| Abstract: | This study reports recent changes of the Urumqi Glacier No.1 during 2012—2018 based on RTK-GPS， terrestrial laser scanning （TLS） and unmanned aerial vehicle （UAV） data. Our analysis suggests that the Urumqi Glacier No.1 had experienced accelerated shrinkage for the investigated periods. The result shows that the total area decreased by 0.07 km2， with a decrease rate of -0.01 km2 a-1 from 2012 to 2018， the terminus retreat rate was 6.28 m·a-1 and its retreat rate from 2015 to 2018 was higher than from 2012 to 2015. Urumqi Glacier No.1 experienced a mean mass loss of （-1.13±0.18） m w.e.·a-1 with lowering surface elevation from 2012 to 2018 and mass loss mainly occurred in the ablation area. It is consistent by comparison between glaciological and geodetic mass balances of the Urumqi Glacier No.1 for 2012 to 2018. The mass loss during 2012—2018 （-0.64 m w.e.·a-1） was greater than that during the period 1980—2012 （-0.47 m w.e.·a-1） indicating that the Urumqi Glacier No.1 continued to shrink recently. |
