Abstract: In Central Yakutia high‐salinity soils are not limited to the active layer. Sometimes, cryopegs are formed that contain highly mineralized, negative‐temperature groundwaters. There is a direct relationship between the ground temperature regime and soil salinity. Anthropogenic influences (i.e. urbanization) can cause intensive salt localization and the formation of taliks (cryopegs) to depths of 5–6 m or more. Copyright © 2000 John Wiley & Sons, Ltd. En Yakoutie centrale, des sols hautement salés n'existent pas seulement dans la couche active. Parfois des cryopegs apparaissent qui contiennent des eaux fortement minéralisées dont la température est négative. Il y a une relation directe entre le régime de température du sol et la salinité de celui‐ci. Des influences anthropogéniques (par exemple l'urbanisation) peut entraîner la présence locale d'une quantité importante de sel dans le sol et la formation de taliks (cryopegs) jusqu'à une profondeur de 5 à 6 m ou même plus.
