Geocryologists at the Institute of Geography of the Mongolian Academy of Sciences are working on the generalization of the permafrost research materials obtained over the past years. In 1996, a publication on the geocryological character-istics of the economic zones was prepared, and a monograph on permafrost conditions in Mongolia was initiated.
As a result of many years of observations of the surface temperature regime on the protected Bogd Khan Mountain near Ulaanbaatar, N. Sharkhuu analyzed regional regularities in the quantitative alteration of permafrost conditions depending on latitudinal belts, slope exposure, winter air temperature inversion, and snow and vegetation covers. Results are reflected in a report and permafrost map (1:125,000) compiled in 1996 for the national atlas of this protected mountain.

On the basis of generalizations of field and experimental observations of frost heaving at many sites, Dr. Sharkhuu and A. Anand in 1996 compiled a map (1:100,000) of frost heaving distribution in the Selenge River basin. The mapping approach provides the basis for compiling similar maps of the discontinuous permafrost region at small and medium scales. The methods and results of compiling the maps were presented at the International Conference on Geotechnic-96 in Ulaanbaatar.
