【摘要】 冰冻圈是气候变化的灵敏指示器，地表温度和近地表气温则是指示器直接感测的信号，是回溯冰冻圈演化历史、监测当前状态、模拟未来变化的关键参量。受恶劣环境、复杂地形、低可达性及众多特殊下垫面等因素的综合影响，当前青藏高原温度的地面观测困难、站点稀少，而遥感已成为温度获取的有效手段。本文聚焦地表温度和近地表气温，阐明了地面观测、卫星和无人机等遥感反演估算的相关方法手段，梳理和总结了学术界围绕青藏高原冰冻圈取得的研究进展，介绍了遥感温度参量在青藏高原冻土、湖冰、冰川等方面的应用。本文总结了青藏高原冰冻圈对温度遥感获取的挑战，探讨了未来值得着重开展的研究方向。更多还原

【Abstract】 The cryosphere serves as a sensitive indicator of climate change, while land surface temperature and near-surface air temperature are signals directly sensed by the indicator. They are key parameters for tracing the evolution history of the cryosphere, monitoring the current state, and simulating future changes. Due to a combination of adverse environmental conditions, complex terrain, low accessibility, and numerous unique underlying surfaces, ground-based temperature observations are challenging and sparsely distributed in the Qinghai-Tibet Plateau. Remote sensing has become an effective means of temperature acquisition. Focusing on land surface temperature and near-surface air temperature, this paper elucidates the related methodologies for ground-based observations, satellite, and unmanned aerial vehicle(UAV) remote sensing retrievals, and summarizes the research progress made by the academic community around the cryosphere of the Qinghai-Tibet Plateau. Furthermore, this paper discusses the applications of remote sensing temperature parameters in frozen ground, lake ice, glaciers, and other aspects of the Qinghai-Tibet Plateau. Challenges in temperature remote sensing acquisition in the Qinghai-Tibet Plateau cryosphere are summarized, and future research directions worthy of emphasis are explored.更多还原
