【摘要】 <正> 柴达木盆地,位于我国西北内陆干旱区,流域面积28×10~4km~2,其中,沙漠面积约占7×10~4km~2。 冰川被称为固体水库。随着经济建设的迅速发展,特别是在干旱缺水的柴达木盆地地区,查清冰川分布数量,研究利用高山冰雪水资源,使之服务于经济建设,已成为当务之急。柴达木盆地(以下简称盆地)为昆仑山、阿尔金山和祁连山所环抱,在这些高寒山区里,广泛发育着现代冰川,是十分重要的淡水资源。虽然过去曾对盆地边缘的部分现代冰川作过一些考察和研究,但由于资料及测试手段不完备,加之量测和登记冰更多还原

【Abstract】 The glacial inventory data of the inland river systems in the Qaidam Basin have been introduced in this paper. There are 1449 existing glaciers with an area of 1761.10km2 and ice volume of 122.9299km3 in the border mountains of Qaidam Basin. According to the calculation, the annual icemelting water is up to 1.142 billion m3 which provides the basis for the utilization of glacial resource in the bisin.70.3% of glaciers in the Qaidam Basin distribute on the north slope of eastern part of Kunlun Mountain, 27.2% in the south western of Qilian Mountain and 2.5% on the south slope of Aljin Mountain. The characteristic of glacial distribution is that glaciers are small in size and only a few number in the eastern Mountain ranges of the basin, large in size and quite a lot number in the middle mountain ranges of the basin, and medium in size and number in the western mountain ranges of the basin. The glacial area with area larger than 2.00km2 and length longer than 2.0km are 61% of the total area respectively. There are 7 form classifications in glaciers. The largest expanded-foot glacier in the basin is Moluomaha glacier (5Y542H34) in the source area of Taijinar river, and the largest flat glacier in the basin is Dunde glacier (5Y582J2) in source area of Tatalin River which is on the eastern side of Tergun-Daban Shan of Qilian Mountain. The snow-lines height of glaciers are between 4770-5360m in the northern border, and between 4930 -5760m in the southern border of the basin.更多还原
