  ABSTRACT: In this research diversity of plant species in ecosystem units in an oak habitat of Zagros forests was investigated. For this purpose data on vegetation in 60 sample plots were recorded. Multivariate statistical methods were used to determine ecosystem units. Combined methods of cluster analysis and two-way indicator species analysis were used for determining ecosystem units. To investigate the diversity gradient between ecosystem units, different methods of ordination including principal component analysis and detrended correspondence analysis were used. According to analysis 4 ecosystem units were determined. The diversity was calculated by using Simpson, Shanon, Macintosh, Margalof and Manhanic. Also the Manhanik index has created the most distinction among groups in comparison to other indexes.
