Present research was conducted with the aim of determination of significant effect of soil properties on natural regeneration of Haloxylon aphyllum and correlation coefficient and linear relation between soil variables and natural regeneration of Haloxylon aphyllum. Firstly, geomorphologic units were prepared in the areas under cultivation of Haloxylon aphyllum in Ardestan. Two cultivated lands in Heidarabad and, Shamsabad were selected for sampling. Then, random systematic sampling was carried out in each of these lands. For this propuse, Thirty quadrates to size 10 × 10 m were for sampling and offsprings resulted from regeneretion of planted Haloxylon aphyllum plants were counted and, further, samples were taken form the soil in some locations for me measurements on physical variables (clay, sand and silt percentages)and chemical variables (Electrical conductivity, acidity, organic carbon, nitrogen and exchangeable Sodium) . Results form such studies indicated that soil natural regeneration is significantly different in two regions of Heidarabad and Shamsabad at 1% level. Among soil physical and chemical variables, silt percentage had the highest effect compared to other variables, and also, physical variable were appeared to be effective factors on natural regeneration. There was a linear relation and negative correlation between the percentages of clay, silt, Electrical conductivity (EC), organic carbon, nitrogen and exchangeable Sodium (Na) with natural regeneration. Besides, results indicated the existence of a stright linear relation between the percentage of sand and the level of natural regeneration.
