摘　　要：分析1981—2011年东海海域赤潮发生次数、赤潮生物种类数以及与El Ni?o关系,结果表明:东海的赤潮发生以2000年为界可划分为2个阶段,1981—2000年为第一阶段(初级阶段),赤潮年均8次,赤潮生物种数年均4种,总体处于发生频次较低水平;2001—2011年为第二阶段(高发阶段),赤潮发生的频次是第一阶段的6.4倍,年均引起赤潮生物种数是第一阶段的2.8倍;El Ni?o次年东海赤潮生物种类数相对于El Ni?o年平均增加6.6%,赤潮生物种类数平均增加56.6%,对El Ni?o第三年影响小于第二年。El Ni?o年Ni?o 3.4指数与次年赤潮生物的种类数变化率相关系数为0.70,为中等相关水平,均高于El Ni?o当年和第三年,表明El Ni?o将显著影响次年的赤潮生物种类数量。The relationships between water temperature,the records of red tide and red tide creatures in the East China Sea with El Nino phenomenon were analyzed from1981to2011.The results show that the occurrence of red tide in the East China Sea could be divided into2stages.The primary stage was from1981to2000.The average annual red tide occurred8times,and the average species of red tide creature was4.The second phase was from2001to2011.The frequency of occurrence of red tide in this phase was6.4times than the first stage,and the average annual number of red tide species was2.8times than the first stage.The records of red tide in the next year of El Nino event increased by6.6%compared the year of El Nino event in the East China Sea,and the number of red tide species increased by56.6%.Effect of El Nino on the species of red tide creature in the third year of El Nino event was less than second year of El Nino event.The correlation coefficient between Nino3.4index in El Nino year and the change rate of species of red tide creature in the next year of El Nino event was0.70.It suggested that El Nino event significantly impacted on the species of red tide creature in the next year of El Nino event.
