黑河上游多年冻土温度剖面数据集（2011）

在2011年6月初至8月初，在黑河干流源头西支开展多年冻土调查，沿二尕公路热水大坂垭口至石棉矿岔口之间路段，随着海拔高度的降低，依次布设测温孔T1、T2、T3、T4、T7、T5和T6等共7眼,并布设测温管进行地温监测。所用仪器为中国科学院寒区旱区环境与工程研究所冻土工程国家重点实验室研制的热敏电阻温度计，用Fluke万用表测定其电阻值，再换算成温度值，精度±0.05 °C。为了降低公路对钻孔温度的影响，在定孔位时要求所有钻孔离公路的垂直距离均保证至少大于100 m。除热水大坂垭口T1温度孔位于二尕公路的南侧以外，其余6眼钻孔均位于公路的北侧。

From early June to early August 2011, a permafrost survey was conducted on the western tributary of the headwaters of the main Heihe River. Along the road segment between the Reshuidaban Pass and the asbestos mine intersection on the Erga Highway, a total of 7 temperature monitoring boreholes (T1, T2, T3, T4, T7, T5 and T6) were arranged sequentially with decreasing altitude, together with temperature measuring pipes for ground temperature monitoring.

The instruments used were thermistor thermometers developed by the State Key Laboratory of Frozen Soil Engineering, Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences. Their resistance values were measured with a Fluke multimeter, then converted to temperature values, with an accuracy of ±0.05 °C.

To mitigate the impact of the highway on borehole temperatures, all boreholes were required to maintain a vertical distance of at least 100 m from the highway during site selection. Except for the T1 temperature borehole at the Reshuidaban Pass, which was located on the south side of the Erga Highway, the remaining 6 boreholes were all situated on the north side of the highway.
