摘要:

木孜塔格峰冰川变化对南疆水资源具有重要影响。利用1960—2023年的多源遥感数据和深度学习方法提取木孜塔格峰区冰川的面积及末端变化,并分别从冰川单元和地形角度分析冰川变化的区域差异及驱动因素。结果表明:(1)1960—2023年木孜塔格峰冰川总体上呈现退缩趋势,冰川面积退缩速率为0.83 km2·a-1,冰川末端退缩速率为2.21 m·a-1,与中国西北其他冰川相比变化幅度较小。(2)从冰川内部的区域差异来看,冰川面积退缩速率在南向和东向较大,且随海拔和坡度的增加而减小;而冰川末端退缩速率在东、西坡向(4.42 m·a-1和4.01 m·a-1)高于南、北坡向(1.63 m·a-1和1.45 m·a-1)。(3)木孜塔格峰区冰川面积和末端区域变化差异主要受到地形与气候作用的影响,阳坡受更多太阳辐射导致加速融化,低海拔区域则因气温上升而更易发生退缩。研究结果为理解高寒山区冰川对气候变化的响应机制提供了科学依据,对南疆地区水资源管理及生态安全评估具有重要参考价值。

Abstract:

Changes to glaciers in the Ulugh Muztagh region significantly impact water resources in southern Xinjiang. This study extracted glacier area and terminus changes in Ulugh Muztagh region glaciers using multi-source remote sensing data from 1960 to 2023 and deep learning methods. Differences and driving factors were analyzed from the perspectives of glacier units and topographic features. The results show that (1) Overall, Ulugh Muztagh glaciers retreated from 1960 to 2023, with an average annual area loss of 0.83 km2·a-1 and a terminus retreat rate of 2.21 m·a-1. (2) In terms of intra-glacier regional differences, the retreat rate of glacier area was higher on south- and east-facing slopes and decreased with increasing elevation and slope. The terminus retreat rate was greater on east- and west-facing slopes (4.42 m·a-1 and 4.01 m·a-1, respectively) than on south- and north-facing slopes (1.63 m·a-1 and 1.45 m·a-1, respectively). (3) The spatial differences in glacier area and terminus changes in the Ulugh Muztagh region are mainly influenced by topography and climate. Sunny slopes receive more solar radiation, accelerating glacier melt, while lower elevations are prone to retreat due to rising temperatures. These findings provide a scientific basis for understanding the mechanisms by which alpine glaciers respond to climate change and offer important references for water resource management and ecological security assessment in southern Xinjiang.
