%X a multidisciplinary analysis was carried out to determine geomorphological units in the desert region of central and west argentina and their relationship with plant communities. three east-west transects were studied, resulting in the identification and classification of three main geomorphological environments: a dune relief, a sandy loess plain and an ancient fluvial plain of the san juan river. the dominant plant community in the dune environment, characterized by wind processes, was found to be panicum urvellanum; in the sandy loess plain, characterized by wind and ancient fluvial processes, suaeda divaricata in association with atriplex lampa and schismus barbatus predominates; and in the ancient fluvial plain, where salt processes occur, atriplex crenatifolia is the main community. the richest abundance and widest diversity were found in the sandy loess plain and in silty soils and the least abundance and diversity in the ancient fluvial plain and s2 and s3 clay soils.
