Abstract: 

In the ecological researches, the plant diversity was important. The goal of this research was inventories of diversity in ecological groups in Kelarabad protected forest area with an area of 59.4 ha. At first step, 77 sample plots (400 m2) were taken systematic randomly. Then obtained data about trees, shrubs and the other plants was analyzed by TWINSPAN method and 4 ecological groups were determined. In the next step diversity indices including: species diversity, evenness and richness indices were calculated in all of 4 ecological groups. The comparison of diversity indices between groups were performed with ANOVA tests. The results showed that Shannon-wiener function and Simpson index in 2nd and 3rd groups are showed more amount then 1st and 4th groups, and there are significant difference between them. The Minhinick index didn’t show any the significant difference between groups, but the highest amount of Margalef index was the in 1st group. The diversity with augmentation of evenness is increasing in 4 groups. Because there are not slope, altitude and geographic aspect, therefore diversity is influenced protection factors in this studied area.
