In the northern Tien Shan located in semi-arid area, glacier and mountain permafrost are important water resources that supply water to the city and irrigation farmland. Although the current state of glacier and mountain permafrost should be clarified as important tasks (Sorg et al., 2012), information about the mountain permafrost is limited in Ili Range (Marchenko et al., 2007). We investigated the spatial distribution of mountain permafrost in the Teskey, Kungoy, ili Ranges, the northern Tien Shan, based on satellite data analysis and field observation. As a topographic indicator of mountain permafrost, we classified rock glaciers into active/inactive or fossil using DInSAR (Differential SAR Interferometry) analysis with ALOS-2/PALSAR2 data.
