Abstract

Sustainability of productions in agricultural ecosystems depends on conservation and amplification of biodiversity. This study was conducted to determine the planting area, species richness, species evenness and biodiversity of different agronomical, horticultural and livestock productions in Kerman province. For this purpose, information about planting area of agronomical and horticultural plants and population of various livestock species for different regions of Kerman was gathered. The results showed that Jiroft and Kerman regions had the highest and Rafsanjan had the lowest agronomical planting area. The highest planting area of horticultural plants was observed in Jiroft and Rafsanjan and the lowest amount of the trait was gained in Baft. The highest and lowest livestock population was related to Jiroft and Ravar, respectively. Jiroft and Kerman regions were contained the highest species richness of agronomical (20 and 22 species, respectively) and horticultural (34 and 31 species, respectively) productions. Wheat, Pistachio and sheep were the dominant species in majority regions of Kerman. The highest Shannon index was gained in Jiroft (2.27) and Kerman (1.99) for agronomical, Jiroft (2.31) and Baft (2.05) for horticultural and Kerman (0.99) for livestock productions. Rafsanjan was included the lowest Shannon index in all agricultural productions. Jiroft had the highest species evenness of agronomical (0.76) and horticultural (0.66) and Kerman was contained the highest amount (0.75) for livestock productions in different regions of Kerman province. The results showed that correlation of Shannon index with species evenness was higher than planting area or species richness.
