The Eurasian study and development of concepts of permafrost-affected soils began over a century ago, in two centers, Russia and Germany. In Russia, permafrost-affected soils cover about 65% of the total area. Pioneers of Russian soil studies were faced with Cryosols. Unfortunately, for a long period, the results of these soil studies were published only in Russian and poorly known elsewhere. And since there are several thousand Russian publications on permafrost-affected soils, for this paper we have analyzed only monographs and some principal papers. |
