AB  - The monitoring dataset of active layer water and thermal processes (moisture and ground temperature) at Beiluhe site from July 2002 to August 2004 is the monitoring data of active layer water and thermal processes (moisture and ground temperature) on various underlying surfaces of the observation site. On June 24, 2002, the layout plan for the monitoring site of frozen soil environment in Beilu River was determined, and drilling data was collected for the site layout. The main purpose and significance of establishing this site is to study the influence of different underlying surface types on the process of permafrost activity layer; Study the influence of different underlying surface types on the hydrothermal state of permafrost active layers; Study the differences in surface temperature under various types of underlying surfaces, and use temperature and N-factor theory to infer surface temperature and annual range, and further apply them to permafrost environmental assessment models; Study the hydrological conditions and stability of slopes, as well as the impact of the Qinghai Tibet Railway project on slope hydrological conditions and changes in surface water runoff paths. Attempting to select several vegetation cover types based on the natural monitoring holes of the Beiluhe Qinghai Tibet Railway experimental project, and adding encrypted monitoring of subsurface temperature. Types of supplementary underlying surfaces: desert grassland, alpine grassland, alpine meadow, surface insulation materials, vegetation removal engineering types, gravel pavement.
