Biodiversity is a combination of all biological diversity, including intra-species genetic diversity, diversity between species, communities and the set of ecosystems in a region and on a wide level in vegetation studies and environmental assessment as one of the important indicators in determining the status of ecosystems and in terms of Determining the situation and reviewing the role of management can be used. Through the study and measurement of plant diversity, it is possible to examine the dynamics of the plant community and the distribution of species in the environment, and by emphasizing the dynamics of ecosystems, appropriate management recommendations can be provided. Measuring diversity, which is one of the most important concepts in ecology, can be done in different ways, such as the use of numerical indices that show the diversity in a sampling unit or a community by presenting a number as a result, and parametric or non-numerical indices that, unlike numerical indices, which cause the loss of information about the species, use all the information and add a new dimension to the ecological methods of diversity. The present article was written with the porpuse of introducing plant diversity indicators and their calculation method with Past software after library and web studies. Past software is used in many fields of biological sciences, earth sciences, engineering, and economics, which can be used to accurately calculate diversity indices.
