摘　　要：利用2000—2008年中国鱿钓船在西南大西洋阿根廷滑柔鱼(Illex argentinus)的生产数据与海洋卫星反演资料,分析了近9年西南大西洋阿根廷滑柔鱼资源丰度的变化及其与主要的生态因子(海表温度和叶绿素a)的关系。结果表明:该鱼种的年平均资源丰度在近9年出现了较大变化,以2004年为转折点,之前呈下降的趋势,至2004年降至最低,2005年后逐年上升;在该时期,这两个生态因子与该鱼种资源丰度的变动存在一定的关系:2000—2003年该海域年均海表温度波动较大,但资源丰度较平稳,两者的变动之间未发现存在明显的关系,2004—2008年年均海表温度和资源丰度的变动表现为显著的负相关;2000—2004年年均叶绿素a与资源丰度的变动之间未呈现明显的相关性,2005—2008年年均叶绿素a与资源丰度表现为较强的正相关。Based on the 2000-2008 squid jigger （Illex argentinus） catch data of C hinese vessels in Southwest Atlantic Ocean and the related environmental information deriv ed from satellites,this paper analyzed the recent 9 years change of I.argent inus resource abundance and its relations to the main ecological factors sea s urface temperature （SST） and chlorophyll-a concentration （Chl-a） in the Ocean.In the recent 9 years,the mean annual I.argentinus resource abundance in the Oce an changed greatly,with a turning point in 2004,i.e.,decreased before 2004 an d increased after 2004.In the nine years from 2000 to 2008,the SST and Chl-a in the Ocean had definite correlations with the changes of the I.argent inus resource abundance.In 2000-2003,the annual SST had a larger fluctuation while the mean annual I.argentinus resource abundance was relatively const ant,no obvious correlations between them.From 2004 to 2008,there existed a ne gative correlation between the resource abundance and SST.In 2000-2004,the I .argentinus resource abundance had no obvious correlation with the Chl-a .From 2005 to 2008,a positive correlation was observed between the resource abundance and the Chl-a.
