AB  - The susceptibility assessment dataset for freeze-thaw disasters in Northeast China is based on on-site investigation data of freeze-thaw disasters in Northeast China. Five machine learning models (GAM, GAM, GBM, RF, ANN) and their weighted integration methods are used to construct a 1000 meter resolution freeze-thaw disaster susceptibility assessment product for Northeast China. The data expresses the spatial susceptibility level of regional freeze-thaw disasters in grid form, which can be used in fields such as permafrost disaster monitoring, risk assessment, ecological environment research, and regional planning.  The levels of freeze-thaw disasters are divided into the following 5 categories:  1: Extremely low  2: Low  3: Medium  4: High  5: Extremely high
