\normalsize{
Nowadays continuous utilisation of resources and their sustainable management is of great importance in forest management planning. By studying different principles, criteria and indicators to assess forest sustainability it is evident that one of the important criteria in this context is biodiversity. This study aims at assessment of forest sustainability by species diversity using data obtained from \mbox{0.1\,ha} sample plots commonly applied in forest management plans. The current research was done in Querco-Carpinetum in Patom district, Educational and Experimental Forest of Khayroud. Some parts of above"=mentioned association located in 115 and 117 compartments in which logging practices were done, are referred to as logged area and some parts located in steep slopes of 107 compartment are considered as Unlogged Area. After laying out inventory grid (\mbox{75\,m} × \mbox{100\,m}) in the study area, 40 sample plots were located in Unlogged Area and 39 sample plots in Logged Area. Species and DBH of all tree individuals $>$\mbox{2.5\,cm}, species and two perpendicular crown diameters of shrubs, altitude a.s.l, aspect and slope were recorded on each sample plot. In this research, in addition to richness indices, evenness and heterogeneity indices were also calculated by Ecological Methodology software package. The results showed that number of species and Margalef indices were significantly greater in Unlogged Area than logged area. The evenness indices (Simpson and Smith \& Wilson) were significantly greater in Unlogged Area. All of the heterogeneity indices were significantly higher in Unlogged Area. In shrub layers, index of species number and heterogeneity indices were greater in logged area. }
