Abstract In this study, patterns of leaf traits of 30 plants in inter-dune lowland in the Mu Us Sandy Land were investigated to detect their difference among functional groups and relationships among each trait. The results showed that the variation coefficient of specific leaf area(SLA) of 30 plants was the highest among the 7 leaf traits measured. Pearson correlation showed that SLA was negatively correlated with leaf dry matter content(LDMC). However, LDMC was positively correlated with leaf carbon concentration(LCC). Leaf nitrogen concentration(LNC) was negatively correlated with the ratio of carbon and nitrogen(LC/N). There was no significant correlation between leaf area and other leaf traits. One-way ANOVA analysis showed that SLA, LDMC, Leaf Area, LNC, and LCC were significantly different among the functional groups, however, no significant difference was found for LC/N. Our results would be helpful for understanding the role of environmental changes on the plant population in inter-dune lowland of Mu Us Sandy Land and enhancing the knowledge of vegetation evolution characteristics of inter-dune lowland.
