摘要：

报道了2007年北极Svalbard群岛Longyearbyen地区2处雪坑样品和8个河流样品中主要阴、阳离子浓度。对比该地区1996年雪坑样品离子浓度发现,2007年雪坑中离子浓度普遍降低,该地区河流水化学受陆源离子影响为主,主要是河流流经裸露基岩过程中对岩石的侵蚀作用造成的。

Abstract:

The study reported major ion concentrations in snow pits and river water samples collected from Longyearbyen area,Svalbard in 2007. Comparison with major ion data of snow pits collected in 1996 showed that the concentrations of the most ions in the snow pits of 2007 are much lower than those of 1996. Ionic concentrations of river water are dominated by continental source,which is contributed by the rock corrasion when the melt water flows through the bedrocks.

Key words: Arctic, Svalbard, snow pit, river, ionic concentration
