摘要: 在1980年5—9月的阿尔泰山友谊峰(海拔4,374米)科学考察工作中,冰雪痕量元素的研究是以哈拉斯冰川(49°10’N)为重点进行的(采样位置如图1)。此外还进行了湖泊、河流及大气降水样品的采集。本文拟讨论哈拉斯冰川冰雪中痕量元素的特征。

Abstract: The mechanically suspended substance exists abundantly in the river water, so turbid water has a white color.The soluble element content is less than 40mg/l , which is in agreement with the mineralization degree of the glacial ice in Tianshan mountains and Qilian Mountains, but a little lower than that in the atmospheric precipitation in Qinghai-Xizang Plateau of China. The river water belongs to a kind of glacial run-off with low mineralization degree in Northwest China and the mineralization degree of glacial ice at Hars Glacier is the lowest (13.99mg/l) ,coinciding with the mean mineralization degree of atmospheric snowfall in this region.The interrelationship between the trace element in glacial ice and altitude is that the calcium content remains constant, while the magnesium content increasing gradually with the altitude is always more than the calcium content, but the potassium content is close to the sodium content, which is different from other glaciers in Northwest China and should be classified into the subcontinental type.The element enrichment factor in atmospheric precipitation on liars Glacier is different from other mountain glaciers in China.The element enrichment order in Rongbuk Glacier of Mt.Qomolangma is Ca>Na>Mg in Tanggual Mountains Na>Ca>Mg, in the same way in Eastern Kunlun Mountains,on West Qiongtailan Glacier of Mt.Tuomuer in Tianshan Mountains and on the Batura Glacier of Karakoram Mountains and in Qilian Mountains Ca>Mg>Na,but on the Hars Glacier Na>MgNa
