| 摘 要： | 冰川作为气候变化的指示器,在气候变暖的趋势下呈加速退缩的趋势。冰川消融加速对海平面上升、区域水循环和水资源可获取性均有重要影响。冰川体积作为冰川研究的一项重要内容,越来越被研究者关注。围绕极地冰盖、山地冰川体积研究概况,较系统地总结分析研究冰川体积变化的方法,主要包括传统测量方法、统计公式法、冰川地形测量法和遥感监测法,现代冰川体积变化的研究也由传统的实地测量、统计公式法等向遥感监测研究发展,并分析各方法在主要冰川类型中的应用情况。借助遥感手段监测冰川动态变化可有效解决高寒山区资料受限的问题,成为冰川学发展的重要趋势。

| Abstract: | Glaciers, which are sensitive indicators of climate warming, are generally thinning and retreating at an accelerated rate. Glacier melting has wide-ranging consequences such as sea-level rise, regional water cycle, and water availability. Studies of ice volume change, which is a significant part of glacier studies, are increasingly concerned by more researchers. In this article,volume changes of ice caps and mountain glaciers were discussed. Based on this, study methods of glacier volume or ice thickness change were highlighted. In general, there are four methods of investigating glacier volume change. It has improved from traditional ground-based techniques, empirical equation of glacier area and volume, glacier topographic survey to remote sensing monitoring. Due to its novel, rapid and relatively inexpensive techniques, glacier monitoring using remote sensing technique could effectively solve the limited data of remote location in alpine regions. Remote sensing, GIS and GPS technologies will continue to play a significant role in the estimation of volume or ice thickness of mountain glaciers and ice caps. |
