人类活动与天山现代冰川退缩

在系统分析了中亚天山山两个长期进行物质平衡监测的乌鲁木齐河源１号冰川和图尤克苏冰川的资料，并引用其他研究成果后，发现中亚天山现代冰川１９７０年－１９９０年比１９３０年－１９７０年明显的退化。近２０年多来，中亚天山冰川加速退缩，解体，与被工业排放污染了大气有关。

RELATIONSHIP BETWEEN THE HUMAN ACTIVITIES AND THE RETREATING OF MODERN GLACIERS IN THE TIANSHAN MOUNTAINS

The enviroment change of glaciers can be shown by the fluctations of glacier mass balance, the long-term Observation of glacier mass balance is therefore of significant scientific and practical values. In this paper, after the systematic analysis of datum from two glaciers in the Tianshan Mountains in Central Asian(Urumqi No. 1 Glacier at the headwater of Urumqi River and Tuyuksu Glacier near the Alna-Ata City of Kazakhstan, it is found that two glaciers retreated more significantly during the period of 1970-1990 as compared with the period from 1930 to 1970. In recent 20 or more you, the rapid retreating and disintegration of glaciers in the Tianshan Mountians are considered to ha the result of increased atmosphere pollution. bodes the air pollution from industrial wastes release, whinny dusts from the dry up inland lakes, abandon cultivate land and salinity soil were among the are of atmosphere pollution, and has a even more direct and significant role in contributing to atmosphere pollution in Central Asian. The consequences of human activities changed the circulation system in the inland areas in Central Asian, and the increased air pollution accelerated the velocity of retreating of ,modern glaciers. Water is the life source, and also is the basic condition for human existence and development in arid region, more attentions should be paid to the problems of modern glaciers in the Tianshan Mountains in Central Asian.
