摘    要:总结了南极冰盖中 nss SO4 2 - 和 NO3- 的主要来源 ,通过对南极冰盖中几种主要离子空间分布特征的分析 ,结合南极冰盖中不同区域火山活动记录的时间差 ,认为南极冰盖中的nss SO4 2 - 和 NO3- 很可能是通过远距离高空传输到极地冰雪中 ,具体过程为 :nss SO4 2 - 和 NO3-在对流层顶部平流层底部呈带状输送到极地上空 ,然后辐射下沉 ,再辐散到其他地区

关 键 词:南极  冰盖  nssSO42-  NO3-  传输路径

Abstract:WT5BZ] In this paper we summarized the main sources of nssSO 4 2- and NO 3 -. By analyzing the spatial distribution features of major ions in Antarctic ice sheet and studying on the different times recording the volcanic eruptions in different regions, this paper intends to study the transmission path of nssSO 4 2- and NO 3 -. Results show that nssSO 4 2- and NO 3 - are transmitted to the ice sheet by long distance and high level transmission. The procedure of nssSO 4 2- and NO 3 - transmission is that nssSO 4 2- and NO 3 - are transmitted to the ice sheet at the level between the top of troposphere and the bottom of stratosphere, then nssSO 4 2- and NO 3 - transmitted to the ice sheet surface and spread to other regions.
Keywords:Antarctica  ice sheet  nssSO 4 2-   NO 3 -  transmission path.
