%X <p>To explore the adaptability of plants to the environment and provide a theoretical basis for the restoration and reconstruction of vegetation in Minqin oasis-desert transition zone， 20 kinds of main plant were used， 6 functional characters of leaves were determined， variation characteristics and correlation of leaf traits were analyzed， and the difference of leaf traits of different functional groups were compared respectively. The results showed that： ①There were interspecific differences and different degrees of variation in leaf traits， the variation range from 14.11% to 47.63%， the variation coefficient of ChlC was the largest， while that of LCC was the smallest. ②LDMC with ChlC or LCC showed extremely significant positive correlation（<i>P</i>&lt;0.01）， ChlC with LCC showed extremely significant positive correlation（<i>P</i>&lt;0.01）， while the correlation between other leaf traits was not significant. ③There were significant differences in leaf traits among different functional groups. LDMC， ChlC and LCC in legumes were significantly higher than those in chenopodiaceae plants（<i>P</i>&lt;0.01）. The SLA of herb leaves was significantly higher than that of shrub plants（<i>P</i>&lt;0.01）. SLA and LNC of annual plants were significantly higher than those of perennial plants（<i>P</i>&lt;0.05）. The LDMC of perennial leaves was significantly higher than annual leaves（<i>P</i>&lt;0.01）. The content of C in leaves of perennial plants was significantly higher than that of annual plants（<i>P</i>&lt;0.05）. LDMC and ChlC of C<sub>3</sub> plants were significantly higher than that of C<sub>4</sub> plants（<i>P</i>&lt;0.05）. The δ<sup>13</sup>C of C<sub>4 </sub>plants was significantly higher than that of C<sub>3</sub> plants（<i>P</i>&lt;0.01）. LCC content in leaves of C<sub>3</sub> plants was significantly higher than that of C<sub>4</sub> plants（<i>P</i>&lt;0.05）.</p>
