There are three stages in the stabilization process of sand dunes, namely mobility, semi-fixed and fixed. Agriophyllum squarrosum, Artemisia halodendron and Cleistogenes squarrosa are the dominant species of communities on mobile sand dunes, semi-fixed sand dunes and fixed sand dunes, respectively. Main adaptive characteristics of Agriophyllum squarrosum include flat-shaped seeds and rapid growth of embryo roots after germination. The vigorous growth of Artemisia halodendron in semi-fixed sand dunes is promoted by positive growth reaction to sand burial promoting growth, rapid reaction to changed soil water conditions and perennial growth. Cleistogenes squarrosa is adapted to the arid conditions of stabilized sand dunes due to its (ability) to increasing root biomass.
