中文摘要：

海洋酸化状况是全球海洋生物多样性的威胁之一。在海洋快速酸化的影响下，海洋生物物种丰度发生变化，从而改变海洋生物群落结构；缓慢的海洋酸化，使海洋生物具有一定的适应能力，但是与海洋生物生境息息相关，海洋酸化的间接影响成为生态的关键。对近年来海洋酸化对海洋生物多样性的影响进行了综述，并对海洋生物应对海洋酸化存在的问题进行了分析。

英文摘要：

Ocean acidification is a threat to marine biodiversity in the world.Under the influence of rapid ocean acidification, the abundance of species in ocean was changed, which resulted in the variation of the marine biological community structure.The slow acidification of the o-cean could made the marine organisms to have the ability in the adaptability to its environment.However, the marine habitats were closely re-lated and the indirect efficiency of ocean acidification on it became an ecological key point.The effect of ocean acidification on marine biodi-versity was summarized and the problem and development trend of marine biological response to ocean acidification were analyzed and dis-cussed.
