AB  - This dataset is the distribution data of ice content in permafrost in Northeast China, combined with measured drilling and pit exploration data. Driven by terrain factors, vegetation factors, meteorological factors, and soil and thermal conditions factors, a machine learning method (random forest) is used to construct the model. The underground ice is mainly thicker in the central area of the Greater Khingan Range. The reliable accuracy enables this permafrost ice content data to serve as a calibration benchmark and historical reference for simulating permafrost ice content in Northeast China under the background of global warming. The data format is GeoTIFF, with a spatial resolution of approximately 1km, and the projection coordinate system is Albers_ConicalEqual-Area.
