摘要

在存在永久冻土的情况下，来自寒冷冻结地下的负热通量将导致强烈的负WEqT(通常小于-2°C)，而在非冻土上，WEqT将接近0°C或中度负(Haeberli 1973)。因此，WEqT可以很好地指示永久冻土的发生，并有助于区分永久冻土和非永久冻土地区，前提是积雪在冬季早期形成，并保持足够的厚度，使土壤表面不受大气影响。

In presence of permafrost, the negative heat flux coming up from the cold frozen subsurface will lead to strongly negative WEqT (typically less than -2 °C), whereas on non frozen soil, the WEqT will be close to 0 °C or moderately negative (Haeberli 1973). Thus the WEqT can be a good indicator of permafrost occurrence and can help to discriminate permafrost from non-permafrost areas, provided that the snow cover developped early in the winter and remained sufficient to isolate the soil surface from atmospheric influence.
