Abstract:
Field investigations of yields of halophytic meadow plant communities were performed near of Lake Kurinka in
the central part of the Republic of Khakasia in 2004 - 2006. A mathematical model has been constructed to
describe the growth dynamics of different plant communities of halophytic meadows as dependent upon the
temperature factor and the salinity level of the soil. Results of field investigations and model studies show that
there is a correlation between plant growth and the temperature of the air for plant communities growing on soils
containing the lowest (0.1%) and medium (1.84%) salinity levels. It has been proven in model studies that for
plant communities growing on high-salinity (3.58%) soils, not only the temperature of the air but also the
salinity level of the soil should be taken into account.
