摘    要:本文整理了2001-2019年近20年福建沿海231次赤潮事件,通过统计方法综合分析,结果表明,福建沿海赤潮的发生具有明显的时间和区域特点,赤潮主要发生在4-7月,高发期为5-6月,位置集中在宁德、福州、平潭和厦门沿海区域;主要赤潮生物种类为东海原甲藻(Prorocentrum donghaiense)、夜光藻(Noctiluca scintillans)、中肋骨条藻(Skeletonema costatum)、角毛藻(Chaetoceros sp.)和米氏凯伦藻(Karenia mikimotoi),以甲藻类赤潮为主;灾害性赤潮均为甲藻类赤潮,造成直接经济损失最多的是米氏凯伦藻赤潮。本文的研究结果可以为福建沿海赤潮的防灾、减灾工作提供一定的参考。

Abstract:There were 231 red tide events collected during the last two decades from 2001 to 2019 in Fujian coastal waters, using statistical method to comprehensive analysis the temporal and spatial distribution characteristics of the red tide in Fujian coastal waters. The result shows that the red tide displayed a distinctive spatial-temporal characteristics. The red tide occurred in April to July mainly, and the high incidence period was May to June. The red tide occurred in Ningde, Fuzhou, Pingtan and Xiamen coastal waters mainly. The primary red tide organisms were Prorocentrum donghaiense, Noctiluca sintillans, Skeletonema costatum, Chaetoceros sp. and Karenia mikimotoi. The disastrous red tide were dinoflagellate which lead to the huge economic loss.
