摘要 Relationships among ground ice, Quaternary soil type, vegetation cover, digital terrain model (DTM), permafrost ground temperature and topographic units are applied. Using comprehensive evaluated method and coding interpolation, spatial distribution of ground ice in permafrost regions along Qinghai-TibetanHighway (QTH)is modeled according to GIS spatial analysis. Comparing with result, model precision can be approached to 81.2%. Its study precision can satisfy engineering need for a small-scale Relationships among ground ice, Quaternary soil type, vegetation cover, digital terrain model (DTM), permafrost ground temperature and topographic units are applied.
