AB  - This dataset is the permafrost buried depth data of the Kamaran River Basin in the Tahe area on the east slope of the Daxinganling Mountains. Based on the surface temperature (GST) of the HOBO monitoring station in the study area, a "surface temperature-environmental factor" regression model is constructed to calculate the melting index. Calculate the E factor through the classification assignment method. The Stefan model is used to simulate the thickness of the active layer of permafrost. The R2 of the simulation results is 0.73. The data format is GeoTIFF, with a spatial resolution of approximately 30 m, and the projection is WGS_1984_Albers.
