| 摘 要： | 小冰期冰碛垄形态特征受到众多因素的影响,采用后差分GPS测量方法对祁连山东段、中段共6条冰川的小冰期冰碛垄形态进行了实地测量与研究,其中3条冰川朝北,3条冰川朝南,得到了关于小冰期冰碛垄有关面积、表面积、体积等较详细的参数.结果表明:祁连山小冰期冰碛垄的规模具有从东到西逐渐减小的趋势,最东段冷龙岭7号冰川小冰期冰碛垄规模最大,面积为11.4×105m2,表面积为13.8×105m2,体积为11.8×107m3;规模最小的为最西边的团结峰3号冰川小冰期冰碛垄,其面积为1.9×105m2,表面积为2.67×105m2,体积为1.36×107m3.祁连山地区而言,区域气候差异很可能是造成小冰期冰碛垄规模差异的主要因素.

| Abstract: | The geomorphology features of Little Ice Age moraines are affected by many factors. Six Little Ice Age moraines in the eastern and middle sections of the Qilian Mountains were measured by differential GPS. Three of them face north and the rest face south. Detailed parameters are gotten,such as,area,surface area,volume and other parameters of the Little Ice Age moraines. Research shows that the scale of Little Ice Age moraines reduced gradually from east to west in the Qilian Mountains. The largest one is th... |
