چکیده
The purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelands
of Nodushan, Yazd. The plant species cover and the environmental variables were measured at 9 sites. Soil samples
were taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. Vegetation was classified using twoway
indicator species analysis (TWINSPAN). Data was analyzed using the ordination method of canonical
correspondence analysis (CCA). Results showed that soil texture, organic matter, gypsum, salinity, C/N ratio, and
elevation greatly affected the distribution of vegetation. Anabasis aphylla reflected the high salinity and saturation
moisture content of soils. Ephedra strobilacea reflected a high level of soil gypsum and a high C/N ratio. Artemisia
aucheri was characterized by a gradient of increasing elevation, high organic matter, and available water.
Determining the vegetation-environment relationships at these sites facilitates the improvement and reclamation of
arid and semi-arid shrubland ecosystems.
