Description :
Based on the glacier area variation records in the typical regions of China monitored by remote sensing, as well as the meteorological data of air temperature and precipitation from 139 stations and the 0°C isotherm height from 28 stations, the glacier area shrinkage in China and its climatic background in the past half century was discussed. The area-weighted shrinking rate of glacier and the interpolated annual percentage of area changes (APAC) of glacier were calculated since 1960. The retreat of glacier was affected by the climatic background, and the influence on glacier of the slight-increased precipitation was counteracted by the significant warming in summer.
