      6O年来大气中二氧化碳浓度数据的趋势方程研究

      Research on tendency equation about the concentration data of carbon dioxide in the atmosphere over the past 60 years

      摘要:
      通过讨论已有的60年来大气中CO_2浓度数据的分布状态,采用趋势分析方法,给出了具体趋势方程形式.与冰芯分析或观测数据对比结果表明,趋势方程曲线与已有数据基本符合,随后初步给出了2010年至2016年间大气中CO_2浓度预测值.
      Abstract:
      In this paper, by discussing the existing distribution of the CO_2 concentration data in the atmosphere over the past 60 years, and adopting the tendency analytical method, the concrete tendency equation forms of the CO_2 concentration are presented. Further more, the comparison result between the curve of the theoretical equation and the data curve of CO_2 concentration from the ice cores analysis or the observation is given. The result shows that the tendency equation curve agrees well with the existing data. Subsequently, the predictive data of the CO_2 concentration in the atmosphere from 2010 to 2016 are suggested tentatively.
