Through field vegetation investigation in the marginal zone of the Badain Jaran Desert, the vegetation characteristics and species diversity were analyzed by calculating the species diversity indices, evenness indices and dominance indices based on important value. The results indicated that: (1)There were 37 kinds of plants in the region, and the shrubs and half- shrubs were the most among the species which the important value is larger than 0.1 in each area. (2)ANOVA showed that the Shannon-Wiener index, Simpson index, richness index and dominance index of eight regions are significantly different. The Shannon-Wiener index and Simpson index of 5 and 7 area are significantly lower than other regions because of their single specie communities. (3)Each diversity index of the shrub synusia was not significantly different in eight areas, however, there was difference in the herb synusia. The shrub and herb synusia did not show significant differences since the desert area's rare species and a small number of vegetation. (4)Due to Badain Jaran Desert's lower species diversity and fragile ecosystems, we should concern about the various ecological restoration of vegetation during the ecosystem reconstruction of the areas around Badain Jaran Desert.
