摘要：

本文作者于1987～1988年由国家南极考察委员会派遣随JARE29赴日本南极昭和站、瑞穗站和阿斯加等站进行考察,根据日本同行提供的1984～1988年昭和站大气中二氧化碳浓度连续变化资料以及相应年份该站年平均气温资料进行研究,结果表明:从1984年到1988年该站大气中二氧化碳浓度变化趋势与该站年平均气温变化趋势是相当一致的,二者呈明显正相关。此外,还给出该地区从1984年到1988年大气中二氧化碳浓度变化的年增长率,其值分别为1.21ppmV/年(1984～1985年)、1.35ppmV/年(1985～1986年)、1.68ppmV/年(1986～1987年)和1.99ppmV/年(1987～1988年)。

Abstract:

On the basis of the analysis of atmospheric carbon dioxide concentration variations and the annual mean air temperature at Syowa Station, Antarctica in 1984-1988 period, the following results are easily obtained. (1) The annual mean values of the atmospheric carbon dioxide concentration are gradually increased and equal to 342.59, 343,80, 345.15, 346,83 and 348.82 ppmv for 1984, 1985, 1986, 1987 and 1988, respectively. Its growrh rates of the year to year are 1.21,1.35, 1.68 and 1.99 ppmv/yr, for 1984-1985, 1985-1986, 1986-1987 and 1987-1988, respectively and are raised year after year. The seasonal variations are observed and the maximum concentration in spring and the minimum concentration in autumn. (2) The increased tendency of the annual mean value of the atmospheric carbon dioxide concentration is consistent with that of the annual mean value of air temperature*
