【摘要】 对大亚湾四个季节调查表明、大亚湾海水二氧化碳各组份占总碳比例介于河口与外海之间,HCO₃^-/∑CO₂值为0.89,CO₃^2-/∑CO₂值为0.11,CO₂/∑CO₂值为0.005。文章描述了二氧化碳各组份在大亚湾的时空变化,进行二氧化碳各组份与盐度的回归分析。得出影响大亚湾海水二氧化碳体系主要因素在春季是低盐水与高盐水的混合;在夏季是上层永和下层水的混合;在冬季则是生物动活。更多还原

【Abstract】 According to the investigation in 4 seasons for the Daya Bay, it was shown that the proportionality of each constituent of carbon dioxide to the total carbon in the Daya Bay sea water is between the river mouth and the outer sea. The values of HCO3-/ΣCO2 is 0.89 and CO32-/ΣCO2 is 0.11 and CO2/ΣCO2 is 0.005. The time and space variation for each constitutment of carbon dioxides in the Daya Bay was described. The main factor influencing the CO2 system of sea water in Daya Bay is the mixing of low and high sclinity of water in spring; while in summer it is the mixing of upper andlow layer water, and in Winter it js biological activity更多还原
