Abstract: The researches indicate that Artemisia halodendron grows rapidly at the initial stage of artificial vegetation establishment, with the largest rate at the second year and maximum coverage at the third year. After 15 years, it is replaced by successional plants such as Cleistogenes squarrosa etc.. At the meanwhile, seedlings of Pinus sylvestris var. mongolica grow up between stripes and form a relatively completely structured artificial vegetation ecosystem. Sand dunes are completely stabilized at the second to third year of vegetation establishment when the optimum wind-sheltering effect of Artemisia halodendron brings into play.
