全球气候变化下的海洋颗石藻生理生态学响应研究进展

海洋颗石藻是一类重要的浮游植物功能群，可同时进行光合作用和钙化作用，在全球海洋碳循环中起到重要作用。海洋是人类排放CO₂一个重要的汇，大气CO₂浓度迅速上升导致海洋酸化、升温、营养盐浓度及混合层内光照强度变化。这些复杂的环境变化与人类活动对海洋环境的其他扰动相叠加，同时作用于海洋浮游植物，对海洋颗石藻的生长施加多重压力，进而对海洋碳循环产生复杂的反馈效应。本文主要综述单一环境因子（CO₂浓度、温度、营养盐及光照水平）以及全球气候变化下多重环境因子的复合作用对海洋颗石藻的生理生态学效应及其对海洋生物地球化学循环的潜在影响，并结合近年来的研究进展，分析这一热门研究领域未来的发展方向。

Physiological and ecological response of marine coccolithophores to global climate change: a review

Coccolithophores are one of the marine phytoplankton functional groups, playing important roles in the marine carbon cycle through both photosynthetic and calcification processes. The oceans are considered as important sink of the anthropogenic CO₂. The rapid increase in atmospheric pCO₂ since the industrial revolution has caused the trend of global climate change, including ocean acidification, global warming and changes in the nutrient concentrations and irradiance in the mixed layer. These complex changes in environmental conditions will affect the physiology and ecology of marine phytoplankton simultaneously, which is the so-call environmental multiple stress. The response of coccolithophores to changes in multiple environmental drivers will also have complex feedback to marine carbon cycle. This review mainly overviews the current understanding of the effects of both single environmental driver (CO₂ concentration, temperature, and nutrient and irradiance levels) and the interaction of multiple environmental drivers on the physiology of coccolithophores and its implications on the marine biogeochemistry. Based on these recent research advances, the future research perspectives are also summarized.
