Forty Year's Study of Glacier Temperature in China

HUANG Mao huan (Lanzhou Institute of Glaciology and Geocryology, CAS, Lanzhou Gansu 730000, China)  
Temperature measurements have been made on 29 glaciers in China since 1959 The regional thermal features of glaciers are now revealed It is distinguished that there are three categories of temperature distribution in China, i e , cold, temperate and polythermal Temperate glaciers are located in the southeastern Tibetan Plateau The heat conduction in the surface layer and the heat transfer within a glacier can be quantitatively described Two dimension temperature distribution is gained for the Glacier No 1 at the headwaters of the Urumqi River in the Tianshan Mountains and for the Chongce Ice Cap in the West Kunlun Mountains Geothermal flux is derived from measurements down to or closed to the bottom The Tibetan Plateau is an area with high geothermal flux The author suggest to measure more ice temperature by using the boreholes for extracting ice core, however, there is no need to repeatedly measure the temperature within the surface layer
