Abstract
To clarify the current state of mountain permafrost, we researched the distribution, classification, and movement of rock glaciers as an indicator of mountain permafrost in the Kyrgyz Ala-Too Range using field survey, GIS/RS techniques and aerial photograph interpretation. At the examined site, MAAT is -4.62 and MAGST is -1.47 on rock glacier (3500 m asl.) showing environment of mountain permafrost. The distribution of rock glaciers shows the discontinuous permafrost zones are located above 2800 m a.s.l. on the north part and above 3200 m on the south part of the Kyrgyz Ala-Too Range.
为了明确山地多年冻土的现状，我们采用野外调查、GIS/RS技术和航空照片解译等方法，研究了作为山地多年冻土指示物的岩石冰川的分布、分类和运动。在考察点，岩石冰川(海拔3500 m) MAAT为-4.62,MAGST为-1.47，显示了山地冻土环境。岩石冰川的分布表明，吉尔吉斯阿拉图山脉北部海拔2800 m以上，南部海拔3200 m以上为不连续多年冻土带。
