Abstract

Understanding the role of plant species in plant composition is very important in studying climate change, understanding the properties of ecosystems such as sustainability, resilience and evaluating ecosystems. Therefore, this study conducted with the aim of classifying, studying the biological and vegetative form and determining the strategy of plant species based on the functional characteristics of plants, in Gandman wetland of Borujen city, Chaharmahal and Bakhtiari province. For this purpose, some species taken in the growing season in the period of July. Sampling performed by random-systematic nesting method. Thus, 55 main plots containing 275 sub-plots established along 11 transects. The characteristics of plant species in the plots measured according to the method of Pierce et al. 2013 and based on this method, the strategy of the species was determined according to the 1977 Grimm theory. A total of 39 plant species belonging to 12 plant families were studied.

Hemicryptophytes (45%) were one of the most important structural groups in the region's biological spectrum by Rankier method. Chorological study and extraction of corotypes showed the predominance of elements in the Iran Turani region (IT) (36.8%) and several regions (23.7%). CS / CSR strategy has the highest frequency of 15% (6species) and the frequency of each strategy according to the percentage of plant species selection of each strategy showed that CS strategy with 27% frequency is the most dominant strategy.
