1]。近十几年来,随着全球沿海地区经济的迅猛发展和城
