%X The frozen soil thermal stability classification dataset divides the frozen soil types and thermal stability in the Qinghai Tibet Engineering Corridor through multiple influencing factor experiments, monitoring, and simulations, and analyzes the main distribution areas of different types of frozen soil. This dataset contains two types of data: classification criteria for permafrost thermal stability and criteria for permafrost types (classified by annual average ground temperature) in the Qinghai Tibet Engineering Corridor thermal stability. The first type of data considers the influence of factors such as annual average ground temperature, thermal stability indicators, and changes in human activities on the thermal stability of frozen soil; The second type of data considers the influence of factors such as annual average ground temperature, permafrost thickness, and annual average temperature at the boundary to classify the permafrost types in the Qinghai Tibet Engineering Corridor, and analyzes the main distribution areas of different types of permafrost.
