%X From early June to early August 2011, the permafrost survey was carried out in the West Branch of the source of Heihe River. Along the section from shuishuidaban Yakou to Shimian mine fork of erga highway, with the decrease of altitude, seven temperature measuring holes (T1, T2, T3, T4, T7, T5 and T6) are arranged successively, and temperature measuring pipes are arranged for ground temperature monitoring. The instrument used is a thermistor thermometer developed by the State Key Laboratory of Permafrost Engineering, Institute of cold and arid environment and engineering, Chinese Academy of Sciences. The resistance value is measured by fluke multimeter, and then converted into temperature value with an accuracy of ± 0.05 ° C. In order to reduce the influence of highway on borehole temperature, the vertical distance between all boreholes and highway is required to be at least 100 m. Except that T1 temperature hole of shuishuidaban pass is located in the south of erga highway, the other 6 boreholes are located in the north of the highway.
