Title : STUDYING BIODIVERSITY OF PLANT ASSOCIATIONS IN SUTAN-CHAY BASIN IN ARASBARAN, NORTHWEST IRAN
Abstract : Investigation on plant biodiversity in associations (ecosystems) is necessary for understanding their stability. This study aims to investigate biodiversity in the plant associations in Sutan-Chay Basin, and the relationship of these associations with different biodiversity indices. The recognition of plant associations in the study area was carried out based on the Braun-Blanquet method. The biodiversity of the relevés comprising plant associations was calculated on the basis of different indices, including: richness, Shannon, Simpson, Margalef and Fisher. Canonical corresponding analysis was used to study the relationship between relevés’ distributions and indices of biodiversity, and to determine the most important biodiversity indices. The results show that the plant associations in the study area are completely differentiated from each other based on biodiversity indices. Pearson’s correlation coefficient indicated the plant associations are correlated with each of the ecological variables. Based on these correlation coefficients, species dominance is positively correlated with soil pH and clay percentage, while negatively correlated with altitude. Study of the relationship between environmental factors and biodiversity variables, and determining the most important factors on biodiversity of plant associations in a given region, are essential for the management of conservation programs.
