我国冰川温度研究40年
Forty Year’s Study of Glacier Temperature in China
【摘要】 1959 年以来, 先后在29 条冰川上进行了大量的观测, 冰川温度面上的状况已清楚可区分出冷冰川、温冰川和冷温复合冰川3 类其表面层的传热学、内部热交换可作定量描述今后应向纵深、高精度和综合性发展, 重复过去的浅孔观测已不再必要
【Abstract】 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
