文章利用海洋再分析产品及卫星遥感资料等分析了赤道东印度洋与孟加拉湾经向盐交换的季节变化特征，估算了孟加拉湾湾口6°N 断面的年均淡水输运量。盐通量计算结果表明孟加拉湾与赤道东印度洋的盐交换过程主要由海流控制，湾口东西两侧过程基本相反。西南季风期(东北季风期)西侧为向北(南)的盐通量，东侧为向南(北)的盐通量。湾口经向淡水输运量的分析表明，断面上层在4~10月湾内向湾外输运淡水；在11月~次年3月则相反。年均经向淡水输运量的分析表明，在整个深度层次上由孟加拉湾向赤道东印度洋输运淡水，断面年均淡水输运量为1.0×105m3·s-1。

Based on the simple ocean data assimilation (SODA) reanalysis and satellite observations, we analyzed the seasonal variation of the meridional salt exchange between the Bay of Bengal (BOB) and the equatorial eastern Indian Ocean (EEIO). We estimated the annual-mean freshwater transport along the 6°N section at the mouth of the BOB. Results showed that the salt exchange between BOB and EEIO is dominated by the currents, and its direction is almost opposite between the east and west sides at the bay mouth. During the southwest monsoon (northeast monsoon), the salt flux is northward (southward) in the west while it is southward (northward) in the east of the bay mouth. Furthermore, the freshwater flows out of (into) the bay during April to October (November to the following March). The freshwater transport from the BOB to the EEIO happens in the whole depth. The annual-mean freshwater transport is 1.0×105m3·s-1.
