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.
The morphological characteristics of the moraine ridge in the Little Ice Age are influenced by many factors. Post-differential GPS measurements are used to measure and study the moraine ridge pattern of the small glacial glaciers of 6 glaciers in the eastern and middle parts of the Qilian Mountains. Three glaciers face the north, Three glaciers are facing south, and more detailed parameters such as related area, surface area and volume of moraine ridge in the Little Ice Age are obtained.The results show that the size of the moraine ridge in the Little Ice Age of Qilian Mountains tends to decrease gradually from east to west, On the 7th glacier in the Lenglingling Glacier, the moraine ridge is the largest, with an area of 11.4 × 105m2 and a surface area of 13.8 × 105m2, with a volume of 11.8 × 107m3. The smallest is the glacial ridge , With an area of 1.9 × 105m2, a surface area of 2.67 × 105m2 and a volume of 1.36 × 107m3. In the Qilian Mountains, the regional climate difference is likely to be the main factor contributing to the differences in moraine ridges in the Little Ice Age.
