On the basis of the theory of thermodynamic potentials of the soil moisture, the fundamental equations of a condition of ideal and real gas Clapeyron-Mendeleev  and van der Waals a number of models for the quantitative description of water vapors sorption isotherms in soils is received. Unlike known empirical analogues, models are physically-proved and adequately reproduce the typical s-shaped form of sorption isotherms in all range of a variation of values of relative pressure of water vapors. Conclusions of the models corresponding equations, their analytical research and examples of the description of the real given water vapors sorption isotherms by soil samples with different genesis and dispersiveness are resulted.

The results of the assessment of heavy metals contents (Zn, Pb, Co, Mn, Cd, Cu, Ni) in soil layers of common chernozem on years (2001-2002 and 2006), seasons (summer, autumn, winter, spring) and elements of relief (placornic watershed areas, transitional systems and accumulation zone) are generalized, the changes in some metals concentrations, especially in their labile forms, on seasons of the year considering the changing ecological factors are discussed.

The results of longterm investigations on tuberous orchids in North-West Caucasus are generalized; along with the common structure of these orchids life form the author analyzed some differences in the development of their individual habitats. The materials on ecology (orography, phytocenotic specialties), the number and the age structure of the 12 species in 132 orchids cenopopulations are given. The dynamic of 3 orchids species in 6 cenopopulations - Orchis punctulata, Orchis purpurea, Platanthera  chlorantha – are analyzed during the period of 1992-2010 years; the annual fluctuations of the age spectrum was observed in relation to meteorological conditions as well as exogenous factors (slide slope).
