摘　　要：本文通过对1993-2003年的Nino3、Nino3．4区的海水表层温度(SST)和闽南-台湾浅滩渔场灯光围网作业的中上层鱼类年总产量和年平均单位产量,进行线性回归分析并经F检验,得出它们在α= 0．05的水平上回归效果显著的结论(F＞F_(α=0．05))。其中,Nino3的海水表层温度与闽南-台湾浅滩渔场灯光围网作业中上层鱼类年总产量的相关关系R=0．7225,Nino3．4区的海水表层温度与闽南-台湾浅滩渔场灯光围网作业中上层鱼类年总产量的相关关系R=0．6685;Nino3的海水表层温度与闽南-台湾浅滩渔场灯光围网作业中上层鱼类年平均单位产量的相关关系R=0．6319,Nino3．4区的海水表层温度与闽南-台湾浅滩渔场灯光围网作业中上层鱼类年平均单位产量的相关关系R=0．6541。这种关系的找出,今后可以通过美国国家海洋和大气局(NOAA)提前一年预测的NINO区海表温度数据,为闽南-台湾浅滩渔场灯光围网作业渔情预报建立简便可靠的新方法。This paper regressed the relationships among the sea surface temperature （SST） of NINO regions, the total annual catch and the average catch of pelagic fish per fishing unit by the .light purse net in Minnan - Taiwan Bank Fishing Ground in 1993 -2003. After F- test, the correlation coefficient showed significantly positive correlation in the range of confidence interval of 95% （F〉 F0.05 ）. Among them, the correlative coefficient between the SST and the total annual yield of pelagic fish is 0. 722542 in Nino3 region and 0. 668498 in Nino3.4 region, respectively. The correlative coefficient between the SST and the average catch per fishing unit is 0. 631859 in Nino3 region and 0. 654101 in Nino3.4 region, respectively. The relationship found will give us some helpful advice to establish predicted equation of fishing information based on the data of NINO region provided ahead by NOAA every year and some other related data.
