摘　　要：根据2005年3月至2006年1月我国大型拖网加工渔船在东南太平洋的生产资料，结合海表温数据，按经纬度1°×1°的空间单位进行分析，利用Marine Explorer4．0软件作图，研究作业渔场CPUE分布与海表温的关系。结果表明，适宜作业海表温为12～15℃，月平均CPUE呈正态分布：8月最高，为11．34t／h；6～9月均超过7．00t／h，密集鱼群区域分布在34°～40°S，79°～92°W，其海表温范围为13～15℃；10月平均CPUE为6．08t／h，其表温范围为14～17℃；其余各月平均CPUE均不超过4．30t／h。CPUE与适宜海表温关系通过K—S的检验。According to the production database from March 2005 to January 2006 of Chinese trawler fishing vessels with the statistic format of 1°× 1°, the plot is drawn by the software of Marine Explorer 4.0. Correlation of fishery distribution of jack mackerel versus SST is analyzed. The suitable SST was 12 - 15 ℃, and the average CPUE by month obeys the normal distribution with the peak of 11.34 t/h in August. From June to September the monthly average CPUE was at least 7.00 t/h. The fishing ground concentrated in the area of 34°- 40° S and 79°- 92° W with SST 13 - 15℃. The average CPUE in October was just 6.08 t/h with SST 14- 17 ℃. The average CPUE of other months was less than 4.30 t/h. The relation between CPUE and suitable SST passed the K- S test.
