| 摘 要： | 随着对大气中二氧化碳浓度的持续增加所产生的潜在全球气候变化问题的认识逐步加深,人们在进一步理解全球碳循环问题的同时,正在寻求遏止大气CO2浓度快速增加的方法。文章在讨论一些可能的途径后,着重探讨了作为其中一种选择的CO2海洋封存的有效性问题。使用北太平洋海洋环流模式,研究了人为隔离CO2在海洋中的行为。在北太平洋中选择了1个位置,在不同的深度人为投放CO2。模拟结果表明,隔离有效性随隔离的深度增加而增加。总的来说,当注入深度超过1500m,其海洋中隔离CO2在50a后仍可达注入量的95%以上。当隔离深度超过2000m后,深度增加对隔离效果的影响变小,50a后的差异均小于1%。

| Abstract: | With the recognition of the issue of potential global climate change caused by the continuing increase in atmospheric CO2,scientists are seeking for the method of how to retard rapidly increasing atmospheric CO2,while they are probing for the global carbon cycling. After discussing some possible approaches,this study emphasizes on exploring the effectiveness of sequestration of CO2 in the ocean as one of the options. A basin-wide ocean general circulation model of the North Pacific is used to study the beha... |
