et al. 2009 )

7.3 Summary

Cryosols cover about 13.8 million km 2 worldwide, of which 83 % occur in the cir-
cumarctic and 17 % in mountains of the high latitudes and high mountains. Because
the active layer is too deep (>1 or 2 m) in mountains with permafrost and in the
sporadic and isolated permafrost zones of the circumarctic, only 63 % of the perma-
frost region contains cryosols. The other soils are Entisols, Inceptisols, Histosols,
and other soil orders.
