Beech trees is one of the most important species of Hyrcanian forests that plays an important role in the process of forest ecosystem succession and the ectomycorrhizal fungi play an important role in forest health and sustainability and protecting trees against pathogens in forest ecosystems. This study was conducted to classify beech habitat with environmental factors and ectomycorrhizal fungi in Sangedeh forest. A total of 45 sample plots of 1000 square meters were randomly assigned to three 300 m altitude classes, namely altitude range of 1200 to 2100 m above sea level and elevation factors (m), slope, slope direction, breast diameter, tree height, Degree of canopy cover, litter type, litter depth, stand type, soil acidity, electrical conductivity, phosphorus, carbon, nitrogen, potassium were investigated. The results of correlation of variables with components were determined and ectomycorrhizal fungi with first principal component included variables such as altitude, nitrogen, potassium, phosphorus, carbon, electrical conductivity and tree height and the second principal component of altitude variables, canopy cover, depth Litter, nitrogen, carbon and stand type had a significant positive correlation (1%). Principal component analysis results showed that first floor height (1800 to 2100 m) with sea level elevation, soil acidity, litter depth, phosphorus and potassium, second floor height (1500 to 1800 m) with forest cover canopy percentage, litter depth There was a positive correlation between mass type, nitrogen and carbon and height of third class (1200 to 1500 m) with stand type, tree height and electrical conductivity.
