摘要: 根据国内外的研究成果及对我国三江平原沼泽近地层大气 CO2的实测资料,阐述地球表层海洋、农田、森林、沼泽等生态系统及大气的 CO2浓度,以及各自的变化规律。同时论述了大气 CO2含量迅速增加对气候和生态环境的重要影响。

Abstract: Based on the present literature at home and abroad and the data of observing atmospheric carbon dioxide near the surface of the marsh in the Sanjiang Plain,the carbon dioxide concentration fluctuates obviously.Oceans have ability to absorb,store and transfer atmospheric carbon dioxide.The carbon budget between the ocean and the atmosphere would be approximately unbalanced.The major sink for atmospheric carbon dioxide is the ocean,forest and marsh.Plants transfer atmospheric carbon dioxide and water into organic matter by photosynthesis.The respiration and the decomposition of animals and plants emit carbon dioxide into atmosphere.There are clear daily and yearly changes of carbon dioxide concentration in the ecosystems. M.H.calculated the change of atmospheric carbon dioxide concentration from Cambrian period.Because of the increase of burning fossil fuels,atmospheric carbon dioxide concentration raised 25 percent than before the industry revolution,which affects global climatic and environmental changes.It is essential to legislate to control the increase of atmospheric carbon dioxide.
