Summary: | 大气中的二氧化碳(Carbondioxide,CO2)溶解到海水中会导致其碳酸盐系统平衡改变,包括海水中二氧化碳分压(Partialpressureofcarbondioxide,pCO2)的升高和海水pH值的下降,该过程被称为海洋酸化。束毛藻是生活于热带与亚热带寡营养盐海域的固氮蓝藻,它对海洋初级生产力及海洋氮循环有着极为重大的影响。 迄今为止,已经有许多关于海洋酸化对束毛藻影响的研究,但是,由海洋酸化过程带来的海水pCO2升高和pH值的下降分别将如何影响束毛藻,目前尚不清楚。本课题通过改变人工海水中总溶解无机碳(Dissolvedinorganiccarbon,DIC)的浓度及pH值,调. The dissolution of rising atmospheric carbon dioxide (CO2) in the ocean leads to a shift in seawater carbonate chemistry, including an increase in partial pressure of carbon dioxide (pCO2) and a decrease in pH, changes collectively referred to as ocean acidification. Many researches have been conducted to investigate the impact of ocean acidification on Trichodesmium, a colonial nitrogen (N2)-fi. 学位:理学硕士 院系专业:环境与生态学院_环境科学 学号:33120141151684
