北麓河场地活动层水热过程监测（2002-2004年）数据集是2002年7月-2004年8月观测场各种下垫面的活动层水热过程（水分和地温）监测数据。2002年6月24日，确定了北麓河冻土环境监测场地布置方案，场地布设钻孔资料。设立本场地的研究目的和意义主要为研究不同下垫面类型对冻土活动层过程的影响；研究不同下垫面类型对冻土活动层的水热状态；研究各种不同的下垫面类型下地表温度的差异，并利用气温和N—因子理论来推测地表温度和年较差，进一步应用到冻土环境评价模型中去；研究斜坡水文状况和斜坡稳定性以及青藏铁路工程对斜坡水文状况的影响及地表水径流路径变化的影响。试图以北麓河青藏铁路试验工程的天然监测孔为基础，分别选取几种植被覆盖类型，增设加密地表以下温度的监测。补充下垫面类型：荒漠草原、高寒草原、高寒草甸、地表铺设保温材料、铲除植被工程类型、砂砾路面。

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.
