Abstract The variance ratio, χ2 test and Ochiai index (OI) based on the 2×2 contingency table, and the detrended correspondence analysis (DCA) were used to analyze the interspecific associations among 21 main species in the Artemisia songarica communities in Junggar Basin, China.The χ2 test results showed that 125 species pairs showed positive correlation in a total of 210 species pairs among 21 species, while the other 85 species pairs showed negative correlation.The 53 species pairs in the 125 species pairs showed significantly positive correlations, and 4 species pairs in the 85 species pairs showed significantly negative correlations.The variance ratio of overall association between 21 main species was 2.726, indicating significantly positive association.There were markedly positive correlations between A.songarica and its companion species, but OI values were relatively low.Interspecific associations among most companion species were weak (OI<0.4), indicating independent and random distribution of the species.There were significantly positive associations between dominant species, namely Hyalea pulchella, Ceratocarpus arenarius, Carex physodes, Erodium oxyrrhynchum, Schismus arabicus and Alyssum linifolium, and the OI values were also the largest, indicating they had similar ecological requirements.The distance between the species and the species' locations in the DCA figure confirmed the relationships between the species.In a word, although the habitats of A.songarica communities were different, the relationships among the species were generally stable, and the community was in a relatively stable development state, which was favorable to A.songarica population distribution and community development.
