Résumé
Saline habitats are primarily related to arid and semi-arid areas, but today it is noted an increasing percentage of salt affected soils in the world, caused by impact of climate change on the one hand and anthropogenic activities contributing to the secondary salinization process on the other hand. Inland saline soils, as a type of intrazonal and very rare ecosystems, represent a real challenge in research from an ecological, biological, floristic, phytocoenological and applicative aspects. The aim of this research is to determine the syntaxonomic characterization of halophytic plant communities, as well as floral and vegetational diversity of saline habitats with ecological analysis using indicator values, analysis of life forms and floral elements. The special value of studying salines gives unique database of all phytocoenological releves, spatial data from various sources on particularly important halophytic species and halophytic communities, such as rare, endangered and endemic, as well as the most resistant plants on salt "euhalophyte" and plant communities. The methods of the numerical cluster analysis enabled the assessment of the status and revisions of syntaxons of typical halophytic classes of Therosalicornietea and Festuco-Puccinellietea, as well as the Molinio-Arrhenatherete class on slighty salinized soils. The analyzed data set contains 1638 phytocenological releves of the classes Therosalicornietea, Festuco-Puccinellietea and Molinio-Arrhenatheretea. Also, a significant contribution to the study of halophytic vegetation is also the classification of halophytic communities from southern Serbia. By analyzing the whole phytocoenological database it is made 12 clusters, logically divided into the classes Therosalicornietea, Festuco-Puccinellietea and Molinio-Arrhenatheretea. Then, the classes of Therosalicornietea and Festuco-Puccinellietea were analyzed separetly, where 35 clusters were obtained up to the level of communities. Cluster analysis has shown that higher syntaxonomic categories have not changed much compared to traditional classification...
