海洋碳循环与海洋生态系统动力学

在讨论了目前海洋碳循环研究的现状和存在的问题基础上,分析了海洋生态系统动力学在海洋碳循环中的作用.早期的碳循环研究着重在无机碳循环,随着研究的深入,考虑简单生物地球化学过程甚至带显式生态系统的碳循环模式正在逐步发展.指出了碳循环研究的未来方向,除了要更加准确理解物理过程外,发展带显式生态系统的碳循环模式是一个重要的研究方向.为此,要研究生态系统动力学中的某些关键过程的参数化方法,确定一些重要的参数值.期望今后的模式可更加准确地用于研究海洋生态系统和碳循环对全球变化的响应.

Ocean carbon cycle and marine ecosystem dynamics

On the basis of discussion of present status and problems involved with research on the marine carbon cycle,the role of marine ecosystem dynamics in ocean carbon cycle is analysed.Early studies of the carbon cycle emphasized on the cycle of inorganic carbon.As the research is carried on in a deep going way,the carbon cycle model with a simple biogeochemical process even with an explicit ecosystem is being developed.The future research is pointed out that it includes a better understanding of the physical processes and development of the marine carbon cycle model with an explicit ecosystem.For this reason methods of parameterisation of some key processes should be studied in the marine ecosystem dynamics,and values of some parameters should be determined.It is expected that the future models can be used more precisely to study the response of the marine ecosystems and carbon cycle to global changes.
