中文摘要	对天山乌鲁木齐河源1号冰川（以下简称1号冰川）积累区海拔4130m处12个月、每周1次的气溶胶和表层雪样品进行了分析．结果表明，1号冰川气溶胶与表层雪中Ca~(2＋)、Mg~(2＋)的平均浓度均在夏季最高，冬季最低．气溶胶中Ca~(2＋)、Mg~(2＋)浓度变化规律极其相似，二者在一年内出现两次峰值，第1次出现在春季，第2次出现在夏末秋初．表层雪中这两种离子浓度变化趋势也相似，峰值均出现在夏季，且Ca~(2＋)浓度峰值的出现稍早于Mg~(2＋)，二者浓度在冬季都有所升高，尤其Ca~(2＋)更为显著．气溶胶和表层雪中对应离子间在整体变化趋势上较为相似，且在日时间尺度上的对应关系有显著的特点．相应离子的对应关系，可能受粉尘微粒的溶解、离子的清除比率、离子的淋溶强弱等性质的影响。
英文摘要	Studying the relationship between atmospheric aerosol and surface snow is a part of the PGPI （Program for Processes Investigation）, which was initiated in July 2002 by the Tianshan Glaciological Station. 49 aerosol and 49 surface snow samples were collected simultaneously at the PGPI site （4 130 m a. s. 1., in,, the percolation zone） on the Glacier No. 1, Tianshan Mountains, from January 2004 to January 2005. The analyses of Calcium and Magnesium indicate that they have the similar changing tendency both in aerosol and surface snow. The mean concentrations of Ca~(2＋) and Mg~(2＋) appeared a maximum in summer and a minimum in winter. The concentrations have two peaks in aerosol, one in spring and the other in late summer. The peaks of the concentrations in surface snow appeared in summer. The concentrations of Ca~(2＋) and Mg~(2＋) show an increasing tendency in winter, especially for Ca~(2＋). Temporal patterns of the two ion concentrations are similar between aerosol and surface snow, showing that the changes in snow basically reflect the changes in aerosol in a long term. Dissolution of dust, scavenging ratio and elution of ions may be responsible for the concentration change in surface snow. The Glacier No. 1 is surrounded by vast desert areas and located at the central Asia, the source of Asian dust. The Asian dust maybe brings in the high concentrations of Ca~(2＋) and Mg~(2＋).
