| 摘 要： | The rational usage of low productive cryogenic landscapes in the North-Eastern part of Russia is impossible without carrying out special engineering preparation 1]. The preventing from negative that often has destructive cryogenic processes in the area of ice-covered permafrost soils, provided by its thawing into the marginally necessary depth in the whole area. The simplest and the most effective engineering method of faulting as an age-old stock (reserve) of surplus moisture in the form of ice from the upper parts of permafrost soils is the creation of continuous furrows net on the whole surface. This method also raises the fertility of soils, reduces acidity, and raises microbiological activity and the degree of internal structure decaying.

| Abstract: | The rational usage of low productive cryogenic landscapes in the North-Eastern part of Russia is impossible without carrying out special engineering preparation 1]. The preventing from negative that often has destructive cryogenic processes in the area of ice-covered permafrost soils, provided by its thawing into the marginally necessary depth in the whole area. The simplest and the most effective engineering method of faulting as an age-old stock (reserve) of surplus moisture in the form of ice from the upper parts of permafrost soils is the creation of continuous furrows net on the whole surface. This method also raises the fertility of soils, reduces acidity, and raises microbiological activity and the degree of internal structure decaying. Thermophysical calculations and the results of the field study in the experimental firing grounds are the available evidences of this method which raises the thermal stability of cryogenic landscapes while mastering of global climate changes in different parts of cryolithozone. |
