According to the remote sensing records on glacier area in the typical regions of China,as well as the meteorological data of air temperature and precipitation at 139 stations and the 0 ℃ isotherm height at 28 stations,the variation of glacier area in China and its climatic background in the past 50 years was discussed.The initial glacier area calculated in this study was 23982 km 2 in the 1960s/1970s,but the present area was only 21893 km 2 in the 2000s.The area-weighted shrinking rate of glacier was 10.1%,and the temporal-interpolated annual percentage of area changes (APAC) of glacier was 0.3% a -1 since 1960.The high APAC was found at the Ili River Basin and the Junggar Interior Basin around the Tianshan Mountains,the Ertix River (a tributary of the Ob River) Basin around the Altay Mountains,the Hexi Interior Basin around the Qilian Mountains,etc.The retreat of glaciers was affected by climatic background,and the influence on glaciers of the slightly-increased precipitation is counteracted by the significant warming in summer.
