摘要
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。
Spatial distribution of mountain permafrost in northern Tien Shan, Central Asia
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.
