摘  要:
We investigated the distribution, characteristics and formation of saline soils in HeXi Zolang region. The effects of desalting and amelioration were obvious by using a biotic-measure, to plant salt-tolerant weeping alkaligrass. After planting 3-4 years, the desalinization ratio reached to 77.0 to 84.6%, pH value decreased from 8.5 to 8.2, apparent density decreased at a range from 0.14 to 0.21g/cm 3 , the total porosity increased from 5.29 to 7.93g/kg, and granular-structure increased from 23.14-32.33%
