AB  - This dataset system displays the spatial layout of frost damage in the permafrost region of Northeast China under human engineering activities such as highways, railways, and crude oil pipelines, revealing the core characteristics of "zonal macroscopic control and corridor microscopic aggregation". The main features include a disaster classification system: based on distribution density and main control factors, the entire area is divided into "high-density engineering disturbance dominant zone", "medium density environment engineering coupling zone", and "low-density seasonal frozen soil background zone". Type identification: Detailed records of typical engineering diseases such as uneven pavement settlement, pavement cracks, hot melt lakes and ponds, freeze-thaw erosion, ice cones, and water damage. Engineering corridor effect: It particularly highlights the disaster aggregation trend along G111, G331, and the China Russia crude oil pipeline (CRCOP), depicting the sharp decrease in frozen soil strength under the "superposition disturbance effect". And micro analysis: including the typical development characteristics of five engineering hubs, namely Mohe, Genhe Ituli River, Xinlin, Heihe, and the southern section of Gagdachi.  The classification system of this dataset (grid values 1-6) corresponds to the types of diseases investigated in the field as follows:  1: Hot melt lake pond.  2: Road cracks.  3: Freeze thaw erosion.  4: Uneven settlement of road surface.  5: Ice cone/ice melting phenomenon.  6: Water destroyed.  Note: The NoData value is 255.
