Abstract: This study took abandoned land of desert steppe located in Siziwangqi and Wuchuan County as study objects to study how herbaceous community was influenced by different restoration measures and periods. The results showed that planting Caragana intermedia in the abandoned land of Siziwangqi and Medicago sativa in that of Wuchuan County could promote restoration succession of the zonal vegetation and increase the coverage and aboveground biomass of herbaceous community. With the increase of abandoned time, the number of total species, perennial herb species and annual and biennial herb species, and Shannon-Wiener index and Margalef index of plant community in the abandoned land of the two areas tended to decrease, while the zonal dominant species dominated the community gradually. Additionally, the coverage and biomass of plant community showed a trend of first decrease and then increase with the increase of the abandoned time. Therefore, the reasonable artificial disturbance in desert steppe would be beneficial for vegetation restoration of the abandoned land. The vegetation recovery of the abandoned land is a long process, so the abandoned land should be used cautiously.
