摘　　要：阿根廷滑柔鱼（Illex argentinus）是西南大西洋重要的经济性头足类,也是中国大陆鱿钓渔业重要的捕捞对象,掌握其渔场时空分布特性及其与海洋环境之间的关系是合理开发、有效管理资源的基础.本文根据2000～2010年中国大陆鱿钓渔业在西南大西洋39°～51°S、57°～67°W海域的生产统计数据,对西南大西洋阿根廷滑柔鱼中心渔场时空分布及与海洋表层温度（sea surface temperature,SST）的关系进行了研究.结果表明,1～5月间,阿根廷滑柔鱼产量及作业次数在纬度方向由南向北逐渐递增,经度方向上由西向东逐渐递增.不同年份间,阿根廷滑柔鱼渔场重心纬度方向上存在显著性差异,而经度方向分布则不存在显著性差异.相关性分析表明,1～5月阿根廷滑柔鱼渔场重心纬度、经度的变化与SST之间存在显著相关性,并且渔场重心均随着SST的升高呈现向南和向西移动的趋势.The short-fin squid Illex argentinus is one of the most important economic cephalopod resources in the Southwest Atlantic and plays a crucial role in the marine ecosystem.It is also one of the most important cephalopod target species for Chinese jigging fisheries.To understand the spatial and temporal variations in the distribution of fishing grounds and the influence of oceanography is critical for stock assessment and management.Based on the fishery data of I.argentines in the Southwest Atlantic in the waters of 39° to 51°S,57°to 67°W from 2000 to 2010 of Chinese jigging fisheries,the spatial and temporal variations in the distribution of fishing grounds and its relationship between sea surface temperature （SST） were studied.The results indicated that the yield and the catch number of I.argentines moved from south to north in latitude and from west to east in longitude from January to May from 2000 to 2010.The analysis of variance （ANOVA） showed that there were significant differences in the latitude distribution but no significant difference was found in the longitude distribution of the center of fishing gravity in different years.The correlation analysis showed that there were significant associations between the spatial distribution of the center of fishing gravity and SST,and both latitude and longitude increased with the increase of SST.
