根据2003年~2011年中国东南太平洋智利竹筴鱼（ Trachurus murphyi）大型拖网渔捞数据和海表温度（ SST）数据，利用ArcGIS 10.0绘制渔场产量重心时空分布图，用最短距离法对中心渔场进行聚类，对智利竹筴鱼渔场月间重心变动规律及其与SST之间的关系进行分析。结果表明，随着月份的变化，中心渔场从3月开始由南逐渐向西北方向移动，到10月之后逐渐向东南方向移动。3月~6月渔场主要分布在80° W~90° W、40° S~45° S，最适宜SST为12~14℃；7月~8月渔场主要分布在80°W~90°W、35°S~40°S，SST为13~14℃；9月~10月渔场分布为85°W~95°W、30°S~35°S，SST这15~16℃；11月~12月渔场分布在90°W~95°W、30°S~40°S， SST为16~17℃；而1月~2月渔场分布在85°W~95°W、35°S~45°S，最适宜SST为16~17℃。

Based on the fishing data of Chilean jack mackerel( Trachurus murphyi)obtained by Chinese large trawling fleets in the Southeast Pacific Ocean during 2003~2011 as well as the data of sea surface temperature( SST),the main fishing ground plot was drawn by software of ArcGIS10. 0 by which we analyzed the relationship between monthly variation in fishing grounds positions of Chil-ean jack mackerel and SST. The results show that the central fishing ground moved gradually from south to northwest since March,and then removed gradually to southeast after October. The fishing grounds were mainly distributed:in the areas of 80°W~90°W,40°S~45°S with the most suitable SST of 12~14 ℃ from March to June;in the areas of 80°W~90°W,35°S~40°S with the most suit-able SST of 13~14℃ from July to August;in the areas of 85°W~95°W,30°S~35°S with the most suitable SST of 15~16℃ from September and October;in the areas of 90°W~95°W,30°S~40°S with the most suitable SST of 16~17 ℃ from November to De-cember;in the areas of 85°W~95°W,35°S~45°S with the most suitable SST of 16~17 ℃ from January to February.
