Abstract: 

Plant associations determination can be considered as a master key for knowledge on stand evolution, dynamic and environmental factors relations. Therefore, this study was carried out to find out the relationship between plant associations and physiographical condition to assess the vegetation profile. The study site is located in Noshahr, Kheiroudkenar research forest. The vegetation was sampled by using Braun-Blanquet method and plant associations were determined on the basis of vegetation data analysis such as TWINSPAN and ordination analysis (i.e., DCA) methods. ARCGIS software was used to map the plant associations and physiographical situations and to study their relation. The results showed that six determined associations were: Parrotio-Carpinetum, Querco-Carpinetum, Alno–Fagetum, Rusco-Fagetum, Carpino-Fagetum and Fagetum orientalis. The distribution pattern of the plant associations in different physiographical condition indicated that all associations occurred in most slope and aspect classes. However, their spatial pattern in different altitude classes were not the same. Parrotio-Carpinetum was located at the altitude of 200-800 meters above sea level. Where as Querco-Carpinetum was occurred at 600-1400 m.a.s.l. and mainly in south and southwest orientations. The associations which were dominated by beech were located at 800-1600 m.a.s.l., in which mixed beech communities occupied more area.
