Abstract:: Afforestation is an important biological measure to address climate change and slowdown carbon dioxide emission. In this paper, field survey was carried out in Moyu’s Eco-Industrial Area in the west arid zone, and the soil physiochemical properties and the artificial vegetation conditions were studied. The results showed that soil bulk density ranged from 1.15 g/cm³ to 1.55 g/cm³ and the coefficient of variation (C_V) value is 9.75%, the maximum relative water content is only 3.89%, the averages of organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus and available potassium are 1.205 g/kg, 0.081 g/kg, 0.553 g/kg, 20.762 g/kg, 9.705 mg/kg, 0.960 mg/kg and 129.727 mg/kg, respectively. Their C_V values are 22.149%, 35.615%, 6.590%, 6.187%, 108.505%, 36.843% and 53.894%, respectively. As a conclusion, it shows that the soil characters are low moisture content, deficient nitrogen and phosphorus, relatively sufficient potash but still lack in specific regions. Besides, most of artificial vegetation is in the breeding period, and survival rates are more than 60%. These pioneer tree species of artificial vegetation have high survival rates. All of populations are increasing perimeter-class, needing timely irrigation and fertilization. There are two mixed configurations worth promoting, one is Elaeagnus oxcarpa Schlecht.+P.bolleana, the other is Elaeagnus oxcarpa Schlecht.+Ulmus pumila Linn.
