%X This dataset is the distribution data of permafrost in the Genhe River Basin of the E'erguna area on the western slope of the Greater Khingan Range. Combined with measured drilling and pit exploration data, the model is constructed using machine learning methods (random forest) driven by terrain factors, vegetation factors, meteorological factors, and soil and thermal condition factors. Permafrost is mainly distributed in high-altitude mountainous gentle slopes, hills, and some low-lying areas. The distribution of frozen soil is island shaped or patchy. The reliable accuracy enables this frozen soil distribution data to serve as a calibration benchmark and historical reference for simulating permafrost in the Genhe River Basin under the background of global warming. The data format is GeoTIFF, with a spatial resolution of approximately 30m and a projection of WGS1984_ Albers.
