我国海域赤潮发生与海温及厄尔尼诺的相关分析

THE RED TIDE EVENTS IN THE CHINA SEA AND THE RELATIONSHIP WITH THE TEMPERATURE AND EL NINO

分析2000年以来我国海域赤潮发生次数和面积,以及期间与厄尔尼诺指数关系,分析认为①海域表温对我国4个海域赤潮发生有较显著影响。②2000～2007年4个海域发生的赤潮次数:东海>渤海>南海>黄海;2000～2007年4个海域赤潮发生面积:东海>渤海>黄海>南海。③1986～2007年厄尔尼诺对赤潮发生次数有一定的影响,4个海域赤潮发生次数与厄尔尼诺的相关程度不同:东海>南海>渤海>黄海,其中1999年后厄尔尼诺对中国近海赤潮发生次数具有显著影响。④1977～2007年发生的10次厄尔尼诺事件对厄尔尼诺年的次年我国海域赤潮发生的次数有比较显著的影响。

In the paper, the number and area of red tide events and E1 nino3.4 index since 2000 year were analysed. The conclusions are as following： ① The red tide events in the China Sea have been influenced by the sea surfer temperature. ② The number of red tide events in China Sea is that： East China Sea〉 Bohai Sea 〉 South China Sea 〉Yellow Sea, and area of red tide events in China Sea is that： East China Sea〉Bohai Sea〉Yellow Sea〉 South China Sea. ③ E1 nino has evidently influence to the number of red tide events in China Sea from 1999-2007, and it is different in different Sea： East China〉South China Sea〉Bohal Sea〉Yellow Sea. ④ The influence of the E1 nino on the red tide events is evident at ten E1 ninos from 1977 to 2007.
