Abstract

Changes in species diversity may result from relationship between species, environmental and human factors. In this study, the role of environmental and human factors (grazing and land use changes) was investigated on the species diversity changes in pastures around the Veshteh village located in middle Taleghan region. Five plant types were identified in this region that one of them was from abandoned agricultural lands, another one was near the watering point with intensive grazing and 3 other types include average, light and without grazing types. Sampling was done using 4 transects with 150 meters length and 15 plots of 1 m2 were placed 10 meters apart from each other along each transect. In the beginning and end of each transect a profile excavated and soil samples from 0- 30 cm depth were taken. After data collection, heterogeneity, UNIFORMITY and SPECIES RICHNESS indices were calculated using Past and Ecological methodology. PRINCIPLE COMPONENT ANALYSIS also used to determine the most important factors affecting SPECIES RICHNESS. Results of PRINCIPLE COMPONENT ANALYSIS showed that texture, organic matter, nitrogen, height, electrical conductivity and PH affect the diversity changes in the region. Besides environmental factors, effect of human factors such as grazing and land use conversion was investigated on species diversity but these factors didn’t recognized effective on diversity of this region, but despite the impact of these factors, the diversity indices values were high. Rank-abundance model also was used to illustrate the distribution pattern of species in studied types. Results indicate that all types had log normal distribution and represent relatively stable plant communities with number of species that their average abundance was very high.
