| 摘 要： | 开发了一个陆地生物圈、海洋水圈和大气圈三圈耦合的全球碳循环模式,包括土地利用变化和化石燃料两大人为源的影响,并考虑稳定同位素分馏效应.调试结果表明,该模式能够再现工业革命以来大气CO2的变化历史,能正确反映海洋内部的碳循环过程和全球碳循环中的同位素分馏效应,结果较为理想.进一步分析发现,传统模式可能低估了海洋的碳吸收能力,高估了CO2施肥作用对碳循环的影响.

| Abstract: | The authors developed a 1\|D global carbon cycle model that includes the coupling mechanism of the atmosphere,the ocean and the terrain biosphere,involving two main man\|made sources,i.e. the fossil fuel combustion and the land\|use change.Results show that there is a good relationship between the simulated and measured values of the temperature,phosphate and total carbon in the ocean;simulated atmospheric CO\-2 concentration and 13 CO 2 fit the observed values quite well.It was founded that traditional models may overestimated the influence of the CO\-2 fertilization effect and underestimated the carbon absorbing ability of the ocean. |
