Carbon sequestration is research hot for addressing climate change and global system change. In this paper, combined with the concept of carbon sequestration and carbon sink, we make a comparative analysis on various carbon sequestration pathways for carbon dioxide capture and sealing, impact factor of carbon sequestration, and ecosystem service function. The results indicate that carbon sequestration by terrestrial ecosystem is the most safe and effective process; terrestrial ecosystem carbon sequestration impact on human and ecosystem health is less than geological and ocean carbon sequestration; ocean carbon sequestration easily leads to ocean acidification and irreversible damage to marine ecosystem; as it is difficult to predict the crustal movement, the geological carbon sequestration exist many unpredictable risks. Therefore, the utility of natural capacity of carbon sequestration by ecosystem and the development of green carbon sequestration technologies is the best choice to reduce the ecological risks of artificial carbon sequestration and CO2 emissions into the atmosphere.

Key words: ecosystem carbon sequestration, terrestrial ecosystem, geological carbon sequestration, ocean carbon sequestration, green carbon sequestration
