Mathematical model of seasonal growth of halophytic plant community with account of environmental factors

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.
