On June 24, 2002, the layout plan for the frozen soil environment monitoring site of Beilu River was determined, and the site was equipped with drilling data. The research purpose and significance of establishing this site are mainly to study the impact of different types of underlying surfaces on the process of permafrost activity layer; Study the hydrothermal state of different underlying surface types on the active layer of frozen soil; 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 it to the assessment model of frozen soil environment; Study the hydrological conditions and stability of slopes, as well as the impact of the Qinghai Tibet Railway project on the hydrological conditions of slopes and the changes in surface water runoff paths. Based on the natural monitoring holes of the Beilu River Qinghai Tibet Railway experimental project, several types of vegetation cover were selected and encrypted monitoring of subsurface temperature was added. Supplementary types of underlying surfaces: desert grasslands, alpine grasslands, alpine meadows, surface insulation materials, vegetation removal engineering types, and gravel roads
Monitoring data of active layer hydrothermal processes (moisture and ground temperature) on various underlying surfaces at the observation site from July 2002 to August 2004
