Abstract: 

In natural ecosystems, site classification can be used as a model to determine the quality of forest ecosystems based on ecological factors. Therefore, vegetation analysis based on plant communities and soil properties was performed in Kheyroudkenar forest – Nowshahr. Based on Braun - Blanquet method and using ANAPHYTO software vegetation data were analyesed, and associations recognized. Morevere, ecological groups and differential species were determined based on phytosociological data using TWINSPAN. Afterwards, depending on one sample selected in each landform class, the area with differential species was recognized for soil study. Results showed that two communities constitute the major part of the study area, Rusco-Fagetum and Carpineto–Fagetum. Soil variables that played the most important role for expantion of Rusco-Fagetum associaton were depth, silt, P and pH, while in Carpineto–Fagetum important were clay, sand, Sp, N and C.
