%X The 2011 dataset of permafrost temperature profiles in the upper reaches of the Heihe River was collected from early June to early August 2011, based on monitoring data obtained from permafrost surveys conducted at the western branch of the main stream source of the Heihe River. By following the section of the Erga Highway from the hot water Osaka Pass to the asbestos mine fork, as the altitude decreases, a total of 7 temperature measuring holes T1, T2, T3, T4, T7, T5, and T6 are arranged in sequence, and temperature measuring tubes are installed for ground temperature monitoring. The instrument used is a thermistor thermometer developed by the State Key Laboratory of Frozen Soil Engineering, Institute of Environment and Engineering in Cold and Dry Regions, Chinese Academy of Sciences. The resistance value is measured with a Fluke multimeter, and then converted into a temperature value with an accuracy of ± 0.05 ° C. In order to reduce the impact of roads on the temperature of boreholes, it is required that the vertical distance between all boreholes and the road should be at least 100 m when determining the hole location. Except that T1 temperature hole at Reshuidaban Pass is located in the south of Erga Road, the other six boreholes are located in the north of the road.
