工业革命以来人类活动排放到大气中的主要温室气体有C02、CH4、N20等,其在大气中的含量增加引起吸收地表辐射能量的增加,改变了地表一大气辐射平衡,造成了地表温度升高。本文研究了温室气体含量增加同其吸收地表辐射能量的关系;比较了不同温室气体含量引起的吸收地表辐射能量变化的差异,提出了温室效应对不同温室气体浓度变化的敏感性的概念。通过对敏感性的分析,得出了不同温室气体含量的变化对温室效应影响的强弱关系。
Since the industrial revolution, the main greenhouse gases which human activities released into the atmosphere of are C02, CH4, N20, etc. It makes globe warming that the increasing abso- rption of terrestrial radiation caused by the changes of GHGs concentration changed the radiation balance between the surface and atmosphere. In this paper, we discussed the relationship between the increasing amounts of the GHGs in atmosphere and their Greenhouse effects. At the same time, we compared the variation of different GHG's Greenhouse effect and calculate every GHG's sensitivity to its concentration changes. Through the analysis of its sensitivity, combined with the annual growth rate of GHGs emissions, this paper made appropriate predictions on Greenhouse effect trends to different GHGs in the future.
