| 摘 要： | 文中用包含海洋化学过程和一个简单生物过程的三维碳循环模式模拟了海洋对大气CO2 的吸收 ,并分析了碳吸收的纬度分布。模拟工业革命以来海洋对大气 CO2 的吸收表明 :海洋碳吸收再加上大气 CO2 的增加只占由化石燃料燃烧、森林砍伐和土地利用的变化而释放到大气中的 CO2 的 2 /3。1 980～ 1 989年期间海洋年平均吸收 2 .0 5Gt C。海洋人为 CO2 的吸收有明显的纬度特征。模式计算的海洋 CO2 的吸收在总量与纬度分布上与观测结果比较相符。

| Abstract: | A three dimensional ocean carbon cycle model , which is a general circulation model coupled with simple biogeochemical processes , is used to simulate CO 2 uptake by the ocean. The OGCM is used a modified version of the Geophysical Fluid Dynamics Laboratory modular ocean model (MOM2). The ocean chemistry and a simple ocean biota model is included. Principal variables are total CO 2 , alkalinity and phosphate. The vertical profile of POC flux observed by sediment traps is adopted, the rain ratio ,a ratio of production rate of calcite against that of POC, and the bio-production efficiency should be 0.06 and 2 per year , separately. The uptake of anthropogenic CO 2 by the Ocean is studied. Calculated oceanic uptake of anthropogenic CO 2 during the 1980's is 2.05 Pg per year. The regional distributions of global oceanic CO 2 are discussed. |
