In order to investigate structural diversity of Carpinus betulus type in Golestanprovince 30 modified Whittaker plots by systematic random system were located. Per plot the characteristic of trees and shrubs species(Species name, diameter and height of trees) are recorded. The heterogenity indices of Simpson, Shannon–Wiener, Simpson’s reciprocaland number of equally common species were used for the quantitative data. Toward better understand from diversity condition inhorizontal and vertical composition of stand, the diameter divided in 10 cm classes and Method of Mohajer and the height divided in 10m height classes and dominant height, then number of diversity of each class extracted by Ecological Methodology software V.7. Theresults showed with increase of diameter and height classes, decrease species diversity. Also regeneration layers diversity has significantdifference with trees layers. Thus, the study of biodiversity changes in different diameter and height category cause ecologically preciseperspective in management of forest stands.Key words: structure diversity, indices diversity, diameter and height classes.
