从1998年3月7日至1999年11月23日历时21个月,在南极中山站连续采集89个海洋气溶胶样品,本文提供全部样品的13种化学元素Cu、Pb、Zn、Cd、Fe、Al、Mn、Cr、V、K、Na、Ca、Mg含量的实测值.研究表明中山站气溶胶化学成份的含量具有季节性变化的特征.通过相关分析、因子分析、富集因子等方法判别不同时间段中山站气溶胶化学成份的来源. Eighty nine aerosol samples of 6～7 days duration were collected from Mar. 1998 through Nov. 1999 at Zhongshan Station, Antarctica. This article present the content of thirteen chemical elements: Cu,Pb,Zn,Cd,Fe,Al,Mn,Cr,V,K,Na,Ca,Mg. This study have demonstrated that the content of elements in aerosol at Zhongshan Station appeared to be characteristics of seasonal variation, which were related to features of meteorological element. Meanwhile discussion of sources discrimination of the elements in the marine aerosols during defferental time duration using methods of factor analysis, correlation analysis and enrichment factor. 国家自然科学基金资助项目(49976022)
