| 摘 要： | 利用《中国第二次冰川编目》的数据和卫星图, 结合野外地貌观测, 探讨喜马拉雅山亚东?康马段的冰川平衡线高度(ELA)、分布特征及影响因素。结果表明, 研究区现代冰川平均ELA 为5717 m, 库拉岗日地区稍高, 为5840~5957 m, 白马林岗日地区较低, 为5333~5373 m, 反映气候与地形大势对冰川ELA的控制。此外, 山脉的走向、坡向、冰川地形坡度以及冰川表面冰碛覆盖、雪崩等对冰川ELA有不同程度的影响。

| Abstract: | The second China glacier inventory results and satellite images, combined with field observation of the landscape, are used to discuss the glacier equilibrium-line altitude (ELA) distribution characteristics and influencing factors of Yadong-Kangmar, Himalaya Range. The result shows that the average of modern glacier ELA of study area is 5717 m, Kuragon District on average is 5840?5957 m, Baima Ling Kangri area is relatively low, 5333?5373 m, reflecting the control of climate and terrain trend to glacier ELAs. In addition, there are varying degrees of effects on glacier ELAs on account of the factors like direction, slope, glacier moraine cover, and avalanche. |
