Marine plankton are faced with novel challenges associated with environmental changes such as ocean acidification, warming, and eutrophication. However, data on the effects of simultaneous environmental changes on complex natural communities in coastal ecosystems are relatively limited. Here we made a systematic analysis of biological and environmental parameters in the Bohai Sea over the past three years to suggest that plankton communities responded differently to current changing coastal environments, with the increase of phytoplankton and the decrease of zooplankton. These different changes of phyto- and zooplankton potentially resulted from the fact that both the effect of acidification as a result of pH decline and the effect of warming as a consequence of increasing temperature favored phytoplankton over zooplankton at present. Furthermore, water eutrophication and salinity as well as heavy metals Hg, Zn, and As had more or less diverse consequences for the dynamics of phytoplankton and zooplankton. Differently, with ongoing climate change, we also revealed that both phytoplankton and zooplankton would decrease in the future under the influence of interactions between acidification and warming.
海洋浮游生物面临着与环境变化相关的新挑战，如海洋酸化、变暖以及富营养化。然而，关于同时发生的环境变化对沿海生态系统中复杂自然群落影响的数据相对有限。在这里，我们对过去三年来渤海的生物和环境参数进行了系统分析，结果表明浮游生物群落对当前不断变化的沿海环境的反应不同，浮游植物的增加和浮游动物的减少。浮游植物和浮游动物的这些不同变化可能是由于目前 pH 值下降导致的酸化以及温度升高导致的变暖这两种效应都有利于浮游植物而不利于浮游动物。此外，水的富营养化以及盐度和重金属汞、锌和砷对浮游植物和浮游动物的动态或多或少有不同的影响。相反，随着气候变化的持续，我们还发现，在酸化和变暖的相互作用的影响下，未来浮游植物和浮游动物的数量都会减少。
