title: [Hydrochemical characteristic analysis of melting water flow in Keqikaer Glacier, Tianshan (west) Mountains].
abstract: In order to study the melting water chemical characteristics in the Keqikaer Glacier, Tianshan(west)Mountains, the samples were collected from June to September in 2003. The result is found that: (1) The pH value is between 7.35-8.52, the order of which is:river water > glacier melting water > lake water on glacier > precipitation. (2) The various ionic concentrations of melting water are lower than other three kinds of samples, and average is 24% of river water. (3) Comparing and analyzing hydrochemical difference among various precipitation forms, the author found that inhomogeneous ionic concentration of rainwater is higher than the others. (4) Next, the water samples at different altitude have been analyzed, which shows that inhomogeneous ionic concentration of altitude effect is very remarkable. It is expected that if altitude is lower, the eluviation is led by glacier melting can influence the enviro-information record of ice layer.
