aljThe Study of Relationship between Nabka Dune Volume and Plant Morphology Tamarix Mascatensis Case Study: Kheir Abad Desert in Sirjan

One of the most important processes in the future of aeolian landscape especially nebka in arid environment is vegetation. This paper has evaluated the relationship between vegetation morphology and nebka morphometry in Kheir Abad desert in Sirjan Kavir. Dominant species that has formed nebka is Tamarix mascatensis. This shrub has adapted with conditions of aeolian transition area. Results of of regression analysis showed a strong significant relation between volume of aeolian dune and vegetation horizontal parameter with 0.90 of determination index and 0.60 of standard deviation estimated error. In the next stage the correlation between nebka volume and volume of plant 0.84 coefficient of determination and 0.76 of estimated error value. Also results indicated a weak significant correlation between volume of dune and vertical parameters of plant with determination index of 0.50 and estimated error of standard deviation of 1.34. Therefore the best relation between nebka dune and vegetation morphology was explained intentionally with Tamarix mascatensis canopy cover.
