摘要: Medium-term (5.5 years) changes in the cover of major species “Artemisia saline puszta” (Ass) and “Pannonic Puccinellia limosa hollow” (PPlh) grassland communities Kiskunsag region, Hungary, were monitored analyzed relation to abiotic factors (e.g. air temperature, precipitation, soil moisture, salinity alkalinity). Soil varied considerably, indicating leaching desalinization surface layers as most typical process occurring region. Yearly average covers Artemisia santonicum Plantago maritima negatively positively related salinity, respectively, accordance with their salt tolerance. Multiple regression analysis showed pH be important determining yearly plants at Ass. Increasing increased A. P. maritima, but decreased Podospermum canum. At PPlh, groundwater had a positive effect lakewater level negative on limosa. The results provide information ongoing properties resulting plant composition these Hungarian salt-affected grasslands.
