摘　　要：根据引水船海洋站1960—2001年、大戢山海洋站1978—1999年、吕四海洋站1960—1990年、滩浒岛海洋站1984—2001年、嵊山海洋站1973—2001年夏季6—8月、秋季9—11月月平均表面水温资料和美国NCEP/NCAR的北半球月平均500hPa高度场、850hPa风场再分析资料,利用合成分析及相关分析方法,分析东亚夏季风对长江口海域(区)表面水温(SST)的影响。结果表明:长江口区夏季SST呈近岸高,外海低的特点。长江口区SST冷夏年,东亚夏季风较弱;暖夏年东亚夏季风较强。强夏季风年,长江口区夏季、秋季SST偏高;弱夏季风年,长江口区夏季SST偏低。This paper used the mean summer and autumn SST data at five stations in the Changjiang estuary, including Yinshuichuan （1960 - 2001 ）, Dajishan （ 1978 - 2000 ）, Lvsi （ 1960 - 1990 ）, Tanxudao （ 1984 - 2001 ）, Shengshan （ 1973 - 2001 ） ocean stations. And it also used the monthly average reanalysis data of 500hPa height and 850hPa wind fields from the NCEP / NCAR （ 1960 -- 2001 ）. By composite analysis and correlation methods, the paper analyzed the influence of East Asia summer monsoon on SST of the Changjiang estuary. The main conclusions are as follows： the summer SST in the Changjiang estuary appears high near coast and low far from coast. In cold summer SST year of Changjiang estuary, the strength of East Asia monsoon is weak, while in warm summer SST year, it is strong .In strong summer monsoon year, the summer and autumn SST of Changjiang estuary is high. In weak summer monsoon year, the summer SST of Changjiang estuary is low.
