Abstract There are different interactive relations between soil and vegetation in different plant community succession stages. The variations of soil moisture, nutrients and vegetation cover in desert-oasis ecotone, desert edge, and desert hinterland were investigated in the southern edge of Junggar Basin in Xinjiang. The results show that vegetation coverage, soil moisture, and soil nutrient content are significantly different among different landscapes (P<0.05). Vegetation coverage, soil nutrient content represent an order of desert-oasis ecotone>desert edge> desert hinterland, and soil moisture content declines from desert-oasis ecotone (10.4%), desert edge (5.8%) , to desert hinterland (3.5%). The correlation analysis indicates that there is a significantly positive correlation between vegetation coverage and soil organic matter, total soil nitrogen for the same soil.
