    This research was aimed at to fit species diversity indices on the tree strata and to analyse the ecological parameters using different sizes of quadrants and transects as sampling schemes. The ecological parameters of abundance, dominance, frecuency and relative importance value were investigated. The results showed that more than 30 tree species were found growing in a mixed uneven-aged forest with a density of over 1000 trees per ha. The difference between two methods of sampling (i.e. quadrant and transect) for diversity estimats is significant at 95% confidence level. The transects provided better estimates for the average diversity of the both study areas in less sampling surface. Several diversity indices were different significantly with different sizes of quadrants and transects. The indices of Shannon, Margalef and Mcltosh were more sensitive to both sampling schemes and to different sizes of quadrants and transects. The analysis of the ecological parameters revealed that Quercus sartorii, Liquidambar styraciflua and Carya ovata had the higher ecological importance in this community.

    Keyworks: species diversity indices, quadrants, transects, relative importance value.
