Abstract

Environmental crisis and the consequent loss of natural resources are the main reasons which force managers to pursue methods to manage risks and solve environmental tensions. This study was conducted in SAMAD-ABAD as a center of wind erosion located in the southern part of SARAKHS region, Islamic Republic of Iran, near the Turkmenistan border and the Tajan River. Following field investigations and satellite imagery analysis, the study area was determined. Using 6 transects (3 upwind and 3 leeward), each 100 m long, we measured NEBKHAS’ morphometric characteristics (including height, length & volume) and plant characteristics (including height, perimeter & volume). Fourteen NEBKHAS were analyzed for each species (Stipagrostis, Alhagi and Peganum). In a comparative analysis of NEBKHAS associated with Stipagrostis, Peganum and Alhagi using TOPSIS model, the final weight was calculated as 0.434, 0.521 and 0.055 for Alhagi, Peganum and Stipagrostis, respectively. Therefore, as clearly explained by the TOPSIS model, Peganum is revealed to be the most suitable plant species for stabilizing moving particles in the region followed by Alhagi and Stipagrostis. Regarding NEBKHAS’ morphometric characteristics and plant morphological features as the input criteria for AHP model, the results showed Peganum to be the most suitable species for stabilizing moving sands followed by Alhagi and Stipagrostis. Stipagrostis NEBKHAS, with an average weight of 0.073, showed the least efficiency and desirability. Therefore, it was concluded that the observed result was due to this species’ undesirable morphological traits compared with the two others species in the study. Consequently, developing the landscape cover by this species is not advised.
