| 摘 要： | 2010年中国科学院东北印度洋科学考察期间,对孟加拉湾水域初级生产力展开了研究.孟加拉湾表层水体的水温较高,盐度变化范围较大,且上层水体营养盐含量较低,在真光层底部营养盐浓度突然增加.表层叶绿素a浓度较低(＜0.1 mg/m3),叶绿素a最大值常出现在75 m水深处,上层水体浮游植物的生长受氮限制明显.表层潜在初级生产力低于0.2mgcm-3h-1,且初级生产速率在50-75 m出现最大值.水柱中初级生产力变化范围为199-367 mgCm-2d-1,高值出现在88°-89°(E)附近.浮游植物固碳的主要贡献者是微微型浮游生物(＜3 μm),其次是小型浮游生物(＞20 μm)和微型浮游生物(3-20 μm),但表层与75 m水深处固碳浮游植物的结构有一定差异.将孟加拉湾与阿拉伯海初级生产力进行对比,孟加拉湾水体初级生产力显著低于阿拉伯海,且初级生产力的影响因素有着显著的差异.
