格尔木-那曲、共玉、中尼雅万流域高等级公路沿线冻土温度和活动层厚度（2021-2024）

数据集是青藏铁路和青藏公路路基各5个监测断面路基下部和天然状态下0.5-15m深度冻土地温观测数据，数据时间2021.1-2024.8，每月10日、20日和30日数据。同时包含了计算获得的天然状态下活动层厚度和路基下部多年冻土上限的数据。冻土地温数据可以清楚地了解天然状态和路基下部多年冻土的热状态的多年变化特征，天然状态下活动层厚度和路基下多年冻土上限的多年变化特征。同时，冻土地温数据也可以计算获得多年冻土顶板深度的年平均温度和年平均地温数据。

This dataset contains permafrost temperature observation data collected at depths of 0.5–15 m under the subgrades of 5 monitoring sections along the Qinghai-Tibet Railway and Qinghai-Tibet Highway, as well as under natural undisturbed conditions. The data covers the period from January 2021 to August 2024, with observations taken on the 10th, 20th, and 30th of each month. Additionally, the dataset includes derived values of active layer thickness under natural conditions and the permafrost table depth beneath the subgrades. The permafrost temperature data allows for clear elucidation of the multi-year variation characteristics of the thermal regime of permafrost under both natural conditions and the subgrades, as well as the multi-year changes in active layer thickness under natural conditions and the permafrost table beneath the subgrades. Furthermore, the annual mean temperature and annual mean ground temperature at the permafrost table depth can be calculated using the collected permafrost temperature data.
