Abstract A new kind of sand barrier, which was composed of domestic sludge, could promote vegetation recovery of moving dunes in Minqin Country, Gansu Province. The seeds of Artemisia scopara were sown in the surface of sludge. The vegetation types, coverage, growth status and other recovery indicators were investigated. The effects of different treatments (sludge sand barrier, overlying sediment barrier, under cover of sediment barrier) of vegetation restoration were analysed. The results showed that: the biomass, coverage and height of artificial Artemisia scopara and natural Agriophylluma squarrosum, under the sludge (except Agriophylluma squarrosum) were significantly higher than the control (p <0.05). The cover, height, abundance and biomass (except demisting saltbush) of fog Atriplex suaeda and Salsola were greater than control. The highest species richness was found in grid sand barrier plots. And then the species richness in the surface of sand was greater than the area under the sand. Shannon diversity index and Simpson diversity index showed the following sequence, sludge squares>overlying sludge on sand surface>sludge under sand>control. And the Pielou uniform index was sludge squares>overlying sludge on sand surface>sludge under sand>control. Considering the cost of mixing sludge, quantity and the recovering effect, we recommend use sludge squares to fix dune and to rehabilitate vegetation in cold and arid area.
