摘　　要：根据南沙群岛海域船舶报的表层水温和波浪资料，分析了ElMino事件对该海域上述水文要素的影响。结果表明：（1）在该海域与赤道东太平洋，表层水温变化是同位相，而与赤道西太平洋呈反位相;（2）在ElNino年，南沙群岛海域海况恶劣，大浪频率增加；更以ElNino的次年为甚。文中对产生以上现象的原因作了初步探讨。Based on the SST and wave data observed by vessels passing through the Nansha Islands waters, the El Nino event's effects on hydrological factors in the above waters are analyzed. The results are as follows: (1) SST of the Nansha Islands waters varies with that of the Eastern Equatorial Pacific Ocean in synchronous phase, but varies with that of the Western Equatorial Pacific Ocean in opposite phase; (2)The sea is rough and the frequency of rough sea increases in the Nansha Islands waters in the year of El Nino, especially in the next year of the El Nino year. The reasons causing above phenomena are discussed.
