摘　　要：全球大气CO_(2)浓度升高,融入海洋中的CO_(2)增加,导致了海洋化学环境发生改变(海洋酸化)。迄今,已有不少研究探讨了浮游植物如何响应海洋化学环境变化和升温,但争议性报道居多,且多数研究局限于对短期酸化或升温的响应。对此,本文以海洋模式硅藻威氏海链藻(Thalassiosira weissflogii)和三角褐指藻(Phaeodactylum tricornutum)为材料,开展长期海洋化学环境变化和温度升高对光化学反应影响的研究。本研究发现酸化短期内会极大抑制威氏海链藻的光化学反应,对三角褐指藻无显著影响。经过长期适应后,当温度升高时威氏海链藻的光化学反应会受到显著抑制作用。The global rise in atmospheric CO_(2) concentration and the increased incorporation of CO_(2) into the oceans have led to changes in the ocean chemical environment(ocean acidification).A number of studies have examined how phytoplankton responds to changes in the ocean chemical environment and warming,but controversial reports are predominant and most of the studies are limited to the response to short-term acidification or warming.In this paper,we used the marine model diatoms Thalassiosira weissflogii and Phaeodactylum tricornutum to investigate the effects of long-term ocean chemical environment changes and warming on photochemical reactions.We found that acidification greatly inhibited the photochemical reactions of P.tricornutum in the short term,and had no significant effect on P.tricornutum.After long-term adaptation,the photochemical reaction of T.weissflogii was significantly inhibited when the temperature was also increased.
