【摘要】 碳循环及全球变暖已成为影响气候变化、人类生存环境和经济共同发展和安全的重大问题,该问题已引起全球科学、政治、外交政策等部门的重视。工业革命前,碳循环是碳在大气、海洋和陆地生态系统间的流动。工业革命以来,化石燃料的使用使贮存于地质碳库中的碳参与短期碳循环。因森林和草原开垦等土地利用增加的CO2排放量加重了大气的负担;另一方面造林和再造林形成CO2汇。大气CO2增加导致的气候变化反馈过程影响碳循环。着重探讨碳循环的由来、生态系统与碳循环的科学相关、在碳循环方面我国需要解决的问题和科学技术方法以及碳循环系统的科学研究方法和改进等问题。提出应从控制人类活动入手平衡全球碳循环收支的观点。更多还原

【Abstract】 In recently years, the study on carbon cycle has been given rise to by sciences, politics, and government etc. It also can be recognized as an important issues which have influence on global human living environment, climate changes and economic development in the global scales. In the pre-industrial period, the carbon cycle was Just a carbon flux among the atmosphere, ocean and terrestrial ecosystem. The exchange between carbon pools had been kept in a kinetic equilibrium. Since the industrial period, human activity has been a critical disturbing force to the global carbon cycle. The carbon stored in the geological carbon pool has been a part of short-term carbon cycle because of the use of fossil fuel. The increase of CO2 by land use, such as forest and pasture reclamation, has aggravated the burden of atmosphere. However, afforestation and reforestation became sink of CO2. The feedback of climate change resulted from increasing CO2 in the atmosphere influences the carbon cycle. Many scientists thought that the terrestrial ecosystem might absorb more carbon than estimated at present. But the terrestrial ecosystem merely played a role of buffer. CO2 emitted by human activity will only go to the ocean ultimately. While the ocean assimilate regular carbon annually. Under standing the complexity of the carbon cycle and the linkages to physical, biogeochemical and ecological processes and human influences requires a comprehensive research strategy and a new level of scientific and programmatic integration. In this paper, the carbon cycle issues, the relationship between ecosystem and carbon cycle, and some development methods and technological studies have been discussed. It is necessary to study the carbon cycle and its impacting on the climate change and human living environment in future. It was pointed out that the human activity should be restrained to balance the global carbon cycle.更多还原
