| 英文摘要 | Ice and snow chemistry of alpine glaciers is crucial for the research of regional atmospheric environment change. fresh snow samples were weekly collected from urumqi glacier no. 1 in the tianshan mountains, xinjiang, china, and the chemical characteristics and seasonal variations of major ions, mineral dust, delta(18)o and trace metals were measured. results show that the concentrations of major ions in the snow are ca(2+) > so(4)(2-) > nh(4)(+) > no(3)(-) > cl(-) > na(+) > mg(2+) > k(+), in which ca(2+) is the dominant cation, and so(4)(2-) is the dominant anion. all major ions have close positive correlations with each other except no(3)(-). delta(18)o shows positive correlation with air temperature change during the study period. mineral dust particle and major ionic concentrations in fresh snow have obvious seasonal change, with high concentration in spring but low concentration in summer and autumn, which indicates that the chemical mass input from asian dust activity to snow is very significant. temporal changes of trace metals in fresh snow, e.g., cd, pb, zn, al, fe, have shown that human-induced pollution of central asian region also has large contribution to the snow chemistry on alpine glaciers of the tianshan mountains. |
