Abstract: The autogenic succession process of vegetation in Mu Us Sandland is from Psammochlou uillosa + Agriophyllum arenarium (Artemisia sphaerocephala) on semi-drift-sand dunes to Artemisia ordosica + Sabina vulgaris on semi-fixed-sand dunes, then through S. vulgaris + Poa sphondylodes on fixed-sand dunes and S. vulgaris on fixed dunes of subclimax stage to S. vulgaris + moss community on old-fixed-sand dunes, which maybe pass to a Stipa bungeana steppe finally. The S. vulgaris community succession contains progressive and regressive succession. Species diversity increased with the development of the progressive succession, and the ecological environment began getting wet. Along with the declining of S. vulgaris, some plants exited, species diversity decreased and the habitat of community began getting dry.

Key words: community characteristics, Sabina vulgaris, Mu Us Sandland, succession
