Abstract: In order to reveal spatial distribution patterns and the relationships of the species of shrub community in Alashan desert, the author selected the 12 shrub community (quadrat area 5 m×5 m) in Alashan desert as the object of this study to analyze the spatial distribution patterns from the stand scale. The results showed that: the space distribution of shrub community in Alashan desert was mainly aggregated distribution. The most aggregated shrub community were Convolvulus tragacuthoiedes, Salcola passerina, Caragana stenophylla, Ceratoides latens; Zygophyllum xanthoxylum, Tetraena mongolica were followed by randomly distributed; just Ammopiptanthus mongolicus had followed uniform distribution. From the interspecific association, there was significant positive correlation between Zygophyllum xanthoxylum, Oxytropis aciphylla and Ammopiptanthus mongolicus. The most of shrub community in Alashan desert were negative association.Key words：ALaShan Deserts; Distribution Pattern; Interspecific Association
