Abstract: The characteristics of soil trace elements and impact of trace elements on vegetation distribution were studied through the field survey in the two study areas A and B of the southern edge of the Badain Jaran Desert. The results showed that: The differences of 0-20 cm and 20-40 cm of trace elements concentration were not significant, while there were significantly differences between study area A and B. By the Least-significant difference (LSD), the difference of trace elements of 0-20 cm and 20-40 cm were similar both in study area A and B. The relationship of trace elements and vegetation characteristics showed that, in 0-20 cm Ba and Ce concentration significantly affected the shrub layer, Ni, Cu, Ga, As, Rb and Pb were the mainly impact factors on the herb layer. 20-40 cm, only the relationship of Cu and the herb layer richness index was significant. Stepwise multiple regression of vegetation distribution and soil trace elements also confirmed the significant effects of Ba, Ce concentration on herb layer, and Ni, Cu on shrub layer.

Key words: Badain Jaran Desert, trace element, spatial distribution, vegetation characteristics
