摘要: During the past five decades, fluctuations of glaciers were reconstructed from historical documents, aerial photographs, and remote sensing data. From 1956 to 2003, 910 investigated had reduced in area by 21.7% value, with a mean reduction for individual glacier 0.10 km2. The relative reductions small usually higher than those large ones, which exhibited larger absolute loss, indicating that more sensitive climate change ones. Over ∼50 years, decreased 29.6% Heihe (黑河) River basin 18.7% Beidahe (北大河) basin, two regions Middle Qilian (祁连) Mountain region. Compared other areas region, most dramatic shrinkage occurred mainly resulting rapid rising temperatures. Regional differences changes are related local conditions, proportion different size classes, factors.
