| 摘 要： | 可以近似地把地质历史时期的碳循环看做为在沉积碳酸盐和沉积有机碳化学库之间的平衡。碳循环研究直接关系重建地球古大气、古海洋、古气候和古环境演变的历史，关系正确认识沉积矿产的成因。现在，人们已经对显生宙时期、对晚元古代碳循环进行了较多的研究，并取得了进展，但是对整个元古代和太古代碳循环的研究工作十分薄弱。预料元古代和太古代碳循环研究将成为未来地球科学重要的前沿研究领域。我国存在适于元古代碳循环研究的地质条件，建议开展相应的研究工作.

| Abstract: | Carbon cycle,to a first approximation,can be considered a balance between the carbon in the sedimentary carbonate reservoir and the organic matter reservoir.Study of carbon cycle is related directly to reconstruction of the history of evolution of paleo-atmosphere,paleooceanography,paleoclimate and paleoenvironment of the Earth,and has a great help to understanding the formation of sedimentary ore deposits.So far,study of the Phanerozoic and the latest Proterozoic carbon cycle has been in rapid progress.However,study of the whole Proterozoic and Archaen carbon cycle is weak.It is expected that carbon cycle during the earlier history of the Earth will be a major subject in the future geoscience.The Proterozoic strata in China are suitable to study of carbon cycle and therefore relative works should be carried out in this research area. |
