AB  - This dataset is the distribution data of permafrost burial depth in Northeast China, combined with measured drilling and pit exploration data. Driven by terrain factors, vegetation factors, meteorological factors, soil and hydrological factors, machine learning methods (random forest) are used to construct the model. The burial depth of permafrost is relatively small in the northern part of the Greater and Lesser Khingan Mountains, and relatively large in the southern and western parts of the Greater Khingan Mountains. The reliable accuracy enables this frozen soil distribution data to serve as a calibration benchmark and historical reference for simulating the depth distribution of permafrost in Northeast China under the background of global warming. The data format is GeoTIFF, with a spatial resolution of approximately 1km and a geographic coordinate system of WGS 1984.
