摘要: 西大滩煤矿冰川区冰、雪和河水的阳离子分析表明,随海拔升高,阳离子浓度减小。在雪坑剖面的污化层位,离子出现高值,在洁净层出现低值,表现出明显的季节变化特征。降雪过程中,初期离子浓度较高,以后逐渐降低,到一定时段则达到稳定。

Abstract: Abstract The concentrations of cations decrease with altiude within glacier ice,snow and riverwater in the district. Higher concentration appears in dirty layer and lower one in clear layerin the snow profiles, showing obvious seasonal variation. In a snowfall event coneentrationsare higher at the beginning and then gradually decrease to a steady value.

Key words: Meikuang glacier, glacier ice, snow, river water, cations
