TALK ABOUT THE FUNCTIONS OF CO_2 IN THE ATMOSPHERE

大气中二氧化碳的含量虽低,但在生物学、地球物理学方面的作用极为显著。生物和人类的活动造成二氧化碳的不断变化、转换和平衡,而生物和人类则在此过程中赖以生存。

Co2 contained in the atmosphere plays distinguished roles in biology and geophysics. This paper has discussed the interaction of CO2 with activities of living things and human beings' And it has also discussed the change conditions of CO2 amount contained in the almosphere and the functions which CO2 performs in the agricultural ecosystem. This paper provides valuable reference for us to analyse the factors offeeting crops yieled and the cules of climate change.
