摘要：
Our research investigates the effects of climate change on the soil forming minerals and vegetation of a meadow solonetz. On the study site, located at the Szabadkigyos Steppe, the analyses of the mineral composition, salt, Na and humus content of soil samples, and the botanical mapping of the entire territory were performed in 1979 and 2005. Results indicate that due to climate change the ground water table has descended significantly, and the past 25 years has brought considerable changes on the site. Alteration of hydrological conditions generated changes in the mineral composition and chemical parameters of the soil, simultaneously with which the vegetation of the area transformed too. It has been proved that botanical structure is in a strong correlation with soil composition.
