AB  - This data provides a detailed characterization of the spatial pattern of freeze-thaw disasters in the permafrost region of Northeast China under the coupling effects of climate change and human engineering activities. The resource content covers the distribution of disaster types from large discontinuous permafrost areas to seasonal permafrost transition zones, with a focus on identifying six major disaster types: uneven road settlement, hot melt lakes and ponds, road cracks, freeze-thaw erosion, ice cones, and water damage.  Resource characteristics: (1) Large spatial span: covering the main permafrost areas of Daxing'an Mountains and Xiaoxing'an Mountains. (2) High precision: Using a scale of 1:100000, it reveals the distribution characteristics of "north dense and south sparse, high dense and low sparse". (3) Strong engineering relevance: Highlighting the disaster gathering trend of linear engineering corridors such as highways (G111, G331, etc.), railways, and Sino Russian crude oil pipelines. (4) Typical representatives: Five typical regions including Mohe, Genhe Ituli River, Xinlin, Heihe, and the southern section of Gagdachi were selected for micro analysis.
