摘要
Atmospheric air temperature data from 92 stations in China＇s radiosonde network were used to analyze changes in the freezing level height （FLH）, glacier snow line, and ice edge from 1958-2005 （48 years） and to examine the impact of these changes on the cryosphere. In general, the FLH, glacier snow line, and ice edge exhibited latitudinal zonation, declining from south to north. Trends in the FLH, glacier snow line, and ice edge showed spatial heterogeneity during the study period, with prevailing upward trends. Temporally, the FLH, glacier snow line, and ice edge trends differed on various time scales.
