青藏高原北麓河气象站活动层水分监测数据集（2017.1-2018.10）

活动层是多年冻主要特征之一，暖季融化，冷季冻结，呈季节性变化，其中所含水分的多少会对冻土的温度有一定影响，从而影响冻土稳定性。该数据集主要是活动层水分数据，监测站点位于92°E，34°N，海拔4600米，监测场地地势平坦，植被类型为高寒草甸，北麓河气象站采用的水分探头为CS615，分别在地表以下10cm、20cm、40cm、80cm、160cm的5个深度上进行水分监测，该数据集的时间间隔为1天，是通过30分钟一次的数据的平均值，监测期间数据稳定、连续。通过结合土壤热通量和冻土地温等资料可以开展活动层的热变化过程以及变化机理等科学课题。

The active layer is one of the core characteristics of permafrost. It thaws in warm seasons and freezes in cold seasons, exhibiting seasonal variations. The moisture content within the active layer has a certain impact on frozen soil temperature, thereby affecting permafrost stability.

This dataset mainly contains active layer moisture data. The monitoring station is located at 92°E, 34°N, with an altitude of 4600 meters. The monitoring site features flat terrain and alpine meadow vegetation. The Beiluhe Meteorological Station uses the CS615 moisture probe to monitor soil moisture at five depths: 10 cm, 20 cm, 40 cm, 80 cm, and 160 cm below the surface. The temporal resolution of this dataset is 1 day, calculated as the average of data collected every 30 minutes. The data collected during the monitoring period is stable and continuous.

By combining datasets such as soil heat flux and permafrost ground temperature, scientific research topics including the thermal evolution process and its underlying mechanism of the active layer can be conducted.
