%X This dataset takes the high latitude permafrost region in Northeast China as the research object, and comprehensively utilizes multi-source remote sensing data with a spatial resolution of 30 meters, surface and underground temperature monitoring data, permafrost type distribution, and engineering interference information to construct a model for predicting and evaluating the stability of permafrost engineering foundations. This dataset quantitatively evaluates the basic stability along the linear engineering line and its impact range. The evaluation results are characterized by a dimensionless stability index ranging from 0.0 to 1.0, revealing the destructive effect of human engineering activities on the thermal balance of permafrost. The data exhibits a significant "linear focus" feature, where the low stability and high risk zones overlap highly with transportation and energy corridors, providing core decision support for regional scale engineering planning and frost damage risk prevention and control.  The core element of this dataset is the stability index (dimensionless, 0-1), which is divided into three levels based on risk level:  High stability zone (0-0.30): Low risk, displayed in green. Mainly distributed within large areas of discontinuous permafrost, with low ground temperature, stable active layer, and minimal interference.  Medium stable zone (0.30-0.60): medium risk, displayed in yellow. Distributed in the transition zone from discontinuous frozen soil with more melting areas to island/sporadic frozen soil.  Low stability zone (0.60-1.0): High risk, displayed in red.  Highly concentrated along linear engineering (G111, G331, CRCOP pipelines, etc.), forming continuous or quasi continuous high-risk zones.
