摘要：

在综述南极大气气溶胶研究现状的基础上，以１９９１年６月Ｐｉｎａｔｕｂｏ 火山和同年９月Ｈｕｄｓｏｎ 火山喷发为例，分析了大气气溶胶的源、汇及其物理化学特性、空间分布和大气传输过程，探讨了火山喷发所产生的大气气溶胶对全球以至南极环境的影响。

Abstract:

The present study situation of the aerosal in Antarctica was reviewed in this paper. Taking the volcanic eruption of Pinatubo Mt. and Cerro Hudson Mt. (from during Jun,1991 to September,1991) on the aerosol as an example,the effect of the volcanic eruption activity on aerosol was analyzed. This paper studies the source,The sink and the physicochemical characteristics of the aerosol,and also analyses the mass-size distribution and transitive processes of aerosol in aerosphere.It was shown that the effect of the aerosol from these volcanic eruption on the global environment ant Antarctic environment.
