Glaciers in the Tibetan Plateau have experienced change in recent decades with the climate change, and the change trend were not homogeneous. The variation of snow line altitude(SLA) can indicate the glacier change. The changes of SLA for glaciers in the western Nyainqentanglha Range can be detected by remote sensing images obtained at the end of ablation season, such as Landsat TM/ETM+/8 OLI and HJ1A images, when eye interpretation technologywere used to extract snow line. Meanwhile, the variation trend of temperature and precipitation recorded by 4 meteorological stations adjacent to the research area were analyzed, so as to find its influence on glacier change. The results showed that SLA of total studied 28 glaciers rose obviously in 2004-2013. SLA on north slope as a whole raised 14 m/a, while 4.9 m/a on south slope. The air temperature in the studied area rose obviously, precipitation rose slowly since 1964. Climate warming is the main cause for glacier recession. Glaciers on north slope experienced more negative mass balance than south slope, because the rate of air temperature increase on the north is higher than that on the south.
