Influenced by the Indian monsoon, the Kangri Karpo Mountains (KKM) of the southeastern Tibetan Plateau is the most humid part of the plateau, and one of the most important regions with numerous monsoon temperate glaciers. Glacier mass balance estimates have been strongly negative in the KKM over recent decades, but the spatiotemporal characteristics of surface velocity are poorly understood. Using phase-correlation feature tracking on Landsat images, this study estimates spatiotemporal variabilities of monsoon temperate glaciers for the period of 1988–2019. Results show that a significant slowdown was observed below an elevation of 4900 m, while an accelerated ice flow was found at an elevation of 4900–5800 m over the past 30 years. The trend of slowdown was −0.1 m a−1 dec−1 during 1988–2000, and then it increased to −0.5 m a−1 dec−1 during 2001–2019.

青藏高原东南部康日喀布山脉季风温带冰川地表速度时空变化特征

受印度季风影响，青藏高原东南部的康日喀布山脉（KKM）是高原最湿润的地区，也是拥有众多季风温带冰川的重要地区之一。近几十年来，KKM 的冰川质量平衡估计值一直为负值，但人们对地表速度的时空特征知之甚少。本研究利用 Landsat 图像的相位相关特征跟踪，估计了 1988-2019 年季风温带冰川的时空变化。结果表明，在过去的 30 年中，在海拔 4900 米以下观察到明显减速，而在海拔 4900-5800 米处发现冰流加速。放缓趋势为-0.1 ma-1十二月-11988-2000 年间，然后增加到 -0.5 ma-1十二月-12001-2019 年期间。
