The results show that the contents and distributions of mercury in Jiaozhou Bay were affected by coastal runoff and phytoplankton bloom The linear relationship between organic mercurv and the COD and the exponential relationship between inorganic mercury and chl-a implied that marine phytoplankton could absorpt mercury in sea water and played an important role in controling the speciations of mercury in the Bay.

测定结果表明，胶州湾中汞含量和分布规律与浮游植物的盛衰和陆地迳流有关。有机汞和COD之间存在着线性关系，溶解无机汞含量随叶绿素a含量增加呈指数下降，表明浮游植物对汞的富集及其在海水中形态的转化起着十分重要的作用。

They also showed that large Cladocera size is more important than their number for efficient phytoplankton control and when cladocerans are large enough, they can considerably restrain phytoplankton growth, including bloom-forming cyanobacteria, even when submerged vegetation is not restored.

同样，它们也显示了大型枝角类的体型相对于它们的数量就对浮游植物的有效控制上意义更大。当枝角类足够大时，它们能够限制浮游植物的生长，包括蓝藻的爆发，即便当沉水植被没有及时恢复。

In the CO_2 source area, phytoplankton abundance was low and zooplankton mainly belonged to true estuary and estuary marine communities; while in the CO_2 sink area, phytoplankton was high and zooplankton mainly belonged to euryhaline marine communities.

在枯水季节，长江口海域由低盐区大气二氧化碳的强源逐渐过渡到高盐区的弱汇，咸淡水的混合在一定程度上决定了该区域碳源汇的格局；二氧化碳源区，浮游植物的丰度低，浮游动物主要是纯河口类群和河口性海洋类群，而汇区，浮游植物的丰度高，浮游动物主要是广盐性海洋类群。
