【摘要】 工业革命以来人类活动产生了大量二氧化碳气体(CO2)并释放到大气中。CO2溶于海水,造成海水pH值降低,改变海洋碳酸系统的平衡。海洋酸化对海洋生态系统特别是钙化生物构成威胁。颗石藻作为主要的钙化浮游生物,在海洋碳循环过程中起着重要的作用。大多数培养实验表明CO2浓度上升会促进颗石藻光合作用。而海洋酸化对不同种或不同品系颗石藻钙化作用产生不同的影响。更多还原

【Abstract】 Since the Industrial Revolution a large amount of carbon dioxide(CO2) as a result of human activities has been released into the atmosphere.Dissolution of CO2 into seawater reduced the ocean pH and changed the balance of the ocean carbonate system.Ocean acidification threatens the marine ecosystems,especially calcifying organisms.Coccolithophore are major calcification plankton and play an important role in the ocean carbon cycle.Most of the culture experiments showed that the rise of CO2 concentration would promote photosynthesis in coccolithophores.Ocean acidification has various effects on the calcification of different coccolithophore species or strains.更多还原
