AB  - This dataset is the result of a special investigation on engineering freeze-thaw disasters conducted in the permafrost regions of Northeast China (including the Greater and Lesser Khingan Mountains and surrounding key corridors). The dataset uses a 30 meter high-resolution grid as the carrier to finely depict the spatial distribution of six typical freezing damages, including hot melt lakes and ponds, road surface settlement, cracks, freeze-thaw erosion, ice cones, and water damage. This data integrates field observation data and remote sensing inversion indicators, revealing the impact of anthropogenic thermal disturbances (roadbed heat absorption, pipeline heat dissipation) on permafrost degradation and disease accumulation in engineering corridors. The data can provide core base map support for the maintenance, disaster warning, and cold region engineering planning of linear projects in permafrost regions such as G111, G331, China Russia crude oil pipelines, and Nenlin Railway.
