摘要
厄尔尼诺现象是一种对世界渔业有重要影响的气候事件,它的形成,使得海洋气候、水温、海流等因子也相应发生了不同的变化。本文对1980-2009年的Nino3.4区的海表温度(SST)和广西海洋捕捞产量的增长率进行了线性回归并经F检验分析,得出了它们在α=0.05的水平上回归效果显著的结论(F>Fα=0.05),且随着厄尔尼诺强度的增强、持续时间的增长,广西海洋捕捞产量的增长率也随之增大。因此,可将Nino3.4区的海表温度作为预测广西海洋捕捞产量的一个重要指标。
El Nino is a major climatic event significantly affecting the world fishery.Its formation makes marine climate,water temperature,ocean current and other factors also changed correspondingly,it also has certain influence on the output of marine fishing in Guangxi.The linear relationship between the sea surface temperature（SST） of Nino 3.4 regions and the growth rate of the output of marine fishing in Guangxi area in 1980-2009 is representative.The result showed significantly positive correlation in the range of confidence interval of 95%（FFα=0.05） by F-test,and with the more enhancement of the El Nino intensity,the longer duration,the growth rate of the output of marine fishing also increased clearly.According to the correlation,the prediction of marine capture production can be made in advance by using the SST of Nino 3.4 regions.
