Abstract: The temperature data at 3 altitudes of active layer in No.5 Glacier, Yanglong River, Qilian Shan, measured in the summer of 1977 are analysed to see the situation of heat transfer. It is verified that the principal heat exchange in active layer, over 3 m below surface, is conduction. A modified equation for temperature regime is drawn. The relationship between mean ice temperature and depth is found to be linear. The vertical temperature gradient in this layer is greater than that needed for geothermal flux to travel through it by a factor of 3.5-8. Hereby most glaciers in Qilian Shan, several ten metres in thickness, may partly reach melting piont at their base. Perhaps the relatively great vertical temperature gradient is a feature of continental type glaciers in China. The temperature regime in infiltration zone, being different from that in other zones below it, is characterized by a high inner temperature with a small inner amplitude on the one hand, a low surface temperature with a great surface amplitude on the other.
